Posted By Robin B Hi The transport of hazardous substances by road is a very complicated one in which legislation changes are announced every two years. In most cases these changes are minor with the container types staying mainly the same. Biological hazards Class 6.2 are a little difficult to explain even if you are qualified but used srynges for instance depend on the type of material they contained. mostly you'll find that only small quantities are being transported which reduces/removes SOME of the requirements, but you have to be careful of how much [mass] of dangerous substances is being carried in a vehicle. I'd suggest you bite the bullet and hire a DGSA consultant. One thought when I did my course there was a guy from an NHS trust who gaily informed the instructor that dead bodies were classified as dangerous goods. Good luck Robin
