Epoxy creep' factor in Big Dig death
'Epoxy creep' factor in Big Dig death - Yahoo! Newsfatal Big Dig tunnel collapse in Boston could have been avoided if authorities had considered that the epoxy securing tons of ceiling panels could slowly pull away, federal investigators concluded Tuesday.
ADVERTISEMENTThe National Transportation Safety Board approved a report saying the likely cause of the accident that killed a woman was "use of an epoxy anchor adhesive with poor creep resistance" that could not sustain long-term loads.
The board, meeting on the first anniversary of the accident, also issued a series of recommendations, including creation of mandatory tunnel inspection programs similar to those required for bridges and the development of protocols to test adhesive anchors used to hold tunnel ceiling panels.
Milena Del Valle, 39, was crushed to death on July 10, 2006, when 12 tons of concrete ceiling panels fell from the roof of the Interstate 90 connector tunnel as she and her husband drove toward Logan Airport.
