Checklist: Preventing cold stress

The following recommendations from The National Institute for Occupational Safety and Health (NIOSH) should be followed to help prevent cold stress.

Recommendations for employers

Employers should take the following steps to protect workers from cold stress:

• Schedule maintenance and repair jobs in cold areas for warmer months.
• Schedule cold jobs for the warmer part of the day.
• Reduce the physical demands of workers.
• Use relief workers or assign extra workers for long, demanding jobs.
• Provide warm liquids to workers.
• Provide warm areas for use during break periods.
• Monitor workers who are at risk of cold stress.
• Provide cold stress training that includes information about:
  • Worker risk.
  • Prevention.
  • Symptoms.
  • The importance of monitoring yourself and coworkers for symptoms.
  • Treatment.
  • Personal protective equipment (PPE).
   

Recommendations for workers

Workers should avoid exposure to extremely cold temperatures. When cold environments or temperatures 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 coworkers.
