Now there is another new one,ISO/TS 22330:2018 that is fresh off the presses.
I was in a meeting a couple of months ago when some law enforcement officers were saying that they didn't agree with an NFPA Standard for Active Shooter/Hostile Event Response (ASHER) Program , because they could not perform to that standard.
Guess what — if there is a shooting that goes badly, and people get sued, that standard will be used as a ruler that they are measured by. Standards are here to stay and they are not going away anytime soon.
