Posted By WayneF Learned members Can anyone point me in the direction of the legislation regarding the need to display warning signs for various hazardous substances carried on vehicles. I believe gas cylinders are covered but not sure about cylinder size, and I am unsure if signage is needed for casual carraige or just constant (though it shouldn't make any difference). Thanks Wayne

Posted By Dave Wilson Marking and placarding of vehicles which transport Dangerous / Hazardous good is covered in CDG Regs 07 and ADR. You only have to do this when the vehicles are 'ACTUALLY' in scope when carrying, it is an offence not to display and it is also an offence to display when not carrying DG's. I know that some people put the classification signs i.e. compressed gas, on the back of vehicles etc, there is no legal requirement to do so, this 'Class Sign' does not mean diddly squat to the Emergency Services unless it is accompanied with the UN Number and the EAC code. What type of Compressed gas? How would the Fire Service know what type of extinguishing media is required and how dangerous is the stuff being carried.

Posted By Jay Joshi You could refer to BCGA's Guidance for drivers at work titles "Carriage of gas cylinders by road in cars, vans and other vehicles" at:- http://www.bcga.co.uk/publications/L1.pdf

Posted By WayneF Steve/David Thanks for the response guys, it's all been very useful. On the whole we meet the exemptions for display but find it strange there isn't an intermediate colour for small quantities, I mean how many cylinders need to explode to be considered dangerous? David I would like to take you up on your offer of the handbook but not sure how to contact you direct? (am not a fully paid up member (BIFM man))
