PPE Basics Awareness

Yes. Under all Canadian provincial OHS legislation - including Alberta OHS Code Part 18, BC OHS Regulation Part 8, and the Ontario Occupational Health and Safety Act - employers must provide required PPE at no cost to workers. Employers must also conduct a hazard assessment to determine what PPE is needed, ensure it meets the applicable CSA standard for the specific hazard, and train workers on correct use before they start work. Workers cannot be required to purchase their own protective equipment, with narrow exceptions for industry-standard items like safety footwear in some jurisdictions.

Yes. Canadian OHS legislation requires employers to apply the hierarchy of controls - meaning PPE is legally the last resort, not the first response. In Alberta, OHS Code Section 9 requires a written hazard assessment and safe work procedures addressing higher-level controls first. In BC, the OHS Regulation requires elimination of hazards at the source to the extent practicable. PPE is a required supplement to engineering and administrative controls, not a substitute for them. An employer who skips engineering controls and goes straight to issuing PPE may still be in violation even if the PPE itself is correct.

No. An N95 filtering facepiece filters 95% of airborne particles but provides zero protection against organic vapours, gases, or oxygen-deficient atmospheres. A worker wearing an N95 in a space with solvent fumes, hydrogen sulfide, carbon monoxide, or any IDLH atmosphere is unprotected. Chemical vapour exposures require a half-face or full-face elastomeric respirator fitted with the correct cartridge type - for example, an organic vapour (OV) cartridge for solvents or an acid gas cartridge for chlorine. Respirators used in Canadian workplaces must meet CSA Z94.4 requirements, and employers must conduct fit testing for all tight-fitting respirators.

A hard hat must be replaced immediately after any significant impact from a falling object - even if no visible damage is present, because the polymer shell absorbs energy in a way that permanently reduces protection for future impacts. Additionally, signs of UV degradation (white chalky surface, flaking, or brittleness when lightly flexed) require immediate replacement. Most manufacturers specify a shell service life of 5 to 10 years and a suspension replacement interval of 2 to 5 years; the manufacture date is typically stamped inside the crown. Alberta OHS Code Part 18 Section 233 and BC OHS Regulation Section 8.8 both require PPE to be maintained in good working condition and replaced when damaged or defective.

Yes - and it is a recognized compliance issue. Safety glasses with temple arms extend across the cheek area where a half-face respirator must seal against the skin; the temple arm breaks the face seal and allows unfiltered air to bypass the cartridge on every breath. The correct solution is to use safety goggles (no temple arms) with a half-face respirator, or to upgrade to a full-face respirator that integrates eye and respiratory protection in a single sealed unit. Research has found that temple-arm frames can reduce respirator fit factor scores by 20 to 40 percent. Some jurisdictions now require that fit testing be conducted while the worker wears the full PPE ensemble they will use on the job, not the respirator alone.
