Toolbox Talk:

Fit Matters — Ensure a Proper Seal on Your Respirator

June 25, 2025

A respirator is only as good as its seal. If it doesn’t fit your face properly, airborne contaminants can leak in — even if you’re wearing the right mask.

Why It Matters:

A poor fit means false protection. Particles, dust, or vapors can sneak through gaps and go straight into your lungs. OSHA requires fit testing for tight-fitting respirators — and your daily seal check is just as important.

Key Points:

  • Tight-fitting respirators must pass an annual fit test — no exceptions.
  • Perform a user seal check every time you put one on. Cover the mask and inhale or exhale slightly to check for leaks.
  • Facial hair, glasses, and even sweat can break the seal — keep the contact surface clean and clear.
  • Replace worn or stretched straps — they can compromise the fit over time.
  • Don’t swap respirators — what fits one person may not fit another.

✅ If it doesn’t seal, it doesn’t protect.

Ask the Crew:

  • Have we done our fit testing this year?
  • Did everyone check their seal before starting work?
