Respiratory protection

Select for the hazard, never by appearance

Full mask guide

Possible hazards

  • task-specific dust or products to confirm
hazard assessment first

Priority controls

  • Eliminate or reduce dust/vapour at the source before relying on a respirator.
  • Use appropriate wet methods, HEPA capture, local exhaust and isolation.
  • Read the SDS and exact product instructions.

What is not sufficient

  • Choosing a respirator by appearance or colour is not a selection method.

Stop if

  • Stop if the contaminant is unknown, air is inadequate, a seal is impossible or symptoms occur.

Final selection depends on contaminant, concentration, SDS, fit and the applicable program. An air-purifying respirator does not supply oxygen.

Yellow phase — complex project

Complex interior fit-out

Yellow describes technical complexity, not legal permission. Verify permits, inspections and trade requirements in your province, territory and municipality before starting.

Important limit

This guide helps prepare and oversee the project. Required plans, permits, inspections, manufacturer instructions and professionals prevail.
