There was a hazmat incident on a ship in the Port of Long Beach (CA) yesterday. It has a couple of interesting issues.
13 workers were injured including one exposed to the vapor from the leaking product.
One of the people injured was a firefighter. (He tripped and fell.)
The substance was propyl acetate. None of the articles I looked at said anything about the size of the leak.
One article said the container held about 6,000 gallons.
