HAZOP Study Report
What is a HAZOP Study?
Orica undertakes Hazard & Operability (HAZOP) Studies on all its projects. It was also a Department of Planning requirement for the CPWE Remediation Project.
HAZOP studies have been used worldwide for over 40 years as the standard technique for reviewing process plant design and operational hazards. The procedure is set out in an Australian Standard and a Department of Planning guide.
A HAZOP study is a form of design review which concentrates on how a design will cope with abnormal conditions. It takes place after the designers have produced and reviewed process flow sheets, plant layout drawings, piping and instrumentation diagrams (P&IDs) and other fundamental design documents.
A HAZOP study is carried out by a team with wide experience, led by an independent facilitator. The focus is the project P&IDs and the facilitator asks a series of questions such as: “What happens if we get high temperatures, low pressure, no flow, etc.” to draw out ways in which hazards or operating problems may arise.
Actions are then assigned to deal with all issues likely to have a negative impact on safety and operability.
The CPWE Remediation HAZOP Study
The study was led by Jenny Polich of Sherpa Consulting and held over eight days between April and June 2010. Sessions were attended by up to ten project management, design, environmental, construction and operational specialists.
Orica is using the DTD plant formerly located at the Lednez/Union Carbide remediation site, Rhodes; and as this plant had already been HAZOP studied for that project, it would have been acceptable just to study the differences between Rhodes and the CPWE Remediation Project. However, as a "best practice" exercise, Orica and the remediation contractor, Thiess Services, elected to review the DTD plant's design from scratch.
The study generated 298 actions, most of which were relatively minor in nature, such as: installing barriers and stop signs along the internal road between the CPWE and the Feed Soil Building; overhauling the equipment prior to use at Botany; providing better access to some equipment and instruments for maintenance; increasing some pipe sizes; correcting some drawing errors; installing more cameras in the soil buildings; etc.
All of the actions were addressed before the Directly-heated Thermal Desorption plant commenced operations.
The study report of 190 pages and 30 MB in PDF format is not available on this website but is available for perusal upon request. It was submitted to the Department of Planning and the Department of Environment, Climate Change and Water (now the OEH). A three-page Summary of the study report is available below.
The study team judged only eight actions to have potentially a significant health, safety and environmental impact and they are tabulated in the Summary.
Construction Safety Study
What is a Construction Safety Study?
Orica undertakes a Construction Safety Study on all its projects. It was also a Department of Planning requirement for the CPWE Remediation Project.
The objectives of a Construction Safety Study are to identify potentially hazardous incidents during construction, to make sure controls are in place and to ensure construction is done in accordance with the design intent and specifications, and with the findings of other reviews such as Hazard & Operability (HAZOP) studies.
The procedure is set out in a Department of Planning guide.
Actions are then assigned to deal with all the safety issues likely to arise during construction.
The CPWE Remediation Construction Safety Study
The study was led by Jenny Polich of Sherpa Consulting and held on 2 July 2010.
It was attended by eight project, construction, safety and design specialists.
The study generated 20 actions. The report Summary and a table summarising the actions is available below.
All the actions were addressed before the Directly-heated Thermal Desorption plant commenced operations.
Summary of Construction Safety Study  (143 KB)
There were only two aspects of the construction that required special attention:
- Lifting and excavation activities near the Qenos office; and,
- Excavation of excavation soil building foundations near Corish Circle
The study report of 68 pages and over 6 MB in PDF format is not available on this website but is available for perusal upon request. It was submitted to the Department of Planning and the Department of Environment, Climate Change and Water (now the OEH).
Fire Safety Study
What is a Fire Safety Study?
Orica undertakes a Fire Safety Study on all its projects. It was also a Department of Planning requirement for the CPWE Remediation Project.
The objective a Fire Safety Study is to ensure proposed fire prevention, detection and protection systems are appropriate to cover potential fire scenarios that could occur during construction and operation.
The procedure is set out in a Department of Planning guide.
The CPWE Remediation Fire Safety Study
The study was led by Jenny Polich of Sherpa Consulting and held on 30 July 2010. It was attended by five project, construction, design and operations specialists.
The study generated five actions. The report Summary and a table summarising the actions is available below.
All the actions were addressed before the Directly-heated Thermal Desorption plant commenced operations.
The study report of 45 pages and over 3.5 MB in PDF format is not available on this website but is available for perusal upon request. It was submitted to the NSW Fire Brigade and the Department of Planning.
