ELECTRICAL SHUTOFF SECURING ELECTRICITY DOES NOT
DE-ENERGIZE THE MAGNET!!!!!!!!

HEILUM GAS In the event the magnet has been
quenched, the helium gas will be vented into the atmosphere, with an approx 500-1 expansion rate
Only a hazard in vented into a closed space (O2 displacement)
Will produce a HUGE white vapor cloud

QUENCHING Quenching refers to the emergency
dumping of Helium gas to de-energize the magnet
Can only be done from INSIDE the room where the magnet is
CANNOT be done by a firefighter wearing protective gear or anything metallic

The “Line in the Sand” No personnel wearing anything metallic can
cross this line Very strong magnetic field emanating 6 ‘ in
all directions from the magnet, 24/7/365 Any firefighting has to be done from beyond
this line
