The incident occurred at a fuel cells manufacturing plant. The tanker was preparing to transfer liquid hydrogen to the company hydrogen bulk storage tank. During backing, it impacted an industrial building, causing a hole in the tank, with consequent leak and ignition. When the City fire brigade arrived on scene, the hydrogen gas was still escaping from the leak feeding the fire. They let the fire burn out and kept dousing the tanker till Saturday to reduce the temperature and to minimise possible the risk of explosion. A technician of the company delivering the hydrogen arrived on the site and isolated the leak by shutting off a valve.The truck driver suffered minor burns to his face but there were no other injuries or damage to the plant.
