The California agency that investigates workplace accidents has cited and fined ExxonMobil more than $560,000 dollars for workplace safety and health violations following a probe into February's explosion at a Los Angeles-area refinery.
The California Division of Occupational Safety and Health said Thursday that 18 of the 19 citations are classified as serious because violations could potentially cause serious injury or death. Six of those serious violations were also classified as willful because Cal-OSHA found that Exxon did not take action to eliminate known hazardous conditions at the refinery.
ExxonMobil says it's reviewing the citations.
The blast in Torrance slightly injured four contractors, heavily damaged equipment and rained a fine white ash on nearby homes and cars.
Cal-OSHA says the explosion was caused by vapor leakage.
