Thanks for the links! I’ve been searching for any sort of clue, but I haven’t had any luck either. I wonder if it’s an older custom sign and the codes have changed through the years? Maybe you’re right about it being odd and has been updated officially, but they just never updated the sign.
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.
