Bodies cool themselves through the act of sweating but during hot weather, especially when paired with high humidity, sweating simply isn't enough. Body temperatures can rise to dangerous levels if proper precautions are not taken. Heat related illnesses can vary from the appearance of a heat rash and heat cramps to heat exhaustion and even heat stroke, which can lead to death and requires immediate medical attention. It is very important that employees know the signs and symptoms of these conditions and the proper methods for prevention.
OSHA recommends employees working outdoors in heated conditions take the following preventative measures:
Jobs where employees are most affected by heat-related illness include positions in construction, transportation/utility, agriculture and building/grounds maintenance and cleaning. Other workers who may be affected by exposure to environmental heat include those in transportation/baggage handling, water transportation; landscaping services; greenhouse, nursery, and floriculture production; and support activities for oil and gas operations. OSHA sums up the key to their campaign in three simple words: water, rest and shade.
