• SCBA (Self-Contained Breathing Apparatus) warning systems on firefighting gear • The meaning of a continuous low-air alarm versus a brief test alarm • What condition the bell is designed to alert the wearer to

💭 Think About

• Ask yourself: When would you need a loud, unmistakable continuous bell while wearing an SCBA—during normal operation or when something is wrong? • Consider which of the listed problems would be most critical to warn you about immediately, even if you couldn’t see your gauges. • Think about how the unit tells you it’s working properly—would that normally be a short check signal or a constant alarm?

✅ Before You Answer

• Verify what a continuous ringing bell on SCBA typically indicates (especially regarding air pressure level in the bottle). • Check which option describes a condition that would require you to stop and correct the problem or change equipment right away. • Eliminate any choices that describe issues which would normally be found by fit checks (like mask seal) rather than by a continuous bell alarm.
