Heat Illness Prevention 

Workers who are exposed to extreme heat or work in hot environments may be at risk of heat stress. Heat stress can result in heat stroke, heat exhaustion, heat cramps, or heat rashes.

Learn to recognize the symptoms of heat stress

Employers and workers should become familiar with the heat symptoms. When any of these symptoms is present, time is of the essence. These conditions can worsen quickly and result in fatalities. When in doubt, cool the worker and call University Police (631-632-3333).

OSHA Heat-Related Illnesses and First Aid 

Heat-related illnesses can be prevented

  • Hydrate before, during and after work. Drink 1 cup of cool water every 20 minutes even if you aren’t thirsty. For longer jobs, drinks with electrolytes are best. Avoid energy drinks and alcohol.
  • Find shade or a cool area for rest breaks that allow your body to recover.
  • Dress for the heat. A hat and light-colored, loose-fitting (where allowed), breathable clothing are ideal.
  • If wearing a face covering, change it if it becomes wet or soiled. Check on others verbally often.
  • Not everyone tolerates heat the same way. Understand personal risk factors.
  • Understanding engineering controls, work practices, and PPE.
