We're in the middle of the summer heat wave, which brings elevated temperatures and the threat of heat exposure for workers outside. Stress levels increase on these crews as their bodies expend more energy to function in the heat. To battle these strains, workers need to take the time to allow their bodies to adjust to the increased temperatures.
Most people adapt to the weather or acclimate within 4 to 14 days of normal work levels,
according to Cal/OSHA heat illness prevention data.
The acclimation process: On the first day of work in a hot environment, the body temperature, pulse rate, and general discomfort will be higher. With each succeeding daily exposure, all of these responses will gradually decrease, while the sweat rate will increase. When the body becomes acclimatized to the heat, the worker will find it possible to perform work with less strain and distress.
Employees are encouraged to:
Don't push yourself too hard or too fast to complete work assignments in the heat. Get used to the changing work conditions. Pace yourself.
Be sure to take regular, scheduled breaks.
Wear light, layered clothing. Wear a hat and use sunscreen.
Drink fluids often. Dehydration is a significant concern for all workers in elevated temperatures.
Be sure to communicate. If you feel dizzy, tired, confused, or disoriented – tell your supervisor immediately. This could be a serious condition.
Some health conditions can put workers at greater risk of heat-related illness. These include diabetes, kidney and heart problems, pregnancy, and being overweight. Additionally, the risk of dying from heat illness appears to be highest for employees who just begin working in extreme heat, as the body needs to adapt gradually to heat and humidity.
If you have any questions about the exposure to the heat, please contact either your supervisor or Human Resources (HR).
