response: Ah good.  There are four factors that are important for safety: dive team performance, individual diver behaviour, the environment, and the equipment.

history: I enjoy scuba diving Oh do you? Apparently the word scuba is short for self contained underwater breathing apparatus! The first time I went under water with the mask, I felt claustrophobic and was panicky Oh I see.  Apparently there can be psychological effects due to being immersed in water and being in high ambient pressure. It is definitely a very different sensation Is it?  I know also that underwater diving has physiological influences on air breathing animals. There are some physiological adaptations made underwater, both during dives where a person holds their breath, and also dives involving breathing a suitable gas supply. After getting used to it I was fine and able to enjoy myself
knowledge: The safety of underwater diving depends on four factors: the environment, the equipment, behaviour of the individual diver and performance of the dive team.
