Great Barrington, MA - Great Barrington firefighters quickly contained a fully involved garage fire on Cottage Street that involved a significant quantity of chlorine and other pool chemicals, prompting a precautionary hazardous materials response.

Crews arrived within minutes to find the garage heavily involved and immediately stretched a handline, knocking down the bulk of the fire using tank water before securing a hydrant supply. Due to exposure concerns and limited initial staffing, a first alarm was requested.

During suppression, firefighters identified hazardous pool chemicals inside and around the structure, leading to the notification of state environmental and HazMat teams. As a precaution, nearby residents were advised to remain indoors and close windows. Upon evaluation, conditions were deemed stable and the HazMat response was scaled back.

The fire was brought under control in about 20 minutes, with crews remaining on scene to monitor for any environmental impact and check nearby homes for potential hazards.

Mutual aid departments assisted at the scene, while additional units covered the district. No injuries were reported and no other structures were damaged. The cause of the fire remains under investigation and is not considered suspicious.
