Do You Know How to Recognize the Signs of Heat Illness?



With record-setting temperatures becoming the norm in many areas, heat safety is more important than ever

Although illness from heat exposure is preventable, thousands of workers become sick every year from heat exposure on the job, and it can be deadly. Help keep you and your coworkers safe by staying vigilant for the warning signs of heat illness.
If a coworker or someone you know shows abnormal thinking or behavior, slurred speech, seizures, or loss of consciousness while on the job, call 911 immediately and take steps to cool them right away.

Keep on the lookout for the warning signs of heat illness:
  • Headache or nausea
  • Weakness or dizziness
  • Heavy sweating or hot, dry skin
  • Elevated body temperature
  • Thirst
  • Decreased urine output
It’s not only outdoor workers at risk for heat illness. Exposure can happen both indoors and outdoors, and can happen any time when the conditions are right.
Keep heat safety information at your fingertips by downloading the OSHA-NIOSH Heat Safety Tool, a handy mobile app you can use to get vital information on first aid, safety precautions and more. For more information on heat safety and work, visit
