In the realm of diving and snorkelling, participants face various hazards that may result in injuries or illnesses. WorkCover Queensland, as the overseeing body, emphasizes the importance of understanding and managing these risks through effective risk management principles.

Diverse changes in the aquatic environment, categorized as physical, physiological, psychological, or task/environmental-related, underscore the need for vigilance. PCBUs are tasked with comprehending these risks, applying risk management principles, and minimizing or eliminating risks where reasonably practicable.

Notable injuries and illnesses include medical conditions, drowning, decompression illness, barotrauma, contaminated air, nitrogen narcosis, panic, and hypoxic blackout. PCBUs must ensure that participants are aware of relevant medical conditions and seek advice or assessment when necessary. Additionally, effective supervision, rescue, and first aid systems are crucial in preventing drowning incidents.

Decompression illness, arising from ascending with excessive nitrogen, demands immediate first aid and medical attention. Barotrauma, caused by pressure changes affecting air spaces, necessitates careful equalization during descent. Contaminated air poses risks like convulsions or loss of consciousness, emphasizing the importance of regularly testing compressor systems.

Nitrogen narcosis, a drug-like effect of breathing nitrogen under pressure, can impair reasoning and coordination. Panic, linked to various factors, can compromise rational thinking underwater. Effective training and awareness help mitigate these risks. Hypoxic blackout, induced by breath-holding, requires careful consideration, especially in recreational snorkelling. Proper guidance, avoidance of hyperventilation, and vigilant supervision are key preventive measures.

WorkCover Queensland underscores the significance of effective education, training, and supervision to ensure the safety of participants engaging in diving and snorkelling activities.
