Why This Matters
Heat-related illness kills dozens of workers annually; construction is the highest-risk industry.
Types of Heat Illness
- Heat rash
- Heat cramps
- Heat exhaustion: heavy sweating, nausea, dizziness
- Heat stroke: hot dry skin, confusion, emergency
Risk Factors
- High temperature and humidity
- Direct sun exposure
- Heavy physical work
- Dark or heavy clothing
- Lack of acclimatization
- Dehydration
Water, Rest, Shade
- Drink water every 15-20 minutes (don't wait until thirsty)
- Take breaks in shade
- Use cooling vests or towels
Acclimatization
New and returning workers need gradual exposure over 7-14 days; most deaths occur in the first few days on the job.
Recognizing & Responding
- Heat exhaustion: move to shade, cool down, hydrate
- Heat stroke: call 911 immediately, cool aggressively (life-threatening)
Buddy System
Watch each other for symptoms; never leave someone alone who shows signs of heat illness.
