The State Fire Marshal’s office says its investigation of a Fourth of July fireworks display accident which injured 28 people in Simi Valley shows that a malfunctioning shell triggered a chain reaction of accidental blasts.
The accident happened during the Rotary Club of Simi Valley’s annual show at Rancho Santa Susana Community Park. The Fire Marshal’s report indicate a five inch, two part shell malfunctioned, blowing up in a mortar tube, leading to an explosion which caused several other blasts.
It sent spectators running in terror, as debris from the fireworks shot into the crowd.
The report says the there was no criminal activity involved, and that the show had all of the proper permits. Ventura County fire officials say they are reviewing the report, and state fireworks policies, to see if additional local protective measures might be warranted.
An investigation into a separate Fourth of July fireworks accident at another professional show, in Ojai, is continuing.
