Which industry is the safest and most trusted in the world? The answer is no profession or industry system in the world that can guarantee zero accident rates, such as healthcare, manufacturing or engineering. unimaginable disasters always happen, it causes new generation of engineers have to study the reasons for their emergence and increase related of ethic of engineering to avoid any accident as much as possible. People in engineering believe trial and error are a way to move engineers abilities forward, however, the cost is sometimes unimaginable. When a disaster is caused by an engineering failure, we call it an engineering disaster. For example, the sinking of the Titanic was one of the most famous engineering accidents. The cause of the accident was the failure of the quality of the rivets and the sealed compartment was not individually sealed (Pruitt, 2018). After the accident, 1,500 people dead and the total number of people on this ship is only 2,208 (Praveen, 2020). Therefore, t
he Titanic is one of the most important engineering disasters worthy of the attention of future generations of engineers. On the one hand, practices and disasters push for engineering to deeply study the damage mechanism of materials in order to control severe engineering disasters. On the other hand, the moral standards of engineers have been repeatedly stressed due to various serious accidents. The purpose of this paper is to take another major engineering accident as a case study, namely Chernobyl, to explore the possibility of this engineering disaster occurring after the engineers clearly applied the ethical standards. The paper will introduce the disaster background of the nuclear power accident, its causes, the moral issues of the engineers involved, and a summary of the former Soviet government’s response to the disaster. Finally, the paper will determine the engineering ethics that engineers should follow and the likelihood of avoiding case accidents after applying those ethics.
