Machine Safeguarding and OHSR Part 12: Designing Guards People Will Actually Use
Prevent contact with moving parts by implementing effective, usable safeguarding.
WorkSafeBC describes safeguarding measures (barrier guards, devices, shields) intended to protect workers from machinery hazards. OHSR Part 12 defines “guard” and supports the expectation that workers are prevented from accessing dangerous moving parts.
Safeguarding fails when it conflicts with real work (setup, jam clearing, cleaning). Design safeguards around these tasks using engineered solutions (interlocks, remote clearing tools, enclosure) and ensure lockout is the prerequisite when exposure is unavoidable.
Treat guard integrity as a critical control with lifecycle management: inspections, maintenance, modification control, and supervisor verification.

Identify non-routine tasks that create exposure; redesign safeguarding to prevent bypass; verify guard function and lockout discipline through inspections.
