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 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.
