There seems to be a growing problem with freight containers imported into the UK; the Health and Safety Executive is getting an increasing number of enquiries asking for advice. Over the past two years, 7,760 containers stopped in roadside checks were found to be overweight, and one company had to call the HSE when a container overturned while being unloaded. Shippers are obliged by law to declare the correct weight to shipping lines, and there is no incentive to under-declare as shipping freight rates are based on the size of the container, not the weight. There have been accidents due to over-loaded containers bursting open, and there is to be an international effort to revise the guidelines on loading.
