From the LAT (through archive.is):
At a news conference, Los Angeles Police Chief Michel Moore said officials responding to a home on the 700 block of East 27th Street had found several thousand pounds of illegal fireworks as well as improvised explosive devices that were “more unstable.”
An LAPD bomb squad transferred the improvised devices into the iron chamber of a semitruck that’s meant to contain such explosive material, he said.
Police detonated the devices at 7:37 p.m., believing that the vehicle would be able to contain the explosion, but there was a “total catastrophic failure of that containment vehicle,” Moore said.

At the residence’s patio, officers found several thousand pounds of commercial fireworks stacked 8 to 10 feet high in boxes, and bomb squad personnel spent the day moving them to be stored at another location.
Officers also found improvised explosive devices with simple fuses — about 40 the size of Coke cans and 200 smaller objects of similar construction — and conducted X-rays to determine their contents.
Less than 10 pounds of the devices were transferred into a semitruck, which Moore said was rated, with its outer containment shell, to handle 18 pounds. Officials established a 300-foot perimeter behind the vehicle and evacuated the north and south sides of 27th Street.
According to reports, none of the injuries are “life-threatening”.
FotB RoadRich can correct me if I’m wrong, but I have a memory of APD’s bomb squad telling us (when we were going through the Citizen’s Police Academy) that the most dangerous thing a bomb squad does is…disposal of fireworks. I don’t know if that’s because they do more fireworks disposal than anything else, because people get blasé around them (“It’s just fireworks!”), or if because fireworks are more volatile than anything else they deal with.
Edited to add: Lawrence sent over this tweet from CBS LA: their helicopter was directly overhead when…
