Diving safety is the aspect of underwater diving operations and activities concerned with the safety of the participants. The safety of underwater diving depends on four factors: the environment, the equipment, behaviour of the individual diver and performance of the dive team.
Diving safety – Risk management of underwater diving activities; Hazard – Situation or object that can cause harm; Human factors in diving safety – The influence of physical, cognitive and behavioral characteristics of divers on safety; Risk assessment – Estimation of risk associated with exposure to a given set of hazards; Rubicon ...
Dive safety is primarily a function of four factors: the environment, equipment, individual diver performance and dive team performance. The water is a harsh and alien environment which can impose severe physical and psychological stress on a diver.
Divers must avoid injuries caused by changes in pressure. The weight of the water column above the diver causes an increase in pressure in proportion to depth, in the same way that the weight of the column of atmospheric air above the surface causes a pressure of 101.3 kPa (14.7 pounds-force per square inch) at sea level.
The major factors influencing diving safety are the environment, the diving equipment and the performance of the diver and the dive team. The underwater environment is alien, both physically and psychologically stressful, and usually not amenable to control, though divers can be selective of the conditions in which they are willing to dive.
Physical conditions of the water or other diving medium influence the safety and practicability of a dive and can affect the choice of equipment used. These include motion of the medium, visibility and illumination, temperature, and pressure. These conditions are affected by weather, season and climate. [30] [31]
Several factors influence the diver, including immersion, exposure to the water, the limitations of breath-hold endurance, variations in ambient pressure, the effects of breathing gases at raised ambient pressure, effects caused by the use of breathing apparatus, and sensory impairment. All of these may affect diver performance and safety. [1]
