INTRODUCTION
The Certified PHA HAZOP Leader Training program would offer extensive instructions that include the methodology of carrying out a HAZOP study and identifying where PHA methods lie into the whole process safety management work process.
Out of all the other approved methods of Process Hazard Analysis (PHA), HAZOP study is the most extensively used method in the major industries like oil and gas, petroleum, chemical, nuclear, etc. It is a systematic team-based technique used for major process modifications, designing a new project or process, periodic review of an existing operation, and much more. This is why the HAZOP study is known as the most effective studies for the identification and analysis of risks in hazardous operations and operability problems.
-
COURSE OBJECTIVES
By the end of the course, you‘ll be able to:
-
- Implementing Failure Mode and Effect Analysis (FEMA) method
- Supplementing your brainstorming analysis using hazards checklists
- Identification of best circumstances and situations for using each technique
- Acquainting yourself with each technique by participating and leading in practice analysis activities
-
COURSE AUDIENCE
This course is made for :
-
This program is suitable for those individuals who are responsible for leading PHA studies in their organizations, like, engineers.
-

HAZAN
- The stages of hazard analysis Some of the targets or criteria
- Risks to employees – The Fatal Accident Rate (FAR) – To convert FAR to hazard rate
- Risks to the public
- Remove first the risks that are cheapest to remove!
- Estimating how often an incident will occur
- Examples – HAZAN
-
- 1 Relief valves
- 2 Simple trips
- 3 Frequent demands on a trip
- Two protective systems: parallel or in series?
- Fault trees
- Pitfalls in hazard analysis
- Data may be inapplicable or outdated
- Data affected by maintenance policy
- The impossibly low fractional dead time
- More about common mode failures
- A summary of the main sources of error in hazard analysis
- Objections to HAZOP and HAZAN
-
- Insufficient data are available for meaningful calculations
- The models of the accidents are oversimplified and they bear little relation to reality
- Human errors, including management errors, cannot be allowed for
- The resources required are excessive
- It cannot be applied to industrial disease
- It is often done badly
- HAZAN example – (Instructor led workshop)
