Safety engineering content covers topics like hazard identification techniques (HAZOP, FMEA), risk assessment methods (Fault Tree Analysis, Bow-Tie), safety management systems (OSHMS), accident investigation, human error analysis, and safety by design principles. It encompasses methodologies and tools to prevent accidents and protect people, property, and the environment, often integrating safety into the entire lifecycle of a system, from design to operation and maintenance.
The need to avoid or mitigate specific hazards is captured in safety requirements. In engineering, a requirement is an instruction to the designers or operators of a system specifying some behaviour or quality the system needs to have, or some condition that it must bring about or maintain.
