The approach of summer is a reminder to us all of the need to recognize, and act to prevent, the harmful effects of excessive heat. The White House has designated May 23–27, 2016, as Extreme Heat Week, during which Federal agencies will work with community planners and public health officials to enhance community preparedness for extreme heat events. Workers are particularly vulnerable to the health impacts of heat exposure. Workers may experience longer or more intense heat exposures and are more likely to engage in strenuous physical activity in the heat than the general public. Also, in many cases workers rely on their employers to provide opportunities for limiting their time in the heat, ensuring adequate rest breaks, and promoting hydration.
