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.

Lifecycle Physical Hazards of Polystyrene Foam Board

Mar 21, 2010
Atsumi Miyake
Polymer Foam Boards have been widely used for individual home and general building, from roofs and/or walls down to foundation, for example. On the other hand, these Boards have significant physical hazards, because flammable blowing agent has come to be used, replacing nonflammable CFC chemicals...

Consistent Consequence Severity Estimation

Mar 21, 2010
Angela Summers
LOPA, as a semi-quantitative analysis, often provides inconsistent results. This can be due to physical differences between units but often it is due to team's perceptual differences. Initiating event frequency evaluation using guidance tables is more consistent than consequence evaluation where...

Quantitative Risk Assessment Case Study for Organic Acid Processes

Mar 21, 2010
R. Wayne Garland
Acetic acid is not a chemical covered by the OSHA PSM regulation, as its flash point is above the 100 F threshold for flammables; however, it is by no means a non-hazardous chemical. Eastman Chemical Company has a large number of processes containing acetic acid and related organic acids, and as a...

LOPA and Human Reliability – Human Errors and Human IPLs

Mar 21, 2010
Bill Bridges
Layer of Protection Analysis (LOPA) is a simplified risk assessment method that provides an order of magnitude estimate of the risk of a potential accident scenario. Humans can be the cause on an accident scenario (the Initiating Event [IE]) or human can serve as an independent protection layer (...

A Guide to Developing and Implementing Safety Checklists: Plant Steam Utilities

Mar 21, 2010
Delmar Morrison
Steam generation is an integral part of most chemical process plants; however, the steam plant often is or can be overlooked in the area of hazard analysis. The reasons for this oversight are obvious: steam generation is considered to be an old and well understood process, and steam boiler systems...

Assessing the Burning Rate of Solid Oxidizers

Mar 21, 2010
Elizabeth C. Buc
A method for assigning solid oxidizers and products containing oxidizers to an NFPA Class was developed. The method consists of two reaction-to-fire tests: a bench-scale screening test with thirty gram piles and an intermediate-scale fire exposure test with twenty four pounds of material in...

Instrumented Protective Systems for Distillation Operations

Mar 21, 2010
Jennifer Mize
Distillation is one of the most common unit operations in the chemical processing industry. Using relative volatility as a means of separating chemicals involves adding large amounts of energy to the system at the base of the column, typically through the use of a reboiler, and then removing that...

Guidelines for Process Safety Metrics

October, 2009
Process safety metrics is a topic of frequent conversation within chemical industry associations. Guidelines for Process Safety Metrics provides basic information on process safety performance indicators, including a comprehensive list of metrics for measuring performance and examples as to how...

Explosion Prevention and Mitigation

Apr 30, 2009
Dr. Daniel A. Crowl, Kenneth Bloch, Paul Amyotte
The analysis, prevention, protection and mitigation of fire, explosion, and reactivity hazards continue to be important to the loss prevention community. This session includes papers that identify, characterize, or offer design and operational guidance on fire, explosion and reactivity hazards...

Case Histories and Lessons Learned

Apr 29, 2009
Delmar Morrison, Mark Kaszniak, Scott Davis
Reviews of process safety incidents and near misses provide valuable learning opportunities. Papers dealing with incidents, near misses, and the lessons learned are presented. Please Note : Case Histories and Lessons Learned -- Spring Meeting 2009 includes the following recorded presentations: ·...

Risk Criteria

Apr 29, 2009
Fred Henselwood, Wayne Chastain
The new CCPS Guidelines for Establishing Risk Criteria will be published in mid-2009. This session includes papers regarding the development and application of risk criteria to improve a company's risk profile. Topics also include experience and examples with risk apportionment, international...

Applications of Risk Analysis Techniques

Apr 29, 2009
Angela Summers, Fabien Fouillen, Peter Moore
Hazard identification and risk assessment continue to be a critical part of the process safety efforts in process plants. Papers highlighting methods, tools and examples of successful application or lessons learned from misapplication in a plant environment are presented. Please Note : Applications...

Audits, Inspection and Regulation

Apr 29, 2009
David Heller, Dr. Timothy Myers, Lisa Long
In the past few years, we have seen renewed emphasis on PSM through OSHA’s National Emphasis Programs and Homeland Security new Chemical Security’s regulations. This session contains papers that discuss regulatory programs in the U.S. and internationally, and companies strategies for complying with...
