SCBA Fire Safety Breathing Apparatus is an atmospheric breathing apparatus. It allows firefighters and other emergency personnel to breathe safely in smoke-filled or oxygen-deficient atmospheres. It consists of a mask, a compressed air cylinder, a regulator, and a harness. Its face mask provides a seal around the user's face, preventing smoke and fumes from entering the lungs. This controls the flow of air from the cylinder to the face mask. Also, it is an air pack, air tank, oxygen cylinder, or general pack, mostly used in firefighting. It has a high-pressure gas storage cylinder.
