Posted By Descarte Since this is involving members of the public? I would be hesitant to give a specific limit without knowing some if not all of the following information: Age, physical condition, past back problems, heart issues, distance carried, handles?, cotents (hazardous?), stability of load, availability of rest, temperature, gradiant, wet/dry?, objects / hazrdas? In essence you need to do a manaual handling assessment of the task, but first I would ask myself, is this task required? Can it be done by another meads, FLT, sack barrow etc....

Posted By warderic If you are selling this product to the public it would be unreasonable to do a risk assessment for everyone. However, if the product is heavy or awkward you need to inform each individual. This can be done by using a label. The label would give the weight etc. It is better not to advise the public on how to carry the product in detail. If you do and an injury happens you will have a claim on your hands.
