If there are 2 or more different hazards the placard must be shown on the same horizontal plane. When multi-loads are carried each compartment must display the UN number on each side.
No UN number is shown to the rear.
The emergency action code should be shown to the rear. The one exception to this rule is for multi loads of petroleum fuels. These can be marked as a single load as long as the details shown are that for the lowest flashpoint product.

If a tank is carrying materials where the temperature is above 100’c this sign must be displayed next to all normal markings.
