When should you check your SCBA gauge to see how much air you have left?

• A. When the assigned area is reached.
• B. Before entering any hazard area.
• C. After the incident is over.
• D. Only after you hear a low-air alarm.

Answer: (A)

The main idea is air management and verifying your air supply at the moment you take on a defined task area. You check your SCBA gauge when you reach your assigned area so you know exactly how much breathable air you have left for the work you’re about to perform and for a safe exit. This timing lets you plan based on the specific tasks in that area and coordinate with your buddy and supervisor about remaining air and bailout options if needed. Waiting for a low-air alarm is unsafe because you’ve waited until air is already running low, and checking after the incident is over doesn’t help you stay safe during the operation. While you should perform pre-entry checks as part of overall readiness, the question emphasizes the point of assignment, where you confirm you have enough air for the tasks ahead.
