Cold Stress
If the worker is exposed to an environment so cold that the body cannot maintain adequate deep core temperature, hypothermia, which can also be life-threatening, may result.
Extremely low temperatures can cause potential life-threatening symptoms.
Symptoms brought on by cold stress include:
- Shivering;
- Clouded consciousness;
- Pain in the extremities;
- Dilated pupils;
- Reduced grip strength and coordination; and/or
- Possibly ventricular fibrillation.
Low temperature conditions may be caused by:
- Winter cold;
- High altitudes;
- Refrigerated surfaces; or
- Cryogenic lines and equipment.
These can result in muscle strain as well as cold "burns," frostbite, and hypothermia.
