Validity

The current applicable Working Conditions Catalogue part: Diving work and part: Caisson work and other work under hyperbaric conditions including the WOD-SOE were approved by the CCvD of SWOD on 20 March 2018 and are effective as of 1 October 2018.               

The first Working Conditions Catalogue part: "diving work" and part; "caisson work and other work under hyperbaric conditions" came into force on 7 October 2010 after a positive assessment by Inspection SZW.

The employers and employees have agreed at that time that the Working Conditions Catalogue will be evaluated after periods of 3 years. It can then be looked at whether major changes have taken place in the kind of work, or the guidelines or working methods. And that may be a reason to adjust the contents of the Working Conditions Catalogue accordingly.

The employers and employees may jointly decide that an interim update is necessary, such as on account of investigation results and recommendations after accidents during working under hyperbaric conditions. In addition the knowledge and technique evolves constantly, which also may lead to actualisation of the Working Conditions Catalogue.

In mid-2013 a Foundation Working under Hyperbaric Conditions (SWOD) project group started updating the Working Conditions Catalogue Working under Hyperbaric Conditions  and writing of the Working under Hyperbaric Conditions System- and Maintenance Requirements (WOD-SOE), which is now part of the Working Conditions Catalogue. In the spring of 2014, this version of the Working Conditions Catalogue was assessed positive by Inspection SZW, following which the revised version came into force.

In 2015, the SWOD Project Group Working Conditions Catalogue started a new update of the Working Conditions Catalogue under Hyperbaric Conditions and the WOD-SOE, which were approved by the CCvD of SWOD on 20 March 2018.

In this Working Conditions Catalogue are amongst others included more detailed minimum control measures for working at locations with pressure differences (Delta P), working with oxygen enriched mixtures and oxygen and the use of the high-pressure jetting equipment by diving personnel.

In the document Working under Hyperbaric Conditions System- and Maintenance Requirements (WOD-SOE) amongst others the minimum requirements for a LARS and the safety requirements for the use of oxygen-enriched breathing gases have been expanded.

Management

SWOD's Central College of Experts (CCvD) manages the Working Conditions  Catalogue. The CCvD includes representatives of the civil sector, the fire brigade and defence. Together they will monitor developments in the work field under hyperbaric conditions and, if necessary, amend the Working Conditions Catalogue and, if applicable, have it assessed by the Inspection SZW.
