Process Safety · Work within the barriers
Operating integrity
Purpose
Plant is operated inside its safe operating envelope, and work is controlled so that barriers are not bypassed, defeated or overloaded. When a barrier is overridden, the override is authorised and controlled. When prevention fails, emergency response mitigates the consequences.
The question this lens asks
“Does this document create a barrier against a major accident, keep one working, keep work inside one, or build the people who do?”
Belongs here
- Operating philosophy, manuals and operating procedures
- Control of work, permit to work and isolations
- Override of safeguarding systems; operational risk assessment
- Contractor, marine and aviation operations at the worksite
- Emergency response, pollution response and incident reporting
Does not belong here
- Maintenance of the barriers themselves (Asset integrity)
- Occupational safety that does not bear on a major accident (outside this lens)
