Workers who are exposed to extreme cold or work in cold environments may be at risk of cold stress. Extreme cold weather is a dangerous situation that can bring on health emergencies in susceptible people, such as those without shelter, outdoor workers, and those who work in an area that is poorly insulated or without heat.

What constitutes cold stress and its effects can vary across different areas of the country. In regions relatively unaccustomed to winter weather, near freezing temperatures are considered factors for cold stress. Whenever temperatures drop decidedly below normal and as wind speed increases, heat can more rapidly leave your body. These weather-related conditions may lead to serious health problems.

When cold environments cannot be avoided, workers should follow these recommendations to protect themselves from cold stress:

  • Wear appropriate clothing.
    • Wear several layers of loose clothing. Layering provides better insulation.
    • Tight clothing reduces blood circulation. Warm blood needs to be circulated to the extremities.
    • When choosing clothing, be aware that some clothing may restrict movement resulting in a hazardous situation.
  • Make sure to protect the ears, face, hands and feet in extremely cold weather.
    • Boots should be waterproof and insulated.
    • Wear a hat; it will keep your whole body warmer. (Hats reduce the amount of body heat that escapes from your head.)
  • Move into warm locations during work breaks; limit the amount of time outside on extremely cold days.
  • Carry cold weather gear, such as extra socks, gloves, hats, jacket, blankets, a change of clothes and a thermos of hot liquid.
  • Include a thermometer and chemical hot packs in your first aid kit.
  • Avoid touching cold metal surfaces with bare skin.
  • Monitor your physical condition and that of your coworkers.
