I am not sure who, where, and when this dirty little lie began, but we have been seeing an incorrect application of NFPA 70, 500.7(K) Detection System for Flammable Gases, item (3) Interior of a Building or Enclosed Space. It seems businesses are looking for any way out of having an electrically classified area and many are […]
We routinely find facility siting issues when LPG Tank(s) and Flammable Liquid Tank(s) are located in the same area. OSHA, NFPA, IFC, etc., all require a separation distance between the two (2) types of tanks. This is ALL about preventing a setup for a BLEVE, as a pool of flammable liquid finding its way under
Employee #1 was using an oxygen-acetylene torch to weld a sign to the top of a school bus in the southwestern bay of a six-bay garage. While performing this task, he sprayed water from a fire extinguisher onto a coworker walking by the bus. In retaliation, the coworker picked up a hubcap filled with liquid
This week I was in that “state up north”. It is how Ohio State fans refer to the great state of Michigan. If you did not know, the two programs are crazy rivalries in all sports. While I was conducting a Flammable Liquids Process Engineering/Code Design Review, I came across a greater risk… three (3)
Under the International Fire Code (IFC), N-Methyl-2-pyrrolidone (NMP) is not classified as a “Toxic” or “Highly Toxic” material. While NMP is legally classified as a toxic substance under environmental and labor laws (such as the EPA’s TSCA and OSHA’s Hazard Communication Standard) due to its health effects, the IFC uses a very specific, narrow definition
I’m in Grand Rapids this week working with a client on a flammable liquids process that is under the PSM TQ, but over the Maximum Allowable Quantity for “outside”. The city began adopting the IFC in 2006 and is now using the 2021 edition. I am sharing the PPT file for the management presentation/training, if
My SDS list toluene’s lower explosive limit (LEL) as 1.2% by volume, often given as:
As I noted in 2007, the #1 cause of process vessel deflagrations is the manual additions of powders to process vessels which have a flammable atmosphere. NFPA 77 covers this hazard with several solutions, yet many facilities are either not aware of these risks and solutions or simply have their head buried regarding these catastrohic
The definition of “switch loading: Switch loading is the hazardous practice of loading a low-vapor-pressure product (such as diesel or heating oil) into a tank compartment that previously contained a high-vapor-pressure, flammable product (such as gasoline) without first cleaning it. This creates a high risk of static electricity generation and explosion, as residual vapors can
Recently, I had the opportunity to help a client gain the full picture of what has to be done regarding the BULK TRANSFER hoses to unload their HHC/EHS from Tanker Trucks/ISO Containers and Railcars. Now, before we get into the specifics, I know a number of folks will fall back on the compliance position that
An explosion at a large outdoor oil storage tank at Korea National Oil Corporation Pipeline’s Yeongnam branch is preliminarily attributed to static electricity generated during a petroleum component verification process. The incident occurred at a large-scale oil storage facility housing 12 to 14 tanks, raising concerns that it could have escalated into a major disaster.
We see this often, handling, storing, and processing a Class IIIA flammable liquid, and about half will classify the area, and the other half do not. So who is right? Here is my take on the matter as I work thru the risk analysis…
