Study Notes
Physical Hazards (Cold Stress)
- Frostbite occurs when skin tissues freeze.
- Theoretically, the freezing point of skin is around 30°F (1°C).
- Wind velocity increases heat loss, causing frostbite to occur more rapidly.
- Air movement is more crucial in cold environments than in hot ones.
- Wind and temperature combine to produce windchill.
- Extremes of temperature (thermal stress) impact the amount and quality of work people can do.
