At 10:15 a.m. on February 12, 2015, an employee was working from the elevated basket of a manlift, installing sheetrock in an area of the job site where water piping was undergoing pneumatic testing, at 130 psi. At the same time, another contractor was performing a compressed air leak test. An 80-pound section of the […]

This document is a gem to have if you’re in a role that requires the use of multi-gas detectors such as those used for entry into permit-required confined spaces and check an area before Hot Work begins. It has been around since 2016 and I have used the information in it for years in my
In this picture from the Jack Rabbit, we can see the Liquid NH3 that has pooled under the container. This occurred under 95F temperature with a high wind speed, which blew the cloud away from the pool making the pool visible. The picture below was taken 10-seconds after the container was empty. Also, notice the
The data from the Jack Rabbit tests done over the past decade is immense and exceptional learning tools. I always make sure my students, whether it be a HAZMAT responder class or a Process Safety course, fully understand how Vapor/Gas Density impacts us in a LOPC event. Using Chlorine and Ammonia, the contrast is stark
This video is from 2013, but I thought they did such an excellent job explaining 1234yf and how we went from 134a to this new refrigerant I should share it for context. I have been very hard on the suppliers of this new Low GWP refrigerant over the years and this video sums up the
Question: Would you/Do you permit 2-way radios, and their attachments, that do NOT carry a rating for HAZLOCs (Class I, Div 1/2) to be used inside a Level A suit? Recently I was asked to help a client in the great state of NM with their emergency response capabilities. Our first step was to assess their
At approximately 7:00 p.m. on November 15, 2006, Employee #1 was a process operator at the Chlorine Liquefaction Unit, Block A-19. He was preparing to bleed off chlorine on a process line, to clear the line for maintenance work. The valve handle indicated that it was in a CLOSED position. Employee #1 opened the cap to
At approximately 2:30 p.m. on March 2, 2011, six workers were employed as milling or planing machine operators at a corn and flour milling facility in Lincoln, NE. A chlorine leak was detected in the chlorine room, so the milling superintendent and a miller/operator entered the chlorine storage room and closed a manual valve on
This is a lesson in why “Unloading” any hazardous material is such a high-risk task. In this incident, the facility had their connections locked (but the driver was told the combination), they were using the driver’s procedure, the connections were properly labeled, the driver could not see the tank he was pumping to, the company
At approximately 5:00 a.m. on February 8, 2014, Employee #1, a K2 Pure Solutions operator, was depressurizing a line that contained chlorine gas. Two attempts were made to depressurize the line. The first attempt resulted in a small chlorine release and employees having to evacuate to shelter and the second attempt resulted in the employee
