Key Hazards
- Heat exhaustion or heat stroke
- Dehydration from sweating and physical work
- Reduced focus, slower reaction time, and poor decision-making
- Heat exposure increased by PPE, direct sun, humidity, or hot surfaces
- Workers ignoring early symptoms to finish the task
- New or returning workers not acclimatized to hot conditions
2–3 Minute Talk Script
Heat stress can affect workers quickly, especially during outdoor work, heavy labor, utility work, construction, landscaping, road work, and jobs near hot equipment or pavement.
Heat risk is not based on temperature alone. Humidity, direct sun, low air movement, physical workload, PPE, reflected heat, and lack of acclimatization can all increase the danger.
Workers should drink water regularly before they feel thirsty. Waiting until thirst develops is not a reliable way to manage hydration during hot work.
Rest breaks, shade, cooling areas, and adjusted work pace are important controls. During high heat, crews may need to rotate tasks or schedule harder work during cooler parts of the day.
Early symptoms of heat illness can include headache, dizziness, weakness, heavy sweating, cramps, nausea, irritability, confusion, or unusual behavior.
Heat stroke is a medical emergency. Confusion, collapse, hot skin, or a worker who stops sweating during severe heat exposure should be treated as urgent.
Coworkers should watch each other because a person experiencing heat illness may not recognize how serious their condition is.
Heat stress prevention works best when it is planned before the shift starts. Water, shade, breaks, communication, and early reporting should be treated as part of the job.
Safety Reminders
- Drink water regularly throughout the shift.
- Use shade or cool areas for recovery breaks.
- Adjust work pace during high heat and humidity.
- Watch for headache, dizziness, cramps, nausea, or confusion.
- Check on coworkers during hot-weather work.
- Give new or returning workers time to acclimatize.
- Report heat symptoms early instead of pushing through.
Ask the Crew
- How hot and humid are conditions expected to be today?
- Where are water, shade, and cooling areas available?
- Does the work pace need to be adjusted?
- Are any workers new, returning, or not acclimatized?
- How will the crew respond if someone shows heat illness symptoms?
