Human Factors Analysis of Materials Handling Equipment

摘要

Human factor deficiencies in the design and operation of powered industrial trucks, powered cranes and hoists, and powered conveyor systems were evaluated. Information concerning the major categories and causes of accidents involving materials handling systems was furnished by Wisconsin workers' compensation case histories, accident investigations, and employee reports of injury. The Wisconsin data was supplemented with new information gathered from on site observations of the actual equipment in use. Specific design deficiencies were not as critical in causing accidents as were deficiencies in proper applications of the equipment, inadequacies in the use of accessory tools and equipment, and general management and system inadequacies in the development and exchange of relevant information concerning hazards and proper equipment use. The authors conclude that the hazards of industrial materials handling systems are not managed properly, resulting in uncontrolled hazardous conditions and behaviors that produce injuries and illnesses. The authors recommend that improvements be made in standards for equipment and its utilization, and that further research be conducted.
