No idea. I just work with acetylene and am familiar with old acetylene gas machines which use calcium carbide to make it. I have no idea what those toxins actually do in large amounts because I’m only used to dealing with them as fairly trace contaminants. I just know enough to know that the acetylene itself shouldn’t be much of an issue but those two chemicals could be.
I remember my moms old Garmin GPS always said “turn left down bike path” when we got close to home. I also one heard it tell her to turn left down a river while we were driving over a bridge.
