Heat Stress

Your body cools itself by sweating — until it can't keep up. Heat illness escalates fast: cramps, exhaustion, then heat stroke, which kills. New crew members in their first week of hot work are at the highest risk.

1
Water. Rest. Shade.

Drink a cup of water every 15–20 minutes — before you feel thirsty. Take breaks in shade or AC. Dark urine means you're already behind.

2
Know the warning signs

Heavy sweating, headache, dizziness, nausea = heat exhaustion. Get them to shade, loosen clothing, cool with water. Confusion, hot dry skin, passing out = heat STROKE — call 911 and cool them aggressively. Never leave them alone.

3
Acclimatize new workers

It takes 1–2 weeks for the body to adapt to heat. New hires and returning workers should ramp up: 20% exposure day one, add 20% each day.

4
Adjust the work, not just the worker

Schedule heavy tasks for morning, rotate crews, use buddy systems above 90°F. At 100°F+, postpone non-essential heavy work.
