Ontario is encouraging employers and workers to learn how to protect themselves from heat stress this summer.

As summer days get hotter, the harm caused by too much heat can become a significant problem in many workplaces.  Workers and their employers must take steps to protect themselves from the effects of this hazard.

When heat is combined with other factors like hard physical work, fluid loss, fatigue or some medical conditions, it can lead to illness, disability and even death.  Heat stress can affect anyone, including the young and fit, and can be a concern in many workplaces.

Symptoms of heat stress can include excessive sweating, headache, rashes, cramping, dizziness and fainting.
