Fireworks are dangerous. Even the professionals can have problems. Last night in Simi Valley California a wooden platform holding the pyrotechnics tipped over. This sent live rounds of fireworks in the direction of the Independence Day crowd that had gathered to see them.

Between 8,000 to 10,000 spectators had gathered for the event when the incident happened. Four people were listed in serious condition, but their injuries were not life-threatening. Another 16 were taken to area hospitals with minor to moderate injuries. The remainder were treated at the park where emergency crew, already on hand as a safety precaution, set up a triage area.
