Noise in BC Workplaces: Building a Hearing Conservation Program Under OHSR Part 7
Implement a hearing conservation program based on measurement and control.
Noise-induced hearing loss is permanent and preventable. CCOHS states that if monitoring shows exposures at or above 85 dBA, a hearing conservation program should be developed and implemented, describing program elements aligned with CSA hearing-loss prevention standards. WorkSafeBC identifies noise as a recognized hazard and embeds expectations for controlling physical sources within the employer’s general duties.
A strong program starts with measurement and mapping: identify noise sources and exposure patterns by job and task. Then prioritize engineering controls (enclosures, isolation, maintenance, substitution). Administrative controls can support but should not replace feasible engineered reductions. BCCSA’s guidance on engineering controls reinforces that physical changes (barriers, enclosures, maintenance) are typically the stronger prevention lever.
Hearing protection is a residual control: select devices appropriate to the environment, train workers to use them correctly, and verify use during normal operations. Use program data (observations, incident/near-miss signals, annual hearing test) to review and improve controls over time.
