What PPE and precautions are recommended for wildfire smoke exposure?

• A. Respiratory protection such as an N95 or P100, eye protection, protective clothing, minimize outdoor exposure, monitor symptoms, and seek medical care if symptoms persist.
• B. No protection is needed unless exposure is prolonged.
• C. Only wear a surgical mask in light smoke.
• D. SCBA should be worn by all responders at all times.

Answer: (C)

Wildfire smoke delivers tiny particulate matter that can irritate the airways and lungs, so protection focuses on filtering the air you breathe and reducing exposure. A properly fitted respirator such as an N95 or P100 helps remove many of the fine particles (PM2.5) that smoke carries. Eye protection helps prevent irritation from smoke contacting the eyes, and protective clothing can reduce skin irritation from smoke and soot. In addition, limiting outdoor time when smoke is thick and staying indoors with filtered air improves overall protection. If symptoms like coughing, shortness of breath, chest tightness, or wheezing persist or worsen, seek medical care promptly.

Surgical masks do not reliably filter fine smoke particles and thus provide insufficient protection. Wearing a self-contained breathing apparatus at all times isn’t practical for typical public exposure and is reserved for specific, trained responders in high-risk situations.
