Per- and polyfluoroalkyl substances (PFAS) have become a growing concern in firefighting communities due to their presence in firefighter gear and their potential association with increased cancer risks among firefighters. This article aims to provide a comprehensive understanding of PFAS, its presence in firefighter gear, and its potential impact on the heightened cancer risk faced by firefighters.

Understanding PFAS: Basics and Definitions
PFAS, short for per- and polyfluoroalkyl substances, are a class of manufactured chemicals characterized by their resistance to heat, water, and oil. These chemicals have been widely used in various consumer products, including firefighting gear, due to their exceptional water and oil repellency properties. PFAS encompass a broad range of chemicals, notably perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA).
PFAS in Firefighter Gear: Composition and Concerns
Firefighter protective gear, commonly referred to as “turnout gear,” is designed to shield firefighters from the hazards encountered in firefighting situations. This gear comprises distinct layers, each made of different textiles. Concerns have been raised about the potential presence of PFAS in these layers, primarily due to their adverse health effects, including their linkage to cancer.
Cancer Risk among Firefighters: A Heightened Concern
Firefighters face increased cancer risks attributable to their occupational exposures, including smoke, soot, vehicle exhaust, and hazardous materials encountered during firefighting activities. The potential presence of PFAS in their protective gear adds to these concerns, given the known health risks associated with exposure to these chemicals.
NIST Research on PFAS in Firefighter Gear
The National Institute of Standards and Technology (NIST) has conducted comprehensive research to analyze the presence of PFAS in firefighter gear. Their study focused on examining the textiles used in the layers of turnout gear, aiming to quantify and understand the types, quantities, and distribution of PFAS in this essential protective equipment.
Findings and Implications of NIST Research
NIST researchers discovered varying concentrations of PFAS among different manufacturers and layers of turnout gear. The outer layers exhibited higher concentrations, while the layer closest to the skin had lower PFAS levels. The presence of PFAS in firefighter gear raises concerns about potential exposure and health implications for firefighters.
Impact of PFAS on Cancer Risks: Exploring the Connection
The suspected carcinogenic properties of PFAS raise concerns about the potential link between exposure to these chemicals in firefighter gear and the heightened cancer risk observed among firefighters. Understanding how PFAS exposure occurs and its influence on cancer risk is a critical area of investigation.
Mitigating PFAS Exposure in Firefighter Gear
Efforts to reduce PFAS exposure in firefighter gear involve exploring alternative fabric combinations and treatment methods. Identifying ways to minimize or eliminate PFAS from turnout gear while maintaining its protective functions is crucial for mitigating health risks for firefighters.
Future Directions: Research and Protective Measures
Ongoing research initiatives aim to delve deeper into the effects of wear and tear on PFAS levels in firefighter gear. Moreover, collaborations among federal partners and research institutions seek to establish updated standards and protective measures to safeguard firefighters from potential PFAS-related health hazards.
Frequently Asked Questions
Explore key questions surrounding PFAS (Per- and polyfluoroalkyl substances) and their presence in firefighter gear, along with the heightened health risks associated with these chemicals.
What are PFAS?
PFAS (Per- and polyfluoroalkyl substances) are a large group of more than 10,000 synthetic chemicals not found in nature. Their strong, long-lasting carbon-fluorine bonds make them difficult to degrade, hence PFAS are often referred to as “forever chemicals.”
Why does turnout gear contain PFAS?
PFAS are used as a durable water repellent (DWR) finish / coating applied to provide water and oil repellency in accordance with National Fire Protection Association’s 1971 Standards. It is a major component of the moisture barrier within turnout gear.
What are the increased health risks from PFAS exposure?
Studies link PFAS exposure to the development of cancer, and other health effects related to: behavioral development, metabolism, and the circulatory, digestive, endocrine, immune, neurological, and reproductive systems.
