Over 900,000 women worked in munitions production during the war, facing TNT poisoning which turned their skin yellow and earned them the nickname ‘canaries’. More than 300 women died from the effects of TNT or as a result of explosions and accidents. This photograph, from September 1918, shows a workshop in the Belgian Munition Works, Richmond-on-Thames, which employed Belgian refugees to manufacture hand grenades and artillery shells.
