Wildland firefighters are exposed to airborne particulates, polycyclic aromatic hydrocarbons (PAHs), and other hazardous substances. Respiratory protection is indicated, but information lacking on the tasks conditions for which mask wearing should be advised. Studies assess respiratory in wildland were carried out western Canada 2021 2023. Sampling pumps measured exposures urinary 1-hydroxypyrene (1-HP) was assayed indicate PAH absorption. Participants reported time they wore during each task. In 2023, use of masks reported, rated smoke intensity. 2021, 72 monitored over 164 shifts and, 89 263 shifts. highest those engaged initial attack hot spotting. Urinary 1-HP at end rotation reporting attack, working a prescribed fire mop-up. firefighter ratings intensity strongly associated with particulate mass 1-HP, not worn more often when there higher The data from literature did provide clear indication high-exposure tasks. Better task/exposure needed make informed decisions about wearing.
