Any ideas what these signs on this building mean? (lemmy.ml)

Aside of these signs and the address numbers, the building is completely unmarked.

You have good instincts - that's also what NFPA recommends. This isn't a typical presentation as usually it's one diamond with the worst score of all present chemicals in each category.

You CAN list them individually but it's a pain in the ass for both the building owner and first responders. The whole point is to quickly convey the level of hazards in the building for emergencies. They need to know if they need more information before entering. 2+ diamonds doesn't provide any additional useful data and makes it harder to interpret in a rush.
