When gasworks helped the War Effort

Lyddite presented a major safety problem because it reacted dangerously with metal bases. This required that the interior of shells had to be varnished, the exterior had to be painted with leadless paint and the fuze-hole had to be made of a leadless alloy. Fuzes containing any lead could not be used with it. When World War I began Britain was replacing lyddite with modern "high explosive" (HE) such as TNT…

….Britain first used pure TNT for land warfare shells from late 1914, but this proved expensive and difficult to manufacture in the necessary large quantities, and was also inefficient as much energy was output as heavy black smoke.

 
And the danger to Munitions workers…

“These injuries could include losing limbs when using dangerous machinery or suffering from burns due to the high risk of fires and explosions caused by the chemicals and acids that were used in the factory. Working with chemicals and acids also increased the risk of workers inhaling toxic fumes. Additionally, working in a munitions factory could cause long term health problems such as lung problems and skin discolouration….”

 
 
“Lyddite had been the preferred explosive before the World War I promotion of TNT, and it had long been known to have toxic effects including jaundice….Factories commonly paid a higher rate to workers in the poisonous explosive area to offset any reservations they might have…..

…..More prevalent, however, and responsible for more deaths of women workers, was poisoning from the TNT with which women workers filled shells. The most visible effect of TNT poisoning was jaundice, and the bright yellow coloration of TNT workers' faces and hands, and their bright ginger hair, became their emblems. Tetryl, lyddite, and CE also had the same effect, so that women who worked with these poisonous explosives became publicly known as "canary girls."​
