Stubble = leaks.
Here's why 👇
A beard hair is around 100 microns thick.
Silica dust is under 10 microns.
Welding fume is mostly under 1 micron.
Even a day or two of growth lifts your respirator's seal off your skin, and contaminated air goes around the filter instead of through it. 😷
📋 AS/NZS 1715 says tight-fitting respirators must seal against bare skin.
That means clean-shaven for your fit test AND every shift you wear one.
✅ Shave before your fit test
✅ Shave before every shift
✅ Can't stay clean-shaven? Ask us about PAPRs (powered air-purifying respirators, no face seal needed)
✅ Retest every year, or when your face, weight or mask changes
