A tradesman was nearly sprayed with heavy fuel oil while attempting to change the suction strainer on a pump. He was removing the securing bolts from the strainer when the incident occurred. Initial findings indicated that the suction and discharge valves were not isolated and the system contained a tank header pressure of 80-100Kpa at a temperature […]
There is one PSM/RMP task that continues to cause problems and is still heatedly debated within process safety circles. In all of the PSM/RMP requirements from OSHA and EPA standards, Line Break/Process Opening is the one area where there is no Recognized and Generally Accepted Good Engineering (RAGAGEP) for how the task is to be
In the past few decades many things have changed in the world of Hazardous Materials and many of these changes DIRECTLY IMPACT our process safety efforts and our PSM/RMP compliance. The debate will continue as to where DOT stops and OSHA begins when it comes to compliance coverage regarding loading and unloading Hazardous Materials, but
Steaming railcars and tanker trucks is a very common practice in many industries; however, the hazards of doing so it not widely known nor understood. Much like we cover “TOO MUCH TEMP” in our process hazards analysis, a similar analysis may be called for to analyze the practice of applying a heat source (e.g. steam
Earlier this year I wrote about the risks in using “truck drivers” as your HAZMAT Attendant, as well as using the carrier’s hose for your loading/unloading activities. I have also posted several “Safety advisiories” from state and federal agencies regarding the mis-use of transfer hoses. Many of you appreciated my bluntness and brining the concerns
Earlier this year I wrote about the EPA Safety Alert regarding having high expectations of an Excess Flow Valve being a reliable safeguard to stop an uncontrolled flow of a HHC/EHS. This article is another example of how these valves should NOT be considered a safeguard and most certainly should NOT be the sole layer
In processes handling flammable liquids, “flange jumpers” (also known as “bonding jumpers”) are critical safety components designed to maintain electrical continuity across piping joints. Since piping systems are often coated, gasketed, or subject to corrosion, a standard flanged connection may not provide a sufficiently low-resistance path to ground.
My hi level interlock just tripped on my vessel – can I count this trip as the scheduled quarterly/annual PM test? This question is maybe in the top 10 questions we get from PSM/RMP clients and friends and without a doubt one of the top 5 MI questions of all time. There is no argument
12/13/12 – I uploaded the full video (1:45) to my YOUTUBE account rather than the members’ area. This full version includes a 2nd view from a different camera and shows the full impact and size of the explosion and the tank fires resulting from the blast. WARNING! This video will be UPSETTING to many, especially the
If you spend any time around Anhydrous Ammonia, you know how easy it is to detect its presence; however, if you have ever tried to find the leak causing the issue, it can be extremely difficult. One of the most common, simplest, and cheapest methods is using sulfur (or sulfur) sticks. These have been around
UPDATED FM Data regarding Contractors and Hotwork… 3.1.8 Outside Contractors Many hot work operations are performed by outside contractors, these include cutting, welding, joint soldering, paint removal, reroofing, etc. The tendency is to relax rigid procedures for contractors assuming they know their jobs. However, this practice has produced a discouraging loss history. Hot work by itself is
Not many know this dirty little secret about overpressure protection on ASME-coded vessels (formerly called “code case 2211”), but I will let the cat out of the bag… Not all ASME pressure vessels have to have a pressure relief device, and I am not talking about those very small vessels, but any size vessel. No,
