Heat Stress in BC: Implementing OHSR Part 7 With Practical Work-Rest and Hydration

Prevent heat illness through assessment, water, work-rest cycles, and emergency response readiness.

Manufacturing Safety Alliance of BC’s heat stress factsheet describes heat illness progression and prevention through assessing work activities and implementing controls. WorkSafeBC recognizes heat stress as a hazard and expects employers to identify and control such risks under general duties.

Implement trigger-based controls: modify schedules, increase rest breaks, provide shade/cooling areas, ensure accessible cool drinking water, and use buddy observation for early symptoms. Manufacturing Safety Alliance of BC warns heat events increase risk, thus reinforcing the need for seasonal planning and work modifications.

Train crews and supervisors on symptom recognition and escalation response. Document daily heat controls and any heat-related incidents and corrective actions as due diligence evidence.

• Actionable takeaways

  Define heat triggers and escalation controls; provide water/shade and schedule changes; train supervisors to stop work and initiate response when symptoms appear.
