Chemical names on prohibition signs

[Katavia]

Only ones I can think of is on A-10/A-8 in France and Italy but I do not live anywhere near there so no pictures

Any others?

Unfortunately those big honking PA Turnpike signs use all generic names so I guess they can't count.

There's "Organic Peroxide" I think

that's a class of chemicals, just like all of the others on that array of signs.

It doesn't take a pharmacopeia to tell you which chemicals are bad. If it can kill you, it probably should be banned in certain spots.

O₂ and N₂ in excess of what they should be actually can be fatal.

Is that sign missing a "call to action"  at the bottom? "PROHIBITED VEHICLES _______?"  The other such signs I recall seeing have an instruction at the bottom such as "USE THIS EXIT" . (Like this one.)

Mass Pike eastbound at I-95/128 (Interchange 14) has a sign reading "Propane LNG Cargoes Exit (with arrow)."
