What should be checked before each use of SCBA equipment?

Before using Self-Contained Breathing Apparatus (SCBA) equipment, it is critically important to check the air supply level and the integrity of the mask. This ensures that the user has an adequate supply of breathable air and that the mask is functioning properly to provide a safe seal and protection against hazardous environments.

The air supply level must be monitored to ensure that it is sufficient for the task at hand, as running out of air can lead to life-threatening situations. The integrity of the mask is also crucial; any damage or improper fit could compromise the user’s safety by allowing harmful contaminants to enter the breathing space. Thus, checking both the air supply and the mask integrity is foundational to safe SCBA operation.

Other factors, such as personal identification cards, weather conditions, or the color of the equipment, may have their importance in certain contexts but do not directly impact the immediate functionality and safety of the SCBA apparatus itself in a life-threatening environment. Therefore, the verification of air supply and mask integrity is paramount before each use.
