Which part of the SCBA mask should be inspected prior to use?

Inspecting the face seal of the SCBA mask prior to use is essential because it directly impacts the effectiveness of the breathing apparatus. The face seal is the component that forms a critical barrier between the user's face and the external environment, ensuring that any contaminated air does not enter the mask. If there are cracks, defects, or any damage to this area, it can lead to air leaks, compromising the user's safety and the mask's performance during operations.

Maintaining a proper fit is crucial for the SCBA to function effectively, as an inadequate seal can result in exposed skin areas to hazardous materials or atmospheres. This reinforces the importance of checking the face seal before each use to ensure it will provide a reliable fit and optimal protection in emergency situations.
