in 2022, the International Agency for Research on Cancer (IARC) classified "occupational exposure as a firefighter" as a Group 1 carcinogen, meaning there is sufficient evidence that firefighting can cause cancer in humans.

Polycyclic Aromatic Hydrocarbons (PAHs):

What Firefighters Need to Know

What Are PAHs?

Polycyclic aromatic hydrocarbons (PAHs) are a group of chemicals formed during the incomplete burning of carbon-containing materials like fuels and organic matter. They are commonly found in smoke and soot.

Why Are PAHs a Concern?

PAHs are known for their potential health risks, including cancer. They can be present in both smoke from fires and diesel exhaust, posing a significant risk to firefighters.

How Firefighters Are Exposed

  1. Through Smoke and Soot: When fighting fires, firefighters come into contact with smoke and soot that contain PAHs. These chemicals can settle on the skin and gear.

  2. Skin Absorption: PAHs can penetrate the skin’s outer layer, thanks to their ability to dissolve in fats and oils. Once absorbed, they enter the bloodstream and can pose health risks.

  3. Diesel Exhaust: Firefighting vehicles and equipment that use diesel engines release exhaust containing PAHs, adding another source of exposure.

Protecting Against PAH Exposure

  • Use Proper Gear: Wear well-maintained protective clothing and gloves to reduce direct contact with PAHs.

  • Clean and Decontaminate: After exposure, thoroughly clean and decontaminate equipment and gear to remove PAHs.

  • Practice Good Hygiene: Wash your skin and any exposed areas with soap and water to eliminate residual PAHs.

By understanding how PAHs affect health and implementing these protective measures, firefighters can better safeguard their well-being while performing their crucial duties.
