When you go scuba diving, they include extra cylinders for emergency breathing.
That's important. There is surprisingly a great deal of safety knowledge required to scuba safely, such as rising slowly instead of too quickly.
True, and for ambient pressure diving, you are exposed to all of the pressure of the water.
You mean without a scuba suit? I haven't heard of that before. Is it newer?
Yes, without a suit, though humans are not well adapted to the conditions of diving, so equipment is recommended.
Are you familiar with the depth limits of ambient pressure diving?
Diving safety
The safety of underwater diving depends on four factors: the environment, the equipment, behaviour of the individual diver and performance of the dive team. The underwater environment can impose severe physical and psychological stress on a diver, and is mostly beyond the diver's control. Equipment is used to operate underwater for anything beyond very short periods, and the reliable function of some of the equipment is critical to even short term survival. Other equipment allows the diver to operate in relative comfort and efficiency. The performance of
Diving cylinder
A diving cylinder, scuba tank or diving tank is a gas cylinder used to store and transport the high pressure breathing gas required by a scuba set. It may also be used for surface-supplied diving or as decompression gas or an emergency gas supply for surface supplied diving or scuba. Cylinders provide gas to the diver through the demand valve of a diving regulator or the breathing loop of a diving rebreather.
Diving cylinders are usually manufactured from aluminium or steel alloys, and are normally fitted with one of
