About this session
Heat stress develops when the body gains or produces more heat than it can safely release. Outdoor temperature is only part of the picture.
Humidity, direct sun, hot surfaces, radiant heat, physical effort, protective clothing, poor air movement and the length of the exposure can all increase the heat load on a worker.
This session helps participants understand occupational heat as a work-design and exposure-control issue rather than simply a reminder to drink water.
They learn how engineering controls, shade, cooling, work scheduling, recovery periods, acclimatization, staffing, environmental monitoring and appropriate clothing or PPE can work together to reduce risk.
Participants also learn to recognize changes that may indicate heat strain is becoming serious and why altered mental status, collapse or other signs of severe heat illness require an immediate emergency response.
The session keeps medical diagnosis with appropriate professionals while giving workers and supervisors a clear framework for prevention, early action and escalation.
What your people take away
- Understand how environmental heat, physical workload, clothing and recovery combine to create heat strain
- Recognize early changes that may signal increasing heat stress or heat illness
- Apply the hierarchy of controls to reduce heat exposure before relying on individual coping strategies
- Plan work, rest, shade, cooling and hydration around the actual heat load
- Understand the role of acclimatization when people begin or return to hot work
- Build stronger communication, monitoring and emergency-response arrangements for hot conditions

What’s covered
Understand How Heat Stress Builds
Every length- Look beyond air temperatureHeat exposure depends on more than the number shown on a weather app or wall thermometer.
- Add the heat created by the workPhysical work produces metabolic heat inside the body.
- Understand the effect of clothing & PPEProtective clothing, coveralls, impermeable garments and some forms of PPE can trap heat and reduce evaporation.
- Recognize cumulative heat loadHeat strain can build across a shift when exposure continues faster than the body can recover.
Recognize Heat Strain & Act Early
90 minutes and longer- Notice changes before the situation becomes severeIncreasing fatigue, headache, dizziness, nausea, weakness, unusual irritability, heavy sweating, cramping or reduced coordination can signal that a worker is struggling with the heat.
- Watch for changes in thinking & behaviorConfusion, unusual behavior, disorientation, loss of coordination, collapse or a significant change in mental status can indicate a medical emergency.
- Use coworkers & supervisors as an early-warning networkHeat strain can affect judgment, which means the person becoming ill may not recognize the seriousness of their own condition.
- Know when self-management is no longer enoughMinor discomfort and severe heat illness are not the same problem.
Control Heat Before Relying on the Worker
3 hours and longer- Reduce the heat at the sourceWhere possible, workplaces can reduce radiant or process heat through insulation, shielding, ventilation, cooling, enclosure, equipment changes or changes to the process itself.
- Change when & how hot work is doneScheduling demanding tasks for cooler periods, reducing exposure duration, rotating appropriately different work and planning recovery can lower total heat burden.
- Provide effective shade, cooling & recoveryRecovery is more effective when rest areas genuinely reduce heat load.
- Support hydration without making it the whole planWorkers need practical access to suitable drinking water and realistic opportunities to drink during hot work.
Build Heat Safety Into the Work System
Full day only- Plan for acclimatizationPeople who are new to hot work, returning after time away or moving into substantially hotter conditions may need progressive exposure while their bodies adapt.
- Monitor conditions that change the riskHeat conditions can change through the day as temperature, humidity, sun exposure, radiant heat, workload and protective clothing change.
- Build clear triggers for changing the workA heat plan is stronger when supervisors and employees know what happens as conditions become more demanding.
- Prepare for a heat emergencyThe workplace needs a clear response if a worker develops signs of severe heat illness.
