For people whose jobs are outdoors — construction, agriculture, landscaping, road work, forestry, oil and gas, postal carriers — wildfire smoke is an occupational hazard governed by occupational health and safety rules. Both BC and Alberta publish guidance for employers on smoke-related hazards, and in the US, federal OSHA and several state programs (such as Cal/OSHA, with its wildfire-smoke standard) do the same. The basic expectations are: monitor the AQHI at the job site, provide access to a cleaner indoor area for breaks, supply NIOSH-certified N95 or equivalent respirators when outdoor exposure cannot be reduced, and adjust the schedule (move strenuous tasks to early morning, reduce duration, or pause work) at high AQHI levels. Employees should know the signs of smoke exposure — eye and throat irritation, headaches, chest tightness, fatigue — and have permission to take breaks when symptoms appear. Workers with asthma, heart conditions or pregnancy should discuss accommodations with their employer and physician. If you are a worker and your employer is not providing reasonable smoke protection during a major event, contact your OHS body: WorkSafeBC in BC, Alberta OHS in Alberta, or your state OSHA office or federal OSHA in the US. This is not an optional courtesy — it is a workplace health-and-safety obligation.
