Contribute to a safer and healthier work environment

Are you an operational supervisor for a contractor? Or are you a self-employed person without personnel working as a subcontractor? If so, you must have a Safety for Operational Supervisors SCC (SOS-SCC) diploma.

Your SOS-SCC diploma demonstrates that you have a basic knowledge of safety, health and environmental issues and that you can make use of this knowledge in practice. This improves your safety and the safety of the persons you supervise. You know about the relevant legislation and regulations, can recognize hazardous situations and unsafe actions and know how to avoid them. You are also a valuable contact person for principals, management and employees. In other words, when you have an SOS-SCC diploma you show that you know what is expected of you.

What do you need to do?

You can get - and keep - your SOS-SCC diploma in six steps. The steps marked with a * are optional.

1. Talk with your employer*

Talk with your employer about what you are expected to know about know about health and safety at work. Discuss what you need to learn and whether this includes getting an SOS-SCC diploma. Discuss how you can get the knowledge and experience you need. A variety of options are available, ranging from an introduction programme to on-the-job training and from specialized courses to coaching. However, always remember that you cannot learn how to follow healthy and safe work practices by reading a book!

2. Find and choose a training course*

A simple Google search will find a tremendous number of sites offering SOS-SCC training courses. However, how can you find out which training course you need? You can begin by asking your employer, who will usually have contacts with training institutions. You can also contact your industry association, which will be able to provide you information about training institutions with in-depth knowledge of your sector and institutions that offer training courses for your specific sector. Obviously, you can also carry out this search yourself. When you do so, look for training institutions that have expert instructors, clearly communicate the results achieved by their course participants, carry out customer-satisfaction surveys and have a complaints procedure.

3. Follow a training course*

Once you have chosen a training course in consultation with your employer you can get cracking.

4. Sit an examination

Training courses usually include the concluding examination. Your training institution will make the necessary arrangements. When you wish to register yourself for the examination you will need to contact a recognized examination centre in your area. Examinations are held daily at centres throughout the Netherlands. Do you want to sit a mock examination before the actual examination? If so, surf to the VCA Infra website (mock examination available in English).

5. Register your diploma

Have you passed the examination? Congratulations, you are now the proud owner of an SOS-SCC diploma. This is automatically entered in the Central Diploma Register. Employers and principals can consult this Register to verify that you have been awarded this diploma. Do you have a Personal Safety Logbook or a variant of this logbook? If so, make an entry of the award of your diploma.

6. Sit a re-examination

The diploma is valid for ten years. You must sit a re-examination at the end of this period. You will need to keep an eye on the expiry date. The record of your diploma in the Central Diploma Register states the expiry date.

Which subjects are covered?

SOS-SCC covers the following subjects:

1. Preparations for, discussions on and inspections of the work

  • Regulations and safety rules
  • Safe work practices, consultations and inspections
  • Prevention

2. Performance of work

  • Workplace
  • Personal protective equipment
  • Work equipment
  • Specific work and work environments

3. Control of specific hazards

  • Hazardous substances
  • Electricity and radiation
  • Fire and explosion

4. Control of incidents and emergencies

  • Accidents
  • Emergencies


These are the same subjects as those covered by B-SCC, but now from the perspective of an operational supervisor. SOS-SCC provides more knowledge about some elements of B-SCC, and the additional knowledge is of a more applied nature. You need, for example, to know what safe behaviour at work is and know how you can encourage this behaviour. You also need to know not only when personal protective equipment must be used, but also which equipment must be used and how it must be used.
