Frozen hydrants hampered Boston firefighters as they responded to a pair of house fires in Dorchester amid frigid temperatures on Friday and Saturday.
Sixteen people and three pets were displaced after a multi-family home at 110 Fuller St. caught fire Saturday at about 1:30 p.m., the Boston Fire Department said in a tweet.
The department posted a video showing a fierce blaze erupting from the back porch, sending black and white smoke into the air.
“This is what first due companies responding to 110 Fuller St. were facing before meeting frozen hydrants,” the department’s tweet said. “BFD motor squad did a great job heating hydrants quickly for companies.”
The fire department posted an update at 3:59 p.m. that crews had been cleared from the scene.
One firefighter suffered minor injuries and was transported by Boston EMS, the fire department said.
The Red Cross of Massachusetts is assisting those displaced, and the MBTA provided a bus to keep the residents warm as firefighters worked to contain the blaze.
Late Friday night, four people and one dog were displaced after a home caught fire . Firefighters struggled to extinguish the flames as they encountered multiple frozen hydrants, the fire department said in a tweet.
The department responded to the 2-alarm fire at the single-family home on 9 Roach St. at around 11:45 p.m. Companies encountered the frozen hydrants upon arrival, according to the department.
“Thankfully no injuries with ice being everywhere,” the department said in a tweet.
Damages were estimated at around $150,000.
The department thanked the Boston Sparks Association, Boston EMS, and the Boston Police Department for their collaboration in efforts “to stay warm, keep safe, and [steer] traffic around our waterlines while rushing to find unfrozen hydrants.”
Temperatures Friday night into early Saturday morning when firefighters still battled the blaze were a frigid 11 degrees. The temperature dropped to 8 degrees by 8 a.m. Saturday and climbed to 20 degrees by about 3 p.m., according to the National Weather Service.
