I think you got the right idea but that description is missing the big points.

They were painting watches and their employers told them to use their lips to make fine points on the brushes, meaning they ingested a ton of the paint. The employers told them it was harmless despite evidence to the contrary. They chose not to use other options because wiping the brush on their lips increased productivity and they were paid per watch.

I don't think you meant to imply that they were doing it for trivial reasons, but I do think mentioning that they were doing it for a job and that their employers were intentionally deceiving them is important context!

A decent amount of safety law was written in the blood or sweat of women. The origins of fire code come from the Triangle Shirtwaist Factory Fire which manufactured garments in New York which was staffed almost entirely by women.

Not to say a lot of safety law wasn't developed because of the deaths of men but a bunch of women dying all at once due to negligence does seem to be a decently galvanizing force for society which makes it easier to get a ball rolling and women, particularly widows and family members of victims , have always been important advocates and organizers in the fight for safety legislation.
