I'd regard that machine as "unsafe to be connected to the mains",
PLACARD it with a notice to that effect, pull the plug, and *PADLOCK* it
so that it _cannot_ "accidentally" be plugged in. If the plug has holes
in the blades, a little lock through one of those holes works. If not,
"something more creative" is called for.

DAGS for lockout tagout to turn up links for suppliers. We have this stuff
all over the labs here at work and yes, it is used.
