On July 13, 2012, EPA modified the EPCRA Section 312 Emergency and Hazardous Chemical Inventory Forms (Tier I and Tier II) to add new mandatory and optional data elements under the facility identification and contact information sections of both forms. EPA also revised some existing data elements on the chemical reporting section of the forms […]
Cylinder Colors While the cylinder label is the primary means of identifying the properties of the gas in a cylinder, the colour coding of the cylinder itself, can often time provide a further guide. Cylinder Shoulder – European Standard Color CodingThe color applied to the shoulder, or curved part, at the top of the cylinder,
For nearly 16 years I have seen clips of a “dashcam” video that claims an NH3 transportation accident (w/ nurse tank) claimed the life of an IL State Trooper. The video is on dozens of websites and we even see it used in training courses and almost always the video is depicted as being real
FRA is issuing Safety Advisory 2012–01 to remind shippers and consignees of railroad tank cars containing odorized liquefied petroleum gas (LPG), of the importance of taking actions to ensure that a sufficient level of odorant remains in the LPG throughout the entire transportation cycle. FRA is issuing this notice to raise awareness within the hazardous materials community,
The NIOSH Respirator Selection Logic (RSL) relies entirely on whether the airborne concentration of a contaminant exceeds a defined exposure limit (such as the NIOSH Recommended Exposure Limit [REL] or OSHA Permissible Exposure Limit [PEL]), regardless of what the chemical’s vapor pressure is. However, vapor pressure plays a decisive role in selecting a respirator, particularly
I am sure many of you have heard the old saying… “it’s just common sense” when it comes to applying PTFE (Polytetrafluoroethylene) tape, often called “thread sealants” or “plumber’s tape”. Yet this practice is a critical skill for ensuring leak-free connections in threaded piping systems. While it seems straightforward, the direction and tension of the
On the ASME Form U-1 (Manufacturer’s Data Report for Pressure Vessels), the information regarding Postweld Heat Treatment (PWHT) is typically found in Line 14.
An ASME B31.3 welding quality assurance (QA) program must cover the full lifecycle of a weldment, from procedure qualification to final testing, to ensure structural integrity. It serves as a mandatory framework for contractors to demonstrate that their processes and personnel consistently meet the minimum safety requirements for process piping. The QA program must include the following:
With all the changes to Ammonia Refrigeration RAGAGEPs, many businesses forget that the IFC and their state fire code no longer cover refrigeration; they gave all that to IIAR. But since the IFC no longer covers refrigeration, how does NH3 get covered under the IFC? Is it flammable, toxic, or corrosive?
In ASME B31.3, the number of welds that require visual inspection depends entirely on the Fluid Service Category designated for the piping system. Because visual inspection is the primary quality control method, the requirements are strict. For the vast majority of process piping (Normal Fluid Service), 100% of the completed welds must be visually inspected.
This traffic camera footage of a Bromine Release in Russia is some of the most amazing HAZMAT footage I have ever seen. The officials at the time and when I reported it in the Incident Alerts stated it was a “small release from a pail”. Now with this footage available, we can clearly see this
