Hand-Arm Vibration: Reducing HAVS Risk with Tool Selection and Exposure Control

Reduce hand-arm vibration risk by controlling exposure duration and tool characteristics.

WorkSafeBC lists vibration among recognized hazards and exposures, reinforcing it as an occupational health issue requiring control. HAVS prevention begins with task inventory: which jobs require high-vibration tools (grinders, breakers, drills) and how often.

Controls should prioritize substitution and engineering: lower-vibration tools, maintained tools (worn bearings and bits can increase vibration), automation or mechanical aids, and work redesign to reduce grip force and awkward posture. BCCSA emphasizes engineering controls as workplace changes that reduce exposure at source. Administrative controls often determine real exposure: rotate tasks, limit daily trigger time, schedule breaks, and avoid cold/wet conditions because cold impairs circulation and increases sensitivity.

Verification is practical: confirm maintenance schedules are followed, exposure limits are respected, and symptoms are reported and acted on. Treat symptom reporting as a leading indicator and reassess controls promptly.
