Working in Extreme Heat: 5 Things You Didn't Know

Construction workers take a break on a hot day. mobile view

We all know the standard advice for working outside during the summer: take frequent breaks in the shade, drink lots of fluids and wear sunscreen. Since you already know the basics, here are some lesser-known facts about working safely in the summer heat. 

Some Workers are More Likely to Be Affected Than Others 

Any of your employees can sustain a heat-induced illness under the right conditions, but there are certain people who are more vulnerable and may need to take extra precautions. These include people who have high blood pressure or heart disease, are overweight, have a previous history of heat illness or those who take allergy medication, decongestants or blood pressure medication. 

Not All Fluids Are Created Equal 

During hot weather, outdoor workers are commonly advised to drink lots of fluids. But did you know that very sugary drinks (like soda) and beverages containing alcohol or caffeine can actually cause you to lose more body fluid? Temperature is a factor, too, because drinking very cold liquid can cause stomach cramps. OSHA recommends drinking small amounts of cool water frequently.

You May Actually Need More Salt While Working In Extreme Heat 

Heavy sweating can deplete the salts and minerals your body needs to function. You can replace these with a sports drink, though the electrolytes you get through regular meals and snacks will usually do the trick as well (talk with your doctor if you are on a low-salt diet). 

Heat Illness May Take Workers by Surprise 

Heat illness can cause confusion and poor judgement, so employees may not realize they are getting sick. Monitor your workers during extreme heat and make sure all employees know the symptoms of heat-induced illnesses so they can help keep an eye on each other. 

Immediate Action Can Save a Life

If you or an employee notice the symptoms of severe heat illness (confusion, vomiting or loss of consciousness), it’s important to act immediately. Call 911, move the person to a cooler location and do your best to reduce the person’s body temperature by applying cool cloths or wetting their clothing.
