The key steps in the audit process are outlined according to preaudit ac tivities, audit activities, and postaudit activities in Fig. 26-12. These activities are described in detail in Guidelines for Auditing Process Safety Management Systems (CCSP, 1993) and will be only briefly discussed in this sec tion. 

Audit (Process Safety Audit) An inspection of a plant or process unit, drawings, procedures, emergency plans, and/or management systems, etc., usually by an independent, impartial team. 

Despite these potential benefits, there are possible problems associated with the use of generic safety audit systems. Questions that need to be considered in the case of such standardized audits include ...

The first task, hazard identification, is crucial in process system safety analysis, because the effectiveness of the other two tasks depends on it. The traditional methods for identifying hazards during the 1960 s (including process reviews , codes of practice , checklists , and safety audit ) were no longer considered adequate in the 1970 s. There was a need for a technique which could anticipate hazardous problems, particularly in areas of novelty and new technology where past experience was limited.
