January is Fire Fighter Cancer Awareness Month

Jan. 3—Firefighting is known to be a dangerous profession. In addition to the obvious risks of running into burning buildings, the men and women of professional and volunteer fire departments are at an increased risk for something else—cancer.

In fact, occupational cancer is the leading cause of line-of-duty deaths in the fire service, according to the International Association of Fire Fighters (IAFF).

At the 2023 IAFF Fallen Fire Fighter Memorial, 63 % of the names added to the wall were members who had died from occupational cancer.

Recent studies by the National Institute for Occupational Safety and Health (NIOSH) that focused on firefighter cancer found that compared to the general population, firefighters had a 9 % increase in cancer diagnoses and a 14 % increase in cancer-related deaths.

This increased risk is due to the smoke and hazardous chemicals they are routinely exposed to, including a variety of synthetic and plastic materials that, when burned, release a number of carcinogens (cancer-causing agents). This includes exposure to things like arsenic, asbestos, benzene, diesel exhaust, formaldehyde, radioactivity, sulfuric acid and dozens of other possible carcinogens that can be inhaled or absorbed through the skin.

The International Agency for Research on Cancer (IARC), the specialized cancer agency for the World Health Organization (WHO), recently classified the firefighting occupation as carcinogenic to humans, placing the job in Group 1—the IARC's highest carcinogenic hazard classification.

Previously, IARC had classified firefighter occupational exposure as Group 2B—possibly carcinogenic to humans. The new classification as Group 1 puts firefighting on par with tobacco and benzene as carcinogenic to humans.

The personal protective equipment (PPE) worn by firefighters, generally called turnout gear, can offer some protection from carcinogens, but if not properly cleaned can carry contaminants from fire scenes, cross-contaminating everything it touches. The gear itself also poses a cancer threat.

Lab-made chemicals known as PFAS (perfluoroalkyl and polyfluoroalkyl substances), which have been linked to cancer and other diseases, are used in most turnout gear.

PFAS are helpful in making products that resist oils, stains, water and heat.

Since the 1940s, PFAS have been used commercially to make non-stick coatings on cookware, as well as protective coatings for products like carpets and fabrics. They have also been used in coatings for paper and cardboard food packaging, firefighting foams, ski wax and some other products.
