Before supplying hydrogen gas, confirm that all the connections are completed or the outlets are blocked off. Failure to do so can cause serious accidents, such as fires or explosions.
If it is believed that hydrogen gas has accumulated, carefully eliminate the accumulated gas. If the gas chromatograph is turned on inadvertently without removing the accumulated hydrogen gas, there is a danger of explosion. For details about the procedure for removing accumulated hydrogen gas, see Recommended Emergency Measures.
Each time the instrument is used, confirm that there are no leaks in the hydrogen gas line. Failure to do so can cause serious accidents, such as fires or explosions.
The stop valve should be inspected at least once every two years. If a leak is discovered, contact your Shimadzu representative for replacement. Apply gas leak detection liquid (not SNOOP or any other detergent! 50% methanol/water is a suitable frothing liquid) to all joints and check for leaks.
In the event of a power outage, stop the supply of hydrogen gas. Failure to do so can cause serious accidents, such as fires or explosions. For details about the procedure for stopping the supply of hydrogen gas, see Recommended Emergency Measures.
