The links aren't a complete list of codes, as there are a lot of custom ones for specific chemicals. But for a pipeline i'd think it was more likely to be a common chemical.
It could also be the "facility" is rated that way. I'm not sure how the signs on a side of a building (vs on the side of a gas tank) works as it might just be a warning to firefighters for the building as a whole.
True. I was just thinking it could also mean that they store that chemical. I jumped to the conclusion of thinking it was a pipe because of the bricks protruding from the wall, but it looks to just be an architectural design choice.
