There are serious risks involved in diving. Therefore, if your company wants to carry out diving or caisson work, you must report (Dutch) this to SZW Inspectorate (Inspectie SZW). You must also include a copy of the work plan with your report. You can use the same form for reporting both caisson work and diving activities. If you perform diving activities for mining, wind farms or mineral extraction, you must report this to the State Supervision of Mines (Staatstoezicht op de Mijnen, SodM).
When doing caisson work, you must keep a valid 'Diving and Caisson Equipment Maintenance System' certificate at the work location. A certified diving doctor must examine your employees annually in a work-related medical examination.
A spare diver and a team leader must be present at all times when diving work is carried out. The divers, spare diver and team leader must all hold the relevant work certificates. In addition, someone must be present who holds a 'Medical Supervision of Diving' certificate. All certificates must be kept at the work location. Every diver must keep a diver’s log. Specific rules for the working hours of divers are described in the Working Hours Act (pdf, page 19).
