What were the canary girls like?

Canary girls were young female workers in the early 20th century, particularly during World War I, who were employed in munitions factories to produce explosives. They earned this nickname due to the yellowish tint their skin and hair acquired from handling toxic materials, especially TNT, which caused a condition known as "canary poisoning." Despite their crucial role in the war effort, these women often faced hazardous working conditions and health risks. Their contributions have since been recognized as significant in challenging traditional gender roles in the workforce.
