Thank you for your very kind feedback Varrie. We always enjoy coming to see you. Your point on marking and labeling is a valid one. Part of our challenge with one day courses is making sure we get the basics of transporting dangerous goods across, before we can go through marking, labeling and documentation in depth. It is something we're looking at though and will take your comments on board. For your own future reference, please do hang onto the workbook as there are examples in there.
