my opinion....?
DEADSET ILLEGAL under the IATA dangerous goods regulations. regardless of how they are secured, or even what type of container they are carried in.
Without a proper Dnagerous goods manifest and checklist with accompanying NOTOC and DG carrying approval, you are asking to be ramp checked.
A quick check of CASA CAR's/CAO's will refer you to the IATA dgr's and basically state that you MUST comply with the IATA DGR's to comply with the CASA CAR's/CAO's.
FTDK.... even that mogas driven gennie is illegal, IMHO.
