Safety improvement systems engineering approaches

The metliods used in system safety engineering are among tlie most effeetive md advaneed metliods to prevent system failures that result in aeeidents. Altliough system safety engineering is a relatively new field, it lias been used extensively by the military and the aerospace and nuelear industries to improve the safety of higlily eoinplex systems. Tliis approach is based on tlie eoneept tliat ... 

Approaches used to enhance safety in complex systems must take these basic systems engineering principles into account. Otherwise, our safety engineering approaches will be limited in the types of accidents and systems they can handle. At the same time, approaches that include them, such as those described in this book, have the potential to greatly improve our abihty to engineer safer and more complex systems.

This is because many of the factors that have been shown to be the antecedents of major process accidents (e.g., poor procedures, inadequate training) are not usually under the control of the individual worker. The other approaches can also be applied to improving quality and productivity as well as process safety and can be readily integrated with engineering system safety techniques, as will be described in Chapters 4 and 5. 

The International Ergonomics Association promotes a systematic approach to the ergonomic process, to incorporate human factors and human performance engineering and address problems in design of machines, environments, or systems. This can improve efficiency and safety of the human-machine relationship. The basic steps in the ergonomic process include organization of the process, identification and analyzation the problem, development of a solution, implementation of the solution, and evaluation of the result. 

Like most engineering problems, this one does have a solution. And the solution is not that difficult to implement nor costly. What it does entail is considerable forethought, systematic engineering analysis, and a methodical approach to managing risk. It also requires government and industry to collaborate to improve safety as a joint project— not independently. As you will see in reading this book, system safety engineering is not difficult to apply—in fact, it is almost easy.

Standards focus on specifications providing improvements of safety to people and properties. They provide methods for analysis of hazards, risks and quantifying the safety of technical means to ensure the safety of buildings and erection or structures in order to achieve an acceptable level of safety, and provide a systematic approach to the facilities in civil engineering. Technical and safety related subsystems used in facilities of civil engineering are considered as systems of system. Also a holistic view of the entire system is given in Shcherbina, Lubimov, Puzyrevskaya Matveev (2012).
