What do the numbers in red diamonds on trucks’ liquid tanks mean?

Arpeggi asked:
I know that the numbers (usually 3-4 digits) enclosed in a red diamond on the back and sides of truck tanks indicate exactly what liquid is inside. Does anybody know where I can find a listing of these numbers and what they stand for?

The numbers identify what the truck is carrying. The numerical system is used on rail way tank cars.
