In our experience at Mentor FLT Training, these costs are difficult to quantify as they vary so much from case to case. For example, even the cost of a simple dropped pallet can vary greatly depending on the load in question - the stock value written off, replacement costs, the clean-up involved and associated down time will be significantly different depending on the contents (luxury, liquid, hazardous etc).

But what we do know is that these costs can be significantly reduced and the best way to do so is to ensure your operators (and those managing them) have the relevant skills and knowledge to work safely and efficiently.

Our MD has put together some articles on the subject containing various facts and figures which may be of interest, including:
