As these flammable refrigerants take hold around the globe, the IFC, in its 2024 edition, has specified storage quantities in… Membership Required You must be a member to access this content.View Membership LevelsAlready a member? Log in here...

Many of us have struggled to understand the differences between OSHA’s Hazard Categories and the other codes that still use Hazard Classes. Here is a helpful table that can help clarify things….

A jury trial is set for the former employee charged in the February home explosion that killed one volunteer firefighter and injured 13 more people. He is facing a felony charge of involuntary manslaughter and three other misdemeanors relating to the unlawful transfer, release, maintenance, and control of liquid petroleum gas. The worker, 67, has…...

As we have discussed many times, UNLOADING/LOADING Hazardous Materials to/from a bulk DOT container is often times one of the highest risks on a plant site. And when the hazardous material is a liquefied compressed gas, the risks escalate quickly! Two of the more common liquefied compressed gases are LPG and NH3, which fall under…...

For those who deal with these “hazardous materials storage cabinets,” we have seen some new design requirements over the past couple of code cycles. A lot of codes began requiring “self-closing” doors on these cabinets; however, we can go back to the 2012 edition of the IFC and find this requirement. And now the IFC…...

A few years ago, I warned about the huge push to make flammable refrigerants easier to manage in the name of “global warming.” As a safety professional, this shift is alarming. Never in my career have we considered a burning rate of 10 cm/s as a means to lessen the risk associated with a flammable…...

The report indicated that the driver of the refrigerated truck had poor safety and legal awareness. He allowed eight female workers to ride in the truck, which carried packaged beef with dry ice. The dry ice sublimed into carbon dioxide gas, which rapidly filled the confined space inside the truck…. Membership Required You must be...

As we have discussed, the Chemical Safety Board (CSB) issued a Safety Study (CSB Safety Study: No. 2024-01-H, Remote Isolation of Process Equipment) discussing the untapped advantages when Remote Emergency Shut-Off Valves are used in hazardous processing.  I have written about these requirements for all types of hazardous materials; this post is for Flammable Gases…...

Those who follow my accident posts are well aware of my crusade to help everyone understand the LIMITATIONS of our atmospheric monitors. Just this year, I did my 2-day PRCS training course for a well-known petrochemical business and was challenged on the limitations of the LEL sensors on these devices. During the lunch break, several…...

As many of you know, I have a love of bollards. This love has come over many years and many accidents where I have seen them protect a critical asset and PREVENT a serious event. This is a new county building built near my home, and when I drove by, I had to take a…...

If we spend enough time in chemical plants, we will encounter a widespread, albeit severe, human failure regarding a “safety-critical instrument.”  I am referring to the IMPROPER placement of personal gas monitors.  Nine times out of 10, where do we find these personal gas monitors on the worker’s body?  I am betting your experiences are…...
