ABSTRACT
An accident is an unplanned and unexpected event that results in mishap. Accidents may result in property damage, interruption of work, loss of life, or injury. Accidents are the result of the failure of people, equipment, materials, or the environment to react as expected. The Directorate General of Mines Safety has analyzed the types of accidents and classified them in nine categories according to their causes. The safety performance of a mine is often judged according to the number of accidents happening at that mine. The number of accidents can be expressed using various types of rates, that is the frequency rate and the severity rate. When an accident occurs, it may have different consequences, such as property damage, interruption of work, loss of life, or injury, and all these consequences present great costs to management, to the injured, and to society. The direct costs of an accident include medical costs and compensation payments made to the injured employee.
