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...

Improving the Performance of Established PSM Programs

Apr 2, 2012
James A. Klein
Many facilities have now implemented and maintained PSM programs for 20 years or more, but these facilities continue to have sometimes serious incidents and injuries suggesting a continuing need to improve their PSM performance. Of course, new requirements are often added to upgrade PSM programs,...

Integrity Inspection of In-Plant Underground Piping

Apr 2, 2012
Everett Johnson
Underground piping inside plant boundaries is frequently out-of-sight, out-of-mind. While there exists a wide body of knowledge, mature technology, and established techniques for inspection of cross-country underground pipelines, and even above-ground in-plant piping, the converse is true for...

The CCPS Reactivity Evaluation Software Tool

Apr 2, 2012
Edward M. Davis
Incidents involving uncontrolled chemical reactions continue to result in injuries, fatalities and economic loss and harm in industry. These incidents are often the result of not identifying or understanding the chemical reactivity hazards involved in storage, mixing or processing operations. The...

Avoiding Common PHA Mistakes

Apr 2, 2012
Glenn Young
OSHA's National Emphasis Program (NEP) on refineries has concluded. The two most cited elements of the Process Safety Management standard (PSM - 1910.119) in the NEP were Mechanical Integrity and Process Hazard Analysis (PHA). [1] This session will focus on common problems in PHA and how to avoid...

Safety System Impairments and the Need to Manage Peak Risk

Apr 2, 2012
David K. Lewis
The catastrophic incident which occurred at Bhopal is often referenced with respect to inherent safety issues. Did intermediate chemicals need to be present? Should the neighboring community start at the fence line? Although likely not as important as the above fundamental considerations, the...

ìWell the Team Has Met and Completed the PHAÖ.Now What?î

Apr 2, 2012
Dewana Tarpley
Learning from the experiences and expertise of others has long been recognized as a valued process when completing PHAs. The gathering of a multi-disciplinary review allows facilities to succeed in a path of continuous improvement by evaluating the current and future state of the process based on...

Implementation of a Highly Toxic Materials Management Program

Apr 2, 2012
Ravi Ramaswamy
Process Safety Management (PSM) is defined as the application of management systems and controls (programs, procedures, audits, evaluations) to a manufacturing or chemical process in a way that process hazards are identified, understood, and controlled so that process-related injuries and incidents...

Retired and Dangerous

“Planning not to retire is simply not a viable retirement strategy.” — Catherine Collinson, Transamerica Center for Retirement Studies The Hazard Identification and Risk Assessment (HIRA) process is an important component of a facility's strategy to managing the risks associated with process...

Stability Analysis of Safety Valve

Mar 22, 2010
The stability for a safety valve was investigated by experiments and analysis. It was found that the dynamic instability was caused by the interaction effect between the pressure wave propagation through the inlet pipe and the valve disc motion. This dynamic instability is mitigated by the...
