Editor’s Note: The following information is taken from the U.S. Department of Labor, OSHA website at www.osha.gov/SLTC/heatstress/heat_illnesses.html. Cleaner Times | IWA realizes that summer started on June 21 and desires that everyone in the industry remain safe during these warmer months.

Heat Stroke:

The most serious form of heat-related illness happens when the body becomes unable to regulate its core temperature. Sweating stops and the body can no longer rid itself of excess heat. Signs include confusion, loss of consciousness, and seizures. Heat stroke is a medical emergency that may result in death! Call 911 immediately.

     -Symptoms-

       • Confusion
       • Fainting
       • Seizures
       • Excessive sweating
       • Very high body temperature

     -First Aid-

       • Call 911
       While waiting for help:
       • Place worker in shady, cool area
       • Loosen clothing, remove outer clothing
       • Fan air on worker; cold packs in armpits
       • Wet worker with cool water; apply ice packs, cool compresses, or ice if available
       • Provide fluids (preferably water) as soon as possible
       • Stay with worker until help arrives

Heat Exhaustion:

This is the body’s response to loss of water and salt from heavy sweating. Signs include headache, nausea, dizziness, weakness, irritability, thirst, and heavy sweating.

     -Symptoms-

       • Cool, moist skin
       • Heavy sweating
       • Headache
       • Nausea or vomiting
       • Dizziness
       • Light headedness
       • Weakness
       • Thirst
       • Irritability
       • Fast heart beat

     -First Aid-

       • Have worker sit or lie down in a cool, shady area
       • Give worker plenty of water or other cool beverages to drink
       • Cool worker with cold compresses/ice packs
       • Take to clinic or emergency room for medical evaluation or treatment if signs or symptoms worsen or do not improve within 60 minutes
       • Do not return to work that day

Heat Cramps:

These are caused by the loss of body salts and fluid during sweating. Low salt levels in muscles cause painful cramps. Tired muscles—those used for performing the work—are usually the ones most affected by cramps. Cramps may occur during or after working hours.

     -Symptoms-

       • Muscle spasms
       • Pain
       • Usually in abdomen, arms, or legs

     -First Aid-

       • Have worker rest in shady, cool area
       • Worker should drink water or other cool beverages
       • Wait a few hours before allowing worker to return to strenuous work
       • Have worker seek medical attention if cramps don’t go away

Heat Rash:

Also known as prickly heat, this is skin irritation caused by sweat that does not evaporate from the skin. Heat rash is the most common problem in hot work environments.

     -Symptoms-

       • Clusters of red bumps on skin
       • Often appears on neck, upper chest, folds of skin

     -First Aid-

       • Try to work in a cooler, less humid environment when possible
       • Keep the affected area dry
