What checks should be performed just before donning SCBA facepieces?

• A. Check ambient temperature and humidity levels
• B. Check air cylinder gauge and test PASS device
• C. Review operational procedures and firefighter safety rules
• D. Confirm team readiness and equipment maintenance

Answer: (B)

Before donning Self-Contained Breathing Apparatus (SCBA) facepieces, checking the air cylinder gauge and testing the Personal Alert Safety System (PASS) device is essential for several reasons. The air cylinder gauge indicates the amount of breathable air available, which is critical to ensure that the firefighter has sufficient air for the duration of their operation. A proper check of the air supply helps prevent situations where a firefighter could run out of air while engaged in high-risk activities, such as firefighting or rescue operations. Testing the PASS device is equally important because it serves as a safety feature that alerts other firefighters if one descends into a situation where they may be immobilized or have lost consciousness. If a PASS device is not functioning correctly, it could compromise the safety of the firefighter and create additional risks for their team during an emergency. Verifying that both the air supply and the PASS device are operational ensures that the firefighter can safely rely on their equipment while performing their duties. In summary, this choice focuses on critical operational safety checks that directly impact a firefighter's ability to perform effectively and safely in hazardous environments.
