Safety Requirements Specification Authoring
The document that decides whether the system you get is the system you needed
The safety requirements specification is the handover point between those who understand the hazard and those who will build the system. Most are incomplete in the same predictable places. This workshop has delegates author and then peer review a full specification.
This course sits alongside our Safety Requirement Specification consulting work, so what is taught is what we do.
Who should attend
Course content
Every module is taught with worked examples and exercises drawn from real plant, and adapted to your own process where the course runs in house.
What the specification must contain
- The full clause requirement set, worked through in order
- Functional requirements against integrity requirements
- Process safety time and its effect on response requirements
The parts that get left out
- Trip setpoints with their basis rather than just the value
- Reset philosophy, manual shutdown and start up override provisions
- Behaviour on loss of power, air and communications
- Diagnostic and alarm requirements
- Proof test requirements written to achieve the coverage assumed in verification
Interfaces
- Boundaries between basic process control and safety systems
- Operator interface requirements and bypass access control
- Requirements passed on to maintenance and to operations
Authoring workshop
- Delegates write a full specification for a provided hazard scenario
- Structured peer review against a completeness checklist
- Revision in response to review findings
What you receive
- A safety requirements specification template
- A completeness review checklist
- The specification each delegate authored, with review comments
- Assessment result and attendance record
What changes afterwards
- Integrators build what was intended rather than what they inferred
- Proof test procedures are specified to achieve the coverage the SIL claim assumed
- Fewer late changes discovered at factory acceptance testing
- Assessment findings against specification completeness drop sharply
