In the early 1980’s, a client with an OSHA citation and large fine along with countless dollars in equipment and property damage challenged MHS. The process began with developing a more effective way to educate equipment operators in the safe use of material handling equipment. Up to that point, the only thing available was vague regulations, generic canned videos and slide programs. The approach that solved the problems was by properly educating the operators in the conditions that affect the control and handling of the equipment in a variety of their loads and workplace conditions. The most effective change was educating the operators in the real life limitations of the equipment and attachments they use every day.

In 1987 the Industrial Truck Association ( ITA ) started to look into the inadequacies of the existing OSHA regulation for powered industrial trucks.  One of the key ITA objectives was to convince OSHA to change the guidelines for training. In 1988, the ITA petitioned OSHA with specific changes and training requirements compiled by material handling professionals like Guy Snowdy of MHS.

The final hearing was held on May 30, 1996 in Washington D.C. at which Mr. Snowdy testified as an industry expert. The final rule published on December 1, 1998.
