BURSTWorkSafeBC has issued a bulletin to remind employers that they must protect their workers from heat-related illnesses as Environment Canada issues heat alerts.
This applies to staffers working inside and outside.
Todd McDonald, WorkSafeBC’s head of prevention services, warned that higher temperatures by nature increase the risk of heat stress and heat stroke, “which can be serious and even life-threatening.
“These illnesses are preventable, and employers have a responsibility to take steps to protect workers, whether they are indoors or outdoors,” McDonald said.
WorkSafeBC received 335 heat-related injury claims between 2021 and 2025, with 47 of them in 2025.
The July 21 bulletin notes those working in construction, agriculture, transportation, and public works are at higher risk but people working indoors — such as in kitchens, warehouses, and manufacturing buildings — are also susceptible, particularly if there’s no air conditioning.
WorkSafeBC requires employers to conduct risk assessments and develop safety plans.
Accordingly, they should provide cool drinking water and regular rest breaks, set up shady or cooled recovery areas, schedule strenuous task during cooler times in the day, improve ventilation, and rotate workers between hotter and cooler environments.
Employers also need to train their workers to recognize early signs of heat stress and how to access first aid. The bulletin notes that symptoms can include excessive sweating, muscle cramps, nausea, weakness, dizziness, agitation and confusion.
Workers should report symptoms and be encouraged to speak up if things are not safe.
Employees during hot weather should also drink lots of water – a glass every 20 minutes – wear sunscreen, wear light breathable clothing like cotton, be aware of their personal risks related to medications or health conditions, and watch for signs of heat stress in themselves and co-workers.
Anyone with questions about heat stress can call 604-276-3100 or toll-free at 1-888-621-7233 for information.
