Entrapment hazards such as nets, lines, kelp, unstable structures or terrain, and confined spaces. Diver trapped underwater and may run out of breathing gas and drown. Inappropriate response due to panic is possible. Snagging on lines, nets, wrecks, debris or in caves.
Confined space training outlines the skills and protocols for safe entry to confined spaces, and includes precautions such as locking and tagging out connecting piping, testing of breathable air quality, forced ventilation, observation of workers in the space, and a predetermined rescue plan with appropriate safety harnesses and other rescue ...
They include confined water and open water sites, chosen to suit the specific training requirements. [65] Initial skills training is restricted to confined water, a diving environment that is enclosed and bounded sufficiently for safe training purposes. This generally implies that conditions are not affected by geographic or weather conditions ...
The buddy diver is less effective when insufficiently skilled, inattentive, or unfit. Buddy and team diving procedures impose a significant additional task loading on the divers, particularly in adverse conditions, such as darkness, low visibility, confined spaces, strong currents, cold water and unfamiliarity with each other's equipment and ...
Hazards like entrapment and drowning to asphyxiation and toxic chemical exposure results in the deaths and injuries that occur in these confined spaces. [16] Physical and atmospheric hazards due to confined spaces can be avoided by addressing and recognizing these hazards before entering in the confined spaces to perform work. [17]
Potable water diving is diving inside a tank that is used for potable water. This is usually done for inspection and cleaning tasks. A person who is trained to do this work may be described as a potable water diver. The risks to the diver associated with potable water diving are related to the access, confined spaces and outlets for the water.
This is the water that runs off streets and soaks into the ground. The other type, confined in aquifers many hundreds of feet deep, is the water that we tap for drinking.
Benign conditions, sometimes also referred to as confined water, are environments of low risk, where it is extremely unlikely or impossible for the diver to get lost or entrapped, or be exposed to hazards other than the basic underwater environment. These conditions are suitable for initial training in the critical survival skills, and include ...
