Cargo on Ship That Hit Baltimore Bridge Included Some Hazardous Materials

The cargo ship that caused the Baltimore bridge collapse was carrying hazardous materials, the National Transportation Safety Board said.

NTSB Chair Jennifer Homendy said there are 56 containers aboard containing hazardous materials, including corrosives, flammables and lithium ion batteries.

She said some containers were breached and a sheen was identified in the water that will be dealt with by authorities. She said the voyage data recorder has been recovered.

Homendy said the investigation could take 12 to 24 months but that the NTSB will not hesitate to issue urgent safety recommendations during that time. She said a preliminary report should be released in two to four weeks.

“It’s a massive undertaking for an investigation,” Homendy said. “It’s a very tragic event.”
