"Breathing apparatus" refers to a device or equipment designed to provide breathable air in environments where the air is unsafe to breathe, such as in situations with toxic gas, smoke, or at high altitudes. It is commonly used by firefighters, rescue workers, divers, and certain industrial workers. Breathing apparatus can be various types, including:
-
Self-Contained Breathing Apparatus (SCBA): A device worn by individuals, which includes a tank of compressed air, a mask, and a regulator to ensure breathable air supply.
-
Air-Purifying Respirators (APRs): These use filters to remove contaminants from the air, suitable for environments where the air is breathable but contains particulates or toxic gases.
-
Oxygen Tanks: These are used in situations where oxygen levels are insufficient or in medical situations.
-
Diving Equipment: Such as scuba gear, which allows divers to breathe underwater.
The choice of breathing apparatus depends on the specific environment and hazards present.
