What to do if hydrogen leaks?

bk14.jpg What should be done if there is a hydrogen leak? What about hot hydrogen?
In the case of minor leaks, use fire-suppression steam and have explosion-proof tools ready. The same applies in cases of fires; this approach is only suitable for small leaks and minor fires
After a hydrogen leak, if there is no fire, the main priority is to prevent explosions; it is necessary to continuously monitor the hydrogen concentration in the area, ensuring that it does not exceed the 4% threshold, as this can easily lead to an explosion. When securing the leak points, explosion-proof tools must be used; all personnel on site should wear anti-static protective equipment, a perimeter barrier should be established, and access to any open flames is prohibited. After hot hydrogen leaks, it usually contains oil and gas; in addition to the risk of fire and explosion, it also poses hazards such as burns and respiratory irritation to people. Therefore, when tightening the leak site, personnel must wear protective masks to avoid breathing in and coming into direct contact with the leaking hot hydrogen.

It is not possible to extinguish the fire directly; first, the source of the leak must be shut off, and then the fire should be allowed to burn out. The main goal is to prevent backfire. Using explosion-proof tools is common knowledge that one should be aware of
If it can’t be held in, will the leakage get worse?
““If you can’t extinguish the fire directly,” then doesn’t that mean operations have to be stopped?
That’s not what I mean. First, shut down the source of leakage, and after that, verify that there is no more leakage. Only then can the fire be extinguished. Because if a fire breaks out during the leakage, it can easily lead to an even bigger accident!
If it is possible to approach without fire or with minimal fire, steam shielding should be used first, followed by cutting off the feed. Handling of explosion-proof tools. If the situation on site cannot be controlled, cut off the feed immediately and shut down the operation
Teacher, can it be handled by using a time clock?
In theory, it is possible to use pure hydrogen in low-temperature environments, but supervision is required. Areas with high-temperature oil and gas are not suitable.
