As the project progresses, more information is available therefore, the review technique used can be different at each stage of the project. The use of various hazard evaluation techniques, such as checklist analyses, relative rankings, what-if analyses, ana hazard and operabil-... 

The following checklist contains a number of questions which can aid in identifying inherently safer process options. The list is adapted from CCPS (1993a). Other checklists, particularly the extensive checklist in Appendix B of the Guidelines for Hazard Evaluation Procedures, 2nd Edition with Worked Examjzles (CCPS, 1992) contain many questions which are related to inherent safety. 

A system checklist is useful to identify compliance problems and also tliose areas of die system diat require furdier hazard evaluation. The niediod is easy to use and can be applied to any component of a given system such as equipment, instrunientation, materials, and procedures. Tliis mediod, which produces qualitative results, must be prepared by an engineer dioroughly experienced with die system once die checklist is prepared, however, it can be used by engineers or managers who may have less tecluiical experience widi die system. ... 

The review looks for major risk situations. General housekeeping and personnel attitude arc not the objectives, although tliey can be significant indicators of where to look for real problems or places where meaningful improvements are needed. Various hazard evaluation teclmiques, such as checklists (see previous Section), what-if questions (see Section 15.5), and raw materitil evaluations, can be also used during tlie review. 

A checklist analysis is used to verify the status of a system. This analysis method is described in detail in Guidelines for Hazard Evaluation Procedures (CCPS, 1992). 

The purpose of a what-if/checklist analysis is to identify hazards, consider the types of accidents that can occur in a process or activity, evaluate in a qualitative manner the consequences of these accidents, and determine whether the safety levels against these potential accident scenarios appear adequate. The what-if/checklist analysis is described in detail in Guidelines for Hazard Evaluation Procedures (CCPS, 1992).

Five of the seven respondents who use a matrix also use chemical testing results as a data source. A similar number review the matrix during qualitative hazard evaluation studies (i.e., hazard and operability [HAZOP] studies, what-if, checklist, etc.). 

Several qualitative approaches can be used to identify hazardous reaction scenarios, including process hazard analysis, checklists, chemical interaction matrices, and an experience-based review. CCPS (1995a p. 176) describes nine hazard evaluation procedures that can be used to identify hazardous reaction scenarios-checklists, Dow fire and explosion indices, preliminary hazard analysis, what-if analysis, failure modes and effects analysis (FMEA), HAZOP study, fault tree analysis, human error analysis, and quantitative risk analysis. 

Strengthening security evaluation method using fault tree, safety checklist and other methods, in the presence of various coal mine hazard evaluation were made By theoretical data to guide the actual work, and through practical work to come back to the theory, constantly the cycle to improve mine safety values. 

Tools such as the hazard element evaluation checklist (Figure 6.3) and the energy source evaluation checklist (Figure 6.4) (TAI 1989) can be used to facilitate the development of the preliminary hazard list (Figure 6.1). The PHL, together with the PHA matrix, can then be utilized to prepare the preliminary hazard analysis worksheet. 

The Guidelines for Hazard Evaluation Procedures, Second Edition, issued by the Center for Chemical Process Safety, includes a checklist-questionnaire for chemical operations that fills 45 pages. 

To develop the risk-management strategy, start with a process hazards analysis (PHA) and review the process design and its control, operation, and maintenance practices. Select a multidisciplinary team with expertise in these areas, and use an accepted hazard-evaluation procedure, such as a hazard and operability (HAZOP), what-if, or checklist analysis, to determine how process deviations from intended...
