Far too often, we are hearing about workers in our industry being hurt or killed by falling slabs, and it is time for this to stop. There are enough sources of information on proper material handling out there - including a myriad of materials from the Marble Institute of America - that ALL of the people working in our industry can be educated.
My take on the situation is this: most shop and warehouse owners and managers seem to have invested in the right handling equipment and storage racks, and they generally understand proper material handling. However, their employees - the ones who are actually maneuvering the material - are often sorely lacking in this knowledge, and this is the area that needs to be addressed.
