LIQUID NITROGEN SAFETY:
These liquid nitrogen generators have been designed with the
highest level of user safety in mind. They are also designed to minimize direct handling
of Liquid Nitrogen by the user. However care must be taken to ensure no contact is
made with the cryogenic fluid during Liquid Nitrogen removal from a leak or splash.
HANDLING:
Never allow any unprotected part of the body to touch un-insulated pipes or
vessels which contain cryogenic fluids. The extremely cold fluid can cause severe burns
if even momentary contact with human skin is made. Always wear adequate eye
protection and gloves when handling cryogens.
CONTAINMENT:
Never carry Liquid Nitrogen in a vessel not properly suited for Cryogenic
Fluids. MMR assumes no liability for injuries caused through improper handling or use
of the provided Cryogen Storage Vessels. MMR have thoroughly tested and approved
the following Cryogenic Storage Vessels for use with this system:
Brymill CRY-AC® Series for cryosurgery.
MVE Dewar’s from PrincetonCryo.
RISK OF EXPLOSION
: NEVER CAP OR SEAL A STORAGE VESSEL FOR LIQUID
NITROGEN THAT DOES NOT HAVE ADEQUATE VENTILATION HOLES OR A PRESSURE RELIEF
DEVICE.
SPECIFICATIONS:
Liquid Nitrogen is a colorless, odorless, extremely cold liquid and gas
(-198°C). It can cause rapid suffocation when concentrations are sufficient to reduce
oxygen levels below 19.5%. Contact with liquid or cold vapors can cause severe
frostbite. Cold vapors in the air will appear as a white fog due to condensation of
moisture. While this may indicate the presence of the gas it should not be used to
determine its concentration in the atmosphere. Oxygen concentrations must be
monitored in the release area. All cryogenic liquids produce large volumes of gas when
they vaporize. One volume of Liquid Nitrogen will expand to produce 696.5 equivalent
volumes of gas.
