Explosion in Microbiological Anaerobic Chamber - (717)
The Microbiological Anaerobic Chamber of approximately 2 m3 capacity was containing an explosive mixture of hydrogen and air. A fire followed the explosion, but was rapidly extinguished by staff using fire extinguishers, prior to the arrival of fire service personnel. The pressure wave from the explosion blew windows out of the laboratory, with glass hitting a passer-by on a path outside, and glass shards landing up to 30 m away.
