STONEHAM — Chief Matthew Grafton reports that the Stoneham Fire Department responded Wednesday to a Hazmat incident in a Main Street business.
On Wednesday, Sept. 18, at approximately 1:18 p.m., the Stoneham Fire Department was called to LA Fitness, 121 Main St., for a report of a haze coming out of a rooftop HVAC unit.
Firefighters sounded the building’s fire alarms to evacuate the building. The Stoneham Fire Department ladder truck is out of service due to mechanical issues, so the Woburn Fire Department sent a ladder truck to assist. Firefighters were able to shut down the rooftop HVAC unit and declared a Tier 1 Hazmat.
The gas emitted by the HVAC unit is believed to be freon, but a regional state Hazmat team is responding to the incident to identify the gas conclusively and confirm that it is safe.
Firefighters from Woburn and Reading covered Stoneham’s fire station while companies responded to this incident.
