Fireworks Explode at NH Home, Injuring 9

July 4th is a day that many families celebrate with fireworks, sparklers, BBQs and a plethora of other related activities. While it's a fun-filled time of remembrance and appreciation for the United States' founding, a few of the aforementioned activities must be approached with care, as dangers are more than possible. This was evidenced on Tuesday night, in Pelham, New Hampshire, when nine people were injured after fireworks allegedly exploded inside of a home.

Right now, details are still coming in, but the resulting explosion was put out by firefighters who arrived at the scene around 7:30 p.m. Among those injured were three children -- two of whom were transported by helicopter to Boston hospitals following the incident. Five others were taken by ambulance for local treatment. Police claim that "a large amount of fireworks were located in and around the home."

WMUR-TV in Manchester reported that the fireworks ignited on the home's back deck. The outlet continues with more details:

"The extent of their injuries was moderate to minor, and the two pediatrics were severe," said Pelham Fire Chief James Midgley.

The ensuing fire damaged the back of the home. Fire officials said it was unclear if the group planned to set off the fireworks Tuesday or if the fireworks somehow caught on fire.

"From what we understand, there were fireworks on the back deck and they somehow ignited," Midgley said.

Neighbor Richard Souza, who lives on a street behind the home in Pelham, a town of about 13,000 residents an hour drive south of Concord, said the people who live in the home set off fireworks every year for July Fourth.

He said there seemed to be a lot of fireworks going off Tuesday night and soon after fire trucks roared into the neighborhood and firefighters turned their hoses on the home.

"It sounded like they were squirting the house down," Souza said.

"I heard -- it sounded like a million gunshots, and I thought maybe they were testing it, and then I saw the huge mushroom cloud and I was like, 'Oh man, that can't be good,'" added neighbor Taylor Jackson.

The adults' injuries are described as moderate to minor, while the two children, authorities say, sustained severe injuries.
