Which of the following describes the weight of a full 5500 psi 45-minute cylinder?

The weight of a full 5500 psi 45-minute cylinder is 13.95 lbs. This specification is critical for firefighters as it helps in understanding the physical demands when carrying and using the equipment. Knowing the weight is essential for effective gear management and ensuring that firefighters can maintain optimal mobility while also being adequately supplied with breathable air.

The 5500 psi designation indicates the pressure capacity of the cylinder, and a full cylinder is designed to hold air at that high pressure for approximately 45 minutes of use, depending on the person’s breathing rate and the conditions of the environment. Familiarity with the weight can assist firefighters in training and prepare them for real-life situations where they must manage this gear effectively.

Understanding the weight of such equipment can influence decisions on storage, transport, and overall apparatus design in the fire service, underpinning the importance of this knowledge in training and operational readiness.
