CONCORD, N.H. (AP) -New Hampshire fire officials say at least one man has suffered burns and another was rescued by ladder from a fire at the Concord Steam Corp. heating plant.

Firefighters responded to a fire after 4 p.m. Thursday at the plant, which produces steam to heat downtown Concord businesses, and state and federal offices. It’s on the grounds of New Hampshire State Hospital.

Deputy Police Chief Dan Shapiro said the injured man was burned. The person who had to be rescued by ladder was on a catwalk atop two large silos where the company stores wood chips that it burns to produce the steam.

Witness Heather Fairchild said she was leaving work at the state office of the Department of Health and Human Services when she saw flames shooting out of the wood chip and oil fuel storage building.

She also said she saw a man covered in fuel oil run out of the building.

Fire officials said the man was taken away in an ambulance.

Big I-93 crash still under investigation

DERRY, N.H. (AP) – New Hampshire State police say the investigation of this month’s 59-car pileup on Interstate 93 is a much bigger job than first estimated.

A state trooper is trying to interview more than 100 people involved in the crash to learn what they heard and saw in the moments leading up to the collisions.

The pileup happened between Exits 3 and 4 on Jan. 11, shutting down the northbound stretch for nearly four hours.

Police say there has been no official determination of what or who caused the crash. Between 6 and 8 inches of snow fell beforehand.

It was the first of two pileups in as many weeks for the two-lane highway. On Sunday, eight cars crashed into one another just north of Exit 5 as another 6 inches of snow fell.

The state Department of Transportation has posted electronic letter board signs, warning drivers to slow down on some stretches of the road, even suggesting a lower speed limit. But road data shows many people aren’t paying attention to the warnings.
