Handling High-pressure Gas
PDA-7000 requires the use of high-pressure argon gas.
Note that the following points regarding the handling of high-pressure gases in Japan:
1) By law, permission is required to use cylinders containing more than 300m
3
.
2) When using gas of a pressure that exceeds 980.665kPa (10kgf / cm
2
) inside the
equipment at room temperature, the equipment is regarded as high-pressure gas
equipment and, by law, notification of use must be submitted.
Refer to your government laws and regulations related to high pressure gas control,
liquefied petroleum gas control, general high pressure gas control, and fire defense.
Also, follow the precautions and instructions below for the safe use of high-pressure gas.
● Install the gas cylinder in a well-ventilated outdoor location that is
not exposed to direct sunlight and convey the gas indoors via a pipe.
Regarding liquefied gases in particular, this setup is required by law
in Japan.
● Ensure that the temperature of the gas cylinder never exceeds 40°C.
Also, ensure that there are no open flames within 2m of the gas
cylinder.
● Ensure that the location where high-pressure gas is used is well
ventilated and, as part of initial inspection, check for gas leaks with
soapy water.
● Prevent the cylinder from falling or toppling over by securing it with
rope or chain. Be sure not to let liquefied-gas cylinders topple over
into a horizontal position.
● After using the gas, close the cylinder's main valve immediately.
● Inspect the functional capability of the pressure gauge at least once
every three months.
