Excerpts from FireRescue1.com:
Cancer awareness in the fire service has never been higher. Recent studies have highlighted a troubling trend: firefighters are developing certain types of cancer at younger ages, prompting a renewed focus on hygiene practices after fires. One key area of concern is the cleaning of turnout gear, which can remain contaminated with carcinogens if not properly maintained.
Turnout clothing is often exposed to dangerous chemicals during structure fires, and unless it’s cleaned thoroughly, these substances can linger. However, many fire departments still struggle with regular cleaning routines. Even those with multiple sets of gear often lack the resources or infrastructure to clean them as frequently as needed.
To address this, new decontamination procedures are being introduced, such as cleaning gear outside the fireground to prevent contamination from spreading to vehicles, stations, or personal belongings. These steps are crucial for reducing long-term exposure risks.
The fire service has made progress over the past few decades, especially with the development of NFPA 1851, which outlines guidelines for the care and maintenance of protective gear. Early efforts by organizations like FIERO, NAFER, CAFER, and SAFER helped shape these standards. However, despite advances in washing technology and new cleaning methods—like ozone treatment or CO2-based dry cleaning—there hasn’t been much progress in updating the standard itself.
A major challenge remains: how to measure whether cleaning is actually effective. The Fire Protection Research Foundation recently launched a project to develop reliable methods for testing whether harmful contaminants are truly removed from turnout gear. This isn’t just a science experiment—it's a complex issue because every fire produces different chemical mixtures, making it hard to create a universal test.
Sampling is another hurdle. Contaminants aren’t evenly distributed across gear, so labs must decide where to take samples. Current methods used for soil or water analysis don’t always work well for turnout clothing. The foundation’s new project aims to simulate real-world fire conditions in the lab, using controlled contamination to evaluate cleaning effectiveness accurately.
If successful, this research could lead to better cleaning protocols, helping firefighters avoid long-term health risks. But there’s a catch: more frequent cleaning can also damage gear faster, reducing its lifespan and performance. So, any new cleaning method must be both effective and gentle on the equipment.
While keeping turnout gear clean is important, it’s just one part of the puzzle. Firefighters face carcinogen exposure in many ways, but improving hygiene practices is a critical step forward. With continued research and better standards, the fire service can move closer to safer, healthier working conditions for all.
