Inherent Safety Index For Transportation Of Chemicals
(Mary Kay O'Connor Process Safety Center, 2002)
Inherent Safety can be understood as the absence or reduction of hazards (which implies lower risk) rather than low risk reached by add-on protective barriers. While the methodologies for risk analysis are well developed ...
Development of an Inherent Safety Index Using Fuzzy Logic
(Mary Kay O'Connor Process Safety Center, 2001)
The Inherently Safer Design is a concept known since 1870. However, there is a general resistance to adopt and systematically apply its principles because they are subjective. For instance: "Reduce the inventory of a ...
Benchmarking Chlorine Safety Practices in the Water and Wastewater Industry
(Mary Kay O'Connor Process Safety Center, 2001)
Less than six percent of the total chlorine production in the U.S. is used for disinfecting drinking water and wastewater. However, this segment of the industry is responsible for the operation and maintenance of more than ...
Evaluation of Styrene-Acrylonitrile Copolymerization Thermal Stability and Runaway Behavior
(Mary Kay O'Connor Process Safety Center, 2002)
Evaluation of thermal stability and runaway behavior of any exothermic chemical reaction is of great importance to the design and operation of a chemical process. The evaluation process should be based on a thorough ...
A Comparison of Simple Vapor Cloud Explosion Prediction Methodologies
(Mary Kay O'Connor Process Safety Center, 2001)
Advances in research and technology have sprouted several approaches for the prediction of vapor cloud explosion blast loads. The three simple approaches most used in industry are the TNO Multi-Energy Method, Baker-Strehlow ...
Risk Management Program: Current Issues and Updates
(Mary Kay O'Connor Process Safety Center, 2002)
This discussion will provide a discussion of the current issues being addressed by EPA's Risk Management Program under 112(r) of the Clean Air Act. The topics will include: Third Party Audits, Site Security/Counter Terrorism ...
Reducing Accident Causation in Complex Plants by Identifying Mutual Misconceptions Between Designers and Operators
(Mary Kay O'Connor Process Safety Center, 2001)
Catastrophic accidents in complex plants arise from an unforeseen combination of a number of factors. Although much effort has been invested in both improving the reliability of components, and the design of user interfaces, ...
Simultaneously Improving Safety Awareness, Safety Attitudes and Business Results – A Case Study
(Mary Kay O'Connor Process Safety Center, 2002)
“The first duty of business is surviving, and the guiding principle of business economics is not the maximization of profit, it is the avoidance of loss.” Peter Drucker Achieving acceptable business results is a priority ...
Test methods for determining explosion characteristics re-examined
(Mary Kay O'Connor Process Safety Center, 2000)
Detailed knowledge about the explosion indices is essential for safe and efficient operation. For optimal operation, explosion indices should be known under realistic process conditions, in other words under the prevailing ...
Abnormal Situation Management: a Process Dynamics Approach
(Mary Kay O'Connor Process Safety Center, 2000)
Abnormal situations are events that are outside of normal plant operating modes. It is estimated that the U. S. economy could reduce costs by $20 billion per year by avoiding abnormal situations. Modern control systems can ...
