Bij nood & ongevallen

Dear colleagues,

Heijmans considers health and safety to be extremely important. Every Heijmans’ employee, supplier and subcontractor is entitled to a safe working environment. Together, we have to guarantee such an environment. This guide on ‘Safety, Health, Welfare and Environment’ (SHWE) will provide you with all basic information on how to work in a safe and healthy manner.

We expect you to familiarise yourself with the safety rules with which you must comply when working for Heijmans. We also expect you to seek out additional safety information, in case it is needed to carry out your work. Thus, we expect a proactive attitude. Ensure that you work safely and provide for the safety of your colleagues and other people working around you.

In 2013, we launched the GO! safety programme in order to take safety to the next level. GO! stands for ‘Geen Ongevallen’, which means No Accidents in Dutch. The GO! safety programme is based on three pillars:

  1. Attitude and behaviour: because safety starts with you, and your own attitude and behaviour with regard to safe working.
  2. A clear and uniform safety level and image, unambiguous processes and the same rules for everyone. This manual is an integral part of this approach.
  3. Cooperating on safety in the construction chain. As everyone can do their bit to improve safety. From the client to the subcontractor and from the designer to a construction operative.

Use this Safety, Health, Welfare and Environment guide as a reference work, so that you know what is expected of you. This way, all of us will contribute to creating a safe working environment. Together, we can become the safest builder in the Netherlands. But, for this, we do need everyone to commit!

With kind regards,
Ton Hillen
Chair of the Executive Board
Heijmans N.V.

1Safety at Heijmans

A safe and healthy work place. With respect for people and the environment. Excluding specific risks and hazards. That is what Heijmans stands for.

1.1Our safety programme GO!

Working in the construction industry entails risks. Therefore, safety is key at Heijmans and the business combinations that we are a part of. It goes without saying, that all our business units and combinations are VCA** certified. But safety is more than just complying with the rules. It is about awareness and behaviour: taking responsibility for what you do, so that you and your colleagues can work in safe conditions. Because nobody wants an accident.

GO! No accidents

This is why we have established the GO! safety programme.
The three main pillars of the programme are:

  • Changing of attitude and behaviour in regards to safety.
  • Achieving a uniform safety level and image throughout the entire organisation.
  • Cooperating on safety throughout the chain. From the client to the subcontractor. From the call for tender up to execution.
A safe and healthy work place. With respect for people and the environment. This does not only include preventing accidents, but also working in a sustainable manner. Both for your own health and a healthy environment.

Always work with approved equipment and tools!

In this booklet, you will find the basic information you need to work in a safe and healthy manner. Would you like to learn more about certain topics? You will find more specific information in our so-called toolboxes. These provide in-depth information on numerous safety issues (click for more information). The toolboxes can be viewed in the GO! app (click for more information) or can be requested at the K&V (Quality & Safety) department.

Note: this information is not optional!
It may seem obvious, but safe working starts with you. We expect you to comply with the rules and guidelines in this guide and stated elsewhere. And that, if necessary, you will actively seek out additional information in order to work safely. But also, that you will address colleagues about unsafe behaviour. Whether you are working on a construction site or in the office: follow the Six Rules for Attitude and Behaviour (click for more information).

1.2The GO! app

Have you already downloaded the GO! app on your smartphone? The GO! APP includes safety information, toolboxes, newsletters and the option to report unsafe situations. The GO! APP is publicly available, so not just to Heijmans’ employees. Everyone can read the information and report an unsafe situation.

GO! Information
All information on the GO! programme can be found in the GO! app by pressing the ‘GO! informatie (information)’ button.
Clicking this button will show you all toolboxes from the toolbox meetings. You can view and download them, so you use them for your own toolbox meeting.
You can report unsafe situations by clicking the ‘melden’ (report) button. For instance, a hole on a construction site that has not been closed off. There is much we can learn from reporting unsafe situations and it helps us to prevent accidents in the future. Therefore, always report an unsafe situation. Would you like to know more about reporting via the GO! app? Read more.
The SHWE (Safety, Health, Welfare, Environment) guide can also be found in the GO! APP.
Update in de keet (site cabin)
The GO! programme includes a monthly newsletter. It contains safety figures and information on current issues. Would you like to view or download these newsletters? You will find them in the GO! app.
The LMRA: Last Minute Risk Analysis. The steps to be taken are always on hand in the GO! APP.
Emergencies & Incidents
Is there an emergency or incident at your work place? The button ‘bij nood & ongevallen’ will show you what to do and whom to inform.
Courses and Instructions
The GO! app also contains courses, instructions and exams on safety. For instance, the safety film.
Are you organizing a work place inspection? The GO! app will provide you with the questionnaire which you need to conduct the inspection.

The GO! app can be found in the app store on your smartphone or online via www.geenongevallen.nl.

The BIG 6: the six biggest risks

Accidents continue to occur on a regular basis. We want to see an end to that! There are six types of accidents, which account for 80 percent of all our accidents.
We call them the “BIG 6”:
1 slips and trips
2 falling
3 falling objects
4 impact with protruding objects
5 entrapment
6 getting hit by flying particles

These are frequently occurring risks. So, include them in your LMRA (click for more information).

1.3Who can you turn to?

Various people and departments within Heijmans work on safety.

  • At the project, the (Senior) Site Manager is primarily responsible. He informs and instructs employees. For instance, through ‘start work’ / project instructions, working meetings and toolbox meetings. He also monitors the safety measures and agreements and carries out work place inspections. Furthermore, he ensures that unauthorized people cannot enter the work place. Lastly, you can turn to him in case you have a complaint.

  • The GO! Coach is a colleague involved in the execution of project, who will help you increase safety awareness. He will do so by:
  • helping you to initiate health and safety discussions;

  • by identifying new safety issues and bringing them to the attention of others;
  • by initiating actions which will improve the safety of our work.

Do you have a safety issue? Are you having trouble resolving it yourself? Or are experiencing a conflict with regards to this issue? The GO! Coach can help you. Approach the GO! Coach if you see him on site. You will be able to recognize him by the GO! logo on his helmet. His name and mobile number can be found on the alarm card.

  • The emergency response officer(bedrijfshulpverlener/BHV) is a specially trained member of staff. He provides first aid in the event of accidents. He is also involved in evacuations and firefighting. You must always follow the instructions of the emergency response officer. He can be identified by the logo on his helmet.

  • You can contact the Integral Safety Department with any safety-related questions.

  • The Safety Advisor identifies risks and assesses work situations. The Safety Advisor also investigates accidents and near misses and provides support to colleagues and management. Furthermore, the Safety Advisor/Prevention Officer informs/provides advice to the VGWM (SHWE) commission of the Central Works Council.

  • The VGWM-commission of the Central Works Council critically monitors management’s safety policy. It is also the point of contact for employees.

  • Are you sick? If so, you must report this to your Site Manager or Line Manager. They will help you get back to work quickly. Additionally, you need to report sick to Heijmans’ Arbo Service Centre or to your own company, in accordance with the associated procedures.

  • The Arbodienst (Health & Safety Service) organizes the PAGO (periodic occupational health check) and the PMO (periodic medical check). Furthermore, the Arbodienst organizes targeted periodic research (gericht periodiek onderzoek/GPO) and inspections for specific occupations and activities.

  • Are you experiencing bullying, violence, sexual harassment or discrimination? In this case, your Line Manager is your first point of contact. Should you feel like you are not being heard or would you rather talk to someone else? Then you can contact your confidential counsellor.
Manual Human Resource Management (HRM)
This VGWM guide overlaps quite a bit with the manual Human Resource Management. In the HRM manual you will find information on:
  • Employee benefits
  • Company arrangements (code of conduct; education; working hours; night and weekend work)
  • Legal regulations
  • Development interviews
  • Additional information with regard to SHWE (including alcohol, drugs and smoking policy and psychosocial workload)

2General requirements and rules

Working safely starts with you. As a Heijmans’ employee, you are obliged to work carefully and cautiously. You are responsible for your own safety and the safety of your colleagues. For this reason, we work in accordance with fixed regulations and rules.

2.1General rules at work

Before you start

  • Park only in the designated areas. Bear in mind that parking in public parking facilities might cause disturbance to the immediate surrounding area of the project.
  • On arrival at the start of a project, report to your Line Manager. Ensure that you have valid proof of identity with you (passport or ID card) at all times.
  • Follow the designated walking and driving routes within the project.
  • Check the applicable rules and the evacuation procedure for the project location (this can be the safety film).
  • Always use the required personal protective equipment and ensure that it is properly maintained.
  • Check that equipment/tools have been approved before using them. They must carry a valid inspection sticker.
  • At certain projects there is a check in and check out procedure. If so, follow this procedure.

During the work

  • Use and maintain the provided safety facilities in the correct manner. And never modify or remove these.
  • Using a phone during work can result in dangerous situations. Do not use your phone while operating (electric) tools and while operating (driving) machines/ machinery. Do you need to make a phone call during work? Make sure you are standing in a safe place. Do not endanger others. And keep a close eye on your surroundings.
  • Only smoke in the designated areas. Smoking is prohibited in the work place, canteen and at the office.
  • Working while under the influence of alcohol or drugs is strictly prohibited. Use of medication should be reported to the Site Manager/Line Manager.
  • Also adhere to the Road Traffic Act at project locations; respect the traffic rules and observe the maximum speed limit. Park only in the designated areas.
  • Work places, cabins, canteens and toilets must be kept clean and tidy. No waste or residual materials may be left behind on the work place.
  • Keep access routes to and from your working place on the project clear.
  • Limit the amount of waste you generate. Separate waste and place it in the correct container or waste bin. Burning of waste is not permitted in any circumstances.
  • Clean up any spillages of waste using suitable materials. Inform your Line Manager of any spillage of substances hazardous to people or the environment.
  • Prevent any leakage of oil or fuels.
  • Do not allow machines or equipment to run unnecessarily.
  • Avoid unnecessary use of heating and lighting.
  • Avoid making unnecessary noise during your work.
  • Avoid damage to flora & fauna.
  • Carry out repairs, maintenance and cleaning work at the designated location. Use the prescribed equipment and facilities.

Upon completion of work

Always tidy up the work area and store materials and tools in the correct manner and in the right place.

Under the age of 18?
Then special, stricter rules will apply to you. You may not carry out all types of work. Furthermore, different rules apply to you with regards to working hours and rest periods. Aged 15? Then you may only work under continuous supervision of your Line Manager. Aged 16 or 17? Your Line Manager must provide regular supervision.

2.2Instruction and information

Heijmans devotes a lot of time to instructing staff and visitors. As an employee, you are obliged to take part in instruction sessions. You must also comply with the verbal instructions of your Line Manager at all times.


Are you new at Heijmans? Then, you will receive a general introduction, covering topics such as safety, health, welfare and the environment.

In addition, your Line Manager will provide you with specific project instructions for each project. All safety risks will be covered. It goes without saying that we will do everything that is possible to reduce these risks. To this aim, we have developed various methods:

  • A Health, Safety and Environmental Plan is drawn up for each project. It lists all risks regarding health, safety and the environment. The plan also sets out the control measures in place. Your Line Manager will discuss the elements which are relevant to you.
  • Sometimes, you will need to carry out tasks which are new to you. Tasks which do not occur frequently. Or tasks which bring with them an elevated level of risk. In these cases, the Project Team, Site Manager or Safety Advisor will draw up a Task Risk Assessment (TRA). It will set out the risks associated with the specific task. Your Line Manager will discuss the TRA with you.

Last Minute Risk Assessment (LMRA)

In the end, you are, obviously, responsible for your own safety. The Last Minute Risk Assessment (LMRA) serves that purpose. The LMRA is a final check before you get to work.

In order to complete the LMRA process successfully, you need to ask yourself the following questions:

  • Do I know exactly what I need to do and can I do it in the way described?
  • Have I taken part in a ‘start werk’ (start work) instruction session dealing with the risks involved in my work?
  • Am I aware of the potential risks and how I can prevent them?
  • Do I know what I need to in order to carry out the work safely and are the necessary resources available (e.g. tools, Personal Protective Equipment)?
  • Are the environmental circumstances such that I can carry out my work in safety?

The “one two three” of the LMRA!

1 Assess the risk
Do not start working straightaway, but first check if there are any risks present.
2 Take control measures
Consider what needs to be done to remove these risks and take those measures.
3 Start work!
You can now work safely.

Does the LMRA indicate an unsafe situation? Report this via the GO! APP.


Are you expecting visitors? You will be responsible for their safety.

  • Visitors to a project location must always first report to the Site Manager. He will provide safety instructions.
  • Do you work in an office? Then you will collect your visitor at the Reception yourself. When the visitor leaves, you will accompany him on his way out.

Toolbox meeting

During the so-called toolbox meetings, one or several current topics regarding safety will be discussed. You can also suggest a topic yourself. Of course, the success or failure of a toolbox meeting depends on the commitment of the participants. So, make sure you take an active part in these meetings. Then stick to what was discussed during the meeting. You will also be able to find toolbox meetings in the GO! APP (click for more information). In case you would like to suggest a topic that does not tie in with one of the available toolboxes, please contact the K&V (Quality & Safety) department.

Training and education

Everyone working on site must at least have the Basic Safety VCA certificate. Furthermore, you will take part in additional safety training courses. The required courses depend on your role and on the project you are working on. You will also receive additional training for specific tasks that involve many risks.

Safety passport

If needed your Line Manager will request a safety passport for you. It will list the safety courses you have taken and your medical records. Has your situation changed somehow? Then you need to report this to your Line Manager.

3Personal protective equipment

We use personal protective equipment (PPE) to protect ourselves while we are working. Certain items are mandatory at all times. Other PPE is required for specific tasks or situations. You can read below what PPE is required and when. For certain projects, there are additional general requirements regarding the use of PPE. For instance, reflective trousers or safety glasses. At a project, you will be informed on site about which PPE are mandatory at all times.

3.1Mandatory PPE

You are required to wear a safety helmet, safety footwear and reflective clothing on all construction sites1. You must also have safety eyewear within reach. See Figure 1.
1. A construction site is defined as a work location within construction fences, a work station, yard or production site.

In case of poor visibility (evening, night, snow, mist, etc.), both reflective long trousers and a jacket or pullover with long sleeves are mandatory. See Figure 2.

Are you working alongside the railway? In that case, it is mandatory to wear safety footwear, a helmet and yellow reflective clothing. See Figure 3.

But do note, the colour of required PPE when working working alongside the railway will change to orange per 1 July 2019.

When carrying out service work in operational buildings2 ,it is mandatory to at least wear safety footwear. See Figure 4.
2. An operational building is an office, home or another type of space that is not enclosed by construction fences or barriers.

3.2What standards are to be met by PPE?

Specific requirements and standards apply to PPE.
Therefore, do not purchase PPE yourself, but order them via your employer. PPE is to be used and maintained in accordance with the instructions provided.



  • Always wear work clothing provided by your employer. If needed, you will be provided with fire retardant and anti-static clothing.
  • Always wear long trousers.
  • Wearing a T-shirt at all times is a minimum requirement.

Reflective clothing

  • Reflective clothing is to meet Class 2 at all times (safety tabard, Figure. 1).
  • When working alongside the road, reflective clothing is to meet EN ISO 20471 Class 2 and the RWS standard (orange safety tabard). In case of poor visibility (evening, night, mist or rain), clothing is to meet Class 3 (orange safety trousers and jacket). See Figure 2.
  • When working alongside the railway, reflective clothing is to meet the EN ISO 20471 Class 2 and the Prorail standard (yellow safety tabard). In case of poor visibility (evening, night, mist or rain), clothing is to meet Class 3 (yellow safety trousers and jacket). See Figure. 3.
    Do note: the colours of PPE will change per 1 July 2019.

Safety helmet

Heijmans’ safety helmets feature standard foldaway safety glasses.
Do you wear glasses? Then you can order prescription safety glasses.
Wear a helmet that is not older than 5 years (ABS). The manufacturing date is stated inside of the helmet.

Safety eyewear

Safety eyewear must fit closely to the face. Safety eyewear must be worn during all metalworking processes3, when there is a spatter hazard and when working with hazardous substances.
3. Milling, tapping, turning, filing, drilling, sawing, boring, broaching, polishing, honing, lapping, planing and slotting.

Safety footwear

Safety shoes or boots must meet class S3 or S5.
This means that the shoe or boot:

  • has a hard toecap.
  • has a hard midsole.
  • has antistatic properties.
  • has an antislip tread.
  • is watertight (S3 increased water resistance/ S5 watertight).

The following additional requirements apply:

  • High tops are required on construction sites
  • S5 safety boots are required where soil contamination is present.
  • Low safety shoes are allowed when carrying out service work.
  • Special asphalt footwear is required where asphalt is being laid.

Other PPE

Other PPE must be worn in specific situations. These requirements are set out against those specific activities and situations in Section 7 of this booklet. Or in the VGM (SHE) plan of the project or the business unit. The following PPE must be worn in any event in the situations described.

Hearing protection
Hearing protection is to be worn where noise levels exceed 80 dB(A), which is comparable to the noise level of very heavy traffic. Ear plugs are available at the site cabin. If desired, you may order ear muffs or may request plastic earplugs to be made for you (via your own company).

The use of suitable gloves is mandatory when working with chemicals (as indicated on the Safety Information Sheet) or with sharp objects. This also applies to welding, cutting and burning.

Respiratory protection

  • Do you see dust? Then that represents an immediate risk. Combat dust formation at the source, by extraction or by adding water. If that is not possible, an FFP-3 dust mask is to be worn.
  • Do you work with gases or chemicals? Then wearing the correct type of respiratory protection is mandatory.

Fall protection
Before working with fall protection gear, you must be instructed about how it works and how it is to be used.

You must be connected to a safety line in the following situations:

  • When working at heights exceeding 2.5 metres and edge demarcation is not an option. And when working closer than 4 metres from the edge.
  • When working from a mobile elevating work platform or manriding basket. The fall protection is to be secured to a suitable attachment point.
  • You must also use fall protection gear working below 2.5 metres, edge protection is not an option and the area below is not free of obstructions.

Check the available toolboxes for more information on this.


  • Wearing a lifejacket is mandatory when working above water.
  • It is not allowed to work alone above and within 4 metres from the water.
  • A lifejacket must also be worn when working near water (less than 4 metres), if no edge protection is provided.

3.3Exceptions to mandatory PPE

When there is a customized PPE policy at a project, it will always be complimentary to the basic PPE.
For instance:

  • Long reflective trousers are required. See Figure 5 and 6.
  • Wearing safety eyewear required at all times.

4Safety symbols

We use a fixed set of safety symbols in order to communicate risks in a clear manner. These symbols are easy for everyone to understand. We use fixed colours and shapes for accompanying safety signs.

  • Yellow indicates a warning: take care! Warning signs are always triangular.

  • A sign with a red border indicates a prohibition. Prohibition signs are always round.

  • Blue indicates an order, something you must do. Order signs are also round.

  • Green signs indicate assistance. These signs are rectangular.

  • There are also signs providing information or instructions. These are always blue and square.

  • Firefighting equipment is indicated by red squares.

4.1List of safety symbols

This Section describes the most common signs used at Heijmans. Study these frequently.


An unsafe situation, accident or environmental incident can always occur, despite all the safety measures in place. You must know what to do in such situations.

5.1Alarm card / Company emergency response plan

There is an alarm card at each (project) location. It states:

  • who you need to call.
  • what you must do.
  • who the emergency response officers are.

Ensure you know where to find the alarm card, so that you will be able to check it in case of an emergency. Furthermore, make sure you know where to find the designated assembly point, the defibrillator, the First Aid box, the fire extinguishers, etcetera.

The following requirements apply should an emergency arise:

  • Strictly follow the instructions of the (internal/ external) emergency services.
  • Switch off work equipment or have it switched off.
  • In case there is no danger, shut off any gas or oxygen lines and cylinders.
  • Ensure that construction and emergency access routes are clear of obstacles for the emergency services.
  • Leave the work place as calmly and quickly as possible and head for the assembly point.
  • Do not provide information to people who are not working on the project and avoid panic.
  • Have your name checked off at the assembly point (do not leave for home!).


  • Is anyone injured? If so, have, if necessary, first aid provided by an emergency response officer (BHV).
  • Immediately report the accident to your Line Manager.
  • Follow further instructions on the Alarm Card.
  • Take photographs of the situation and record the accident in IRES (incidents registration system).

5.3Environmental incidents

Damage to flora and fauna, undesirable substances in the air, ground or water: all examples of environmental incidents.

  • Take immediate measures to limit further damage to the environment.
  • Immediately report the environmental incident to your Line Manager.
  • Follow further instructions on the Alarm Card.
  • Take photographs of the situation and record the environmental incident in IRES (incidents registration system)

5.4Report via the GO! app

Are you encountering an unsafe situation? Reporting it is mandatory, so that we can learn from the incident. Make an initial verbal report to the Site Manager. This should then be followed up with a digital report via the special GO! app. This app allows you to digitally record an unsafe situation, and especially the solution you came up with to make the situation a safe one. The app is used to record photographs, control measures and the location of the situation. This way, we can keep track of the situation and learn from it. You can download the GO! app via the App store on your smartphone (search for “Heijmans” and “GO”). You can also access the app directly via the internet: (www.geenongevallen.nl)

In order to make a report, you must first register. Do this as follows the first time you use the app:

Step 1
Open the GO! app, fill in your name, telephone number, email address and your relationship with Heijmans.

Step 2
Upon registration, check your email. You will receive a password and further instructions by email (sometimes this mail goes into the junk mail folder).

Step 3
Once logged in, you can change your password via “settings”.

Step 4
Now select the project you are working on or type in a new project.

Step 5
Now you can record and report any unsafe situation on site.

6Enforcement policy

We want everyone to go home safe and healthy at the end of the day. That is why we aim for a safe working environment, safe working conditions and the prevention of accidents. This can be achieved primarily through attitude and behaviour. Therefore, we expect all employees to comply with the following 6 rules for attitude and behaviour:

The 6 GO! rules for attitude and behaviour
1 I take responsibility for my own safety and that of others.
2 I take immediate action in case of an unsafe situation.
3 I address colleagues about unsafe working practices.
4 I appreciate colleagues addressing me about unsafe working practices.
5 I report unsafe situations so colleagues can learn from these.
6 I discuss safety dilemmas with my manager.

We expect you to follow these rules. We appreciate it when unsafe situations are reported via the GO! app.


A monthly reward will be given to a team or staff member who has taken an initiative or action or has made a report contribution with regards to safety. If you know of someone who has made an outstanding contribution with regards to safety, report this via the GO! app. Because a positive contribution to safety deserves to be noticed and valued.

6.2Enforcement policy1

Heijmans assumes that you want to carry out your work safely. That you will take account of your own safety as well as the safety of your colleagues and the environment. Do you know of someone who does not do this? Then he should be addressed about his behaviour; by colleagues, his Line Manager or anyone else. Speaking up helps us improve workplace safety.

Has someone been spoken to about unsafe behaviour and is that person refusing to change his attitude or behaviour in order to improve safety? Then sanctions will follow. If someone fails to comply with safety instructions even after being spoken to, then there will be an official warning (a yellow card) or sanctions (a red card), with the associated consequences. Only the Line Manager and/ or the (Senior) Site Manager may issue such a warning or impose sanctions. The objective of the enforcement policy is to create a safe working environment for everyone. Warnings and sanctions are an essential element of this policy.

1. Every employee will be informed by HRM about the enforcement policy and the potential consequences of unsafe behaviour or actions. Subcontractors and hired personnel will be informed by Procurement.

Speaking to colleagues about safety

Anyone can miss something or make a mistake. Therefore, it is even more important that we look out for one another and speak up when we notice unsafe behaviour. This applies to everyone, your workmates, a Director, a visitor or a subcontractor. If you see that someone is not following the safety instructions, speak up. If someone fails to wear the prescribed Personal Protective Equipment (PPE). If someone smokes where this is not permitted. Or if things are not as tidy and orderly as they should be. This way, we make safety a topic that is open for discussion. And we work together to create a safer working environment.

Warning (yellow card)

Have you been spoken to about unsafe behaviour? Do you still carry on in the same manner? Or have you repeatedly overstepped the mark? This will result in an warning and an annotation in the central administrative system (IRES). The warning will also be discussed with your Line Manager / employer. The written confirmation of the warning will be included in your personnel file.

If you do not receive another warning within three months the yellow card will expire.

Sanctions (red card)

Do you knowingly endanger yourself, your colleagues or your environment? Then you do not belong at Heijmans! We want to offer a safe workplace, in which unsafe behaviour does not belong. In this case, you will be refused access to the workplace. You must also report to Management. The sanction will be recorded in the central system (IRES). The written confirmation of the sanctions will be included in your personnel file. It depends on the situation whether it is followed by a suspension, termination of the employment contract or contract with the subcontractor. Any loss of production costs (including possible stagnation costs) will be at the subcontractor’s expense.

The above procedure will also apply if you repeatedly fail to act on a warning. The same will also apply if you receive a second warning within three months of the first, if you use or are under the influence of alcohol or drugs on site (see also the HRM handbook). If you are involved in fighting or display aggressive behaviour (see also the HRM handbook). Or if you are guilty of theft.

Have you received a warning or had sanctions imposed? And do you not agree with the action taken? You can submit an objection. This can only go via the HR-manager or director. The director will take the final decision. Raising an objection will only be worthwhile if there were no clear safety instructions. If you did not demonstrably receive careful instructions about the safety rules. Or if you received the warning or sanction from someone not properly authorised to do so.

Everyone wants to go home safe and healthy at the end of a working day. And for that, we have to rely on one another. Work safely and address each other about unsafe behaviour or unsafe situations. This way we can work together to create a safer working environment for everyone.

7Specific situations

7.1Alongside the road

There are specific risks associated with work alongside the road (motorway). We therefore block off roads, using cones, beacons or concrete or steel barriers.

What can go wrong?
  • There may be a collision with a vehicle.
  • Road users may be put at risk.
  • You could be fined.
  • Other road users might follow you into the work station or the construction site.
Control measures
What must you do?

When driving into the closed off area:

  • Use a yellow/orange flashing light on the roof of your vehicle (360˚ visible).
  • Ensure that the “werkverkeer” (works transport) sign is clearly visible on the back of the car.
  • Indicate your direction clearly and in good time.
  • Reduce your speed.
  • See the figure below for the correct action.
  • Pay attention to the safety of other road users.
  • Avoid causing nuisance to other road users.
  • Place your waiver ticket behind the windscreen where it is clearly visible.
  • Only use the waiver for work purposes. Take note of additional waiver instructions.
  • Avoid filtering in to other traffic where visibility is poor (for instance, mist, snow or other circumstances that limit visibility).
  • Always wear the correct PPE (see Section 4).
  • When using the hard shoulder, the maximum speed is 50 km/h and the maximum speed difference with other traffic is 20 km/h in case other traffic is travelling slower than 70km/h.

Working within a closed lane or on a construction site:

  • Do not enter the safety zone, maintain the separation distances shown in the illustration below the text.
  • Once within the closed-off area, drive at walking pace and switch off the yellow/orange flashing light.
  • Use regular vehicle lighting and put your warning lights on when driving. (When carrying out work on the underlying road network, you must use your flashing roof light rather than your warning lights.)
  • Park your vehicle in the designated location.
  • When parked, all lights are to be switched off.
  • Wear reflective clothing.
  • Do not make changes to the traffic control measures which have been implemented.
  • Look out for moving vehicles within the closed-off zone. Make sure you are visible and make eye contact with the driver.
  • When working behind a barrier, take account of the safe distance between your position and the barrier.
  • When road cones have been run over, do not put them back yourself.

The correct layout of the work zone is shown in the illustration below. The minimum safety distance behind the vehicle-mounted arrow board and in front of the end of the closed-off lane is 130 metres. This means that no activities may be carried out in this area and no vehicles may be parked here. The boundaries are indicated with three cones placed at right angles to the driving direction.

In the event that a road user drives into the working zone or the construction area:

  • Attempt to contact the driver.
  • Turn on the yellow/orange flashing light.
  • Stop the vehicle and inform the driver about the correct way to merge back into traffic at the end of the closed-off area. Also inform him about the required driving behaviour within the working zone.
  • Do not put yourself in danger and do not jump out in front of a vehicle in an effort to make it to stop.

Direct traffic yourself? Don’t!
The traffic situation around a closed-off lane can be chaotic at times. All the same, you must not be tempted to direct traffic yourself. It is not allowed. Discuss the deployment of an authorised traffic director with your Line Manager.

7.2Alongside the railway

Working by the railway entails specific risks. Therefore, you may only work by the railway if you have completed the appropriate training.

The two most significant risks when working by the railway are passing trains and the highvoltage overhead lines. A large number of rules have been drawn up to ensure a safe work environment. The most significant rules are:

  • Do not walk on the sleepers.
  • Do not walk on the rails.
  • Use the footpaths.
  • Stay 1.5 metres away from the rail.
  • Always report yourself on and off site.
  • Stay 1.5 metres away from the overhead line.
  • Do not store items within 1.5 metres of the rail.
What can go wrong?
  • There may be a collision with a train.
  • You could be electrocuted.

Control measures
What must you do?
  • Ensure you have your Digital Safety Passport 'Toegang tot het spoor' with you.
  • Report to the Workplace Safety Officer (LWB) or the Local Safety Officer (LLV). He will provide safety instructions and will report you on and off site (using the Digital Safety Passport).
  • Check your PPE (safety footwear, helmet, yellow reflective tabard). Only safety staff wear orange clothing. Per 1-1-2020 this colour scheme will be reversed.
  • Always follow the instructions of the safety staff.
  • Do not lean against the Physical Barriers.
  • Stay away from high voltage parts such as the overhead line or the 3rd rail (metro).
  • Do not enter the rail or pass the Physical Barriers.
  • Check if your machine (caterpillar crane / piling rig / duty cycle crane / etc.) has been properly grounded. If not, report this to your Line Manager and ground your machine before you start working.

7.3Ladders and stepladders

A ladder or a stepladder is not a workplace. It is intended to provide access to a workplace. Can you use a different, safer piece of work equipment to work from? For instance, a mobile scaffold (see Section 7.4) or a mobile elevating work platform (see Section 7.6)104)? If so, use it. If you do need to work from a stepladder or ladder (for a short period of time), then it is important that you do it safely. Therefore, follow the guidelines (see the table below the text). There are still far too many falls and other accidents due to working with ladders and stepladders.

What can go wrong?
  • The ladder or stepladder may topple or slide away.
  • You can miss your step on the ladder or stepladder.
  • You can lose your balance and fall because of the lack of a guardrail.
Control measures
What must you do?
  • Ensure the substrate is firm and level.
  • Do not place the ladder or stepladder in front of a door or passageway.
  • Secure the top of the ladder.
  • Stand on two feet and hold the ladder with at least one hand.
  • Move the ladder or stepladder if you can no longer work safely from it.
  • Use equipment to move materials.
  • Cordon off the area if necessary and do not leave the ladder or stepladder unattended.

There are specific guidelines relating to the use of ladders and stepladders. The table shows precisely when you can work from ladders or stepladders and when not.

What must you look out for at all times?
  • Items to be carried up a ladder or stepladders must be shorter than one metre.
  • Items to be carried must weigh less than 10 kilograms.
  • Do not work from ladders or stepladders when the wind force is 6 or higher or in case of slipperiness.

Want to know more?
See the toolbox ‘Ladders or stepladders’ or the A-sheet 'Ladders en trappen' (only available in Dutch).

7.4Mobile scaffolds

Mobile scaffolds are widely used in construction for fitting and installation work. We prefer to make them as light as possible and with the smallest possible footprint. This makes them easier to handle. Mobile scaffolds are constructed and assembled in such a way to give them adequate strength and stability. You may erect a mobile scaffold yourself, provided you have been properly instructed and work in pairs. Assembling a mobile tower scaffold is not without risks.

What can go wrong?
  • The scaffold can collapse due to overloading.
  • The scaffold can topple.
  • You can fall from the scaffold.
Control measures
What must you do?

During assembly

  • You must be familiar with the assembly instructions before assembling a tower scaffold. The instructions must be available.
  • Check that all components of the scaffold are complete and approved. Avoid mixing different brands or systems.
  • Always work in pairs.

During set-up

  • Set up the scaffold so that it is stable and level.
  • Ensure that the wheel brakes are on.
  • Ensure the working platforms are complete and that they are fitted with an upper and middle rail and a toeboard.
  • Use the stabilisers. These are mandatory if a second level is added.
  • Never place a ladder or auxiliary scaffold on the working platform.
  • Do not attach lifting equipment to the scaffold.
  • Do not use a mobile scaffold if the wind force is 6 or above.
  • Never leave the scaffold unattended.

When moving the scaffold

  • Use road plates where the substrate is soft.
  • Ensure no people are standing on the scaffold.
  • Keep the stabilisers in place. If the stabilisers are not fitted with wheels, keep them clear of the ground.

Want to know more?
See the toolbox 'Mobile scaffolds' or the A-sheet 'Rolsteigers' (only available in Dutch).

7.5Fixed scaffolding

Accidents involving scaffolds occur often. Both while assembling, using and dismantling the scaffold. Accidents often occur because the user has modified the scaffold. Because the design is not suited to the way the equipment is used. Or because the scaffold has not been assembled in accordance with instructions.

Scaffolds and scaffolding equipment are therefore subject to strict requirements. Scaffolds are assembled in accordance with specific guidelines. Special expertise and skills are required. Only approved scaffolding companies are allowed to assemble scaffolds.

What can go wrong?
  • You can fall from the scaffold
  • You can trip due to equipment on the scaffold
  • You can get hit by objects falling from the scaffold.
  • The scaffold can collapse due to overloading.
Control measures
What must you do?
  • Do not modify the scaffold in any way.
  • Do not use a standard scaffold for lifting or hoisting operations.
  • Do not fit any nets, tarpaulin screens, windbreaks or the like, unless you have permission to do so following discussion with the scaffolder and submission of the calculations.
  • Lifting equipment must not be attached to the scaffold. This is only allowed when calculations demonstrate that this is permissible. And when the manufacturer of the lifting gear gives his approval.
  • A scaffold must not be undermined. If excavations must be carried out in the vicinity of the scaffold, this must be discussed with the scaffolder.
  • Do not exceed the permitted maximum load.
  • Scaffold materials must not be used as packing timbers; as pads for cranes; or to protect hoses lying on a driving lane.
  • A scaffold pole must not be used as a crowbar.

What must you look out for at all times?
There must be calculations for all assembled scaffolds and all scaffolds must be approved. An approved scaffold must carry a filled out scaffold card (recent, maximum of 2 weeks, checked). If this card is missing, the scaffold may not be used.

Want to know more?
See the toolbox on scaffolds or the A-sheet 'Veilige steiger' (only available in Dutch).

7.6Mobile elevating work platforms

A mobile elevating work platform (MEWP) can be used for working in locations that are difficult to access. A MEWP is a mobile lifting device. It has been especially designed to lift persons.

What can go wrong?
  • The MEWP may topple.
  • The MEWP may collide with something.
  • You or someone in the vicinity may get trapped.
  • You might fall from from the MEWP.
  • You might be flung out of the MEWP while it is in motion.
Control measures
What must you do?
  • You must have received adequate training and instruction. You must be aware of the operating instructions and you must possess the necessary competencies.
  • An MEWP may only be used by a person aged 18 or above.
  • The MEWP must never be used for lifting operations.
  • A belt harness with a short line must be worn at all times. The line is to be secured to a suitable attachment point on the MEWP.
  • Only hand tools and materials may be carried in the MEWP. Ensure that these items do not protrude over the side.
  • Take note of the maximum number of persons and weight.
  • Ensure that the substrate is of adequate strength.
  • The MEWP must not be operated when the wind force is 6 or above.
  • Never step out of the MEWP at height!
  • When there is a risk of falling objects, the area around the MEWP must be cordoned off.

Want to know more?
See the toolbox 'Mobile Elevating Work Platform.'

7.7Excavation work

Below ground level, you will find countless kilometres of telephone lines, pipes for water, electricity, gas and oil. As well as numerous other cables and pipes. Excavation work can be life-threatening to the person carrying out the job and the people around him.

What can go wrong?
  • Coming into contact with underground structures and pipes.
  • Chance of working in enclosed spaces.
  • Collapsing walls.
  • Falling from a height or excavated matter.
  • Working in contaminated ground.
Control measures
What must you do?
  • Only dig with permission from the Site Manager.
  • Beforehand, discuss the exact work location with the Site Manager.
  • Beforehand, ask your Site Manager or the excavation office about the presence of cables and pipes.
  • Create trial trenches or pre-puncture the ground to find unidentified cables and pipes.
  • Ensure you have a clean soil declaration.
  • Ensure the presence of a safe entrance and barriers.

Meer weten?
See the toolboxes 'Pits and trenches', 'Prevent excavation damage' and 'Working in/ with contaminated soil.'

7.8Working over or near water

Sometimes work needs to be carried out over or near water.

What can go wrong?
  • Falling into the water.
  • Drowning.
  • An injury due to falling into the water (hypothermia, fractures, wounds).
  • Getting stuck between ship-shore and ship-ship while transferring people.
  • Weil’s disease
Control measures
What must you do?
  • Put up edge protection where possible.
  • Wear a lifejacket within a radius of 4 metres from/ to the water (when there is no edge protection).
  • Work with at least 2 people.
  • Call out for help if someone falls into the water. Never go into the water yourself.
  • Arrange an adequate boarding point for transferring people.
  • Make sure you know where you can find rescue equipment (life buoy, hook, swimming ladder, etc.)

7.9Electrical and gas installations

Strict rules apply to working with electrical and gas installations. That is not surprising, as this work can involve substantial risks.

What can go wrong?

Je kunt onder stroom komen te staan:

  • by touching live electrics.
  • due to a short-circuit.
  • due to an overload.

There may be various consequences, from a severe shock and burn injuries to heart problems and brain damage.

  • A fire may break out.
  • There may be an explosion.
Control measures
What must you do?
  • Ensure the installation is not electrically live.
  • The basic principle is that work will not be carried out on live electrical installations. The details are set out in NEN 3140.
  • You should contact a medical practitioner following any accident involving electricity.
  • Wear appropriate PPE. In the case of gas installations, this will include both antistatic and fire retardant clothing.
  • Smoking and open flame are prohibited in the vicinity of a gas installation.

7.10Quartz dust

Construction materials containing quartz can generate large amounts of dust when processed. The small dust particles can enter the lungs.

What is quartz dust?

Materials containing quartz dust include concrete blocks, bricks, calcium silicate brick, sandstone, cellular concrete, concrete, cement, ceramics and rubble. Quartz dust will be released if these materials are drilled, milled, polished, abraded, demolished or cleaned.
What can go wrong?

Inhalation may result in respiratory diseases, including pneumonia, pneumoconiosis and lung cancer. You might also suffer an allergic reaction.

Control measures
What must you do?
  • Choose the working method which will generate the least amount of dust.
  • Use tools with extraction and/or water damping.
  • When using water damping alone, an FFP3 dust mask is to be worn. It is possible to still inhale dust via the water spray.
  • Do not remove extraction equipment from tools. Neither when that makes the work easier.
  • Provide adequate ventilation and a clean working floor.

Want to know more?
See the toolbox ‘Quartz dust'.


The use of asbestos is now prohibited. In the past, it was used extensively in construction work. For instance, as sheet material in roofs, floors, walls and ceilings, as pipe cladding and as water pipe. Asbestos is frequently found in buildings that were built before 1994.
In construction asbestos was primarily used:

  • in sheet materials used in facades, roofs, floors, walls and ceilings.
  • in ducting for ventilation and the removal of flue gas and sewer pipework.
  • in sprayed form on steel structures and on ceilings.
  • as insulating cladding on pipework and boilers.
  • as gasket or (cord) packing material in casings and central heating installations.
What can go wrong?

Asbestos consists of tiny fibres, which can be extremely harmful if inhaled.
Asbestos particles are released if the material is drilled or sawn.

Control measures
What must you do?
  • If you unexpectedly come across asbestos you should immediately suspend the work. Cordon off the contaminated area and report the matter to your Line Manager.
  • You must under no circumstances work on asbestos on your own initiative. And you must never remove it yourself. A certified specialist company must always be engaged for such work. This will be arranged by the Project Management / Site Manager.

The above rules apply if you come across asbestos unexpectedly. Of course, it can also happen that we know in advance that a project will involving work with asbestos. In this case you will receive specific instructions.

Want to know more?
See the toolbox 'Asbestos'.

7.12Contaminated soil or groundwater

The ground or groundwater may contain substances that do not belong there. For example, heavy metals or chemical products. These may be hazardous. In the event of ground contamination, a Deskundig Leidinggevende Projecten (DLP) must be present and measures must be taken in accordance with CROW 132.

What can go wrong?

The risks depend on the substance in the ground.

Control measures
What must you do?
  • You must always report to the Line Manager at the location and follow his instructions at all times.
  • Ensure that you know what contaminants are involved and take the appropriate control measures.
  • Eating, drinking and smoking are prohibited at the location.
  • Are you taking a break, to eat, drink, smoke or go to the toilet? You must then remove any contaminated clothing and wash your hands.
  • Wash your hands when leaving the location.
In most cases you will know in advance when you will have to deal with contaminated soil or groundwater. However, you may also come across it unexpectedly.
  • If you suspect that you have encountered contaminated soil or groundwater, you must suspend the work immediately.
  • Report anything unusual you see or notice to your Line Manager. For example, unusual smells.

Want to know more?
See the toolbox ‘Working in/with contaminated soil’.

7.13Hazardous substances

You may come into contact with a variety of hazardous substances during your work. For instance, flammable, poisonous, oxidising, corrosive or irritating substances.

What can go wrong?
  • Hazardous substances may be damaging through contact or inhalation.
  • Certain types of hazardous substances may explode.
Control measures
What must you do?
  • Flammable, toxic, oxidising, corrosive or irritating substances must be stored in a fire-resistant cabinet or storage container. A maximum of 150 litres may be stored in a cabinet, while a maximum of 500 litres may be stored in a container.
  • A working stock of such materials may of course be kept available. This will be the quantity required for 1 day's work. If the working stock is 50 litres or above, then the package containing it must be placed over a liquid-tight leak tray.
  • The cabinet or container must always be locked.
  • Ensure that the cabinet or container is properly ventilated.
  • Ensure that a "No Smoking or Open Flame" sign is placed on or close to the door.
  • Make sure the packaging is intact and properly labelled.
  • Hazardous liquids are to be placed over a leak tray of adequate capacity.
  • Check that hazard information sheets are available (on paper or on the intranet).

How can you identify hazardous substances?

You can identify hazardous substances by the symbols on this page.

Want to know more?
See the toolbox ‘Hazardous substances’.

7.14Machinery, equipment and electrical hand tools

During your work, you will frequently have to deal with equipment, machinery and electrical tools of all kinds. For instance, circular saws, table saws, grinding machines, welding equipment or a stud gun.

What can go wrong?

Each machine and piece of equipment has its own specific risks. In general terms, the most significant risks are these:

  • You may be injured. For example, due to rotating components or improperly maintained equipment.
  • You may suffer damage to your hearing from working too long in excessively noisy situations.
  • You may inhale hazardous dusts or vapours, for example wood dust or plastics.
  • The item you are working on may catch fire.
  • You may experience excessive heat.
  • You could be electrocuted.
Control measures
What must you do?
  • Always read the manual before using equipment. Know what you must do and what to look out for.
  • Check the toolbox about the machine, equipment or tool in question.
  • Always use the additional personal protective equipment prescribed.

Want to know more?
See the toolboxes on various materials, machines and the toolbox 'Electrical hand tools'.

7.15Enclosed spaces

Crawl spaces, storage tanks, cellars: there are times when you will need to work in an enclosed space.

What can go wrong?
  • You may become unwell or suffocate due to a lack of oxygen.
  • You may receive an electric shock.
  • Toxic, flammable or explosive liquids may be present.
  • When something goes wrong, an enclosed space is often difficult to access.

Control measures
What must you do?
  • Properly ventilate the room. Measurements must be carried out in advance if hazardous vapours may be present or if the oxygen level may be too low.
  • Use safe voltages: safety transformers, 42V lamps and battery-powered hand tools.
  • Always work in pairs. The second person will act as a watchman and raise the alarm in an emergency. The watchman must never enter the enclosed space in case of an emergency. Contact must be maintained using two-way radios or mobile phones.
  • Note the dimensions of a crawl space. It must be a minimum of 80 cm in height.
  • The entry hatchway or hole must be at least 62 x 80 centimetres. The hatchway or hole must be clearly cordoned off.
  • An exit route of maximum length 18 metres is to be provided between the entrance and the working place.

Want to know more?
See the toolbox 'Enclosed spaces'.

7.16Solitary working

Do you sometimes work alone? Beyond the vision or hearing range of others? Or where contact with other people is impossible? This is deemed to be "solitary working".

What can go wrong?

Generally, a lone worker faces faces many of the same (accident) risks as someone who works with others. However, working alone means you will not be able to rely on colleagues in the event of danger or an accident. This increases the risk level.

Control measures
What must you do?
  • See whether solitary working can be avoided.
  • Identify the risks involved in carrying out the work. As well as any circumstances which would result in an elevated risk level in case of solitary working. Take any additional measures necessary. For example:
  • Report in and out using the phone or other means of communication. Or arrange for a continuous audio connection.
  • Wear an electronic protection device, which sends out an alarm if the person wearing it has not moved for a specified period.
  • Ensure there are options to raise alarm.
  • Ensure all exit routes are clear.
  • Ensure that keys and similar equipment are visible and within reach.
  • Make sound agreements with the people at home and with your Line Manager about how to respond if you fail to return home.

Prohibitions on solitary working

In some cases, there is an absolute prohibition on solitary working. This is the case when:

  • Working in a room containing a high voltage electrical installation (over 1,000 VAC or 1,500 VDC). Where the components are not or are not adequately protected against direct or indirect contact or excessively close approach.
  • Working in an enclosed space with a risk of asphyxiation, intoxication, poisoning, fire or explosion.
  • Diving work.
  • Working in compressed air.
  • Work by young people under the age of 18 years.

A second person must be present during such work. The most important tasks of this second person are to monitor events and to organise assistance if something goes wrong during the work.

Want to know more?
See the toolbox ‘Solitary working’.

7.17Horizontal and vertical transportation

By horizontal and vertical transportation, we mean work with forklift trucks as well as lifting machinery (i.e. a cranes and hoists). Moving heavy loads is risky: an error can have severe consequences.

You may only work with a forklift truck or lifting equipment if you have received proper training.

What can go wrong?
  • You might be struck by a falling object.
  • You might get trapped.
  • You might collide with persons or objects.
  • The vehicle might tip over.
Control measures
What must you do?
  • • You must never walk beneath a suspended load.
  • Do not exceed the permitted safe working load for a machine.
  • Inspect items like chains and lifting slings before use. They must be approved and must not exhibit any damage.
  • Forklift trucks and lifting machinery must not be used to lift people.
  • Ensure that any lifting equipment is placed on firm foundations/supports.
  • When in the vicinity of vertical or horizontal transport equipment, ensure that you have been seen by the driver.

Want to know more?
See the toolboxes on 'lifting'.

7.18Physical loading

Sometimes it is necessary to carry a load without the use of equipment. Good posture is extremely important in such circumstances.

What can go wrong?

You might get injured due to incorrect lifting, bending, pulling or pushing.

Control measures
What must you do?
  • Avoid manual handling of loads wherever possible.
  • Do not bend and lift unnecessarily. Use tools and equipment to move materials.
  • Do not lift excessively heavy loads. Ask colleagues for help with large or heavy items.
  • Keep the load as close to your body as possible. Avoid excessive reaching.
  • If possible, place heavy materials and tools at working height rather than on the ground.
  • Avoid lifting with a twisted back. Stand directly in front of the load and let your feet do the turning.
  • Lift steadily and keep your back as straight as possible.

Want to know more?
See the toolbox ‘Physical loading (lifting)'.

7.19Plants and animals

During work, you may come into contact with plants and animals. As a construction company we comply with the Flora and Fauna Code of Conduct. The aim of the Code of Conduct is to protect vulnerable animals and plants.

What can go wrong?

Plants may be damaged and animals may be harmed or killed.

Control measures
What must you do?
  • Do not uproot plants.
  • Do not kill, injure, catch or disturb animals.
  • Do not disturb or destroy nests or dens.
  • Do not collect eggs.

The breeding season
Take account of the breeding season for birds (15 March to 15 July).

Want to know more?
See the toolbox 'Flora en fauna’.

7.20Office Work

When we think about safety at work we usually think first about the construction side of things, but office work has its own specific risks. We have therefore drawn up a number of rules relating to office work, which we must all adhere to. Some of the most significant requirements are listed here.

What can go wrong?
  • Physical ailments due to incorrect posture when sitting for extended periods of work on a computer.
  • Dirty or untidy work location.
  • Reduced productivity.
  • Stress.
  • Fatigue.
Control measures
What must you do?
  • Set up your workplace in the correct way.
  • Place your display screen at the correct height.
  • Use a mouse rather than a touchpad.
  • A djust your seat correctly and place the desk at the correct height.
  • Keep your workplace clean and tidy.
  • Take adequate breaks, this relieves stress and keeps you productive.
  • Let management know if the pressure of work is excessive. A healthy amount of pressure is beneficial, but call a halt if it all becomes too much.
  • If you feel that you or colleagues are experiencing excessive pressure of work, discuss this with colleagues, management or the confidential counsellor (see Section 3.1).

Want to know more?
See the toolbox 'Office work'.

7.21Weather conditions

The weather can have major effects on safety at work. Unfortunately the weather is beyond our control, so agreements have been drawn up about how to respond for example to snow, heavy rain or storms.

What can go wrong?

The risks created by weather are very diverse, ranging from extreme cold with the potential risk of hypothermia, extreme heat, electrocution, interruption of power supplies or tripped fuses due to lightning through to slips and falls due to slippery conditions caused by snow or ice.

Control measures
What must you do?
  • Watch the daily weather forecast and take any necessary preventative measures against the consequences of extreme weather, including wind, rain and snow. Suitable clothing may be required for example.
  • Where the construction site is inaccessible due to snow, ice or rain it must be made accessible before work may commence.
  • If there is less than 10 seconds between lightening and thunder during a storm, seek a safe place of refuge.
  • Safe places of refuge include buildings, site cabins, cars or mobile machines.
  • Keep away from metallic objects like cables, radiators, fencing, lampposts, cranes, scaffolds and other equipment.
  • Pull the plug on electrical tools.

Want to know more?
See the toolboxes on 'weather conditions'.

7.22Unexploded ordinance

Despite prior investigation, it is possible that you will encounter explosives in the ground.

What can go wrong?

Risk of explosion.

Control measures
What must you do?

Have you found explosives or ordinance in the ground? Then do not touch it, but immediately contact the 'Bodemspecialismen' (ground specialisms) department at Heijmans.

7.23Biological agents

You may come into contact with so-called "biological agents" during your work. These include viruses, bacteria, fungi and parasites. They can be found almost anywhere. For instance, in sewage or grass.

What can go wrong?

Contamination or infection can lead to serious illness.

Control measures
What must you do?

Let op je persoonlijke hygiëne

  • Eating, drinking and smoking are prohibited at the workplace.
  • Cover any open wound with a waterproof plaster.
  • Wear protective work clothing, safety footwear and work gloves.
  • After work, wash your hands with disinfecting soap.

Do you come into contact with sewage water during your work? Then you can make use of the vaccination programme Hepatitis-A and DTP. Ask your Line Manager about this. (At Heijmans, the Arbo Service Centre can provide more information on this).
