That one I think was basically a late response to all the ways folks used to kinda find themselves on fire.

Advent and proliferation of gas stoves, cigarettes, and cool new “space-age” (hyper-flammable) building and textile materials. Probably lotsa extra reasons and compounding factors, too, frankly there was (and is) a lot to figure out lol.

You might even have found yourself on fire back then, too!
