Blast kills worker at refinery owned by Chilean state oil company

SANTIAGO, Chile—An explosion at a refinery owned by Chile’s state oil company ENAP has killed one worker.

ENAP says contractor Francisco Segundo Suarez Sandoval died in the blast while performing maintenance with other workers.

The company said the explosion at Aconcagua refinery was caused by a sulfuric acid leak inside the refinery’s hydrogen plant.

At least three people were taken to hospitals with injuries.

ENAP says the refinery has started an investigation into the accident.
