Diving Medical Advisory Council

The Diving Medical Advisory Council (DMAC) is an independent organisation of diving medical specialists, mostly from across Northern Europe which exists to provide expert advice about medical and some safety aspects of commercial diving. The advice is published in the form of guidance documents, which are made available for download.

The committee has also issued position statements on the following subjects:
 * Commercial Diving and Health (October 2006)
 * Health Surveillance of Commercial Divers (April 2008)
 * Exercise Testing in Medical Assessment of Commercial Divers (October 2009)
 * Requirement for Air Diving to 50 msw in Commercial Diver Training (March 2013)
 * Deep Saturation Diving (April 2013)
 * Education and Training in Diving Medicine (November 2014)

Courses
DMAC approves training courses in diving medicine which comply with the requirements of the joint committee of the European Committee for Hyperbaric Medicine (ECHM) and the European Diving Technology Committee (EDTC) "Training Standards for Diving and Hyperbaric Medicine", which specifies: Level 1 - Medical assessment of divers (Medical Examiner of Divers), and Level 2D - Medical management of diving accidents and illnesses (Diving Medical Physician).

Use of DMAC guidance documents
Canadian association of diving contractors members are required in terms of CSA Z275.2-15 Occupational Safety Code for Diving Operations Items 8 and 9, to comply with DMAC guidance documents for surface-supplied offshore gas and oil diving and deep diving, including mixed gas and saturation diving.
