Scottr Had to cover movement of 100 litres of fuel ourselves recently - we found the following information from the HSE website helped us out ... The Carriage of Dangerous Goods and use of Transportable Pressure Equipment Regulations 2004 (CDG), as amended by The Carriage of Dangerous Goods and Use of Transportable Pressure Equipment (Amendment) Regulations 2005 require that petrol should be carried in UN approved containers (called Packages), which are properly stowed on the vehicle. The packages should be marked with the 'flammable' diamond and with the UN number for petrol (UN 1203). Up to 333 litres may be carried as a 'small load' which means that only general training needs to be given to the driver and that the vehicle only needs to carry 1 2kg fire extinguisher. These regulations do not affect purely private carriage. More information on carriage may be found at www.hse.gov.uk/cdg[1] Regards CDB193

Bob Where did you get the bulkhead guidance from or is it just good practice?

Bob, Understand what you're saying but there are various bulkhead types that come as factory fitted; not all will provide an airtight seal between cab and load area, and are merley there to provide the cab occupants with a degree of protection from the load in the event of hard braking of an RTA.
