  • Burns (from contact with hot surfaces or steam)

Other Risks

If you are 65 years or older, or are taking certain medications, you also have a greater risk of heat-related hazards.

Proper Clothing

You can minimize heat stress by wearing appropriate clothing. When working in hot environments, select clothing that is:

Safe Work Practices

You can minimize heat stresses by following these general safe work practices:

  • If you are not used to hot work conditions, don’t attempt to do too much too fast; gradually build up to heavy work.
  • Use the coolest part of the day for the most intense work.
  • Take more breaks throughout the work day and develop an hourly work-rest cycle.
  • Use areas of shade or cool whenever possible and especially when taking breaks.
  • Monitor weather conditions prior to work and as they change throughout the day.

Adequate Hydration

Minimize heat stress by:

  • Drinking water frequently
  • Avoiding drinks with caffeine, alcohol and sugar
  • Choosing liquids with electrolytes

Monitor Yourself and Others

Minimize heat stress by:

  • Monitoring yourself and your co-workers for signs and symptoms of heat stress illness.
  • Informing your supervisor of existing medical conditions that may increase your risks when working in hot environments.
  • Being extra cautious when you or your co-workers have existing medical conditions or are taking medications that may increase the risks of working in hot environments.
