The wildfire smoke mixing with near-40 degree temperatures later this week will make for some less than ideal conditions outside.
And for many working in jobs that keep them outdoors, it can be a challenge.
WorkSafeBC Prevention Field Services Director Dan Strand says there are simple things people shouldn't ignore.
"Water's what you want to be drinking, one glass every 20 minutes in extreme heat," he said.
"Staying hydrated is one of the main components of protecting workers themselves, but again, taking those breaks and determining how many breaks, and at what length, in a well-ventilated area."
He says last year, there were 16 claims made to the agency for work-related injuries that were caused by people being under heat stress.
Strand says based on that, people shouldn't try to be a hero, and power through it.
"There's been up to 200 claims in the past 10 years, in the occupations such as outdoor workers, lifeguards, recreation/fitness leaders, truck and bus drivers, actually, as well as folks in the motion picture industry," he said.
17 claims have come from the Central Okanagan region, dating back to 2007.
