A bipartisan group of nearly 100 Massachusetts lawmakers is calling on Attorney General Andrea Campbell to join a lawsuit against manufacturers of firefighting equipment made with toxic chemicals known as PFAS.

The lawsuit is led by ten Worcester firefighters and claims firefighting turnout gear manufacturers sell their products to governments and fire departments despite knowing the extreme health dangers of PFAS exposure.

The group, led by state Sen. Michael Moore, D-Worcester, and state Rep. Jim Hawkins, D-2^nd Bristol, sent a letter to Campbell advocating for protective firefighting gear to not be made with these chemicals.

“For years, we’ve always thought that any exposure or cancer resulting from exposure was probably due to the chemicals that they dealt with when they were responding to the fire,” Moore said. “Now that we know PFAS, which is a known carcinogen, is actually in the fire suppression foam and it’s also used on the turnout gear they wear when trying to protect themselves from the fire.”

The letter also asks the AG’s office to open an investigation into whether the sales of this turnout gear violates the state's laws against unfair and deceptive trade practices.

In 2022, then-Attorney General Maura Healey’s office sued PFAS manufacturers for violating Massachusetts law protecting drinking water and other consumer protection statutes by selling PFAS-containing firefighting foam to cities and towns across the state.
