OSHA has cited a Texas oil refinery with an alleged willful and 29 alleged serious violations after a fire and explosion claimed the lives of two workers and injured three others.

OSHA's Dallas Area Office began its investigation on November 20 at the company's facility. Flammable vapors were ignited after a Naphtha (flammable liquid) discharge line ruptured at the saturated-gas unit, killing two workers and injuring three others. The investigation found a willful violation for failing to adequately maintain and repair processing equipment.

Serious citations were issued for violations of OSHA's Process Safety Management involving electrical, asbestos, benzene, and portable fire extinguisher standards.

The company which employs about 270 workers is a high conversion, independent refinery with a design crude distillation capacity of about 60,000 barrels per day.

Proposed penalties total $217,350.
