My certification has lapsed and this thread just reminded me to renew it. Not sure if that count towards your 100 but definitely still a good thing.
I work in a hospital, we are all CPR & AED trained.
I've expired since I left LE. I really should find a class and re-up.
Have often thought that having an AED on hand would probably be a good idea here at the shop, given the whole high voltage thing.
Was overwhelmed with choices last time I looked though.
