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. No idea where this figure showing EU-specific hazards for containers and US-specific hazards for transport together would’ve come from.
