What is the typical duration of air supply for a standard SCBA cylinder?

The typical duration of air supply for a standard SCBA cylinder generally falls within the range of 30 to 60 minutes. This duration can vary based on several factors including a user's physical activity level, the cylinder's pressure, and the specific model of the SCBA. Standard SCBA cylinders are commonly designed to hold high-pressure air that can provide a sufficient air supply for firefighting operations or hazardous environments for an estimated 30 to 60 minutes, allowing firefighters and responders to perform critical tasks while ensuring their safety. Understanding this time frame is essential for effective planning and operation during emergencies where air supply is crucial.
