Ventilate the room where the instrument is installed. Leakage of significant amounts of hydrogen gas into a poorly ventilated room could result in explosion.
Do not place an ignition source such as fire, electrical discharge or static electricity in the room where the instrument is installed.
These can cause serious accidents, such as fires or explosions.

Do not connect the hydrogen gas tubing to the air inlet. If the hydrogen gas tubing is connected to the air inlet and a large amount of hydrogen gas leaks into the room, there is a danger of ignition.
When hydrogen gas is used as a carrier gas, exhaust gas from the split vent port of the gas chromatograph or the vents of TCD and ECD should be discharged to a ventilation system that does not cause stagnation. It may cause a big accident such as fire or explosion.
