BAKERSFIELD, Calif. --
A man cleaning a tanker truck passed out due to low levels of oxygen, fire crews said.
The Kern County Fire Department said that about 1:20 p.m. on Wednesday, a call was received about an unconscious man inside a tank in the 7100 block of Golden State Highway.
Crews said a man was found unconscious inside a tanker trailer carrying residual crude oil.
The man had been cleaning the tank with a citrus chemical when a coworker noticed him unconscious, according to the KCFD.
Crews immediately began to monitor the air within the tank for potential hazards prior to making entry.
An air system was placed inside the tank after determining high levels of flammable vapors and low levels of oxygen.
A rescue team was set up and began to make entry after the levels were determined to be safe for rescue efforts, at which time the man was able to make his way to the ladder for extrication, the KCFD reported.
Crews escorted the man down from the tank. After decontamination, he was evaluated and transported to the hospital.
