In light of recent frigid temperatures, the US-American Occupational Safety and
Health Administration is reminding workers and employers, whose work is
concentrated outside, to take the necessary precautions to prevent cold-related
injuries and illnesses.

When the body is unable to warm itself, serious coldrelated illnesses and
injuries may occur, and permanent tissue damage and death may result.
Coldrelated illnesses can slowly overcome a person who has been chilled by low
temperatures, brisk winds, or wet clothing.

OSHA's "Cold Stress Pocket Card" provides recommendations on protecting workers
in cold environments. For example, take frequent short breaks in warm dry
shelters to allow the body to warm up.
