MOC Impact Workflow to Ensure that Relief Systems PSI is Updated with Changes
(Mary Kay O'Connor Process Safety Center, 2015)
The Process Safety Management (PSM) Standard requires that covered facilities manage change through the Management of Change (MOC) program. A robust MOC program effectively identifies and analyzes changes. Observation has ...
CCPS’ Vision 20/20 – Delivering Great Process Safety Performance
(Mary Kay O'Connor Process Safety Center, 2015)
Vision 20/20, developed by the Center for Chemical Process Safety (CCPS), looks into the not- too-distant future to describe how great process safety is delivered when it is collectively and fervently supported by industry, ...
Implementing Safety Instrumented Burner Management Systems: Challenges and Opportunities
(Mary Kay O'Connor Process Safety Center, 2015)
Implementing a Safety Instrumented Burner Management (SI-BMS) can be challenging, costly, and time consuming. Simply identifying design shortfalls/gaps can be costly, and this does not include costs associated with the ...
Interpersonal Relationships among University Safety Professionals: The Impact of a Safety Departmentf
(Mary Kay O'Connor Process Safety Center, 2015)
Forming strong interpersonal relationships enables an organization or individual to achieve more favorable outcomes. The objectives of this study were to examine the frequency of interpersonal interactions among safety ...
Vapor Cloud Explosion Live Test and Data Analysis Development Program
(Mary Kay O'Connor Process Safety Center, 2015)
Vapor Cloud Explosions (VCE), an ever-present threat to the petroleum refining industry, create hazards to employees, equipment and production capabilities. To mitigate the effect of these hazards, effective designs for ...
A Numerical Approach to Determining Flammability Limits of Hydrocarbon Process Fluids
(Mary Kay O'Connor Process Safety Center, 2015)
Intrinsic to the computer modeling of explosions and fires is the concept of flammability limits. Conventionally, the term “flammability limit” is defined loosely as the concentration limits beyond which flame propagation ...
OPTIMI – A Novel 3D Computational Tool for Gas Detector Optimisation
(Mary Kay O'Connor Process Safety Center, 2015)
An efficient approach to optimise the number and location of gas detectors plays a role of paramount importance when gas leak identification at early stage is required. The novel approach relies on the set covering problem ...
Quantification of the Thermal Hazard from Metallic and Organic Dust Flash Fires
(Mary Kay O'Connor Process Safety Center, 2015)
An in-house constructed nominally 20-L flash fire apparatus was used to evaluate and compare the flash fires fueled by an organic dust (non-dairy coffee creamer) a metal dust (aluminum) and a flammable gas (methane). ...
Pressure Relief Sizing of Reactive System using DIERS Simplified Methods and Dynamic Simulation Method
(Mary Kay O'Connor Process Safety Center, 2015)
Incidents involving uncontrolled chemical reactions continue to result in fatality, injury and economic loss. These incidents are often the result of inadequate pressure relief system designs due to a limited knowledge of ...
Evacuation Simulation of Confined Spaces in Petrochemical Facilities
(Mary Kay O'Connor Process Safety Center, 2015)
With the development of petrochemical industry, confined space evacuation has been a major safety issue due to the potential fatalities and injuries caused by inadequate emergency responses. In this work, two existing ...
