As many of you know, I stopped using 1910.106, OSHA’s flammable liquid standard, nearly 20 years ago. Instead, I use the Internation Fire Code for all my Hazardous Materials, especially flammable liquids and gases. This code provides some excellent design/requirements for unloading flammable liquids, which can be one of the HIGHEST RISKS on a plant […]
Since 2012, the IFC has required special signage at each Flammable Liquid Truck/Railcar unloading station. This signage is intended to reduce “tank overflow” events (e.g., Loss of Primary Containment (LOPC) events). Here are the requirements:
On July 7, 2020, an employee, 33, was standing on a ladder pouring caramel color from its storage container into a 500-gallon batch of rum that was being made in a 1250-gallon tank of alcohol (type unknown). As the employee began to pour the caramel, a flash occurred due to an electrostatic discharge contacting the
On June 8, 2022, piping at an LNG Terminal failed, resulting in an explosion and fire. The explosion and fire occurred entirely within the fenced boundaries of the facilities. The facility immediately shut down its operations and notified first responders. With assistance from local fire departments, the fire at the terminal was brought under control
Table 5704.4.2—Outdoor liquid storage in closed containers and portable tanks (see below) is often referenced when a business wants to store flammable liquids outside the main building. I wanted to take a second to explain the application of that table to those on the EHS team who may not be experienced with the OH Fire
Lots of folks find it hard to believe when I discuss Minimum Ignition Energy for flammable vapors/gases and Combustible dust. When we get “shocked” by a door handle in the wintertime, and we can feel it, that is around 10-15 mJ. Most common flammable gases and vapors now have MIE’s less than 1.0 mJ. Watch
I teach about a dozen flammable liquid courses annually, and it is one of my favorite courses to teach, as I love the technical side of hazardous materials. And my course always starts with a discussion around the 1st step in making a flammable liquid a hazardous material… FLASH POINT. And over the 30+ years,
The investigation found that they were processing hand sanitizer bottles by shredding them and separating the plastic from the hand sanitizer. During this process, a spark was created from the machine, which initiated a minor explosion and fire. The business has refuted the fire chief’s official account, saying, “There was no explosion at the site.“
This week, I shared some pictures of a setup I encountered last year in an audit I conducted at a manufacturing facility. This sole department was using metal trash cans as ” safety cans,” while the rest of the facility was using FM/UL “approved safety cans” for their “dirty rags” storage. The sight of this
UPDATED 7/26/2024 with drone images, fatality count, and preliminary investigation findings Two (2) of the factory’s 219,000-liter (57,850-gallon) tequila vats ruptured, triggering a fire in three (3) other tanks. One 500,000 liters (132,086 gallons) suffered a HIT and traveled nearly 700′, landing in a residential area. The explosion within the plant killed seven (7) workers;
Without question, the #1 question we receive regarding Hazardous Locations is… When do I need one? With flammable liquids (e.g., FP<100F) it is easy to perform the evaluation. But what if my flammable solution is a CAT 3 or 4 (i.e., Class IIIA or IIIB)? As the title says, not all flammable solutions require us
On September 13, 2007, a subcontractor was implementing a hot tap into a carbon steel pipe. The explosion was caused by the heat from the acetylene torch kindling the residual vapor inside, attaching to the polyvinylchloride (PVC) piping. Shrapnel pieces were blown up to 100 feet outwards due to the force of the explosion. The
