Flaw in NH3 Emergency Ventilation Design?
I have tried to understand the basis for the International Institute of Ammonia Refrigeration’s (IIAR) set points they recommend in one of their Technical Bulletins and one of the ANSI/IIAR codes.  Some background data to help understand this analysis: … HomeRead More »

A quick look into a Risk Assessment for a Nuclear Power Plant
My newsletter this week has generated a lot of questions and feedback, both positive and negative.  Some of you thanked me for the ideas of what should be considered when looking at the design of your safeguards as it relates to the design of your process capabilities.  Most of the e-mails were surprised that we would actually design for earthquakes and tsunamis, seeing how they are “so...

Managing your Relief Valves
I asked some ChemEs and MEs the following questions about relief valve testing. We come across some RV programs and practices that we feel fall short of following any RAGAGEPs and thought it would be helpful to hear from engineers who manage these programs on a daily basis. Here is my scenario, and their responses follow. Hypothetical Situation: I have a PSM-covered process with a refrigerant as my...

Experimental Analysis of Tools Used for Estimating Risk Associated with Industrial Machines
I found this study to be VERY INTERESTING in that I have always said you line 20 of us and show us all the same photo and ask us, one ata time, to identify the hazards in the photo.  We all know how big a spread we would lie in!!!  In this study, 31 qualitative tools used for estimation risks associated with industrial machines and which follow the ISO 14121-1: 2007 guidelines were analyzed...

DOT to Improve Safety Around Hazardous Material Loading and Unloading Operations
Data show the most dangerous part of HAZMAT occurs when it is transferred between the rail or truck. PHMSA has announced a proposed rule that would protect the public by improving the safe transfer of hazardous materials to and from rail cargo and highway cargo trucks. The proposed rule would require additional employee training and new safety requirements for motor carriers and facilities that transfer...

"Lessons Learned" potentials from Japan's Nuclear Problems
So far we do NOT have all the facts of what happened at the Nuclear Power Plant in Japan when the earthquake and tsunami hit, but we have gotten some insight into what is supposedly occurring in the aftermath of these concurrent disasters, which very well may lead to even a larger disaster with much longer impact than the earthquake and the tsunami combined! … HomeRead More »

Workers’ Perception of Chemical Risks: A Focus Group Study
Workers’ perceptions with respect to health and safety at work are rarely taken into account when considering the development of prevention programs. The aim of this study was to explore workers’ perceptions of chemical risks at the workplace, in order to investigate the prerequisites for a workplace health program. … HomeRead More »
