Hazard and Operability Study HazOp Scotland
Hazard Studies are an established series of risk assessments carried out throughout the lifetime of a project or process. They call on other risk assessments required by legislation and standards. The extent of the risk assessment required will vary depending on the customer and the scope and scale of the project.
A Hazard and Operability (HAZOP) study is a structured and systematic examination of a planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment, or prevent efficient operation. The HAZOP technique was initially developed to analyze chemical process systems, but has later been extended to other types of systems and also to complex operations and to software systems. A HAZOP is a qualitative technique based on guide-words and is carried out by a multi-disciplinary team (HAZOP team) during a set of meetings.
A typical Hazard Study can have 6 stages through the life cycle of a change activity
Hazard Study 1 - Preliminary Risk Assessment
Hazard Study 2 - Identification of Major Hazards/ Risks
Hazard Study 3 - Detailed review of Hazards and Operability (HazOp)
Hazard Study 4 - Pre-Start Up Review Documentation
Hazard Study 5 - Pre-Start Up Review Site Walk around
Hazard Study 6 - Period Review of Process / Change (typically after 6 months)
The Team should ideally consist of:
- Hazard Study Leader
- Process Engineer
- Design / Project Engineer
- Maintenance Engineer
- Operations Representative
- Technical Specialist (if required)
