As the weather starts to get warmer in the northern hemisphere, the daily risks of heat stress and heat stroke increase. Workers in outdoor environments like those working in the utilities, oil & gas, and construction industries are at a greater risk. Heat stress occurs when the body’s natural cooling processes fail to effectively regulate body temperature. Signs of heat stress can include fatigue, exhaustion, headaches, flu-like symptoms, cramping, dizziness, rash from excessive sweating, fainting and more. Not only is heat stress a health hazard, workers suffering from heat exhaustion are at greater risk for accidents since they are less alert and may not be able to think clearly. It is important to know the risks of heat stress and how to properly mitigate them to stay healthy and productive.
