The first edition of the CCPS book Guidelines to Evaluating Vapor Cloud Explosions, Flash Fired and BLEVEs was published in 1994. Since that time there have been considerable advances in research for these types of explosions and fires, and hazard prediction methods have improved. The second...

In recent years, the nation has recognized that critical infrastructure protection should consider not only the prevention of disruptive events, but also the processes that infrastructure systems undergo to maintain functionality following disruptions. This more comprehensive approach has been...

Effective mechanical integrity programs are essential to assure safe operation of plant facilities. The current economic downturn is difficult and most manufacturing companies have experienced headcount reductions, early retirement programs and budget reductions. Companies are concerned with short...

Layer of Protection Analysis (LOPA) has quickly gained acceptance in the Chemical Processing Industries (CPI), and has risen to be one of the leading risk assessment techniques used for process safety studies. LOPA generally employs more rigor and science than what is encountered with qualitative...

Enabling conditions and conditional modifiers are some of the most contentious factors used in Layer of Protection Analysis. Enabling conditions are situations which must occur simultaneous with a given initiating event to allow the specific cause for a scenario to propagate to a consequence of...

The Center for Chemical Process Safety (CCPS) has designated MOC as one of the areas where metrics need to be developed. One of the issues that CCPS is concerned about is the quality of the MOCs as much as the quantity of those that have not been completed. One of the reasons is that people tend to...
