WOODLAND, CA - Hazmat responded to the Pacific Coast Producers plant after a pump malfunctioned and leaked chlorine.
The leak started around 12:30 p.m. Sunday at the plant, located at 1376 Lemen Ave. An exterior pump used to put chlorine in water, which is later sprayed on tomatoes to kill bacteria, released chlorine dioxide into the air.
The Pacific Coast spokeswoman said 40 people were sent to the hospital as a precaution. Employees affected by the leak complained of having headaches.
The spokeswoman said the first shift was sent home and the second shift is expected to be sent home soon. The plant is being inspected to make sure it is safe to return.
Seven AMR ambulances also responded to the scene.
