Abstract: This paper describes the fishbone diagram, Heinrich’s Law, and iceberg theory. By using fishbone diagram tool, it analyzes the causes of one index finger cut accident. Combining Heinrich’s Law, iceberg theory with the accident, the paper discusses the safety management methods in enterprises. The results indicate that the index finger cut accident was caused by the unsafe state of people and things, and many other factors that were not eliminated in time, resulting in unsafe behaviors of people which led to the index finger cut. Therefore, corporate safety management should focus on staff management and building good safety culture. The overall level of corporate safety management can be improved fundamentally through improving employees’ professional technology and knowledge of safety, enhancing risk identification abilities, realizing intrinsic safety, removing system defects and making efforts to control risks from the sources and reduce unsafe factors. These can greatly reduce the number of accidents and the probability of accidents, thus the overall safety management level of the enterprises can be improved fundamentally.
