Those are DOT Hazmat placards for transport, often having a U.N. Number for specific substances (e.g. gasoline is 1203)
NFPA 704 is the multicolor four square thing with numbers in them you might see outside of a business.
Blue = Health,
Red = Flammability,
Yellow = Reactivity,
White = Special (e.g a ~~W~~ indicates reactivity with water)

The upper row is from the EU's Directive 67/548/EEC which has since been replaced with the international GHS (oddly enough a UN standard instead of ISO). The lower ones are in fact the DOT symbols from the US rather than the very similar GHS transport symbols (including the UN numbers). No idea where this figure showing EU-specific hazards for containers and US-specific hazards for transport together would've come from.
