As you may/may not realize, Firefighters are exposed to potentially dangerous levels of ultrafine particulates at the time when we are least likely to wear our SCBA. Because of this, researchers believe we may face an increased risk for heart disease from exposures during firefighting and overhaul.
In a study conducted collaboratively by the University of Cincinnati (UC), Underwriters Laboratories (UL) and the Chicago FD, researchers have found that more than 70 percent of particulates released during fires are "ultrafine," invisible to the naked eye but able to be inhaled into the deepest compartments of the lung.
