Numerical Modelling for Effect of Water Curtain in Mitigating Toxic Gas Release
(Mary Kay O'Connor Process Safety Center, 2018)
As the chemical industry has developed, the use of toxic substances has increased, and leakage accidents have increased. Among various substances, hydrogen fluoride (HF) and ammonia (NH3) are representative materials for ...
Prediction on Emergency Evacuation Orders Using Naïve Bayes Classification and Deep Learning
(Mary Kay O'Connor Process Safety Center, 2017)
Emergency response to chemical accidents is proceeded in order of prevention, mitigation, preparedness, response and recovery. One of the methods of response is emergency evacuation orders. In order to minimize the loss ...
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 ...
QRA Considering Multi-Vessel Failure Scenarios due to a Natural Disaster – Lessons from Fukushima
(Mary Kay O'Connor Process Safety Center, 2015)
The Fukushima accident is the largest nuclear power plant accident caused by a natural disaster, which shut off the cooling system. In this accident, an initiating event from a single unit was propagated to other units at ...
Impact of water on toxic hydrogen fluoride generation from the decomposition of LiPF6 in lithium-ion battery electrolytes
(Mary Kay O'Connor Process Safety Center, 2019)
Toxic hydrogen fluoride (HF) gas can be generated when LiPF6, a salt used in lithium-ion battery electrolytes, thermally decomposes and/or reacts with trace water. Simultaneous thermal analysis and mass spectrometry (STA-MS) ...
