If it is on steel or stone then it is part of the industrial textures.
Industry uses ANSI, OSHA, D.O.T., standard industrial signs. I have a plastics company catalog that sells all the standard signs. An ANSI, OSHA, D.O.T. sign should be OK to use as long as someones rendering of it is not literally copied.
Skull and cross bones is only used for "Poison".
I suppose a new ANSI standard style sign could be invented, a 2050 era update to the standard signage, now covering more kinds of industrial sewage.
But no joke wad signs please.
You can put skull and cross bones on a wood background.
It was really a pirate sign (used by only a few pirates), but from what I remember one company used it on their product (rat poison I think) and that version was copyrighted (surprise!).
Also can internet search for "ANSI OSHA signs", will get about 3,000,000 hits.
Got out the catalog.
