Due to wildfires in Canada causing smoke to take over the northeastern parts of the U.S., the Occupational Safety and Health Administration (OSHA) has offered additional information to protect outdoor workers. The most significant hazard from wildfire smoke is exposure to particulate matter, tiny particles of partially burned material less than 2.5 micrometers in diameter, that can enter the lungs and even the bloodstream and is linked to serious health problems, including lung, heart and kidney disease.
Workers exposed to smoke-polluted air may experience heat stress, eye and respiratory tract irritation, and suffer from exposure to other respiratory hazards caused by hazardous substances such as heavy metals entering the atmosphere. Employers should prepare for and plan to implement procedures to reduce exposures to smoke when necessary.
