Danger from Strong Magnetic Fields
The magnets housed in the NMR facility have magnetic field strengths of 9.4 Tesla and 14.1 Tesla, approximately 2000 times the strength of typical fridge magnet. To avoid damaging the equipment, injury and possible death, the following safety rules must be followed:
Danger of, and from, a Magnet Quench If a magnetic material is brought within 5 feet of the magnet, it may be drawn to the magnet with great force, possibly causing the magnet to quench. A magnet quench releases hundreds of litres of nitrogen and helium into the air that could potentially result in asphyxiation. If a quench occurs, evacuate the room immediately. In Case of Fire In case of fire, the alarm near the entrance doors will flash and the siren will sound. The evacuation route depends on the where the fire resides:
In Case of Medical Emergency In case of medical emergency, use the phone in the NMR facility to call 911. |
