OSHA considers anhydrous ammonia to be “immediately dangerous to life and health” at a concentration of 300 parts per million (ppm), or 0.03%. Chapter 4: Offsite Consequence Analysis (April 2004) 7. 1. ammonia refrigerant detectors and monitors. Ammonia's odor provides adequate early warning of its … ASHRAE - (Formerly the American Society of Heating, Refrigerating and Air Conditioning Engineers), founded in 1894, is a building technology society with more than 50,000 members worldwide. Anhydrous Ammonia News; Contact Us; Login; Search for: Menu Close. Ammonia refrigeration facilities that handle or store more than 10,000 lbs of anhydrous ammonia onsite are required to comply with OSHA’s Process Safety Management (PSM) standard and EPA’s Risk Management Plan rule. PSM Ammonia Regulation. Reply: You correctly state that your client's facility is covered by the PSM standard (55,000 pounds of ammonia in the facility's ammonia refrigeration process -- anhydrous ammonia is a highly hazardous chemical covered by PSM at a threshold quantity of 10,000 pounds or greater). In pure form, it is known as anhydrous ammonia. Experience process simplicity. The threshold quantity for this rule to apply is 10,000 pounds or 1 ,943 gallons of anhydrous ammonia. In very large cooling systems, like those in food processing facilities, this is a common choice of refrigerant. PROCESS‘ execution of this project helped bring the hot and cold ammonia storage terminals into regulatory compliance and also provided site personnel with several training tools relative to plant operations. Specifically, this PSM standard is applicable to ammonia manufacturers and facilities with large ammonia refrigeration systems; it does not apply to retail facilities. Therefore, it needs to be properly managed. OSHA believes it is important to maintain the mechanical integrity of critical process equipment to ensure it is designed and installed correctly and operates properly. The PSM rule has a limited retail establishment exemption based on federal OSHA’s conclusion that these facilities do not present the … In sum, we’ve highlighted a few important elements from OSHA PSM for industrial ammonia refrigeration systems, but keep in mind that there are 14 elements in total that one should be familiar. Anhydrous Ammonia, 29 CFR 1910.119 Process Safety Management of Highly Hazardous Materials and the current ANSI standard K61.1, Safety Requirements for the Storage and Handling of Anhydrous Ammonia, for additional information. The PSM rule has a limited retail establishment exemption based on federal OSHA's conclusion Our training programs feature a problem-based learning approach that provides a collaborative job-focused experience to accelerate skill development and helps develop a holistic understanding of a ammonia Process Safety Management (ammonia PSM) system. The PSM Standard is not a one-time occurrence; rather, it is a continuous program that should be sustained as long as a facility is operating a covered industrial ammonia refrigeration system. The identification of any previous incident that had a potential for catastrophic consequences in the workplace; Engineering and administrative controls applicable to the hazards and their interrelationships, such as appropriate application of detection methodologies to provide early warning of releases. R-717); these facilities use ASME B31.5 as their piping RAGAGEP. RMP implements Section 112(r) of the 1990 Clean Air Act amendments, and requires facilities that use extremely hazardous substances to develop a Risk Management Plan and revise/resubmit every five years. Other common chemicals in use at ethanol production facilities that may fall under PSM regulations are anhydrous (or aqueous) ammonia, hydrochloric acid, denaturant, and chlorine dioxide.

While there are many elements of the PSM standard (14 in total), we will focus on the ones that are particularly relevant to the hazards associated with industrial ammonia refrigeration systems: An employer must complete a compilation of written process safety information (PSI) before conducting any process hazard analysis (PHA) required by the PSM standard.
