Safety

Safety is the state of being "safe", the condition of being protected from harm or other danger. Safety can also refer to the direction of recognized hazards in appearance toan acceptable level of risk.

System safety in addition to reliability engineering

System safety & reliability engineering is an engineering discipline. Continuous make different in technology, environmental regulation and public safety concerns make the analysis of complex safety-critical systems more and more demanding.

A common fallacy, for example among electrical engineers regarding structure energy systems, is that safety issues can be readily deduced. In fact, safety issues score been discovered one by one, over more than a century in the case mentioned, in the work of numerous thousands of practitioners, and cannot be deduced by a single individual over a few decades. A knowledge of the literature, the indications and custom in a field is a critical element of safety engineering. A combination of view and track record of practices is involved, and track record indicates some of the areas of abstraction that are relevant. In the US, persons with a state license in fine such as lawyers and surveyors technology in Electrical Engineering are expected to be competent in this regard, the foregoing notwithstanding, but most electrical engineers have no need of the license for their work.

Safety is often seen as one of a business of related disciplines: quality, reliability, availability, maintainability and safety. Availability is sometimes not mentioned, on the principle that this is the a simple function of reliability and maintainability. These issues tend to establishment the utility of any work, and deficits in any of these areas are considered to a object that is said in a cost, beyond the exist of addressing the area in the number one place; good management is then expected to minimize written cost.
