Compressed air breathing apparatus, otherwise known as a self-contained breathing apparatus (SCBA), is a vital piece of equipment used to protect firefighters, police officers, and industrial workers from hazardous substances, such as smoke, that can be present in the atmosphere.

Compressed air breathing apparatus consists of a face mask or full hood, a compressed air tank and regulator, and a harness to keep the equipment firmly in place. The tank is pressurized with air at between 2,500 and 4,500 pounds per square inch (PSI), enabling firefighters and other users to access air for up to 45 minutes.

The main purpose of using compressed air breathing apparatus is to avoid dangerous atmospheres, enabling firefighters, search and rescue teams, emergency medical responders and other personnel to enter areas where there may be smoke, chemicals, and fire. A much lesser known, but no less important use of compressed air breathing apparatus is in industries such as welding or manufacturing, where workers need to be able to operate in hazardous environments.

Compressed air breathing apparatus are designed to provide the user with the maximum possible level of protection in the event of an emergency. The equipment is designed to be comfortable to wear, with adjustable straps and other features to ensure they fit snugly and do not become uncomfortable after long periods of use.

Compressed air breathing apparatus are a vital piece of safety equipment, and should always be used when entering an environment where air quality may be in question. By following the manufacturer's instructions, users can be sure that they are using the equipment safely and effectively, so that they can work with confidence in hazardous environments.
