I got the 1000 litres mark from one of our guys using a 1000 litre tank to take fuel round and dispense it to the gangs for light plant.
Hi mikeb, That figure of 1,000ltrs is correct for Diesel fuel.
mikeyb:
As I know that ADR is not applicable to it.
Sorry Mikey, that’s not quite correct, because the 2kg dry-powder fire-extinguisher I mentioned above IS in ADR, and it’s the only subsection of ADR that DOES apply to that job. 
mikeyb:
I may be mistaken but isnt there a max allowance for vehicles carrying mixed loads? eg a whitelining vehicle may carry a few bottles of gas, a fair amount of diesel etc etc
This is going back a few year mind when I was involved in ADR and i was only “a bit” involved.
If I remember there is a calculation and a max figure that you cannot exceed.
TBF mikey, that’s not a bad recollection you’ve had, but the Regs changed big-time in 2004. A couple of minor things happened in 2005 and 2007, but there’s just been another change that came in on 01/07/09.
Ther’s also the question of wording, so I’ll have a go at clarifying this for you…
There are limits applicable for carrying dangerous goods of different Transport Categories on board the same vehicle, BUT they work in the same way to give you a ‘freebie,’ rather than an absolute maximum.
There are only a few dangerous goods that have an absolute maximum amount allowed per vehicle load, but that doesn’t include petrol, diesel or propane. Dangerous goods of that type have a maximum allowed per vehicle, regardless of whether the driver holds an ADR licence, because they are spectacularly dangerous and very probably have a ‘freebie’ limit of zero.
mikeyb:
You probably have covered it in your post but I am that tired I cant read today 
I haven’t covered the subject of ‘freebies’ for carrying mixed Transport Categories, because there is now a calculation to be made, so I would have to decide on a case-by-case basis once somebody tells me what exactly it is that they wish to carry, how it’s packaged and the amounts. In any case, it’s no longer a part of an employed driver’s duties to know how to calculate this.
