A firefighter's low-air alarm sounds while working inside. The correct action is to
- Finish the task first and then walk out alone
- Skip-breathe and stay to help the rest of the crew
- Switch the alarm off and watch the gauge instead
- Leave the hazard area at once with the crew
Show the answer
D. Leave the hazard area at once with the crew
The low-air alarm means only the reserve is left, so the firefighter and partner exit immediately. Nobody leaves alone, and controlled breathing is an emergency technique for someone who is trapped, not a way to stay and work.

The protective hood is worn mainly to protect the
- Ears, neck and face areas the facepiece misses
- Eyes from flying debris during overhaul work
- Top of the head from falling objects and impact
- Lungs from smoke before the SCBA is put on
Show the answer
A. Ears, neck and face areas the facepiece misses
The hood covers the skin left exposed between the helmet, facepiece and coat collar. Impact protection comes from the helmet and respiratory protection only from the SCBA.

The main purpose of a personnel accountability system is to
- Record the hours each member works for the payroll
- Track where each member is and what they are doing
- Decide which company gets the next assignment on scene
- Keep the news media and bystanders out of the fireground
Show the answer
B. Track where each member is and what they are doing
Accountability systems (tags, passports, electronic tracking) let command know who is on scene, where they are and what they are doing, so a missing member is noticed quickly. Assigning companies is a command function that uses this information.
