Retrospective hazard review

Retrospective hazard review is a team based hazard identification and risk assessment technique that enables continuous improvement in process safety for existing major hazard facilities. 

The review has a structured system-by-system (PHR) or line-by-line (HAZOP) approach focusing on hazardous events with the potential to cause significant harm to people, the environment or the business / reputation.

Retrospective Hazard Reviews have been used to meet regulatory or company requirements for the periodic revalidation of Process Hazard Analysis (PHA). PHR takes a higher level and more time efficient approach focussing on loss of containment and release of energy events. HAZOP studies may be required in order to revalidate the process design and operation if required by companies wanting re-assurance that all aspects have been considered.

Reviews produce risk based recommendations building on the operational experience of the team and targeted towards areas of real concern. These include verification of critical safeguards such as pressure relief and safety instrumented systems, plus design checks or essential improvements to hardware or operating / maintenance / inspection procedures.

To assist with effective follow-up to these reviews, ABB provides an action close-out service. This includes any further assessment needed to convert recommendations into specific actions, plus an option for full management of the action plan through to effective close-out and realisation of the benefits.
