Four people were hospitalized Thursday morning after they were exposed to leaking gases at a refinery in Wilmington.
One of the workers was in serious condition. One worker was lowered from a raised platform to the ground by a stretcher and rope system. Firefighters reached the platform by using a ladder truck.
Firefighters responded to the refinery in the community west of Long Beach just after 6:30 a.m. after a report of leaking butane and hydrogen sulfide, the LAFD said.
Crews shut off the leak. No evacuations were ordered in nearby neighborhoods.
