How long is the SCBA rated for usage?

The Self-Contained Breathing Apparatus (SCBA) is typically rated for 30 minutes of use in emergency situations. This duration is based on the average consumption rates of a user while engaged in strenuous activities, such as firefighting, search and rescue, or other emergency response functions. It's important to note that the actual time an individual can effectively use the SCBA may vary depending on several factors, including the user's physical condition, level of exertion, and the operational environment. Therefore, while the SCBA is rated for 30 minutes, it is always essential for users to continuously monitor their air supply and be aware of signs of fatigue to ensure their safety during operations.
