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...

Geographical Societal Risk: A Useful Method for Understanding Societal Risk

Mar 22, 2010
Hans Boot
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...

Lessons Learned from Real World Application of the Bow-Tie Method

Mar 22, 2010
Steve Lewis
The benefits of using bow-tie diagrams for risk management have been realized by organizations world-wide. They provide a readily understandable visualization of the relationships between the causes of business upsets, the escalation of such event to a range of possible outcomes, the controls...

Ensuring Consistency of Corporate Risk Criteria

Mar 22, 2010
J. Wayne Chastain
The recently published CCPS text Guidelines for Developing Quantitative Safety Risk Criteria makes a strong case for corporations developing risk criteria. One topic addressed in the text is the development of criteria for use in single cause – consequence risk analysis methodologies such as Layer...

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...

Atmospheric Storage Tank Explosion Modeling

Mar 22, 2010
Jérôme Taveau
Many flammable products are usually stored in large vessels at atmospheric pressure. Ignition of an hydrocarbon-air mixture in such tanks can lead to an explosion and cause lethal casualties, as in 2006 at Partridge-Raleigh oilfield, USA, or damage the surrounding facilities and buildings. To...

Thermal Stability of Chemicals Based on Kinetics and Vessel Parameters

Mar 21, 2010
Amy Theis
Thermal stability of a chemical mixture or pure material can be evaluated using adiabatic calorimetry. Several calorimetry testing instruments and techniques will be used and compared for a comprehensive evaluation. Results from these tests can be used to determine kinetic parameters which can be...

Is It Really an Independent Protection Layer?

Mar 21, 2010
Arthur M. Dowell
Layer of Protection Analysis (LOPA) is a simplified chemical process risk assessment tool that is used to determine if sufficient independent protection layers are in place to meet an organization's risk tolerance criteria for a particular hazardous scenario. LOPA can determine how much additional...

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...

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...

HAZOP, LOPA, SIL: Be Careful What You Ask for!

Mar 21, 2010
Mike Broadribb
In recent years Process Safety Engineers have promoted the use of HAZOP to identify hazards and assess safeguards, followed by LOPA to identify if additional protection layers are necessary and, if they are to be provided using safety instrumented functions, how reliable the SIFs need to be...
