What must be tested on SCBA equipment as part of the pre-use checks?

• A. Tank fuel levels
• B. Low pressure alarm
• C. Braking system
• D. Visual appearance

Answer: (B)

Testing the low-pressure alarm on SCBA (Self-Contained Breathing Apparatus) equipment is crucial as part of pre-use checks. The low-pressure alarm is a safety feature designed to alert the user when the air supply in the tank is approaching a dangerous level. This is important for ensuring that firefighters are aware of their remaining air supply while operating in environments where visibility and communication could be compromised. If the alarm is malfunctioning, it could lead to a situation where a firefighter may run out of air without warning, potentially resulting in a life-threatening situation. While checking tank fuel levels and visual appearance are also important components of ensuring SCBA readiness, they do not provide the immediate feedback regarding air supply that the low-pressure alarm does. The braking system is unrelated to the SCBA and is typically relevant to operational vehicles rather than personal protective equipment, making it irrelevant for this context. Thus, prioritizing the functionality of the low-pressure alarm directly supports the safety and operational effectiveness of firefighters in the field.
