Ensuring a Secure Fit: How to Check Your Protective Mask

Fit Check Steps

1. Don properly: Cover nose, mouth, chin; no edge gaps.
2. Pinch nose bridge: Mold metal strip to nose to prevent top leaks.
3. Seal check: Cup mask, exhale forcefully. Air escaping = adjust fit.
4. Check for gaps: Look at cheeks, chin, nose sides while exhaling. Tighten loops/headbands if needed.
5. Breathing test: Inhale/exhale; should feel comfortable, no significant resistance.
6. Head movement: Turn side-to-side, up/down; mask should stay secure.
7. Facial hair: Beard/mustache may prevent seal; use mask designed for facial hair or consult professional.

Key Point

Mask effectiveness depends on proper fit. Seek guidance from healthcare or occupational safety specialist if fit issues persist.
