The real sad cases are the "ill-trained" variety. Around here, a lot of
construction help is day labor. There's street corners where guys looking
for work hang out. You need three pairs of hands for a day, you drive by
with your truck, hold up three fingers, and three guys jump in.

You stick a tool in the guy's hand and show him where the trigger is.
Safety training probably consists of "Be careful, this thing can hurt you".
