NEW DETAILS: Workers' conditions in Peosta house explosion

Posted: Updated:

PEOSTA (KWWL) -- One worker's father said all three men are in critical but stable condition as of Wednesday afternoon.

The Dubuque County Sheriff's Department released the names of the men who were inside a rural Peosta home when it exploded Tuesday morning.

Sheriff officials in Dubuque County say 18-year-old Brad Mahoney of Dyersville and brothers 28-year-old Adam Conrad and 24-year-old Scott Conrad, both of Delhi, were installing new flooring in the basement of the Peosta home when an explosion occurred in the basement just before noon Tuesday.

The three men were flown to the burn unit at University of Iowa Hospital.

"They're all three in critical condition but stable," Brad Mahoney's father Randy said. "They were cleaning the floor, apparently, and the fumes built up and something sparked."

The Dubuque County Sheriff's Department said investigators think fumes from chemicals used in basement construction ignited, causing the explosion. Exactly what sparked the fumes, investigators are still trying to find out.

Regardless of the cause, the explosion left the three workers with significant third-degree burns.

"Brad was over 50 percent, Scott was over 60 percent and Adam was over 70 percent," Randy Mahoney said. "All three of them got it to the face."

Homeowner Angela Hatcher and her three children living in the home got out safely. One firefighter was treated and released for heat exhaustion.

Ed Heiderscheit is a neighbor of the Hatchers. He said spoke with homeowner Tim Hatcher Wednesday morning.

"Tim was taking it good," Heiderscheit said. "The kids, they're all doing fine."

Heiderscheit said the Hatchers were staying in a local motel.
