Chief compliance officer Richard Blais tells CHSJ News heat can build up in places like restaurant kitchens, laundries and pulp mills causing heat exhaustion or stroke.
He says proper ventilation and fans can help keep heat from building up when working indoors.
Blais says for people who work outdoors it's best to try and do the heaviest work during the coolest parts of the day, such as early in the morning or late at night.
He says if you experience warning signs like headache or dizziness it's important to drink water, slow down the pace or work in the shade for a while.
