About this session
Heat stress develops when the body gains heat faster than it can safely release it.
Outdoor weather matters, but occupational heat can also come from ovens, furnaces, steam, hot machinery, enclosed spaces, vehicles, kitchens, roofs, warehouses and physically demanding work performed in protective clothing.
Participants learn to assess the whole heat load rather than relying on air temperature alone.
Humidity can reduce evaporative cooling, radiant heat can add substantial thermal load, low air movement can limit heat loss, hard physical work generates metabolic heat and required PPE or clothing may trap heat close to the body.
The course then moves upstream into prevention. Shade, insulation, ventilation, cooling, mechanization, task scheduling, genuine recovery periods, workload changes, staffing, acclimatization and access to suitable fluids all have roles.
Hydration is important, but it is never presented as permission to continue excessive heat exposure.
Participants also learn to recognize worsening heat illness and respond appropriately.
Confusion, collapse, seizure, loss of consciousness or other major neurological change during heat exposure is treated as a medical emergency requiring immediate escalation and prompt cooling through the workplace emergency process.
Longer programs build a complete heat-management system covering assessment, monitoring, acclimatization, controls, supervision, emergency readiness and learning from changing conditions and heat events.
What your people take away
- Understand how environment, physical work and clothing or PPE combine to create heat stress
- Recognize why humidity, radiant heat, air movement and metabolic workload matter alongside temperature
- Apply stronger engineering, work-design, scheduling, recovery and cooling controls before relying on hydration alone
- Understand acclimatization and why new or returning workers may need a gradual increase in heat exposure
- Recognize early heat illness and the emergency signs that require immediate escalation and cooling
- Build heat-risk decisions into monitoring, staffing, supervision, emergency planning and management of change

What each length covers
30 minutes
30 Minutes — Key Points: Read the Whole Heat LoadA focused 30-minute session on three key points from Read the Whole Heat Load: look beyond the air temperature, add the heat created by the work and account for clothing and required PPE.
- Look beyond the air temperature
- Add the heat created by the work
- Account for clothing and required PPE
Covers 3 of 4 points in Read the Whole Heat Load.
60 minutes
60 Minutes — Heat Stress Management EssentialsA focused introduction to environmental heat, physical workload, clothing and PPE, stronger workplace controls and the warning signs of heat illness. Participants work through a representative hot-work scenario and identify what should change before someone becomes unwell.

- Module 2 — Control Heat Before Symptoms Start
- Module 3 — Recognize Heat Illness and Respond Early
- Module 4 — Build a Reliable Heat Management System
- Heat Source and Exposure Map
- Environment–Workload–PPE Exercise
- Hierarchy of Heat Controls Exercise
- Work / Recovery Scenario
- Hydration Access Review
- Acclimatization Planning Scenario
- Heat Monitoring Decision Exercise
- Heat Illness and Emergency Response Scenario
- 30-Day Heat Management Action Plan
- Live Q&A
Covers all 4 parts.
Also available as a 4-week or 8-week program, for change that lasts. Ask us about it.
What’s covered
Read the Whole Heat Load
Every length- Look beyond the air temperatureAir temperature is only one part of occupational heat exposure.
- Add the heat created by the workThe body produces heat during physical work.
- Account for clothing and required PPECoveralls, protective suits, respirators, gloves, helmets, body armor and other required equipment can reduce heat loss or increase the effort needed to perform a task.
- Recognize that heat tolerance changesHeat exposure can affect people differently and tolerance can change after time away from hot work, illness, reduced fitness for the task or other personal factors.
Control Heat Before Symptoms Start
90 minutes and longer- Reduce the heat at sourceWhere possible, heat is controlled before it reaches the worker.
- Design real recovery into the workRecovery needs to reduce heat load genuinely.
- Make hydration available without making it the whole planRegular access to suitable drinking fluids supports normal thermoregulation during hot work.
- Plan staffing, pace and timing around the heatHeat risk can increase when deadlines, staffing shortages, production peaks or service demand compress recovery and extend continuous exposure.
Recognize Heat Illness and Respond Early
3 hours and longer- Notice change before someone collapsesHeadache, dizziness, unusual fatigue, weakness, nausea, cramps, heavy sweating, reduced coordination or behavior that seems different from normal can signal that a worker is struggling with heat.
- Respond promptly to possible heat exhaustionWhen heat illness is suspected, participants learn the core response principles.
- Treat altered mental status as an emergencyConfusion, collapse, seizure, loss of consciousness or major behavior or coordination change during significant heat exposure can indicate a life-threatening emergency.
- Use buddy and supervisor checks to catch deteriorationHeat can impair judgment, meaning the person becoming unwell may not recognize how much their condition has changed.
Build a Reliable Heat Management System
Full day only- Build acclimatization into planningPeople who are new to hot work, returning after time away or encountering a sudden increase in heat may need a gradual increase in exposure with closer observation.
- Use monitoring to support decisionsWeather information, heat index, workplace measurements and tools such as WBGT can support heat-risk decisions when used appropriately.
- Make supervisor authority and stop-work routes clearA heat plan works only when somebody can act on changing conditions.
- Learn from heat events and changing conditionsNear misses, heat symptoms, failed cooling equipment, inaccessible water, unexpected hot weather, workload surges or repeated emergency responses can reveal weaknesses in the heat-management system.
