In April, 2011, an ammonia leak at a large warehouse where anhydrous ammonia is used in the refrigeration system in a cold storage building. In this incident, one worker was burned on the arm from the escaping gaseous ammonia. An estimated 3600 pounds of ammonia evaporated into the air during this incident. As part of the […]
Back in January 2012 I posted a study that was conducted in conjunction with the Faculty of the Undergraduate College of Integrated Science and Technology, James Madison University, Virginia; the Harrisonburg (VA) Fire Department; and the Harrisonburg (VA) Rescue Squad HRS. This week I present to you a hands-on “study” done by the “HAZMAT Guys“,

Following up on a 2012 post about complying with 1910.95(j), I wanted to share a working example of how I document my “hearing protector attenuation” evaluation. I think the example speaks for it’s self, but if you need a reference as to what this exercise is meant to accomplish please refer to my 2012 post Hearing
I love science, especially when we can relate it directly to industrial safety. We all know the power of pressure, but the power of a vacuum is often lost.
One of the most often asked questions in my Process Safety training courses is… “What do you mean when you say Layers of Protection?” So I have made this very simplified powerpoint presentation to provide a visual of how “Layers of Protection” are effective and how they BECOME INEFFECTIVE. This safety principle is most often mentioned in process
