Scout's Toolbox Talks

A respirator is only effective if it fits properly. Without a tight seal, contaminated air can leak in and expose you to serious harm.

Why It Matters:

Even a small gap can make your respirator useless. Facial hair, incorrect positioning, or damaged straps all compromise protection — putting your lungs and life at risk.

Key Points:

• Perform a user seal check every time you put on a respirator.
• A proper seal check includes a positive pressure test (exhale gently and feel for leaks) and a negative pressure test (inhale slightly to check for tightness).
• You must be clean-shaven where the respirator seals to your face — OSHA requires it.
• Damaged or worn respirators must be replaced immediately.
• Fit testing must be done annually or if facial features change significantly (e.g., weight loss, dental work, facial injuries).

✅ A respirator without a seal is like a parachute with a tear.

Ask the Crew:

• Have you seal-checked your respirator today?
• Is anyone wearing a mask over facial hair? Should we stop and correct it?
