Thirteen people were injured after a container ship at the Port of Long Beach leaked a chemical substance on Sunday morning, the United States Coast Guard said.
Twelve dockworkers suffered minor injuries after being exposed to the leaked substance propyl acetate, the Coast Guard said. A firefighter was also injured due to a fall, the agency added.
The incident occurred around 9:27 a.m. and was first described as an unidentified substance leakage, in a tweet from the Long Beach Fire Department.
The Coast Guard later identified the substance as propyl acetate, which can cause serious eye irritation and eye damage as well as dizziness or drowsiness, according to the National Institute of Health.
One of the injured dockworkers and the injured firefighter were both transported to Long Beach Memorial Medical Center for treatment, the Coast Guard said.
Propyl acetate had spilled from a commercial container ship called Harbour Bridge, which was docked at Pier G in the Port of Long Beach, the agency added.
A 1,000-foot boom perimeter has been established as a precautionary measure to protect the environment and Long Beach Fire rescue boats area assisting in the operation, authorities said.
Meanwhile, the container has been removed from the ship, authorities said.
A safety zone of 150 feet has been placed around the container ship while emergency personnel respond to the spill and assess it, the Coast Guard said.
The hazmat team from the Long Beach Fire Department and members of Patriot Environmental Laboratory Services are cleaning up the spill, the agency added.
