Which of the following statements about facial hair and seal areas is correct?

• A. Beards or facial hair cannot be in the seal area
• B. Beards or facial hair is allowable if neat and trim
• C. Eyeglasses with side frames passing through the seal area are allowable
• D. Firefighters do not need to maintain a tight seal as the mask maintains positive pressure

Answer: (A)

Beards or facial hair cannot be in the seal area. The seal of a facepiece must contact bare skin to form an airtight barrier against contaminants. Hair in that zone creates gaps and channels for air to leak, which defeats the protection the respirator is supposed to provide. Even neat and trimmed facial hair can interfere with the seal, so it’s not allowed. Eyeglasses with side frames that pass through the seal area would also disrupt the seal and are not permitted. Relying on positive pressure to compensate for a poor seal is unsafe because a compromised seal can still allow contaminants to enter. In practice, stay clean-shaven in the seal area and perform a seal check before use.
