Yeah, yeah, we all love the good ol' nanny-like CPSC and all the wonderful things they do in looking out for our best interests. But they also publish an interesting annual summary of fireworking accidents involving 1.3, 1.4, and "unspecified/homemade". Some of the characters described are definitely candidates for the Darwin Award.
Apart from number of injuries (reported) and ER visits due to fireworks accidents, they also give breakdowns of device types, victim demographics, and in some instances detailed descriptions of the events. This is fiscal year 2018's report--couldn't locate one for 2019 if it's been published yet.
Interesting to me; perhaps to you, too...
