Is my facility at risk? Understanding the risks associated with low burning velocity compounds
(Mary Kay O'Connor Process Safety Center, 2017)
A key factor when performing risk assessments and facility siting studies is to assess the explosion and flash fire risk of combustible fluids. There are accurate and established methods to do so when dealing with flammable ...
A Case Study: Autocatalytic Behavior and its Consideration for a Chemical Process with General application to Handling, Shipping, and Reactive Relief Design
(Mary Kay O'Connor Process Safety Center, 2017)
Autocatalysis is a generally well understood phenomenon. However, since autocatalytic molecules do not have a fixed energy release rate for a given temperature, like nth order reactions, additional considerations are ...
Plan to Fail
(Mary Kay O'Connor Process Safety Center, 2017)
The process industry has widely adopted the Functional Safety Standards IEC61508 [1] and IEC61511 [2] for achieving the Functional Safety. These standards lay the framework for achieving functional safety by considering ...
What API RP 752 Does Not Tell You – But People Will Ask
(Mary Kay O'Connor Process Safety Center, 2017)
Over the past several years, Quest Consultants Inc. has conducted building siting studies per API RP 752 for a range of facilities in the United States and abroad. This paper summarizes several of the issues encountered ...
Functional Safety Management Planning
(Mary Kay O'Connor Process Safety Center, 2017)
Successful implementation of the Functional Safety standards, IEC-61508 and IEC-61511 (or ANSI/ISA 84), begins with robust management planning. The Functional Safety Lifecycle includes activities at all stages of a process ...

Improving Barrier Effectiveness using Human Factors Methods
(Mary Kay O'Connor Process Safety Center, 2017)
The Process Industry has an established practice of identifying barriers to credit as IPLs (Independent protection layers) through the use of methods such as PHA (Process Hazard Analysis) and LOPA (Layer of Protection ...
Identifying Safety Culture Deficiencies in Facilities with the Potential for High Consequence/Low Probability Events
(Mary Kay O'Connor Process Safety Center, 2017)
One of the key underlying causes of most major accidents can be traced to deficiencies within the organization’s safety culture. The Chemical Safety Board (CSB) has directly identified safety culture deficiencies in their ...
SIL Analysis for Manufacturers of SIF Components
(Mary Kay O'Connor Process Safety Center, 2017)
Safety systems comprising of electric, electronic, and/or programmable components have been used in various industries over the years. A typical safety instrumented function (SIF) consists of a sensor to detect a process ...
Reducing Project Lifecycle Cost with an Integrated Safety Lifecycle Suite
(Mary Kay O'Connor Process Safety Center, 2017)
The international functional safety standard IEC 61511 provides the safety lifecycle as a steadfast guideline to assess and mitigate risk for manufacturing processes including refineries, chemical, petrochemical, pulp and ...
