A senior hazmat investigator from the National Transportation Safety Board looked at the cargo and ship's manifest, identifying 56 containers of hazardous material, agency Chair Jennifer Homendy said Wednesday.
"He was able to identify 56 containers of hazardous materials. That's 764 tons of hazardous materials — mostly corrosives, flammables, and some miscellaneous hazardous materials, class nine hazardous materials, which would include lithium ion batteries," she said at a news briefing.
Some of the hazmat containers "were breached," she said, adding that sheen was seen on the waterway.
