3M, DuPont to Face Firefighter Lawsuit Over 'Forever Chemicals' in Gear

A U.S. federal judge has ruled that industrial giants 3M, DuPont, and Honeywell must face a lawsuit from Connecticut firefighters who allege their protective gear was contaminated with toxic "forever chemicals," exposing them to a heightened risk of cancer.

The decision allows a proposed class-action lawsuit, reportedly the first to exclusively target firefighter gear containing these substances, to move forward, adding to the legal challenges facing the chemical manufacturers.

Court Allows Lawsuit to Proceed

U.S. District Judge Alvin Thompson in Hartford, Connecticut, on Tuesday denied a motion by more than 20 defendants to dismiss the case, as reported by Reuters. The lawsuit was brought by 13 firefighter union organizations and 12 individual firefighters.

The court found that the unions have the organizational standing to sue and that individual firefighters can seek damages and medical monitoring even if they do not currently have symptoms of cancer. The judge also determined that the plaintiffs had sufficiently alleged that 3M, a major manufacturer of PFAS, had a duty to warn about the chemicals' risks and was negligent.

The Lawsuit's Allegations

Ad

The complaint alleges that per- and polyfluoroalkyl substances, or PFAS, leached from the firefighters' protective "turnout gear" through skin absorption, ingestion, and inhalation. Specific materials cited in the complaint as containing PFAS include 3M’s Scotchlite reflective material and DuPont’s Kevlar.

In seeking to dismiss the case, defendants argued there was no allegation that the gear "failed to serve its function of protecting firefighters from the hazards of fighting fires." Lawyers for the plaintiffs called the ruling significant for establishing that prolonged exposure from turnout gear justified legal standing.

Context and Investor Impact

PFAS are known as 'forever chemicals' because they do not easily break down in the environment or the human body. This case represents another front in the expanding litigation over the chemicals' impact, creating further legal and financial uncertainty for the companies involved, including DuPont spinoffs Chemours and Corteva.

This lawsuit follows major previous settlements related to PFAS. In 2023, 3M, DuPont, and two other companies reached agreements totaling more than $11 billion to resolve claims that their PFAS-containing firefighting foam had polluted public drinking water supplies, though they did not admit wrongdoing.
