A.
There is basically no need to segregate Class 3 and Class 9. Table 9.3.A shows Class 9 however it only refers to the segregation of lithium batteries with other flammable substances as spelled out in DGR 9.3.2.1.3.
The first lot of 14 pieces of overpacks with UN 3166 Vehicles has no problem however, Overpacks #5 and #8 must be corrected to show as indicated below.
UN 3528 Engine, fuel cell, flammable liquid powered Class 3 PI 378
1 Engine X 45 kgs
UN 3166 Vehicle, flammable liquid powered Class 9 PI 950
1 Vehicle X 50 kgs
Overpack used #5
Total Quantity of Overpack 45 kgs, 50 kgs.
(Not to be added since the UN number is different.)
Thence, Overpack #8 must be shown as follows:
UN 3528 Engine, fuel cell, flammable liquid powered Class 3 PI 378
2 Engines X 80 kgs
Overpack used #8
Total Quantity per Overpack 160 kgs
Please correct as aforementioned.
