Summer in Ontario is typically hot and dry, which can cause heat stress for outdoor workers who work long hours. Heat stress is a seasonal hazard that can occur when the body's core temperature rises, causing severe dehydration that can be harmful if left untreated. 

In this episode of the IHSA Safety Podcast, Jasmine Kalsi, IHSA's Occupational Hygienist, discusses heat stress in detail. Jasmine explains the different types of heat stress disorders, actions to take when experiencing symptoms, tools that can be used to determine heat stress, such as Humidex and Wet Bulb Glove Temperature (WBGT), and controls workplaces can implement to protect workers. Jasmine also shares the free resources IHSA provides for heat stress, such as safety talks, manuals, bulletins, and advisories.
