“Fugitive” natural gas and an error by local authorities were behind the April 17, 2017 explosion that destroyed a home in Colorado and killed two people. Those findings are from a brief recently released by the National Transportation Safety Board (NTSB), which investigated the incident at the Firestone residence.
The homeowner and a plumber who was working at the house died in the explosion, and two other residents were injured. At the time of the explosion, the fatally injured resident and plumber were replacing a water heater in the basement.
