NTSB investigating pipelines as part of Firestone house explosion

FIRESTONE – The National Transportation Safety Board has joined the local investigators looking into the cause of the home explosion that killed two men in Firestone last month.

The Denver Post reports that the NTSB joined fire, police and Colorado Bureau of Investigation investigators because pipelines are considered a mode of transportation for materials including oil and gas.

Agency spokesman Keith Holloway told the Post in an email Wednesday that the investigators are probing whether there are any safety issues that could have a national policy impact, though results will be slow in coming.

“A typical accident investigation can take 12 to 18 months before a probable cause is determined,” he said.
