Standup forklift trucks are extensively used primarily for material handling in high density warehouses. These forklifts over the years have been involved in severe accidents causing injuries and taking lives of the operator and that of people on the floor. The major accidents involving these trucks are tip-over, off the dock accidents, compartment intrusions and under the rack injuries. The objective of the work is to analyze the accident data and to provide a conceptual design to ensure safety of the operator riding the standup forklift trucks. The operator is assumed to be safe when retained within the compartment similar to that of the safe space environment of a sit down forklift truck or tractors. Thus a door on the standup forklift would provide a safer compartment. This design would help in preventing severe injuries to the operator in case of any accidents. The important criterion of this design is to provide a door with latch and slide mechanism to ensure easy egress and ingress of the operator. The compartment is designed ergonomically for 95th percentile industrial male population. The accident data is studied by performing statistical and failure analysis. Weibull plots are fitted for life time distribution data and are found to be of increasing rate. This suggests that present safety precautions are increasingly ineffective.

Profit, ergonomics, safety, employee morale, quality, efficiency, and productivity are critical components that greatly impact company success within manufacturing organizations. Therefore, it is essential that a valid and reliable systematic approach that encompasses all of these factors be developed for use by top management in today's rapidly changing manufacturing environment. Organizational-level decisions made based upon a single goal or narrow perspective that only considers one of the aforementioned components, such as profit, while ignoring others, such as employee morale, have proven harmful to the long term viability and success of manufacturing companies. Often organizational leaders are not adequately equipped to consider multiple factors that are pertinent to company success due to the complexity associated with considering a large number of organizational variables and the lack of quantitative tools and techniques to assist in this process. Thus, valid, reliable and readily available tools, methods, and techniques for integrating into decision making multiple components of profit, ergonomics, safety, employee morale, quality, efficiency, and productivity are highly needed in today's complex manufacturing business environment. This research responds to the need to develop quantitative models by creating a company success index. This index was developed using an approach to analyze and evaluate multiple factors at the strategic, tactical, and operational levels of an organization that are essential to achieve company success in manufacturing enterprises. The resulting company success index model was validated using information on market share (Specificity = 0%, Sensitivity & Accuracy = 87.5%). Future research related to this topic area should include additional studies to expand upon model validation and verification techniques.

The aim of this thesisis to defineand clarify the concepts of safety and hygiene at work in building industry. The theoretical part explains the issue of hygiene in the building industry. Second part of theoretical part is devoted to safety of work. The thesis is dividend this way to secure that practical part, which deals with securing of safety and hygiene at work in building companies, is fluently continued by theoretical part.
