As others have said, these are NFPA signs.
What I want to know is why there are two different ones. What the hell does that mean?
Two different chemicals to be aware of
But it's just slapped on the side of the building with no indication of which chemicals the labels are for, I don't think that's how it's supposed to be done. It'd be like mixing two chemicals into a bottle and then putting two labels on it.
I think there should just be one label that combines the warning levels of both i.e. 3-2-2-W
i would hope that there would be labels inside the building that would indicate which is which, but who fucking knows with the us lol
They generally have them on the containment units, and if they're used elsewhere, on the pipes/machines carrying/using the chemicals.
Now, if they've been properly replaced since installation is a completely different question. I've seen far too many faded/shredded diamonds on the sides of things.
