WITH wildfire conditions changing across parts of the province, WorkSafeBC is reminding employers to assess wildfire-related risks and take steps to protect workers from smoke exposure and other potential hazards. 

Wildfire smoke contains fine particulate matter that can travel long distances and affect workers far from active fire zones. Exposure can cause coughing, throat irritation, headaches, and shortness of breath, and may pose greater risks for workers with underlying health conditions and those performing physically demanding work outdoors.  

“Air quality conditions can change quickly during wildfire season,” says Todd McDonald, Head of Prevention Services at WorkSafeBC. “Employers should monitor conditions closely and be prepared to adjust work activities as needed to protect workers.” 

In areas where wildfire activity may escalate, employers should also review their emergency preparedness and response plans. Employers are required to assess workplace risks where evacuation or rescue may be necessary and ensure workers are aware of evacuation procedures, emergency communication methods, and designated escape routes. 

Employers are required to assess workplace risks and implement appropriate measures to reduce exposure. When wildfire smoke is present, there are several actions employers can consider, including: 

• Learn the common symptoms of smoke exposure, including sore throat, runny nose, eye irritation, mild cough, wheezy breathing, and headaches. 
• Monitor local air quality advisories and forecasts. 
• Relocate or reschedule work to avoid periods of heavier smoke exposure. 
• Reduce physically demanding tasks when air quality deteriorates. 
• Assign alternate work to employees who may be more sensitive to smoke. 
• Provide appropriate respiratory protection when required and ensure respirators are fit tested. 

Employers should also take steps to reduce smoke exposure in indoor workplaces by: 

• Ensuring HVAC systems are operating properly and filters are clean. 
• Using portable air cleaners where appropriate. 
• Consulting with qualified ventilation specialists before modifying building ventilation systems. 
• Advising workers who drive as part of their job to keep windows closed and use the recirculation setting in their vehicles. 

Workers should report symptoms or concerns to their employer and follow established workplace procedures for responding to deteriorating air quality.
