What should be checked when assessing the functionality of an SCBA?

The proper assessment of a Self-Contained Breathing Apparatus (SCBA) involves checking the pressure levels and the overall condition of the equipment. This ensures that the SCBA is fully functional and ready for use in an emergency situation. Checking the pressure levels confirms that the air supply is adequate and within safe operating limits, which is crucial for the user's safety. Additionally, assessing the overall condition involves inspecting for any physical damage, leaks, or wear that could compromise the SCBA's effectiveness.

Focusing solely on visual appearance does not guarantee that the SCBA is operational, as it might have functional issues not immediately visible. Evaluating the time of use is relevant for understanding how long the SCBA has been deployed, but it does not provide real-time information about the current functionality or readiness of the equipment. While weight and balance are important for comfort and usability, they do not directly relate to the safety and operational readiness of the SCBA, making them secondary to pressure and condition checks.
