Leakage handling methods

If a hydrogen leak occurs, the solution is to quickly evacuate personnel from the contaminated area, isolate them, and strictly restrict their entry and exit. Cut off the fire source. It is recommended that emergency responders wear self-contained positive pressure respirators. Cut off the leakage source as much as possible. Reasonable ventilation to accelerate diffusion. If possible, use an exhaust fan to send the leaked air to an open area or install appropriate nozzles to burn it off. Leakage containers should be properly handled, repaired, and inspected before use. Fire extinguishing method: Cut off the gas source. If the gas source cannot be immediately cut off, it is not allowed to extinguish the burning gas. Spray water to cool the container, and if possible, move the container from the fire scene to an open area. Extinguishing agent: spray water, foam, carbon dioxide, dry powder.
