ABSTRACT
This chapter discusses the concerned with the methods used to identify hazards and the causes and consequences of accidents. The causes of accidents have to be identified in order to help prevent accidents from occurring. Any situation or characteristic of a system, plant, or process that has the potential to cause damage to life, property, or the environment is considered a hazard. The process of cause-consequence evaluation usually proceeds as follows: As its name implies cause-consequence analysis allows one to see how the possible causes of an accident and the possible consequences that result from that event interact with each other. Many accidents occurred because of a lack of knowledge of the system, process, or substance being dealt with. Risk evaluation of accidents serves a dual purpose. It estimates the probability that an accident will occur and also assesses the severity of the consequences of an accident. Consequences may include damage to the surrounding environment, financial loss, injury to life.
