STOUGHTON, Wis. -- A man has been hospitalized following an explosion at a Stoughton home Tuesday night.

Investigators said that fireworks were responsible for the explosion at the home in the 1100 block of Sundt Lane at about 6:30 p.m.

Stoughton police said that adjacent residences were asked to evacuate Tuesday night.

Smoke emerged from the home Tuesday night and the smell of sulfur around the home was apparent, WISC-TV reported. The explosion pushed out the entire sliding door to the back patio.

Stoughton police said the preliminary investigation revealed that Christopher B. Hansen, 23, was in his basement when an explosion occurred, causing burns to his body. He was able to walk out of the home, which was filled with smoke.

Witnesses said that after hearing the explosion, several neighbors tended to Hansen after he escaped from the home.

"I thought I better open the patio door and I heard a man come out screaming, 'Help me; help me.' And the smoke just intensified so much. And then all of sudden there were a rush of neighbors all over. And the window had already blown out at that point," said neighbor Linda Pederson.

Officials said Hansen was transported by Med Flight to the UW Hospital and Clinics Burn Center and is being treated for burns on his arms, legs and face. Hansen is listed in serious condition, WISC-TV reported.

Authorities said Hansen was alone in the residence at the time of the explosion.

Stoughton police said Hazmat crews are at the scene Wednesday cleaning up from the explosion.

Police said Hansen makes fireworks as a hobby and there were lots of explosives and chemicals in the basement.

"What we understand from statements that were made is that he was in the process of making, in layman's terms, probably a homemade gun powder when it ignited and apparently caused the explosion," said Stoughton Police Chief Greg Leck. "These were significant-sized fireworks to the extent of city-sized displays and whatnot. This wasn't just simple bottle rockets."

Stoughton police said they are being assisted in the investigation by the Stoughton Fire Department, the Dane County Sheriff's Office Bomb Squad and the Federal Alcohol Tobacco and Firearms Division.

Police said this is just the second investigation involving a house fire caused by fireworks in Wisconsin in the past few years.

Police said it's possible that Hansen could face criminal charges.
