We need some of these, along with locks left open, to be publicly accessible but without publicly accessible keys. The idea being unsafe equipment can be unplugged and the plug locked in one of these cages. Difficulty though is we have a mix of common 125VAC plugs, and L5 / L6 /L21 twist locks of various amperages. But there lockout cages for twist locks and there may be one size that fits all out twist locks.
The Sawstop has a rotating power disconnect that you can padlock if needed.
In the past, I did bring in cord lockouts, and some brass-and-steel unikey luggage locks from the dollar store. At the time, people were emphasizing “it’s a volunteer do-ocracy, just do it” and someone worked on the equipment without talking to me at all. That involved cutting off the lock and the reusable lockouts were apparently just thrown out. Well they did fix the equipment on a volunteer basis, I don’t want to minimalize the bottom line, but that’s how it went over in the past.
