A Safety for Operational Supervisors SCC diploma (SOS-SCC) shows that you have a basic knowledge of safety, health and the environment and that you can apply this knowledge in the interests of yourself and those you manage.

What and for whom

An SOS-SCC diploma shows that you have basic knowledge of safety, health and the environment and that you can apply this knowledge. In this way, you increase both your own safety and that of the people you manage. You are familiar with laws and regulations, can recognise dangerous situations and actions and know how to prevent them. You are also a fully-fledged point of contact for clients, management and employees. In short: with SOS-SCC you show that you know what is expected of you.

SOS-SCC deals with the same subjects as B-SCC, but from the point of view of the operational manager. Compared to B-SCC, SOS-SCC requires more knowledge in certain areas. This knowledge is also more application-oriented. Not only do you need to know what safe behaviour is, but you also need to know how to encourage it. And you need to know not only when to use personal protective equipment, but also which equipment to use and how to use it.

SOS-SCC is intended for operational managers and freelancers who work as subcontractors for an SCC-certified company. This includes both permanent and temporary employees.

Are you a freelancer who hires yourself out as a temporary employee (with a best-efforts obligation)? Then you do not necessarily need SOS-SCC: in principle, B-SCC is sufficient. Are you an intermediary or manager at a temporary employment agency? Then you should have SIS-SCT rather than SOS-SCC.

Four reasons for obtaining an SOS-SCC diploma

1. Staying healthy

now and in the future

2. Taking care of your colleagues

so that they too can work safely and healthily

3. Developing yourself

as a skilled worker

4. Undertaking challenging work

because you are capable of tackling these challenges

Think in terms of risk

“For me, safety is when my colleagues and I return home as healthy as when we started work. I am alert to the safety of my colleagues, think about how I can work safely and make sure that I do not take unnecessary risks. In short: think in terms of risks, that makes the work safer for all of us.”

Michael Herfst, Steigerbouw van der Panne Rotterdam


The steps marked * are optional.

Discuss with your employer what is required of you with regard to safe and healthy work. Jointly decide what you still have to learn and whether this includes SOS-SCC. Discuss how you can acquire the required knowledge and experience. There are all kinds of options available, from induction programmes to on-the-job training and from training courses to coaching. We want to give you one tip: you cannot learn how to work safely and healthily from a book!

It is not compulsory to take a training course, but it is highly recommended. Every trainer may offer SCC training courses. All you need to do is quickly search on Google to see that there is a wide choice of training courses. How can you find out which training course you should take? We have a number of useful tips for this. Once you have chosen a training course in consultation with your employer, you can start the course.

A training course usually includes the examination. Your trainer will arrange this for you. If you would like to register to take an examination yourself, please contact a recognised examination centre nearby. Examinations take place daily and throughout the country. Would you like to take a mock examination first? Visit the website of VCA Infra. You can read more about examinations here.

If you passed the examination, you will be presented with an SOS-SCC diploma. This is automatically registered in the Central Diploma Register (website in Dutch). Employers and clients can check this register to see whether you have obtained a diploma. Do you have a personal safety logbook? Please also record your new diploma in the logbook.

The diploma is valid for ten years. After that, you will have to re-sit the examination. You need to keep track of this yourself. You can check the period of validity of your diploma in the Central Diploma Register (website in Dutch).

In practice

If you have an SOS-SCC diploma, your employer or client can expect you to ensure that you and your colleagues work safely, that you are alert to risks and that you will take action to manage these risks.

Your SOS-SCC diploma is valid for ten years. After that, you will have to re-sit the examination. You need to keep track of this yourself. You can check the period of validity of your diploma in the Central Diploma Register (in Dutch). Your diploma is only valid if it is registered in the Central Diploma Register.


Do you already have a diploma in Intermediate or Higher safety management? Then you are exempted for SOS-SCC.

SOS-SCC and other countries


The Netherlands and Belgium have a long tradition of cooperation in the field of Safety, Health and Environment Checklist Contractors (SCC). As a result, Belgium now uses exactly the same system as the Netherlands. Dutch and Belgian SCC diplomas (including SOS-SCC) are therefore equivalent and valid in both countries.


You can work with your SOS-SCC diploma in France on the condition that you start working there under the authority of a VCA Petrochemicals-certified company. Also, your diploma cannot be older than four years. If your diploma is older than four years, you must first take exam again before you can work in France.

Germany and Austria

You can often work with your SOS-SCC diploma in Germany and Austria. This is ultimately at the discretion of your client. Conversely, in principle the German and Austrian variants of SOS-SCC are also accepted here, again at the discretion of the client.

Other countries

Other countries do not (as yet) use safety systems comparable to SCC. In principle, your diploma is not valid there, just as SOS-SCC variants from other countries are not valid in the Netherlands.


The cost of the SOS-SCC diploma depends on several factors. Are you taking a training course or are you only sitting examinations? What kind of training course or examination is it? Did you pass the examination the first time or did you have to re-sit the examination?

Taking a training course

A SOS-SCC training course, including the examination, costs about 225 Euros per day. There are one-day and multi-day training courses. One-day courses are particularly suitable for people who already have a great deal of practical experience. Multi-day courses offer more time to practice and let the material to sink in. A comprehensive SOS-SCC training course takes three days. Longer courses are suitable for people with little experience, who are not yet familiar with working in the Netherlands or who have difficulty learning, reading or writing. There are also courses in a language other than Dutch, the costs of which may vary from one language to another.

You only take the examination

A separate SOS-SCC examination costs about 70 to 100 Euros. This may include a free resit examination. A reading examination or an examination in another language costs about 20 to 50 Euros more.

The amounts mentioned are only an indication. Do you want to know exactly what is possible and what it costs? Then ask your trainer or examination centre. They will be happy to tell you more.
