Respiratory Protection Program
When does WorkSafeBC require a Respiratory Protection Program versus simple PPE use?
WorkSafeBC requires a written RPP whenever respirators are used as a control measure for airborne hazards to keep exposure within safe limits, i.e., when measured or predicted exposure could exceed an occupational exposure limit without respiratory protection, or when respirators are the only practicable means of hazard control.
What standards must a BC Respiratory Protection Program reference to be considered compliant?
A compliant BC RPP must reference WorkSafeBC OHS Regulation Part 5 (Chemical and Biological Substances, especially 5.48–5.59) and Part 8 (Personal Protective Clothing and Equipment), and CSA Z94.4 'Selection, use, and care of respirators.' Additional references include WorkSafeBC exposure limits and ACGIH TLVs for hazard assessment.
How should APF be used to select respirators in the RPP?
The RPP must use APF-based selection: determine exposure level (C_ambient) and acceptable exposure limit (C_OEL), calculate required protection factor (PF_req = C_ambient / C_OEL), then select a respirator with APF ≥ PF_req. For example, welding fume with Mn at 1.5 mg/m³ and OEL 0.1 mg/m³ requires PF_req = 15, so a half-mask APR (APF 10) is insufficient; a full-face APR or PAPR with APF ≥ 25–50 is needed.
A Respiratory Protection Program (RPP) is a formal, written employer-administered program governing the selection, use, care, and management of respirators to control worker exposure to airborne contaminants within acceptable limits. In British Columbia, it must comply with WorkSafeBC OHS Regulation Part 5 and Part 8, and CSA Z94.4, and is required whenever respirators are used to control breathing hazards.
On a manufacturing or shop floor, an RPP translates into concrete controls: hazard assessment via air monitoring to identify exposures exceeding limits; respirator selection based on contaminant type and required Assigned Protection Factor (APF); annual fit testing and medical assessments for users; training on donning, seal checks, and limitations; and procedures for cleaning, inspection, and storage. Supervisors enforce clean-shaven policies for tight-fitting respirators and schedule change-out schedules for cartridges. The program is administered by a designated program administrator and reviewed annually to ensure effectiveness.
Respirators are handed out without a formal written RPP covering hazard assessment, selection, fit testing, training, maintenance, and program evaluation, violating CSA Z94.4 and WorkSafeBC requirements.
Workers use tight-fitting respirators without fit testing or with facial hair interfering with the seal, leading to actual protection far below the APF and increased risk of occupational disease.
Respirators are stored dirty or damaged, cartridges used beyond service life, and cleaning/disinfection inconsistent, compromising protection and violating RPP maintenance procedures.
