More LOPA Misapplied: Common Errors and How to Avoid Them

Apr 4, 2012
Karen Study
Layer of Protection Analysis (LOPA) continues to be more and more widely utilized in the Petrochemical and other industries. LOPA is a “simplified” tool, which is true relative to tools such as Quantitative Risk Assessment and Fault Tree Analysis. However, simplified does not mean simple on an...

Working Under Pressure (How do you manage pressure hazards?)

Apr 4, 2012
Dr. Angela E. Summers
Industry is increasingly moving towards utilizing High Integrity Protective Systems (HIPS) to reduce flare loading and prevent the environmental impact of pressure venting. HIPS are becoming the option of choice to help alleviate the need to replace major portions of the flare system in existing...

Societal Risk Criteria and Pipelines

Apr 4, 2012
Joan M. Schork
The discussion of societal risk criteria for the process industry began in the 1970's, led primarily by the Dutch and British governments. Most of the discussion, however, has centered on fixed facilities. The literature on the societal risk of hazardous goods transportation, particularly by...

Identification of Process Hazards in Laboratories and Pilot Plants

Apr 3, 2012
Christine Browning
The focus of most laboratory experiments and piloting operations is the development of a new, innovative chemical process or the improvement of an existing chemical process. These activities are designed to, and focus on, evaluation of the intended chemistry for the process being studied. The...

Maintain Safety Excellence in Laboratory Test Facilities

Apr 3, 2012
Amy Theis
Our laboratory contains calorimeters to characterize reactive chemical hazards and multiple different instruments to characterize both dust and gas/vapor explosion hazards. It is a challenge to ensure that each project is completed safely since a wide variety of chemicals are used. Our goal at...

Selection of Appropriate Ignition Models for Fire and Explosion Assessments

Apr 3, 2012
Anna Qiao
A release of flammable substances can result in various fire or explosion events depending on whether there is an immediate or delayed ignition. Although developments have taken place in producing fit-for-purpose ignition models, there remain significant uncertainties, including how to identify the...

Tutorial on Combustible Dust

Apr 3, 2012
Timothy J. Myers
Recent catastrophic dust explosions, the combustible dust National Emphasis Program (NEP), and OSHA proposed rulemaking, have increased awareness of combustible dust hazards in industry. This presentation provides an overview of combustible dust. The presentation will provide a summary of recent...

Explosion Hazards of Multicomponent Combustible Gas Mixtures

Apr 2, 2012
Alfonso F. Ibarreta
Laminar and turbulent premixed flame burning velocities are two parameters that are sometimes needed to evaluate explosion hazards. There is ample information in the literature regarding the burning velocities of most common ignitable gases and vapors in air. Little information, however, is...
