2.8.1 Fire Department Notification
It  is  recommended  that  the  magnet  operator  introduce  the  fire  department  and/or  local
authorities  to  the  magnet  site.  It  is  important  that  these  organizations  be  informed  of  the
potential  risks  of  the  magnet  system,  e.g.  that  much  of  the  magnetic  rescue  equipment
(oxygen-cylinders,  fire  extinguishers,    axe's  etc.)  can  be  hazardous  close  to  the  magnet
system.  In  addition,  their  expertise  and  experience  can  be  invaluable  in  creating  an
Emergency plan.
• In a NMR laboratory use only non-magnetic fire extinguishers.
• Breathing equipment which uses oxygen tanks made out of magnetic material can be life
threatening when used close to a magnet system which is energized.
• During a quench helium gas escaping from the system must not be mistaken for smoke.
Instruct the fire department and technical service not to „extinguish“ the magnet system
with water. The outlet valves could freeze over the quench valves eventually do not close
again.
• Laboratory windows which are accessible during an emergency must be clearly marked
with warning signs, visible from the outside.
