What pressure rating is typical for SCBA air cylinders designed for approximately 30 minutes of use?

SCBA (Self-Contained Breathing Apparatus) air cylinders designed for approximately 30 minutes of use typically have a pressure rating of 2200 psi. This pressure allows firefighters to access a sufficient air supply while operating in environments where breathing can be compromised, such as smoke-filled rooms or hazardous atmospheres. The 30-minute rated cylinders are commonly used in various firefighting situations, giving firefighters the duration needed to perform their tasks efficiently while ensuring their safety.

The specifications for SCBA cylinders are critical as they determine the functionality and duration of use while maintaining a safe environment for the user. At a pressure of 2200 psi, the cylinder is designed to hold a volume of breathable air that can sustain a firefighter for the necessary amount of time during operations. This pressure rating balances the needs for portability, weight, and the air supply needed for effective performance in emergency situations.
