The factory in August of 1917.
On the 1st of July, 1918, the deadliest explosion in British history occurred near Chilwell in Nottinghamshire, England.
The disaster happened at National Filling Factory No. 6, a First World War munitions factory that had been in operation since 1915. The factory was known for its “Canary girls“: women shell makers.
On the day of the disaster eight tons of TNT blew up, killing 134 people and injuring 250 others, however newspapers at the time reported a much lower death toll.
The site of the factory is now home to Chetwynd Barracks.
