Gas Piping and Equipment Commissioning Risks "10 Key Things Everyone Should Know"

Mar 23, 2010

John R. Puskar

There have been a number of devastating incidents related to natural gas piping system and the start-up and commissioning of equipment. It's very rarely that an incident occurs when equipment is at the ready and in some normal operating routine. The vast majority of incidents are directly related...

Using Root Cause Failure Analysis Results to Estimate Failure Rates and PFDavg for Spring Operated Pressure Relief Valves

Mar 22, 2010

Julia V. Bukowski

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...

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...

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...

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...

The Use of Quantitative Risk Assessment to Site Temporary Trailers and Portable Buildings

Mar 22, 2010

James M. Hudson

The American Petroleum Institute (API) developed Recommended Practice (RP) 753 to provide guidance for siting portable buildings in petrochemical processing plants. It identifies analysis methods for siting portable buildings and provides siting distance guidance for vapor cloud explosion hazards...

Semi-Automated Work Process for Capturing Relief Valve Proof Test Data to Support Failure Rate Analysis

Mar 22, 2010

H. W. Thomas

Chevron and Air Products have both leveraged an initiative by the Swan Associates test shop that ensures compatibility of their internal software used to manage their operations with the CCPS PERD software, designed to support value added analysis. The work process involves “as found” proof test...

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...

Occupational Safety and Health Administration's Experience with the Combustible Dust National Emphasis Program

Mar 22, 2010

Sanjeeva M. Kanth

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...

Update of “Guidelines to Vapor Cloud Explosion, Pressure Vessel Burst, BLEVE and Flash Fire Hazards”

Mar 22, 2010

Quentin A. Baker

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...

Use of Multiply Non-Destructive Examination (NDE) Methods in Life-Cycle Evaluation of Process Equipment and Systems

Mar 22, 2010

F. Russ Davis

Equipment reliability is essential to the safe operation of process equipment. The health of process equipment must be analyzed by competent personnel using proper methods to identify current damage and predict anticipated life. The use of proper testing and inspection methods is basic to...

A Resilience Assessment Framework for Infrastructure and Economic Systems: Quantitative and Qualitative Resilience Analysis of Petrochemical Supply Chains to a Hurricane

Mar 22, 2010
