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 ...
Systems-focussed risk and process safety education
(Mary Kay O'Connor Process Safety Center, 2018)
Risk management and safety are at the core of performance in the process and manufacturing industries. Global studies by major consultancies show that mature risk management drives performance. That maturity considers a ...
A Risk-based Dust Hazard Analysis (DHA)
(Mary Kay O'Connor Process Safety Center, 2018)
Combustible dusts are finely divided particles that present an explosion hazard when suspended in air. Dust explosion may become more severe in a confined space, especially due to the occurrence of second dust explosion. ...
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 ...
A Hazard Identification Framework of Complex Systems
(Mary Kay O'Connor Process Safety Center, 2018)
A chemical process facility is a highly complex system. The interactions among a small group of the functions, such as process, equipment, human, organizational functions, could split, merge or couple leading to a complex ...
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 ...
Cyber Threats in the Chemical and Process Industry
(Mary Kay O'Connor Process Safety Center, 2017)
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 ...
