Utah Occupational Safety and Health Administration employees will reinforce a policy regarding operators' duties and responsibilities in the initial stages of fire emergencies at Chevron U.S.A. Inc.'s Salt Lake refinery.

The reinforcement is part of an agreement the U.S. Department of Labor obtained from the company for alleged violations of federal safety regulations at the company's Richmond, Calif., refinery following an OSHA investigation of a fire and explosion April 10, 1989, when three employees were burned.Douglas J. McVey, director of the State Industrial Commission's OSHA Division, said although he hadn't heard about the department's action, it will be his office reinforcing the policy because in Utah OSHA is administered at the state level.

Department officials announced the company had been fined $275,000 in a settlement agreement that followed issuance of citations for alleged violations of federal workplace rules. The company was cited for 109 alleged willful violations and five alleged serious violations.

The department agrees to reinforce its policies regarding operators' duties and responsibilities during emergencies and after fires start.

Also, flame resistant clothing will be provided to and worn by all employees working in designated mandatory areas and the company will require the use of standard firefighting clothing when employees are required to remain in the area during the post-incipient stage of fires.
