Systems Safety

System Safety is the discipline that uses systematic engineering and management techniques to aid in making systems safe throughout their life cycles.

The Need:

  • The safety of an operation is determined long before the people; procedures and hardware come together at the work site.
  • Improvements in Safety can be made with a minimal effort and cost if they are made far enough upstream.
  • Safety is achieved by doing things right the first time, every time.
  • To identify analyse and control hazards.

Fundamental Safety Concepts:

Does your company believe that:

  • Safety is a line responsibility?
  • Safety is productive?
  • Safety requires upstream effort?
  • Safety depends on the safety precedence sequence?
  • Systematic tools and techniques help?

If the answer to any of these questions is yes, then your organisation can benefit from the use of the systems safety tools.

Safety Precedent Sequence:

Safety depends upon the safety precedent sequence. It is a prioritised list of controls that should be considered and applied, in sequence, to eliminate or control identified hazards.

  • Design for minimum hazard.
  • Provide safety devices.
  • Provide warning devices.
  • Control with procedures and training.
  • Accept remaining residual hazards.

Project Phases:

Projects generally follow the following phases:

  • Concept.
  • Design.
  • Construction & Commissioning.
  • Operations.
  • Disposal.

The application of systems safety at the concept and design phase of a project leads to cost effectiveness. The later in a project change is made, the more difficult and costly the change is to implement.

Signal Safety & Training Ltd. Provides:

Signal Safety & Training Ltd., provides leadership services for the following systems safety processes:

  • HAZOP - Hazard and Operability studies.
  • SIL Assessment / Validation
  • SAFE Charts
  • Energy Trace and Barrier Analysis.
  • Failure Mode and Effects Analysis.
  • Fault Tree Analysis.
  • Event and Causal Factors Charts.
  • Management Oversight and Risk Tree.

The enlightened leadership of safety, engineering and management results in proactive safety where loss does not have to occur before action is taken.
