There are some important safety considerations with which one should be familiar before using an EPR spectrometer. These concern the use of (a) strong magnetic fields, and (b) cryogenic liquids.

  1. People with medical implants (such as cardiac implant pacemakers, aneurysm clips, surgical clips, or prostheses) should check with the EPR Facility Manager before entering the EPR room.
  2. All magnetic objects should be kept away from the magnet at the EPR lab. This includes keys, wallets, mechanical watches, tools, etc. ASSUME THAT ANY PIECE OF METAL IS MAGNETIC UNTIL PROVEN OTHERWISE.
  3. Keep electronics, credit cards, and magnetic storage media outside of the EPR magnet room.
  4. Use only non-magnetic tools near the EPR magnet.
  5. In case a metallic object strikes the magnet, contact EPR Facility staff immediately. Do NOT attempt to pull the object off by yourself.
