1. Why does chemical protective clothing increase heat stress?

Answer: It stops sweat from evaporating. Impermeable clothing traps heat and moisture, blocking evaporative cooling.

2. Which sign points to heat stroke rather than heat exhaustion?

Answer: Confusion or slurred speech. Confusion, collapse or seizures signal heat stroke, a medical emergency.

3. What should you do for suspected heat stroke?

Answer: Call 911 and cool the person immediately. Heat stroke can kill. Call for emergency help and start rapid cooling.

4. Who is at highest risk of heat illness on a new job?

Answer: New or returning workers who are not acclimatized. Acclimatization takes one to two weeks of gradually increasing exposure.

5. A common hydration recommendation during hot work is:

Answer: About one cup every 15 to 20 minutes. Small amounts often replace fluids better than large amounts occasionally.

6. Heart rate at the start of rest is above 110 bpm. A common guideline is to:

Answer: Shorten the next work cycle by one third. NIOSH/OSHA/USCG/EPA guidance shortens the next work cycle by a third and keeps the rest period the same.

7. Which control helps workers in Level A or B stay cool?

Answer: Cooling vests. Cooling vests, shaded rest areas and scheduling heavy work for cooler hours all help.

8. The buddy system helps with heat stress because:

Answer: Partners can spot early warning signs in each other. People with heat illness often don't recognize their own symptoms.
