Hydrogen Release from the Hose of Trailer, Followed by an Explosion and a Fire
A hose of a hydrogen tanker parked in at a specialised company ruptured. The released hydrogen ignited and exploded, followed by a fire probably fed by the continuously leaking hydrogen. The local fire rescue team rushed to the scene after receiving the alarm call. The fire was quickly brought under control and extinguished. Firefighters continued to cool the tank to avoid further problems. There were no casualties at the scene. There were two hydrogen trailers parked at the accident site. The other truck was not affected.

The description of the event does not provide enough details to draw a specific lesson learned. The editor of the news at the website used as a source for this event, wrote the following:"Relevant specialist enterprises should understand the risks and hazards associated with hydrogen, establish safety rules for the use of hydrogen. They should also be well prepared with counter measures to deal with accidents, prevent problems before they occur, and prevent incidents from occurring. It is also necessary to have clear understanding about how to handle hydrogen safely to prevent similar accidents from happening again." https://new.qq.com/omn/20210807/20210807A02SN600.html
