In a statement, Cohasset Fire Chief Robert Silvia and State Fire Marshal Peter Ostroskey said the fire at 147 South Main St. began in one of the shop’s repair bays, where a mechanic had made welding repairs earlier in the day. The shop’s owner tried to extinguish the fire himself, but oil and gas inside the shop allowed the fire to spread quickly through the entire building.
Firefighters from at least eight South Shore towns worked to extinguish the blaze. The Cohasset fire and police departments worked with State Police and the state fire marshal’s office to investigate the cause of the fire.
No one was injured, but the garage, which town records indicate was built in the 1930s, is deemed a total loss. Damages are estimated at $300,000. A car and a farm tractor that were inside the shop were also both destroyed, Assistant Chief John Dockray said.
On the morning of April 5, state environmental officials remained on the scene to monitor run-off water that was contaminated with oil from the garage. Dockray said the town’s drinking water supply was not at risk.
Dockray said firefighters were alerted to the blaze about 4:20 p.m. after someone working on a car outside the garage noticed smoke and called 911. He said no one was in the garage when the fire broke out and a person who lives on the second floor was not home at the time.
Dockray said ammunition was kept in the garage, but the flames did not reach it.
The two-story garage is across the street from St. Anthony Parish and had one residential unit on the second floor. It was built around 1935 and was last assessed at $533,300, including the value of the land, according to town records.
