WE-CAN field campaign data helps estimate wildland firefighter smoke exposure

Wildfire smoke is a common hazard for wildland firefighters who work long shifts under tough conditions. However, exactly how much smoke a firefighter is exposed to depends on their job task, wind speed and direction, where they are stationed, and more, according to a new study published in Environmental Science & Technology. Using data from a field campaign supported by CPO’s Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program, the study found that almost a fifth of exposures were above the recommended occupational exposure limit, suggesting wildland fire management should find strategies to reduce smoke exposures.
