Examine to understand the cryogenic tank system. It is made up of the cryogenic tank and cylinders and Dewar vessels. The liquefied gas in the tank is under high pressure at a very cold temperature. The gases can be oxygen, nitrogen, helium, hydrogen, argon or carbon dioxide. Usually, the cryogenic tank system has a number of pressure gauges, valves, fittings and connectors that can link to cylinders and Dewar vessels for decanting the cryogenic fluids. The cryogenic tank itself is designed as two tanks in one, an inner and outer tank, with insulation and vacuum between the two tanks.
Get appropriate professional training on managing cryogenic systems. Many health and safety challenges are posed in the handling of cryogenic tanks, cylinders and fluids. Several educational courses have been designed potential users. Courses cover topics like "Connecting regulators and cylinders setup," "How to decant liquid nitrogen" and "Safe manual handling of gas cylinders."
Always wear protective apron and hand-arm gloves. Specially designed cryogenic clothing and gloves must be worn in the operation of cryogenic tank systems. Cryogenic aprons that provide thermal protection up to the lower legs in unfriendly cryogenic environments. Gloves can protect your hands and arms while working with very cold fluid.
Learn cryogenic safety standards. A comprehensive cryogenic safety manual has been prepared by the cryogenic safety committee at Argonne National Laboratory. It lists the key cryogenic safety hazards as cold contact burns, asphyxiation, and explosions due to pressure and chemical contamination. The manual lists many regulatory and technical references that will help one operate a cryogenic system.
