The past few summers have shown that the risk of heat illness from high temperatures is one of the most serious challenges to the safety and health of workers. The Heat Illness Prevention Training Guide will help you plan how to prevent heat illness among your crew and provide training to your workers. The training guide includes the following tools for the supervisor or crew leader to use: Complete instructions for teaching workers about heat hazards and additional resources. Why is it important to prevent heat illness? Heat illness can be a matter of life and death. Workers die from heat stroke every summer and every death is preventable. When heat stroke doesn't kill immediately, it can shut down major body organs causing acute heart, liver, kidney and muscle damage, nervous system problems, and blood disorders. Having a serious injury or death occur at work affects everyone at a worksite. Workers suffering from heat exhaustion are at greater risk for accidents, since they are less alert and can be confused. Providing short training sessions can be a very efficient way to reach workers with health and safety information. Like all training, making sure you are effective in communicating the information takes preparation and a real desire to involve your crew in health and safety. In this guide, you will find some advice for trainers that can help encourage discussion and enable workers to be active players in keeping the job safe.
