Hi,
I had someone get a metal chair stuck to the base of a 500 mhz magnet
last year. It took 3 people and a few 2x4's to break it away slowly. No
quench. Lucky. Field came back and is stable.
We did have some notices posted on the doors and the magnet. However
the cleaning person couldnt speak English nor able to read much of it
let alone technical terms.
Since then I have warnings posted in several languages. ie; JAK
MAGNET!,etc/
