Thermal Safety of Ionic Liquids

Apr 2, 2012
Ryan J. Hart
During the past decade, research and development in ionic liquids has grown tremendously. Targeted applications for ionic liquids include replacement of volatile organic solvents in separation processes, organic chemistry, microelectronics, and many more. Ionic liquids are simply low melting...

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...

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...

When MOC Meets LOPA: A Quantitative Assessment of the Impact of Errors in MOCs

Apr 2, 2012
Rainer Hoff
Layers of Protection Analysis, "LOPA", has become a popular tool for conducting semi-quantitative risk assessments, in the chemical process industries. A key concept is that of "Independent Protection Layers", whereby subsequent layers are intended to mitigate adverse events that were not mitigated...

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,...
