Heat Safety Risks: High Temperatures and Heat-Related Illnesses

Heat Safety Risks: High Temperatures and Heat-Related Illnesses

Summer months are a great time for enjoying the outdoors with family and friends. But, it’s important to keep in mind that hot weather can be especially dangerous if proper safety precautions aren’t considered, particularly on an outdoor jobsite.

According to OSHA, working in hot weather and the direct sun increases the risk of heat-related illnesses in exposed workers, such as heat stress and heat exhaustion. “Every year, thousands of workers become sick from occupational heat exposure, and some are fatally injured.” Winter months alike, employers have a responsibility to take precautions for workers to have a place of employment free of hazards.

Heat-related illnesses and fatalities are preventable, but it’s important to identify the signs and react quickly and appropriately when they occur.

The main cause of a heat-related illness is your body’s inability to cool itself. While understanding the cause, it is also important to know that heat exhaustion is the precursor to heatstroke and is a direct result of the body overheating.

To protect workers from instances caused by high temperatures, it is essential to be educated on the causes, signs and treatment of heat-related illnesses. Keep in mind, when heat exhaustion is not addressed, heat stroke can follow.

Prevent heat-related illnesses by:

  • Drinking water frequently
  • Wearing light-colored, light-weight, loose-fitting, breathable clothing
  • Wearing safety glasses, sunscreen and brimmed hard hats with adequate UV protection
  • Scheduling more difficult, strenuous activity for cooler times of day
  • Taking frequent breaks in shaded, cooler areas
  • Avoiding high-fat, heavy lunches
  • Avoiding consumption of caffeinated or alcoholic beverages

Signs and symptoms of heat risks

It’s important to recognize how often you go to the restroom, as this could be a sign of heat-related illnesses. For more information on how to determine if you are dehydrated, see the infographic provided by the U.S. Army Public Health Command.

Early signs of heat exhaustion include: dizziness, headache, lethargy, muscle cramping and nausea/vomiting.

If a co-worker exhibits the following signs of heat stroke, call 911 immediately. A heat stroke is a medical emergency. Heat stroke symptoms include: red, hot, dry skin, confusion, slurred speech, convulsions and fainting.

What can you do if a co-worker is experiencing the symptoms of heat exhaustion or heat stroke?

  • Relocate to a cooler location
  • Lie down
  • Discontinue activity
  • Drink water or an electrolyte sports drink
  • Mist skin with cool water

Construction workers should keep a close eye on work and weather conditions throughout the day. OSHA developed a Heat Safety Tool that is compatible with iPhone and Android that offers vital safety information any time, any place. “The App allows workers and supervisors to calculate the heat index for their worksite, and, based on the heat index, displays a risk level to outdoor workers. Then, with a simple 'click,' you can get reminders about the protective measures that should be taken at that risk level to protect workers from heat-related illness.”
