Suggested Safety Reviews During a Project Life

The magnitude of a change to the facility or its operation determines the level of safety review needed. A like for like replacement of pipe will typically not require a process hazard analysis. The substitution of a pipe of different material and routed to a new location may warrant a What-If review. 

Since a multitude of different changes may occur at a facility, the company s Management of Change procedures should define the type of process hazard analysis required by the change and these requirements are beyond the scope of this guideline. 

Once it is determined that a HAZOP or What-If review is necessary for the change, reference should be made to these guidelines. 

Three areas of preparation are needed for a review to take place - the location, administrative support, and documentation. 

The location of where a review is held should be determined by where the most amount of information and personnel knowledgeable in the facility design and operation are located. Typically new designs will be have the data at the engineering contractor s offices and the reviews will be held there. For existing facilities, the review is usually held at the facility itself.
