MLT1985:
Evening all.
I have recently passed my ADR (excluding tanks) and I will mostly be carrying packages.
I know the orange placards must be displayed if carrying over 8 tons of Limited quantities. But am I correct in thinking that they can only be displayed if what you are carrying falls with in scope of ADR.
EG : over 20kg or 20 ltrs or Transport category 1?
Or do you display them when ever you are carrying any ADR regardless of how much?
Cheers
Hi MLT1985,
It seems that you’re confused by the difference between the ‘small load’ exemptions and the LQ exemptions, as well as what is meant by “orange placards.”
Small load exemptions
You seem to have understood the idea of ADR Transport Categories and the exemption limits for each of the Transport Categories ie; 0, 20, 333, 1,000 and unlimited. The part you might have missed is that this idea applies to normal everyday packages such as drums, boxes, IBCs, crates, jerricans, gas cylinders etc. In this case the limitation is on how much ‘stuff’ you can load without attracting the full weight of all applicable ADR provisions for those dangerous goods. In this case, orange coloured plates (not placards) must be displayed when your load exceeds the relevant ADR Transport Category.
LQ exemptions
The idea of LQs is completely different to the above.
The limitations regarding LQs apply to the size/weight of the packages.
The best way to think of LQs is that they are the kind of dangerous goods that you can buy in a retail shop AND packaged in that way, ie; for retail sale in a shop. The maximum size for LQ receptacles is 5Kg/L, but for some substances the limit is lower.
There are only two ways to package LQs… 1.) A box of no greater than 30kg containing one or more receptacles, or a stretch-wrapped tray of no more than 20kg containing receptcles.
If the LQ rules on package weights are respected (this depends on the customer’s order) , then there is NO limit on what can be carried in terms of the 0, 20, 333, 1000 or unlimited because that’s the rule for a different exemption.
