OCFR Self-Contained Breathing Apparatus (SCBA) Practice Test

The type of air pressure system used in Self-Contained Breathing Apparatus (SCBA) is a high pressure system. SCBA units are designed to provide breathing air to firefighters and responders in hazardous environments, and they typically store air at high pressures, ranging from 2,200 to 4,500 psi (pounds per square inch). This high pressure allows for a sufficient volume of breathable air to be contained within a relatively compact tank, ensuring that users have access to clean air for a significant duration while they are operating in potentially dangerous scenarios.

The high-pressure system is essential for sustaining multiple operations and ensuring that first responders can rely on their breathing apparatus to function effectively in life-threatening situations. This system also ensures that the air remains clean and free from contaminants until it is needed by the wearer.
