, production of TNT began in September 1915. The method used was invented by Brunner Mond's chief scientist F. A. Freeth, who believed the process to be "manifestly very dangerous". The plant continued to purify TNT at a rate of approximately per day until it was destroyed by the explosion. Another plant, at Gadbrook, was built in 1916 and was producing TNT at a higher rate than the Silvertown factory, away from populated areas, with more stringent safety standards. Both factories were in full production.

The chancel and church hall of the local church, St Barnabas', were destroyed, only to be replaced in 1926. 73 people were killed (69 immediately, and four later from their injuries), and more than 400 injured. Up to 70,000 properties were damaged, 900 nearby ones destroyed or unsalvageably damaged; the cost was put at either £250,000 or £2.5 million. The comparatively low death toll for such a large blast was due to the time of day. The factories were largely empty of workers (there were fewer than forty in the TNT factory itself), but it was too early for the upper floors of houses (which sustained the worst of the flying debris damage) to be heavily populated. Also, it occurred on a Friday, when fewer people were around the factory. However, several professional
