Risk-Based Approaches to PSSR

TWO EXAMPLES OF USING A RISK-BASED APPROACH TO PSSR DESIGN... 

Compare this example to an existing PSSR program. Are there areas where one is more conservative than the other from a safety standpoint Does one require tighter management control than the other Consider the culture and resources available and identify aspects which could be addressed in a way that may enhance compliance or display the organization s philosophy toward PSSR and PSM in general. Examples of the associated PSSR short form and PSSR long form referenced in this example are provided in Chapter 4 -. 4 Risk Based Approach to PSSR. 

Detailed examples for your PSM manager and PSSR team leaders to consider are provided in Chapter 4 - A Risk-based Approach to Pre-startup Safety Review and throughout the book. 

This is where a facility may apply a qualitative risk-based approach to the PSSR. The first decision to be made is based upon the unique characteristics of the specific situation - the change or the new facility/major modification or other trigger event. 

This book introduces the basics of applying a risk-based approach to pre-startup safety review. Specific aspects of trigger events may be examined for selecting the type of PSSR suitable for a given event. 

In regard to how complexity affects the PSSR team composition, the selection of the PSSR short-form approach using a risk-based approach means a minimum team is required. 

Here is where the risk-based approach necessitates a first look at the nature of the trigger event. By following some of the guidelines in Chapter 4, the type of PSSR to design is relatively easily divided into simple or complex - that is, a short form or a long form respectively. However, when the PSSR long form is indicated, there are numerous decisions to make about the pre-startup safety review s needs. 

The term complex merely indicates that the PSSR will require some level of special planning and effort due to its unique risk-based characteristics or novelty to the site. Whenever we use the terms complex PSSR or long-form PSSR, they indicate a more customized and sometimes more time-consuming approach to verifying readiness for startup. We will see this as we examine PSSR team makeup and review planning examples.
