Elements of Process Safety

The four pillars and the twenty elements of risk based process safety can be designed and implemented at varying levels of rigor to optimize process safety management, performance, efficiency, and effectiveness.

Utilizing Integrated Risk Assessment to Maximize Asset Integrity Management

Mar 22, 2010
Steve Soos
The advent of various safety standards like ANSI /ISA 84, IEC 61511, API 14C, API 580 / 581, SAE JA1011, IEC 60330 and PSM guidelines has been a good impetus in improving the availability and reliability of safety systems and processes with an objective to meet the requirements defined by OSHA, EPA...

Practical Issues with Marginally Explosible Dusts - Evaluating the Real Hazard

Mar 22, 2010
Samuel A. Rodgers
A combustible dust can be non-explosible, marginally explosible or severely explosible. With the exception of a few standards with a quantitative perspective (such as NFPA 68), most safety standards and regulations do not differentiate marginally explosible dusts from severely explosible dusts. As...

Modeling Small Releases from Tanks

Mar 22, 2010
Fredrick H. Knack
The methodologies in the chapter on “Dispersion Modeling” in the CCPS book Guidelines for Consequence Analysis of Chemical Releases, provide means for modeling outdoors releases at relatively long distances from a large source. At times it is necessary to model releases at relatively short...

Challenges in Developing and Implementing Safety Risk Tolerance Criteria

Mar 22, 2010
Walter L. Frank
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...

Property Insurance Company Evaluation of Combustible Dust Hazards

Mar 22, 2010
Henry L. Febo
This paper will discuss some of the key factors that FM Global insurance engineering representatives use in evaluating combustible dust hazards at insured locations. The information is used to develop underwriting information but more importantly, it is the basis for guidance provided for the...

Process Safety in the Face of Significant Change

Mar 22, 2010
Leslie J. May
Development of an effective process safety culture requires employees to look beyond intended performance, to their own nonconscious assumptions about process safety. When firmly in place, effective process safety culture instills an environment where employees differentiate between events which,...

High Integrity Protective System Design Using a Risk Based Approach

Mar 22, 2010
Robert J. Stack
With the update of the High Integrity Protective System (HIPS) methodology by API in 2007, Dow Chemical updated its internal work process to apply Dow's risk based work processes to HIPS design, application and evaluation. Rather than just focusing on the vessel related consequences of substituting...

Consequence Modeling of Chlorine Release

Mar 22, 2010
Prakash Amulakh Shah
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...

Strategies & Tactics for Mechanical Integrity Budget Battles

Mar 22, 2010
Daniel A. Long
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...
