System Safety Engineering

System Safety Engineering entails the application of engineering and management principles, criteria, and techniques to optimize safety within the constraints of operational effectiveness, time, and cost throughout all phases of the system or facility life cycle.

APT engineers have established a dependable process to conduct System Safety Engineering. This process includes the following seven steps:

  • Identify hazards
  • Define the risks using hazard analysis techniques as early as possible in the system life cycle
  • Develop options to eliminate or control hazards
  • Provide for timely resolution of hazards
  • Define residual risks
  • Track hazards to closure
  • Obtain proper approval

Implementation of the seven-step process involves support activities which include:

  • Program tailoring
  • Defining safety criteria
  • Analyzing system hardware / software designs using fault tree analysis and other techniques
  • Issue resolution
  • Hazard tracking systems
  • Risk assessment
  • Environmental protection
