After donning SCBA and facepiece, which checks should be performed?

• A. Seal check and radio check
• B. Only seal check
• C. Only radio check
• D. No checks

Answer: (A)

After you don the SCBA and facepiece, you perform two checks to start safely: a seal check and a radio check. The seal check verifies there are no leaks around the facepiece and that air is delivering properly to your lungs. You test this with positive pressure by inflating the facepiece against your face and feeling for leaks, and with negative pressure by slightly inhaling to ensure the facepiece seals without tugging away from the face. If you detect any air leaking at the seal, readjust the mask until the seal holds.

The radio check confirms your communication device is working, on the right channel, and capable of transmitting and receiving. Clear, reliable communication is vital for coordinating movements, reporting hazards, and requesting assistance in the challenging and dangerous environment you’re operating in.

Together, these checks ensure you’re getting breathable air without leaks and that you can stay in touch with your team and command. Skipping either check could mean breathing contaminated air or losing critical situational updates.
