Navigating Decompression Safety: Your Crucial Role


In the realm of decompression management, WorkCover Queensland underscores the importance of planning dives conservatively and consistently with recognized dive tables. These tables encompass DCIEM tables, Buhlemann tables, those approved by recreational dive training organizations, and dive computers used in accordance with manufacturers' instructions.

For high-risk diving work, decompression management must align with the stipulations in AS/NZS 2299.1: 2015 Occupational diving operations – Standard operational practice.

WorkCover Queensland emphasizes minimizing factors predisposing divers to decompression illness, such as depth, physical condition, exertion, alcohol/drug use, and previous incidents. Additionally, considerations like multiple dives, cold conditions, prolonged hot showers, and flying after diving should be approached cautiously.

Regarding flying after diving, WorkCover Queensland advises a waiting period, recommending a 12-hour wait for any pressurized flights and a 24-hour wait for multiple dives or decompression stop diving. Specific guidance is available from selected dive tables.

Determining maximum diving depths is crucial to mitigate risks. AS/NZS 2299.1: 2015 guides high-risk diving work, while recognized dive tables dictate depths for general diving work. Recreational diving has specified maximum depths for various categories, emphasizing adherence to individual qualifications and experience.

Ascent training and multiple ascents within a dive profile may increase decompression illness risks. Recreational dive workers should limit teaching to one class per 24 hours to minimize ascents.

Decompression stop diving poses additional risks, and guidance from AS/NZS 2299.1: 2015 is vital for high-risk diving work. For general diving work, recognized dive tables specify requirements, and recreational technical diving demands emergency gas placement, ascent rate control, detailed dive plans, redundant breathing systems, and alternate ascent systems.

WorkCover Queensland stresses the necessity of emergency plans to identify signs of decompression illness, provide appropriate first aid, and seek medical advice for prompt evacuation to a recompression facility if needed.
