Elements of Process Safety

A subset of 44 failed spring operated pressure relief valves (SORV) from a set of over 5600 Process Equipment Reliability Database (PERD) proof tests was subjected to root cause of failure analysis (RCA). This paper reports on the findings of those 44 analyses and includes specific examples of root...

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...

Dutch legislation on safety and land use planning: Being a densely populated country, the Netherlands has extensive experience using safety regulations in land-use planning. Risk criteria have to be verified in urban development planning. Individual (Locational) Risk (IR) is easy to illustrate...

As a result of several combustible dust explosions in the past decade, the Occupational Safety and Health Administration (OSHA) initiated a Combustible Dust National Emphasis Program in October 2007. In light of the Sugar Dust explosion in February 2008, the Combustible Dust NEP was expanded in...

In a companion paper, root cause of failure analysis (RCA) was used to estimate the times to failure of a set of spring operated pressure relief valves (SORV) that were found in the fail-to-open (FTO) condition upon proof test. We now use these estimated times to failure to estimate the failure...

Risk quantification can help in understanding and managing risk. Establishing quantitative risk criteria can be a key component to risk decision-making and many companies use quantitative risk criteria, either formally or informally. The Center for Chemical Process Safety issued its guidance on...

This paper describes experience of application of the principles of process safety management within Centrica plc, an integrated energy company with operations in North America and Europe. The paper describes the key challenges for implementation of process safety requirements in this sector, the...

This research is focused on suggesting the methodology to find optimal placement for hazardous facilities and other process plant buildings using optimization theory and mapping risks. Incidents could have possible consequences from flammable gas release which can be predicted by PHAST, and the...

This paper describes the Consequence Modeling of Chlorine release from a Chlor Alkali plant as a part of Process Hazard Analysis. The objective was to carry out a Quantitative Risk Assessment Study of the liquid Chlorine storage area of the Chlor Alkali plant and build up in-house capability to...
