Explosion at a gas manufacturer

The explosion occurred at the premises of a manufacturer of special gases. A hydrogen trailer in the trailer parking lot had leaked hydrogen, which then ignited. The explosion was clearly audible in the neighbourhood. A fire engulfing other combustible materials, such as the tyres of the trailer, followed the explosion. The smoke cloud was visible from far.
The plant fire brigade was immediately on site and brought the risk under control, by fighting the fire and keeping cold the surroundings. No one was injured. From the pictures released by the sources, it can be deduced that a full bundle of vertically structured hydrogen bottles burned down, affecting also two adjacent trailers carrying horizontal tubes. Some of the bottles of the burned down bundle are seen metres away from the original location, one being almost completely charcoaled .

The explosion was clearly audible in the immediate vicinity as a loud bang, which also damaged some nearby window panes. The subsequent fire on the trailer and its tyres produced a large cloud of smoke.
Hydrogen off takers, especially the refuelling stations (including a hydrogen train service), experienced shortage of hydrogen delivery for at least 14 days.

the plant fire brigade of a neighbouring company and the volunteer fire brigade of the city were called in.
The company temporarily withdrew the hydrogen trailers of the same series from service as a precautionary measure.
