Avoiding Heat-Related Illness

Every year, dozens of workers die and thousands more become ill while working in extreme heat or humid conditions. There are a range of heat illnesses and they can affect anyone, regardless of age or physical condition. During times of intense heat, workers can be at serious risk of illness, over-exhaustion and potentially even death.

As summer temperatures soar, employees who work outdoors are especially susceptible to heat-related illnesses. Similarly, workers in indoor environments can also fall victim to excess heat exposure.

Below are few areas that, if followed will help to eliminate heat related illnesses.

Hydration – When a worker is adequately hydrated body processes can occur and help maintain the body’s core temperature.  When a worker is dehydrated, the body temperature rise and develop into a heat related illness.  Drink cool fluids.  Stick to water or sports drinks.  Don’t drink any beverages that have alcohol or caffeine, either of which can contribute to fluid loss.

Work-to-Rest Ratio – Once temperatures reach 75 degrees, begin adjusting work-to-rest ratios.  OSHA has temperature-dependent guidelines for workers doing light, moderate and heavy work.  For light work, the defined temperature is 86 degrees, 80 degrees for moderate work and 77 degrees for heavy work. OSHA guidelines suggest that workers shouldn’t be subjected to those temperatures for more than two hours without a break.

Body Cooling – Preventing body temperatures from reaching dangerous levels is key to preventing heat related illnesses.  Rest in a cool place.  Getting into an air-conditioned building is best, but at least find a shady spot if necessary.  Loosen clothing and remove outer layers of clothing to allow the body to cool off and receive air flow.  Apply cool water to your skin.  Take a cool shower or drench yourself with a water hose if possible.
