The Wizard of Oz has some sort of dark stuff in its behind the scenes history. Turns out, one of those things was how much asbestos was used.
From Atlas Obscura:
Despite the fact that asbestos’ health risks were already known at the time, film sets started using one of the purest forms of asbestos on film stages—in part because it was fireproof and looked close enough to snow that it could fool the audience.
The effect was widely used by films of the era, but perhaps best known for Wizard of Oz’s “poppy field” scene, where Dorothy is awoken from a deep slumber after Glinda, the Good Witch of the South, introduces snow to the scene.
That white stuff covering Judy Garland? Pure asbestos, of course—in chrysotile form, making the material a bit more dangerous than, say, in building material. (By the way, not exactly a nice gesture on the part of the Good Witch there, but odds are good she didn’t know about mesothelioma, because not a lot of people did.)
