Four (4) people were killed, and several others sustained injuries after an LPG tanker crashed into a toll plaza and erupted in flames. The tanker was carrying around 18 tons of liquefied petroleum gas (LPG) and lost control before crashing into the toll plaza. According to the police, the tanker first hit a road divider…...
The primary difference between a pipe vent and a pipe drain lies in their location and function within a piping system. In both industrial process piping and residential plumbing, they serve as essential controls for pressure and fluid management….

On August 28, 1992, a cryogenic tank ruptured in Hokkaido, Japan, and is a textbook case study in the catastrophic consequences of completely isolating a cryogenic vessel. The explosion occurred in the middle of the night at a food processing factory. The blast destroyed the upper half of the facility, damaged 25 surrounding buildings, and…...
The purpose of this Safety Alert is to highlight the risks associated with compromised pressure relief circuits on Cryogenic Tank Containers. Cryogenic Tank Containers are commonly used for transportation and/or storage of cryogenic liquids, including, but not limited to, Nitrogen, Oxygen, and Argon. A large explosion occurred at a cryogenic gas transport depot in Tamworth,…...
The transfer of hazardous materials from a cargo-tank motor vehicle to fixed-site storage poses a critical vulnerability in chemical handling. While high-speed highway collisions capture more attention, the Pipeline and Hazardous Materials Safety Administration (PHMSA) estimates that roughly 25% to 50% of serious HAZMAT transportation incidents actually occur during loading and unloading operations. These accidents…...
When we introduce a pipe welding machine (such as an orbital welder) into the fabrication process, the focus of the certification fundamentally shifts. Under industry codes such as ASME Section IX, the individual operating the equipment is no longer classified as a “Welder”; they are designated as a “Welding Operator.” Because the machine handles the…...
I am working with a client who is making every effort to comply with the Maximum Allowable Quantity (MAQ) limits for a flammable liquid process area. This process is a PSM-covered process, so I offered up how to work beyond the MAQ of 480 gallons for a fire control area. This compliance option 5001.3 was…...
It is designed to collect and remove condensate while isolating the relief valve from the mechanical stresses of the discharge piping. Here is a breakdown of its primary functions and operational mechanics:… Membership Required You must be a member to access this content.View Membership LevelsAlready a member? Log in here...
I will be fully upfront for those who wish to challenge me on this topic. YES, ASME B31.3 and 31.5 explicitly state that certain records that are required by the standard do NOT have to be “retained”. However, most people who challenge me on this topic fail to see that ittybitty two-letter word “if” in…...
Structural collapse caused the release of around 2,400kg of highly flammable liquid petroleum gas.HSE investigation found that long-standing corrosion of the steel tower was not dealt with.Workers exposed to the risk of serious injury and burns in a major incident. The refinery has been fined £1 million after a major gas leak following an investigation…...
