Heat is more than the weather forecast
Physical effort, humidity, radiant heat and some protective clothing can increase the heat burden. Equipment that traps heat or moisture can make recovery harder. Review the actual work conditions and the PPE being worn rather than assuming a mild air temperature means a low-risk task. Include workers who are new to hot work or returning after time away in the plan.
Make cooling part of the job
Provide drinking water and opportunities to recover in a cooler area. Adjust work demands, timing and recovery periods through the site’s heat plan where feasible. Build up exposure to hot work gradually under appropriate supervision. Do not simply remove required protection while the hazard is still present; identify safe areas and procedures for cooling and changing equipment.
Watch each other, not just the clock
Headache, nausea, dizziness and unusual weakness can be warning signs. Train workers to recognise symptoms, report them early and check on colleagues. Move a symptomatic worker to a cooler safe area, stay with them and seek medical guidance. Someone struggling in the heat should not be sent to rest alone and forgotten.
Know when it is an emergency
Confusion, slurred speech, seizures or collapse can signal a life-threatening heat emergency. Call emergency services immediately, begin cooling promptly in a safe area and stay with the worker. Do not force drinks on someone who is confused, unconscious or unable to swallow safely. Plan the emergency response before the hottest day arrives.
