Risk from Wildfire Smoke: Managing Hidden Health Impacts on Global Workforces
Updated
Wildfires have been disrupting operations and communities across multiple continents in 2026, from North America and Europe to parts of Asia, Latin America, Australia, and Africa. For most organizations, risk from wildfires still gets treated as a property problem or a local operations issue. That view misses the bigger threat. Wildfire smoke is a workforce health issue, and its reach extends far past the fire line itself.
Smoke exposure and hazardous air quality can travel hundreds of miles from an active fire, affecting workforce members who never see a flame. Organizations that only plan for the visible threat, fire damage to buildings and disruption to travel, are missing the hidden one that follows the smoke into offices, homes, and communities well beyond the burn zone.
Key Takeaways
- Wildfire smoke can travel hundreds of miles, putting workforce members outside the immediate fire zone at risk.
- Workforce members with asthma, heart conditions, or respiratory vulnerabilities face heightened exposure risks.
- Wildfire smoke's health impacts often outlast the visible smoke, extending into long-term physical and mental effects.
- Organizations with a proactive Duty of Care framework are better positioned to protect their workforce and maintain business continuity.
Why Wildfire Smoke is a Workforce Risk, Not Just a Local One
The scale of this risk comes down to one factor most organizations overlook: distance.
How Far Can Wildfire Smoke Travel
Air quality can become hazardous even hundreds of miles from an active fire. Smoke particles travel on wind currents well beyond the visible fire zone, degrading air quality in cities and regions that face no direct wildfire threat.
This distance is what makes wildfire smoke a distributed workforce risk rather than a site-specific one. An organization with no operations anywhere near an active fire can still have workforce members breathing hazardous air. Wildfire risk planning has to account for this reach, not just proximity to the fire itself.

Why Standard Air Quality Alerts Aren't Enough for Organizations
Public air quality alerts are built for individuals, not organizations. They tell one person to check an app or stay indoors. They do not tell an HR director or corporate security team whether a distributed workforce across 10 cities needs a coordinated response, nor do they trigger any organizational protocol on their own.
Organizations need a way to monitor conditions across every location where their workforce operates, and to act on that information consistently. International SOS shares air pollution news and guidance on the health effects of pollutants, helping organizations stay informed as conditions change.
"Organizations must critically evaluate whether their emergency preparedness and their approach to employee safety and continuity reflect the reality of how these events unfold," - Joshua Dozor, General Manager, Medical and Security Assistance Services, Americas, at International SOS.
Who is Most at Risk From Wildfire Smoke Exposure
Risk varies across the workforce, and it isn't limited to physical health alone.
Physical Health Risks: Respiratory and Cardiovascular
Workforce members with asthma, heart conditions, or respiratory vulnerabilities face elevated risk during wildfire smoke events. Fine particulate matter in smoke can trigger acute respiratory symptoms and place added strain on the cardiovascular system, even at exposure levels that feel mild to a healthy individual.
Identifying Vulnerable Members of Your Workforce
Organizations do not need medical disclosures to plan for this risk. Practical steps include:
- Build wildfire readiness into existing wellness communications.
- Encourage workforce members to voluntarily and confidentially flag relevant health conditions ahead of wildfire season.
- Pair this with clear guidance on the support available, turning a sensitive topic into a straightforward planning exercise.
The Hidden Impact: Mental and Emotional Wellbeing After the Smoke Clears
Wildfire smoke's effects don't end when the air quality readings improve.
Displacement, Disrupted Routines, and Prolonged Uncertainty
The health impact of a wildfire does not end when the air clears. Dr Mark Fischer, Regional Medical Director at International SOS, notes that organizations should recognise that employee wellbeing can be affected long after visible smoke has cleared. Supporting workforce members means addressing both the immediate physical risks of smoke exposure and the longer-term mental and emotional impacts that can follow displacement, disrupted routines, and prolonged uncertainty.
This is the impact most wildfire safety content overlooks. A workforce member who evacuated, lost days of routine, or spent weeks uncertain about their home's safety carries that disruption well past the event itself.
Supporting Long-Term Resilience
Wellbeing support needs to extend past the acute phase of a wildfire event. Organizations should be prepared to support their workforce through the entire lifecycle of an event, including:
- Timely health guidance during the crisis itself.
- Resources that help workforce members build resilience once the immediate threat has passed.
- Ongoing access to a Workplace Health and Wellbeing partner for support that continues after the headlines move on.
Managing Wildfire Smoke Risk: Building a Plan for Your Organization
A strong plan combines proactive monitoring with clear guidance drawn from real-world response.
Monitoring Air Quality Before it Becomes a Crisis
A few practical measures make a meaningful difference for workforce members exposed to wildfire smoke:
- Keep HEPA air purifiers on hand in offices and, where possible, workforce homes.
- Plan to stay indoors as much as possible when air quality drops.
- Provide N95 masks for anyone required to work outdoors during smoke events.
- Monitor air quality proactively rather than waiting for visible smoke or public alerts.
Most organizations recognise wildfire risk in principle. The harder part for corporate security and occupational health leads is translating that awareness into a practised response protocol. "A recurring challenge is translating that awareness into concrete, practised response protocols," said Joshua Dozor, General Manager, Medical and Security Assistance Services, Americas, at International SOS, pointing to real-world events as a guide for readiness.
How International SOS Helps Protect Your Workforce Through Wildfire Season
Wildfire smoke risk planning is not a single action. It is an ongoing capability, built on air quality monitoring, medical guidance, and wellbeing support that spans the full lifecycle of an event. International SOS' Workplace Health and Wellbeing solutions bring occupational health expertise, access to medical professionals, and workforce wellbeing programs together, so organizations do not have to build this capability on their own.
With nearly 13,000 global experts across more than 1,200 locations in 90 countries, International SOS supports organizations wherever their workforce operates, whether that is inside an active fire zone or hundreds of miles downwind of one.

Frequently Asked Questions About Wildfire Smoke Risk
Organisztions should monitor local air quality indices and communicate updates to the workforce in real time. Provide N95 masks for anyone required to work outdoors. Build wildfire response into your Duty of Care framework, including guidance for workforce members with respiratory or cardiovascular vulnerabilities.
Reduce exposure by closing all windows and doors, and using HEPA air purifiers where possible. Avoid using fans or systems that draw in outside air. If you must go outside, wear an N95 mask to limit exposure.
Wildfire smoke risk isn't limited to regions with active fires. Hazardous air quality can extend hundreds of miles from a fire zone, affecting organisations across North America, Europe, Asia, Latin America, Australia, and Africa. Global organisations should assess exposure across their full footprint, not just locations near known fire-prone areas.
