Firefighters responded to a fire alarm at Mels Funway Park early Friday morning, encountering smoke and a small fire that was swiftly contained by the building’s sprinkler system.

Engines 1, 4, and Tanker 3 were dispatched to 454 Charles Bancroft Hwy at 3:47 a.m. following the alarm.

The first officer on the scene, a Litchfield Fire lieutenant who lives nearby, reported smoke on the first floor of the three-story building.

A working fire assignment was immediately requested, bringing additional support from Londonderry, Hudson, and Merrimack, including a ladder truck, an engine, an ambulance, and a battalion chief.

Upon the arrival of Litchfield C1, command was established for the incident.

Fire crews meticulously searched the large building for the source of the smoke, a process that took significant time due to the building’s size.

The four occupants of the building were safely evacuated, and all floors were checked.

Light smoke was found on the third floor, but there were no conditions on the second.

The fire, located in a first-floor back laundry room filled with storage items, had been extinguished by the sprinkler system before firefighters arrived.

Once the fire was confirmed to be out, the building was ventilated, air quality was monitored, and the area of the fire was isolated to prevent any further incidents.

The building was then cleared and turned back over to the property representative, allowing all occupants to return.

The cause of the fire is currently under investigation by authorities.

All fire companies involved cleared the scene at 5:30 a.m.
