You may have seen this latest and greatest “detection method” in your junk mail, pop-up ads, or in a search of the internet. These tapes work and they work well in my experiences, but as with any product, there are some serious drawbacks that one must understand before using these products. Before I get into…...
Many of you that handle anhydrous ammonia are familiar with The Compressed Gas Association’s (CGA) 2.1, Requirements for the Storage and Handling of Anhydrous Ammonia, which is the baseline RAGAGEP for ammonia fertilizer distributor facilities. But the organization has another ammonia standard, G-2, Ammonia that is an EXCELLENT compliment to CGA 2.1. The G-2 standard…...
I have written many articles on “scrubbing NH3” in preparation for line breaks/equipment openings or emergency removal from a compromised container and with NH3 the scrubbing media is simply water (H2O). I learned these “scrubbing” methods while working one summer in an internship and the safety pro who hired me was also an MSU graduate…...
Chlorine (Cl2) has a strong warning property: most people can detect Cl2 at approximately 0.002 ppm in air (the official odor threshold per the Agency for Toxic Substances and Disease Registry) and 0.31 ppm in water. However, most data indicate an odor threshold of 0.2-0.4 ppm. In other words, even the most minute leak will…...
This is a common question we get regarding pressure testing and leak testing of process piping. I have written quite a few posts regarding the ASME B31.3 and 31.5 requirements for pressure and leak testing over the years, but this question about holding pressure for 24-hours is one that just will not die. I am…...
Most of my clients who are users of Chlorine (Cl2) use it in vacuum systems where the Cl2 is being injected or inducted into a water flow. In these smaller “processes” it is not unusual to find “tubing” being used vs. hard pipe. It took me years to accept the tubing design model as I…...
I have asked for an official interpretation on this question, but until that arrives I will answer this question as I did for a client this week. Here is the scenario: There is a significant fire in the RMP covered. The fire does NOT cause a release of the EHS, much less get off-site. However,…...
The Chlorine Institute has updated its instruction booklet for applying an A Kit to 100-LB. & 150-LB. Chlorine Cylinders. Remember, these Instruction Booklets can be downloaded for FREE from their bookstore and if your facility is using 100 or 150 pound Cl2 cylinders, the A Kit is a MUST HAVE and training on the proper…...
Technical Safety BC (British Columbia) has issued two new safety orders regarding ammonia in refrigeration plants. Failure to comply with the requirements of these safety orders may result in enforcement action under the Safety Standards Act and associated regulations. These two (2) safety orders are: Safety Order SO-BP-2021-01: Secondary Coolant Safety Order SO-BP-2021-02: Emergency Discharge…...
Back in February of this year, I posted an article on how badly broken our “Industrial Zoning” process is broken in the USA. The article was titled: “FAILURES of true “facility siting” – our “zoning” process is broken and dangerous!” and it was about a chemical plant’s pleas to the city council to not rezone…...
The number 1 failure that causes releases of anhydrous ammonia in agricultural and bulk transports is hose failures! Without a doubt, at a fertilizer distribution center, loading and unloading DOT containers via transfer hoses pose the greatest risk for a catastrophic event. So special attention is deserving when it comes to the hose(s) we will…...
NOTE: Anyone can download these pamphlets for FREE; just visit the CI bookstore and go through the purchasing process as if you were buying them and you will NOT be charged or even asked for a credit card! The Chlorine Institute (CI) has updated their Pamphlet 95, Gaskets for Chlorine Service (Ed. 6), and added…...
