KEENE -- A city firefighter was injured Friday morning battling a trash fire at the town's transfer station, according to Fire Chief Mark Howard.

The firefighter sustained a back injury at the scene and was treated there, according to Howard. His name and condition were not released.

Firefighters were called to the transfer station on Summit Road after an automatic fire alarm went off about 1:30 a.m., according to Howard.

The crew of Ladder Truck 2 from the West Keene fire station found burning trash in the transfer station and called for backup.

More crews arrived at the scene to battle the flames and keep them from spreading to the recycling side of the transfer station. A line was laid to a firefighting cistern on site, and a back-up supply line was made ready, according to Howard.

Firefighters were able to contain the fire to the 75’ by 50’ trash portion of the building and get it knocked down without it spreading, according to Howard. He estimated damage to the building of about $20,000 and the recycling side required ventilation.

The cause of the fire is not considered suspicious at this time, but anyone with information can call Lt. John Bates at 603-757-1863 or email him at jbates@ci.keene.nh.us
