As of 1 January, 2007, the Working Conditions Legislation has undergone a significant change. The most important change as of 1 January 2007 was a further increase of the responsibility of employers and employees by having the standards drawn up by private parties.
The National Diving Centre (NDC) has at that time managed the process to develop the Working Conditions Catalogue for the field of activity working under hyperbaric conditions.
In 2010 the Working Condition Catalogue for working under hyperbaric conditions was approved by the Labour Inspectorate and came into force for the field of activity.
Since that time the NDC has placed the Working Conditions Catalogue for working under hyperbaric conditions on this site.
Since the Working Conditions Catalogue fits seamlessly into the objectives of the Foundation Working under Hyperbaric Conditions (SWOD) the Working Conditions Catalogue management was transferred to SWOD in 2012.
Mid 2013 a SWOD working group started with the actualisation of the Working Conditions Catalogue for working under hyperbaric conditions. In spring 2014 this version of the Working Conditions Catalogue was approved by Inspection-SZW, whereupon this revised version came into force.
The current Working Conditions Catalogue is supported by the Civil Sector, Defence and the Fire brigade.
The Working Conditions Catalogue Hyperbaric Medicine is still under development and will following approval be added. The objective of SWOD is to cover the complete field of activity working under hyperbaric conditions in the Working Conditions Catalogue working under hyperbaric conditions.
In this Working Conditions Catalogue as many as possible risks have been included, which may occur when executing diving work, caisson work and other work under hyperbaric conditions. For all these risks are defined which minimum control measures an employer and employee shall take to manage those risks.
New aspects in this Working Conditions Catalogue are amongst others occupational health examination requirements as well as the document Working under Hyperbaric Conditions System- and Maintenance requirements (WOD-SOE).
The WOD-SOE replaces the "Assessment Guideline governing the Maintenance of Systems for Diving and Caisson Equipment, inclusive systems for hyperbaric medicine (BRL-D&C)". The system certification requirement which was part of this guideline is now also withdrawn. With this change all parties involved have implemented deregulation, while the safety continuous to be maintained. As SWOD we are very pleased about this.
The Working Conditions Catalogue is a live document, because knowledge and technique will continue to evolve. In case you have recommendations to improve the Working Conditions Catalogue we would appreciate it very much if you could advise us. You can mail these recommendations to us, so we can look at these aspects at the next actualisation.
Working Conditions Catalogue explanation
The column Actor/ Subject contains the subdivision of the described risks. The Committee Working Conditions Catalogue for working under hyperbaric conditions have elected for a subdivision used by IMCA in the International Code of Practice for Offshore Diving.
In the column Risks are all the risks which are relevant to an Actor/ Subject. Each risk is described in a concise as possible manner.
Minimum control measure
The minimum control measures which are described in the Working Condition Catalogue are the minimum measures an employer or employee must take in order to manage the associated risk.
An employer is always permitted to take additional (more elaborate) measures.
In the Working Conditions Catalogue references have been included where relevant control measure and/ or the risk are further explained.

Application and selection type of work
In the Working Conditions Catalogue is indicated for which category of work under hyperbaric conditions the respective risk is relevant.
The website www.arbocataloguswoo.nl has a selection menu in which the user can indicate which kind of work under hyperbaric conditions he or she is going to perform. Following choosing the kind of work under hyperbaric conditions only the risks and control measures are shown which are relevant to that type of work.
Although this Working Conditions Catalogue has been made with utmost care, the Foundation Working under Hyperbaric Conditions nor the web site administrator accept any liability for any incorrect information, the possible causes and potential consequences thereof.
