Liquid nitrogen provides temperature as low as -196°C. If liquid nitrogen is directly handled,
frostbites, loss of sight, and others are foreseen. Always wear leather gloves, goggles, trousers
without turnips, etc. to handle liquid nitrogen. In addition, use cautions to liquid nitrogen transport
lines, too. In this unit, there is a part with danger of burns if touched directly. Perform work such as
maintenance or repair at least 30 minutes after the unit is shutdown.
High-pressure helium gas is filled in this unit. When disassembling or disposing of the unit or parts, be
sure to discharge helium (no need to discharge helium for regular maintenance). In addition, never
attempt to install the apparatus under the atmosphere of hydrochloric acid-based, chlorine gas-based,
and other corrosive gases.
