PHMSA is issuing an Advisory Bulletin to alert all pipeline operators of a T.D. Williamson, Inc. (TDW) Leak Repair Clamp (LRC) recall issued by TDW on June 17, 2013. The recall covers all TDW LRCs of any pressure class and any size. The LRCs may develop a dangerous leak due to a defective seal. Hazardous […]
In the world of process safety and piping design, Hydrostatic Relief Valves (HRVs)—often simply called thermal relief valves—are the unsung heroes that prevent piping ruptures during periods of inactivity. While a standard Safety Relief Valve (SRV) protects against massive surges or process upsets, the HRV is specifically designed to handle the thermal expansion of trapped
Over the last several years we have come across several facilities that handle anhydrous ammonia and have a dangerous misunderstanding of “hazardous locations”. It seems that somewhere/someone had informed them that their engine room(s) did not need proper ventilation since they were below the 10,000 pound PSM/RMP threshold. They were badly misinformed and here’s why…
The U.S. Department of Transportation’s Federal Railroad Administration (FRA) has issued an Emergency Order and Safety Advisory to help prevent trains operating on mainline tracks or sidings from moving unintentionally. The FRA’s announcement was made in response to the July 6, 2013 derailment in Lac-Mégantic, Quebec, Canada, as it awaits additional data once the investigation
This Coffee Break Training continues the second part of administrative tips on how to read and apply the model codes.
PHMSA is issuing this safety alert to notify the public of the risks associated with the under-odorization of Liquefied Petroleum Gases (LPG). LPG is an odorless and colorless gas that under certain conditions is required to be odorized for leak detection. The purpose of this alert is to advise shippers and carriers of the recommended
PHMSA is issuing an Advisory Bulletin to remind owners and operators of liquefied petroleum gas (LPG) and utility liquefied petroleum gas (utility LP-Gas) plants that although they must follow the American National Standards Institute/National Fire Protection Association (ANSI/NFPA) standards 58 or 59, they must also follow certain sections and requirements of Part 192.

The CSB has made the following OBSERVATIONS and PRELIMINARY findings to date, which are subject to further revision and development as the investigation unfolds:
The IRSST just published a method of measuring nanoparticles penetration through protective gloves. With the exponential growth in industrial applications of nanotechnologies and the corresponding increased risk of occupational exposure to nanomaterials, adoption of the precautionary principle is advisable. To apply this principle, personal protective equipment against nanoparticles must be made available, even though it
The IRSST just published a guide for safe use of isocyanates. The guide is intended for anyone working in the field of occupational health and safety. It is designed to educate, inform and raise awareness, and has no regulatory value. Readers will come to understand the chemical hazards associated with isocyanates and will be able
