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. 

CPI. The first book, Guidelines for Hazard Evaluation Procedures (HEP Guidelines), eovers methods for identifying and qualitatively assessing chemical process hazards.

The CCPS publication Guidelines for Hazard Evaluation Procedures, Second Edition (Ref. 3) provides considerable information on various hazard evaluation techniques that may be employed. Evaluating hazards affecting buildings in process plants may be performed as part of a review focused specifically on the siting issue or as part of a more comprehensive review intended to identify and evaluate all facility hazards. 

This chapter provides general information for performing qualitative or quantitative risk assessments on buildings in process plants. For detailed guidance on risk assessment techniques, the user is referred to other CCPS books on this subject, including Reference 3, Guidelines for Hazard Evaluation Procedures, Second Edition, and Reference 4, Guidelines for Chemical Process Quantitative Risk Analysis. 

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).

It is difficult to identify all of the possible events and their consequences in a complex chemical processing plant without the application of systematic procedures and proper management techniques. Several hazard evaluation procedures have been developed. Most of these procedures are described in other AIChE/CCPS publications such as Guidelines for Hazard Evaluation Procedures [2,3] and Guidelinesfor Quantitative Risk Analysis [4]. Other publications on hazard evaluation techniques include [246,247].
