The Effect of the Routine/Non-Routine Nature of Tasks on Serious Accident Rates
(Mary Kay O'Connor Process Safety Center, 2000)
An accident model and a model of human cognition were combined to create a hypothesis about a major source of causation for accidents at a manufacturing site. This led to a definition of a routine/non-routine task or ...
Testing the Effectiveness of Shelter-in-Place for Alternative Release Scenarios
(Mary Kay O'Connor Process Safety Center, 2000)
The recent implementation of Risk Management Plans by many facilities has heightened public awareness of the need for protection from accidental chemical releases. Shelter- in-place is the protective measure of choice for ...
Inherently Safer Plant Equipment Layout to Minimize the Hazards from Vapor Cloud Explosions
(Mary Kay O'Connor Process Safety Center, 2000)
It is possible to minimize the blast loads from a potential vapor cloud explosion by careful examination of equipment layout and structural designs. These inherently safer facilities have the advantage of reducing the ...
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 ...
Analysis of the EPA RMP* Info Database
(Mary Kay O'Connor Process Safety Center, 2000)
EPA’s risk management program requires regulated facilities to submit a risk management plan, which includes the 5-year accident history of the facility. EPA has compiled the risk management plan in the RMP*Info database. ...
IMPROVING SAFETY PERFORMANCE IN THE NEW MILLENNIUM AND THE ROLE OF UNIVERSITIES
(Mary Kay O'Connor Process Safety Center, 2000)
Although the safety record of the process industries is good, almost all the accidents that occur need not have occurred. Often, after an accident or near-miss, we neglect opportunities to learn and remember: • Accident ...
Droplet Size Distributions of Heat Transfer Fluid Aerosols in Air
(Mary Kay O'Connor Process Safety Center, 2000)
Heat transfer fluids are widely used in the chemical process industry and are available in a wide range of properties. These fluids are flammable above their flash points and can cause explosions. Though the possibility ...
Performance vs. Prescriptive Fire Protection for the Offshore Industry
(Mary Kay O'Connor Process Safety Center, 2000)
Most companies have standards for fire protection on offshore installations. These standards typically are prescriptive in nature and require that fire protection be installed, generally, without regard to the actual hazard. ...
Extrinsic Safety Systems
(Mary Kay O'Connor Process Safety Center, 2000)
Everything dies, breaks, or runs out of gas. Everything. This is especially true for extrinsic safety systems. In contrast to intrinsic safety in which the process is designed to be inherently safe (1), extrinsic safety ...
