Q.
With the 54 Edition, the requirement is mentioned in 7.1.4.2 and with the 55 Edition, this has been relocated to 7.1.7.2 where it says when multiple overpacks are made, to facilitate identification, loading and notification, the operator “requires” each overpack to show an identification mark (in any alpha-numerical format) and the total quantity of dangerous goods, as indicated on the DGD. If there are more than one UN number, the total quantity of dangerous goods must be shown by UN number. The word “requires” is used. Does this imply that this is a mandatory requirement (a “must”) or is it a wish (a “should”)?  (30 Nov 13)
