RICHMOND, B.C. — With wildfires a constant threat and unprecedented temperatures lingering over the province, WorkSafeBC is urging employers to prepare for the health and safety risks associated with extreme heat and wildfire smoke.

“Hot and smoky conditions during the summer months create challenges for both indoor and outdoor workers,” said Todd McDonald, head of prevention services at WorkSafeBC, in a statement.

“With hazards related to extreme heat becoming more frequent in recent years, employers need to assess risks early and implement effective plans and controls to protect their workers.”

Between 2020 and 2024, WorkSafeBC accepted 315 heat-related injury claims, with the highest numbers in transportation, public works, construction, food services and film and television production.

When it comes to extreme heat, employers must re-evaluate their indoor workplace conditions and implement appropriate controls, such as ventilation, rest breaks and access to cool drinking water.

During the summer months, outdoor workers also face risks associated with UV rays.

Prolonged sun exposure can cause skin damage with outdoor workers 3.5 times more likely to develop skin cancer than indoor workers, the organization reports.

In addition to heat, there is also the threat of wildfire smoke, which contains fine particulate matter and toxic gases that can penetrate into the lungs, aggravate

respiratory conditions like asthma and increase the risk of both lung and heart disease. As such, wildfire smoke should be treated as a hazardous substance.

“Employers have a responsibility to protect their workers from heat stress and poor air

quality,” added McDonald. “Employers should also involve workers in identifying hazards and developing solutions, which leads to stronger and more effective safety outcomes.”
