What is the correct donning sequence for a firefighter's breathing apparatus (SCBA) in a drill?

• A. Buckle harness, put on mask, connect air supply, check face seal
• B. Put on mask, buckle harness, connect air supply, perform a quick check of face seal, and enter with air supply on
• C. Connect air supply, put on mask, buckle harness, enter
• D. Put on mask, enter space, then buckle harness

Answer: (B)

The main idea here is to ensure you’re physically prepared and breathing-ready before entering a hazardous area. Put the mask on first so you can test the face seal right away, ensuring there are no leaks around the mask itself. Next, secure the harness to stabilize and support the SCBA weight, which makes handling and movement safer and more comfortable. Then connect the air supply so you actually have breathable air as you prepare to enter. After the air is connected, do a quick face-seal check with the air on to confirm the seal remains airtight under positive pressure. Finally, enter with the air supply active, ready to continue breathing as you work. This sequence minimizes risk by validating the seal and air supply outside or at the entry point before committing to the hazardous space.
