Draft Hazard Review: Wildland Fire Smoke Exposure Among Farmworkers and Other Outdoor Workers
On March 14, 2024, NIOSH published a Request for Information (RFI) in the Federal Register announcing plans to develop a Hazard Review document that summarizes the scientific literature about the health effects from exposures to wildland fire smoke and provides recommendations to protect outdoor workers [NIOSH 2024]. In response to the RFI, NIOSH received 10 comment submissions, all of which were reviewed and considered during the development of this draft Hazard Review. The Hazard Review development process involved review and assessment of the scientific literature about exposures to wildland fire smoke, potential health effects, outdoor worker populations at risk, and development or update of recommendations to protect outdoor workers. The purpose of the Hazard Review document is to provide an overview of the relevant health effects literature and present evidence-based recommendations to protect outdoor workers, including farm workers, construction workers, oil and gas workers, park rangers, emergency responders, and others from the adverse health effects of occupational exposure to wildland fire smoke. The information presented in this Hazard Review represents the scientific rationale and the current methodology about approaches to assess and control the hazards of wildland fire smoke to outdoor workers. Scientific information related to wildland fire smoke presented in the Hazard Review covers the following topics:
- Background on wildland fire smoke
- History of NIOSH and other government organizations’ related activity
- Chemical and physical properties of the smoke
- Population of outdoor workers with potential exposure
- Routes of worker exposure
- Health equity
- Health effects of exposure
- Exposure assessment
- Controlling workplace exposures
- Medical surveillance and medical monitoring
- Research needs
On September 13, 2024, NIOSH published a notice in the Federal Register announcing public comment and technical review on the draft Hazard Review. Written comments were to be received by November 12, 2024. NIOSH is extending the public comment period to January 10, 2025.
NIOSH will also convene an informational webinar to present an overview about the draft Hazard Review document, describe its content and purpose, and provide information about the public comment period. The webinar is scheduled to occur on Tuesday, December 3, 2024, at 1:00 PM Eastern Time (US and Canada). Attendees are requested to register in advance for this webinar.
