Safety Instructions
To this unit, voltage that would cause electrocution or serious injuries is applied. It is extremely
dangerous to touch the live part inside the unit. Make sure to turn OFF the main power source before
performing installation, maintenance or repair. Contacting the internal parts that are not insulated
may damage human body or equipment.
Connect the earth wire to D type grounding.
Nitrogen gas itself is not toxic to human bodies but it reduces the oxygen level in the atmosphere (the
oxygen concentration of 18% or below is defined as an oxygen-depleted state). Install the equipment
on a well-ventilated place, and add a ventilating fan with a capacity of at least 2000 m3/hr airflow.
Do not stay together with a dewar containing liquid nitrogen in a sealed space, such as an elevator or a
car.
The volume of nitrogen gas is 700 times of liquid nitrogen. Sealing liquid nitrogen in an airtight
space produces high-pressure gas of 700 atm and may result in explosion. Use liquid nitrogen in the
condition constantly open to the air.
2. Danger of oxygen deficiency: Ventilate well.
1. Danger of electric shock: Do not touch the live part.
3. Danger of explosion: Do not seal LN

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.
4. Danger of burns or frostbites: Never touch high
or ultra-low temperature parts.
5. Danger of explosion: Do not expose to corrosive
gases.
