Why Fit Testing Matters

A Respirator Only Protects When It Seals

A small gap lets contaminants in. Common hazards in construction:

  • Silica from cutting, grinding and drilling concrete
  • Drywall, wood and demolition dust
  • Asbestos and lead in renovation
  • Paint, coating and solvent vapours

Crews and subcontractors change often. We keep every worker current.

Frequently Asked Questions

Common questions from construction companies about on-site respirator fit testing.

When is respirator fit testing required in BC?
arrow_forward_ios

Under WorkSafeBC's Occupational Health and Safety Regulation, a worker must pass a fit test before being issued a tight-fitting respirator, using CSA Standard Z94.4 procedures. Section 8.40 of that Regulation then requires retesting at least once a year. Workers should also be retested when they change respirator model or size, or have facial changes such as significant weight change or dental work.

What respirators can you test?
arrow_forward_ios

We provide qualitative fit testing for N95 disposable respirators and suitable half-face reusable respirators, from 5 people per visit. For larger groups we also provide quantitative fit testing, which measures a numeric fit factor and covers full-face respirators and tight-fitting PAPR facepieces. If only a handful of your workers use full-face respirators, smaller groups can be accommodated for an additional fee — tell us your numbers and we will quote it.

How should workers prepare?
arrow_forward_ios

Nothing can come between the respirator and the skin where it seals, so workers must be clean-shaven along the seal line, with no hair, jewellery or eyeglass arms under the edge. They should bring the exact respirator make, model, and size they use, plus any gear they wear with it, such as safety glasses or a hard hat.

Can you fit test at an active jobsite?
arrow_forward_ios

Yes. We just need a small space out of the wind and away from heavy dust, such as a site trailer or office. We will confirm the setup with you ahead of time.

Can you test new hires and subcontractors?
arrow_forward_ios

Yes. We can test new hires and subcontractor crews as they join your project, and add their results to your records.
