VIDEOS: Three firefighters were injured, one seriously, after a natural gas explosion led to a fire Monday at a commercial building on Amherst Street in Nashua.

Officials said none of the injuries were considered to be life-threatening.

One firefighter was released from the hospital, while the other two remained hospitalized overnight.

The fire happened at the Greater Nashua Mental Health building at 440 Amherst St.

About 40 people were working inside when a ruptured natural gas line was reported around 2:15 p.m., according to fire officials.

Nashua Fire Chief Steve Buxton said workers evacuated after smelling gas and hearing a hissing sound.

Investigators believe no one was inside when the building caught fire. Fire Marshal Sean Toomey said there was no active fire when crews arrived to investigate the reported gas leak.

Some firefighters became trapped for a short time after a small explosion, but were able to get out.

A new study published in the Journal of Occupational and Environmental Medicine has identified clear occupational factors and demographic indicators associated with elevated serum levels of per- and polyfluoroalkyl substances among U.S. career firefighters.

This research from University of Arizona and Arizona State University researchers, based on data from the Fire Fighter Cancer Cohort Study, provides vital insights into the factors that influence PFAS body burdens in this essential workforce.

Understanding the predictors of PFAS accumulation is a critical step toward protecting their long-term health.

The study shows that fireground practices and departmental protocols significantly influenced PFAS levels, with certain routines related to handling contaminated equipment and personal protective gear associated with higher blood serum concentrations.

Demographics and lifestyle characteristics, such as years of service, rank or role within the fire service, and personal behaviors, also predicted PFAS levels.

These findings highlight that both workplace and personal factors contribute to overall chemical exposure.

This evidence suggests that modifications in decontamination procedures, gear storage practices and routine operational policies may reduce exposure to PFAS among firefighters.

It was a chance for an up-close look by reporters as Broward Sheriff Fire Rescue (BSFR) begins deployments of the two highly-sophisticated fire and air rescue helicopters for operational missions.

The media preview marks a new chapter for BSFR following the tragic crash in September 2023 in nearby Old Pompano, killing BSFR Captain Terryson Jackson, and a resident on the ground, Lurean Wheaton.

BSO took delivery of the helicopters, which cost roughly $15 million a piece, in December 2024 and May 2025. Since then, BSFR crews have been undergoing specialized training in airborne firefighting and rescue operations.

BSO officials said one of the capabilities of the new helos – unavailable in the agency’s older craft – are their powerful lifting capacity.
