A study of effective mitigation system for accidental hydrogen fluoride releases
(Mary Kay O'Connor Process Safety Center, 2016)
Hydrogen fluoride (HF) is a strong, pervious gas that is a stimulus on the body, respiratory system, and skin. HF is widely used in electronics manufacturing as a polisher and disinfectant. Interest in HF increased after ...
An Overview of Worldwide Risk Tolerability Criteria for Chemical Process Industries
(Mary Kay O'Connor Process Safety Center, 2016)
Quantitative risk assessment is accepted as a process safety management tool in many countries throughout the world. Risk-based legislation is implemented by national governmental bodies. These organizations are often under ...
CSB Investigation of the West (Texas) Fertilizer Fire and Explosion
(Mary Kay O'Connor Process Safety Center, 2016)
On April 17, 2013, a fire and explosion occurred at the West Fertilizer Company (WFC), a fertilizer blending, retail, and distribution facility in West, Texas. The violent detonation fatally injured 12 emergency responders ...
Transient Large-Scale Chlorine Releases in the Jack Rabbit II Field Tests: Rainout Source Data Analysis
(Mary Kay O'Connor Process Safety Center, 2016)
Sponsored by the Chemical Security Analysis Center (CSAC) of the U.S. Department of Homeland Security, the Defense Threat Reduction Agency (DTRA) of the U.S. Department of Defense, and Transport Canada, the Jack Rabbit II ...
Make Inlet Piping and PSV One-System
(Mary Kay O'Connor Process Safety Center, 2016)
For pressure safety valves and associated inlet piping, the API recommends the non-recoverable pressure loss should not exceed 3 % of the set pressure at rated capacity flow, with some exceptions, e.g., for remote sensing ...
Mentoring New Plant and Process Safety Engineers
(Mary Kay O'Connor Process Safety Center, 2016)
Within a matter of months, I was the PHA leader and most experienced of five process safety engineers in our chemical park. Of the other five, 4 had limited process safety experience. The new engineers were of varying ...
Improving Contractor Safety Experience and Engagement
(Mary Kay O'Connor Process Safety Center, 2016)
The Role of Process History in Reducing False Alarms
(Mary Kay O'Connor Process Safety Center, 2016)
Process history is essential when reviewing operator alarm limits in the context of alarm stewardship and formal rationalization. Far too often limits are implemented on a ‘try-it-and-see’ approach that leads to higher ...
Multiscale Modeling of Buoyant Fires
(Mary Kay O'Connor Process Safety Center, 2016)
The use of computational fluid dynamics (CFD) for understanding the fire hazard potential, can be an alternative to experimental studies for the process safety industry. Detailed experimental measurements are available for ...
A Medium-Scale Cryogenic Spill Study to Estimate Vapor Formation on Concrete Substrate
(Mary Kay O'Connor Process Safety Center, 2016)
This paper presents the findings of medium-scale (5 - 15 kg) cryogenic liquid experiments on a concrete substrate which may represent an industrial grade diking material. The temperature varying thermal characteristics, ...
