Incident investigations are a part of process safety management. In investigations, lessons are learned as to how inherently safer technology could have prevented or mitigated the results. How can these learnings be disseminated such that future incidents in similar processes are avoided ... 

Most or the incidents described were the result or not rollowing good engineering practice. Some violated the law, and many more would if they occurred today. In the United States, they would violate OSHA 1910.147 (1990) on The Control of Hazardous Energy (Lock Out/Tag Out) and the Process Safety Management (PSM) Law (OSHA 1910.119, in force since 1992). which applies to listed chemicals above a threshold quantity. The PSM Law requires companies to follow good engineering practice, codes, industry consensus standards, and even the company s owm standards. OSHA could view failure to follow any of these as violations. 

Process Safety Management (PSM) is the application of management systems to identify, understand, and control chemical and manufacturing process hazards and to prevent process-related injuries and incidents. 

History of previous incidents. Frequent incidents, especially serious ones, indicate a breakdown in process safety management systems. They also indicate that the facility may be more likely to have additional incidents, unless the underlying causes have been determined and specific actions have been implemented to prevent their reoccurrence.

Bhopal and a series of other major incidents underscored the need for increased attention to process safety management OSHA began to develop a standard that would incorporate these principles. A proposed standard was published in 1990. Additionally, the Clean Air Act Amendments (CAAA) of 1990 required OSHA to promulgate a standard to protect employees from the hazards associated with releases of highly hazardous chemicals, including reactive chemicals. 

Inadequate process safety management practices are often cited as the cause of reactive incidents, as discussed in Section 3.0 (Table 4). Incident data underscore the critical importance of successfully implementing the following key elements throughout the life cycle48 of a manufacturing process ... 

On the other hand, there are a number of elements of fire prevention that overlap with elements of other programs. For example. Incident Investigation, Management of Change (MOC), Process Safety Information (PSI), and Process Hazard Analysis (PHA) input required for fire prevention can be derived from these same elements of the Process Safety Management (PSM) program. 

Most facilities already have an established Incident Investigation Program as part of the Process Safety Management program. These existing Incident Investigation Programs should incorporate fire prevention requirements. 

Like all of the elements of process safety management, the incident investigation element continues to evolve. The AIChE Center for Chemical Process Safety assists this evolution hy providing interested parties with information to help them in safely operating process facilities. To this purpose, CCPS and the contributing authors offer this second edition of the Guidelines for Investigating Chemical Process Incidents. 

Incident investigation is only one of the many elements of a process safety management program, but it plays an essential role in identifying overall management system weaknesses on a continuous basis.
