What is the general sequence for donning PPE and SCBA before interior operation?

• A. Inspect PPE; don coat, pants, gloves, boots; put on helmet and hood; then don SCBA, attach facepiece; perform seal check and radio check.
• B. Don SCBA first; then coat, pants, gloves, boots; don helmet; skip checks.
• C. Put on helmet and hood before inspecting PPE.
• D. Don PPE after entering interior.

Answer: (A)

The basic idea is to ensure everything is functional and fitted correctly before you enter a hazardous space, and to have the breathing apparatus ready only after you’re properly dressed so the mask can seal and stay in place. Start with a gear inspection to catch any damage or wear, because preventing a fault inside a structure is essential. Then don the protective clothing—coat, pants, gloves, and boots—to establish your barrier against heat, smoke, and debris. The hood and helmet come next, since the hood provides neck and head protection and should fit under the helmet without being displaced when you move. Having these layers on before the breathing apparatus helps ensure the facepiece can seal properly and won’t be disturbed by other garments. Don the SCBA and attach the facepiece, then perform a seal check to confirm there’s no air leakage and you’re getting proper respiratory protection. Finally, running a radio check ensures you can communicate with your team. This sequence minimizes the risk of gear damage, ensures proper fit, and confirms readiness before interior operation.
