Safety Nugget Week of May 22 - Heat Related Illness< Back to Blog

We are approaching the hottest months of the year.  The risk of heat related illness is increasing. It is important to remember to drink plenty of water throughout the day.  A rule of thumb is to drink 4 cups of water every hour.  Also, it is important to take frequent breaks in shaded and/or air conditioned areas. The graphic below is taken from osha and displays the common symptoms of heat exhaustion and heat stroke.  However, each person is different, so they may not show all of the symptoms.  If there is every any question about possible heat stroke, call 911.

The risk of heat related illness increases not only with temperature but also humidity. The body cools via evaporation of water while sweating.  The evaporation process slows down the more humid the conditions are.  If possible, schedule the more physically rigorous jobs in the cooler hours of the day.  

Another item to remember, is to wear sunscreen.  Skin cancer is one of the leading types of cancers diagnosed, and many of the cases can be prevented.  If possible wear long sleeves, pants, large brimmed hats, and sun glasses.  The highest risk times for excessive UV radiation exposure is 10 AM to 4 PM.
