Once the PSSR team is satisfied with their review, a form such as Example 4-1, Pre-startup Safety Review Completion Form can be used to capture their approval for startup. For simple changes, this one-page form may be all that is required. In the case of extensive modifications, a detailed checklist of items examined by the team may accompany this form. It could include unsatisfactory findings as well as respective recommendations. If recommendations were made, these must be prioritized. Some may need to be resolved before startup others may be appropriately addressed after processing has begun. Some items reviewed by one company for extensive modifications and logged in addition to the one-page form are ... 

When using the checklist, the reviewer should decide m advance which questions would not be applicable to the toller s operations. For example, the environmental and healthand safety issues associated with a toller that will be used solely to conduct packaging will greatly differ from a of a toller that will be used to perform an organic synthesis step. 

Union Carbide (Lutz, 1995a,b) published a checklist used in their inherent safety reviews. 

The commonly used management systems directed toward eliminating the existence of hazards include safety reviews, safety audits, hazard identification techniques, checklists, and proper application of technical knowledge.

This checklist may be used to stimulate the thinking of inherent safety review and process hazard analysis teams, and any other individuals or groups working on process improvements. It is intended to promote "blue-sky" or "out-of the-box" thinking, and to generate ideas that might be usable in an existing facility or a "plant of the future" concept.

Methods for performing hazard analysis and risk assessment include safety review, checklists, Dow Fire and Explosion Index, what-if analysis, hazard and operability analysis (HAZOP), failure modes and effects analysis (FMEA), fault tree analysis, and event tree analysis. Other methods are also available, but those given are used most often. 

A safety review is recommended before any type of combustion experiment, no matter how routine. The extent of the review will depend on how common the test is and the potential for damage or injury. For tests that are commonly done with relatively little chance for damage or injury, a short informal review may be all that is required. For less common tests with a high potential for damage or injury, a more extensive formal review is recommended that could take a significant amount of time to complete. Some type of checklist should be used to ensure that all appropriate factors have been considered in the review. 

If the other elements of the PSM program have been properly implemented, particularly the MOC and Prestartup Safety Review (PSSR) elements, then the hazards analysis validation should be quite straightforward. If the first hazards analysis was a HAZOP, it is often appropriate for the subsequent analyses to use either the What—If or the Checklist methods. Doing so will save time, and will probably provide for a superior analysis because the team members will be using a fresh way of thinking and will be less likely to be bored. 

Notice. The Safety Checklist is for a preliminary safety review only and does not take the place of a complete assessment or test report(s). Other requirements may apply. Refer to appropriate standards and directives for final assessment and completion of test report(s). 

A safety review method by which What-If investigative questions (i.e., brainstorming or checklist approach) are asked by an experienced and knowledgeable team of the system or component under review where there are concerns about possible undesired events. Recommendations for the mitigation of identified hazards are provided. See also Brainstorming Hazard and Operability Stndy (HAZOP) Safety Flowchart. 

Since the original guide word HAZOP technique was developed, some companies have developed the knowledge-based HAZOP technique. It relies on the knowledge of team members to identify hazards with the design or operation of the facility, and as such can be considered as more of a safety review/checklist technique. We shall focus on the guide word technique in the remainder of this section.

A common approach for conducting a formal design safety review is to methodically work through a Design Safety Checklist. Some organizations use a generic checklist, supplemented with additional checklists for specific disciplines, such as electrical or chemical systems. For each system element, reviewers address the various forms of energy present and the steps taken to control unwanted or hazardous release. 

For these reviews, a specifically tailored Vendor/Design Engineering Review Form is to be created from sections of the General Design Safety Checklist appropriate to the task. Reports must be made available to the Safety Review Team and Project Manager. 

Drafting acceptance-safety review forms that are specific to every piece of equipment or process would be a mammoth undertaking. Nevertheless, industry-specific safety review checklists do exist and they should be used when applicable. 

The example of an Equipment Acceptance-Safety Review Form shown in Figure 1 assumes the existence of a General Design Safety Checklist that can serve as a foundation for the review process. Also, the example presumes two levels of review a preliminary review to identify items needing attention and a final sign-off.

For PSM managers, PSSR leaders, team members, and employees participating in program development or upgrade, this chapter addresses the checklist, a common and very important tool for guiding effective pre-startup safety reviews. 

An effective pre-startup safety review (PSSR) is centered on the tools a company provides to assist its staff in evaluating the safety and operational readiness of the trigger events it evaluates. One tool many companies provide is a PSSR checklist or electronic database of items to consider. This chapter examines options and considerations for compiling the items applicable to a facility. 

Depending upon a site s resources and culture, the pre-startup safety review may involve a completely electronic approach to identifying database items which apply for a specific PSSR, a partial electronic approach in which the checklist database items are customized in a document using a word processing or spreadsheet software program prior to hardcopy distribution and use, or a completely paper driven hardcopy approach. All are suitable when the persons involved in the review understand the administrative, technical, and possible regulatory-driven aspects of the facility s PSSR element.
