In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.
Prevention through design (PtD), also called safety by design usually in Europe, is the concept of applying methods to minimize occupational hazards early in the design process, with an emphasis on optimizing employee health and safety throughout the life cycle of materials and processes. [1]
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 engineering assures that a life-critical system behaves as needed, even when components fail.
The US Navy initiated the Military Manpower versus Hardware (HARDMAN) Methodology in 1977 to address problems with manpower, personnel and training in the service. [7] In 1980, The National Academies of Sciences, Engineering, and Medicine established the Committee on Human Factors, which was later renamed the Committee on Human Systems Integration. [8]
For instance, "user trial engineer" may refer to a human factors engineering professional who specializes in user trials. [13] Although the names change, human factors professionals apply an understanding of human factors to the design of equipment, systems and working methods to improve comfort, health, safety, and productivity.

Effective engineering controls are integral to the original equipment design and work to eliminate or block hazards at the source before they reach workers. They are designed to prevent users from modifying or tampering with the controls and require minimal action from users to function effectively.
Many safety engineers have backgrounds or advanced study in other disciplines, such as occupational health and safety, construction management and civil engineering, engineering, system engineering / industrial engineering, requirements engineering, reliability engineering, maintenance, human factors, operations, education, physical and social ...
