This report addresses exposure to smoke from wildland and prescribed fires encountered by wildland firefighters. Smoke from vegetation as well as off-gasses from equipment such as chain saws, pumps, and drip torches are accounted for. Section II provides an overview of industrial hygiene science and techniques. Section III is a discussion and literature review of the components in wildland smoke, and section IV identifies the health concerns associated with smoke inhalation and a review of the current literature on exposure to inhalation irritants. Section V covers research that has been done on wildland firefighter smoke exposure. Section VI is an overview of the Wildland Firefighter Smoke Exposure Study, a project I have managed since 2009. This final section describes the objectives, methods, data collection, and analysis of the study. In its entirety, this report can be used to identify locations, times, and firefighter activities that have a high probability of causing high exposures as well as to identify management actions that can mitigate these exposures. Wildland firefighters work in a dynamic environment and are often faced with a variety of hazards from fire to fire and shift to shift. One of the most common, but often overlooked, hazards is exposure to potentially harmful levels of contaminants in wildland smoke. This may also be one of the least understood risks of wildland firefighting (Reisen et al., 2009). With a growing body of information regarding the potential health effects of vegetative smoke to respiratory and cardiovascular systems, it became apparent to United States Forest Service (USFS) fire management officials that more research needed to be done. The USFS realized the need for current, valid data to accurately assess the exposure wildland firefighters and personnel at fire camps experience during their work shift. Unlike municipal firefighters, wildland firefighters do not wear respiratory protection equipment such as a self-contained breathing apparatus (SCBA). Without SCBA, wildland firefighters are subject to exposure from a variety of inhalation irritants ranging from carbon monoxide, aldehydes, particulate matter, crystalline silica, and polycyclic aromatic hydrocarbons. Some of the compounds in wildland fire smoke are known or suspected carcinogens. Health effects include short-term conditions such as headaches, fatigue, and nausea, while long-term health effects may include an increased risk of cardio-vascular disease. In order to assess the long-term risks associated with wildland firefighting, a comprehensive study of exposure was necessary. By identifying the conditions and activities that lead to high exposure, firefighters and fire managers can be better prepared to reduce these exposures. This study focused on wildland firefighters engaged in the suppression of wildland fires and working on prescribed fires primarily on federally-managed lands (forests and rangelands) throughout the United States. Study subjects included any firefighter employed by the following federal land management agencies: US Forest Service, National Park Service, Fish and Wildlife Service, Bureau of Indian Affairs, and the Bureau of Land Management, as well as employees contracted by these federal agencies. Firefighters employed by various states are also included in the study, as well as those engaged in initial attack and project fires. Study subjects also included fire support personnel who work at incident command posts (ICPs) and spike camps. Fire suppression and management of prescribed fires involves many different activities. In order to successfully account for differences in exposure among firefighters, these activities were monitored and recorded during the data collection phase.

California and other wildfire-prone western states have experienced a substantial increase in the number and intensity of wildfires in recent years. Wildlands and climate experts expect these trends to continue and quite likely to worsen in coming years. Wildfires and other disasters can be particularly devastating for vulnerable communities. Members of these communities tend to experience worse health outcomes from disasters, have fewer resources for responding and rebuilding, and receive less assistance from state, local, and federal agencies. Because burning wood releases particulate matter and other toxicants, the health effects of wildfires extend well beyond burns. In addition, deposition of toxicants in soil and water can result in chronic as well as acute exposures. On June 4-5, 2019, four different entities within the National Academies of Sciences, Engineering, and Medicine held a workshop titled Implications of the California Wildfires for Health, Communities, and Preparedness at the Betty Irene Moore School of Nursing at the University of California, Davis. The workshop explored the population health, environmental health, emergency preparedness, and health equity consequences of increasingly strong and numerous wildfires, particularly in California. This publication is a summary of the presentations and discussion of the workshop.

Background: Wildland firefighters are repeatedly exposed to elevated levels of wildland fire smoke during wildfire suppression and prescribed burns. Information of wildland fire smoke exposure of wildland firefighters is only available for the western and southeastern United States, and no assessment of this occupational exposure has been reported for the midwestern region. Since different geographic areas have unique vegetative fuels, soil characteristics, and fire conditions, wildland firefighters working in the midwestern states might be exposed to different levels of wildland fire smoke with different particle compositions. As past studies of more disease-relevant outcomes have been mostly limited to pulmonary and respiratory responses, acute cardiovascular effects and systemic oxidation due to occupational wildland fire smoke exposure were investigated among wildland firefighters. Objectives: The specific aims of this study are to 1) characterize occupational exposure of wildland firefighters to air pollutants, including particulate matter with aerodynamic diameter equal to or less than 2.5 microns (PM2.5), carbon monoxide (CO), black carbon (BC), and trace metals in wildland fire smoke emissions from prescribed burns in the midwestern United States; 2) assess the effect of wildland fire smoke exposure on acute cardiovascular responses by investigating cross-shift changes in hemodynamic parameters, blood pressure (BP) and heart rate (HR), among wildland firefighters on prescribed burn days and compare those to the corresponding changes on regular work days; 3) determine the effect of wildland fire smoke exposure on systemic oxidation by studying cross-shift changes in oxidative biomarkers, 8-isoprostane, malondialdehyde (MDA), and oxidized guanine species (Ox-GS) in spot urine samples collected from wildland firefighters on prescribed burn days and their associations with urinary mutagenic potency; and 4) investigate task-related difference (holding, lighting, others) in personal exposure concentrations of air pollutants, in resting BP and HR, and in oxidative biomarkers and urinary mutagenicity. Methods: Exposure concentrations of PM2.5 and CO were monitored in the breathing zoom of wildland firefighters working at prescribed burns. Following the sampling, smoke particulate constituents, BC and heavy metals, were quantified using the light absorption technique and inductively coupled plasma mass spectrometry (ICP-MS), respectively. Exposure concentrations of air pollutants were further categorized based on work tasks (holding, lighting, and others) in prescribed burn shifts. Resting BP and HR and spot urine sample were measured/collected right before (pre-shift), immediately after (post-shift), and next morning (next-morning) of prescribed burn shifts (burn days) as well as regular work shifts (non-burn days). The levels of urinary oxidative biomarkers were determined using commercially available assay kits and urinary mutagenic potency was assessed using the Salmonella (Ames) mutagenicity assay. Linear mixed effect model was used to examine if the cross-shift changes (i.e. post-shift or next-morning vs. pre-shift) in BP and HR measures and the levels of urinary mutagenicity and oxidative biomarkers on burn days are significant. Difference in cross-shift changes in the hemodynamic parameters and urinary biomarkers were compared between burn and non-burn days using linear mixed effect model. Results: Wildland firefighters in the Midwest had personal PM2.5 and CO exposure concentrations that were about 2-7 times higher than the other regions. Twenty-eight personal CO exposure concentrations were ever above the National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL) Ceiling (200 ppm) for CO. Wildland firefighters who maintained the fires in the boundaries of burning areas had higher CO exposure concentrations compared to those who lighted fires (p
