DERRY — A downed power line caused a two-alarm brush fire, destroying a utility's metering shed and threatening a house Thursday on By-Pass 28.
Firefighters were called to the area shortly after 11 a.m., fire Battalion Chief Michael Doyle said.
Nobody was injured in the blaze, but the fire came within several feet of a house at 67 By-Pass 28.
The fire burned about a quarter-acre, Doyle said. Firefighters had it knocked down shortly before noon.
The recent weather conditions have kept area firefighters busy fighting brush fires. There were fires in Hampstead, Kingston and Auburn Wednesday. An exterior fire in Derry Tuesday evening spread to the rear wall and deck of a home on Faith Drive.
Derry firefighters helped open the Warner Hill fire Tower Tuesday, a site critical to spotting and reporting brush fires.
No permitted burning was allowed in Derry Wednesday or Thursday, Doyle said. Wednesday was a red flag day and Thursday was a Class-3 risk day.
That's the third highest level of risk, according to the N.H. Division of Forestry and Lands.
Derry firefighters are warning residents to pay attention to anything flammable and follow outdoor fire regulations.
Between the warm weather and dry ground, Doyle said, brush fires are more likely.
"Nothing's greened up yet," he said. "Everything's still brown."
Workers cutting trees in the area may have caused the downed power line, which started the fire, he said.
There were no difficulties in battling the blaze, Doyle said, save for the fact some Derry firefighters were busy.
"We only had one company that was available," he said at the scene of the fire.
Four engines, two tankers, and two forestry units were among the Derry units that responded.
Two ambulances and a fire engine were already on other calls, Doyle said. Derry had to call in mutual aid.
Londonderry and Hooksett provided assistance at the scene. Firefighters from Hudson, Plaistow, Salem and Chester provided station coverage.
Firefighters sprayed foam, ensuring nothing reignited.
Eversource employees were working on nearby power lines.
"They very quickly made it safe," Eversource spokesman Martin Murray said.
The utility's metering shed was destroyed, Murray said. Metering sheds measure the amount of electricity passing through a single point.
"There's no customer impact," Murray said.
The process to replace the shed could start as early as Friday morning, he said.
"We're able to carry on with business with usual," he said, "and it is completely safe there."
