Major fines issued after Esparto fireworks blast that killed seven workers in July

California workplace safety officials have issued 15 citations totaling more than $200,000 against Devastating Pyrotechnics after the deadly July 1 fireworks explosion in Esparto. Cal/OSHA says the company failed to train workers for emergencies and fire hazards. Seven people were killed and two others injured in the blast, which destroyed buildings and damaged nearby homes. Regulators say their focus now is ensuring proper protections to prevent another tragedy. A criminal investigation into the blast remains ongoing, and the company has not responded to requests for comment.
