Safety engineering is an engineering discipline which assures that engineered systems provide acceptable levels of safety. It is strongly related to industrial engineering / systems engineering , and the subset system safety engineering.
Safety engineers work in a team that includes other engineering disciplines, project management, estimators, environmentalist, asset owners, regulators, doctors, auditors and lawyers. Safety works well in a true risk matrix system, in which safety is a managed by the ISO3100 risk management system and integrated into the safety, quality and ...
Software safety (sometimes called software system safety) is an engineering discipline that aims to ensure that software, which is used in safety-related systems (i.e. safety-related software), does not contribute to any hazards such a system might pose. There are numerous standards that govern the way how safety-related software should be ...
Safety engineering is an applied science strongly related to Systems engineering. Safety engineering assures that a life-critical system behaves as needed, even when pieces fail. The main article for this category is Safety engineering .
A root cause analysis identifies the set of multiple causes that together might create a potential accident. Root cause techniques have been successfully borrowed from other disciplines and adapted to meet the needs of the system safety concept, most notably the tree structure from fault tree analysis, which was originally an engineering technique.

In fact, safety issues have been discovered one by one, over more than a century in the case mentioned, in the work of many thousands of practitioners, and cannot be deduced by a single individual over a few decades. A knowledge of the literature, the standards and custom in a field is a critical part of safety engineering.
Hierarchy of hazard control is a system used in industry to prioritize possible interventions to minimize or eliminate exposure to hazards. [a] It is a widely accepted system promoted by numerous safety organizations.
Some safety organizations provide guidance on safety-related systems, for example the Health and Safety Executive in the United Kingdom. [6] Risks of this sort are usually managed with the methods and tools of safety engineering. A safety-critical system is designed to lose less than one life per billion (10 9) hours of operation.
