First, the quantity in the mixture does not count if the partial vapor pressure of the HHC is less than 10 mm Hg. What is this information? Operating procedures 4. In recent years, OSHA has stepped up adherence to this standard via rigorous inspections enforced by its National Emphasis Program (NEP) on Process Safety Management regulatedindustries which include the eco-friendly ammonia refrigeration facilities. For anhydrous ammonia (R-717), the most commonly used industrial refrigerant, the threshold value is 10,000 pounds, and a PSM program as defined by OSHA Standard 29CFR 1910.119 is required. Give us a call to discuss your training needs. OSHA also lists threshold quantities for other highly hazardous chemicals that are covered under the PSM regulation. chemicals stored at their facilities in excess of the PSM Threshold Quantities (PSM-TQ) and employers that are operating facilities that fall within known NAICS codes that commonly have chemicals stored at their facilities in excess of the PSM-TQ. McNeil’s PSM experts have worked in ammonia refrigeration facilities across the United States and will help you design and implement a complete PSM program. General Duty vs. PSM/RMP: Is there a benefit to dropping below the 10,000lb threshold? Home. Contractors These lists, though not representative or inclusive for each country and state, are a good basis for understanding what programs a facility should have to operate safely and yet comply with outside agencies or local chapters with jurisdictions over their facility. The regulations apply to stationary sources that have a listed chemical in a process at or above an established threshold quantity. Our average of twenty two years of experience in ammonia PSM provides our customers with the knowledge and understanding to mitigate regulatory liabilities. OSHA Process Safety Management (PSM) Standard List . When the system design requires more than 10,000 pounds of ammonia charge, both OSHA and the EPA get interested. (NOTE: This is commonly referred to as “Recognized and Generally Accepted Good Engineering Practice” – RAGAGEP. In order to arrange for training classes in any country, it is advisable that a “train-the-trainer” approach is followed where employers arrange for training of their senior staff to coordinatewith relevant inspection companies in the US. Home; About; Blog Subscriptions ← How should I FIX a PSM program? Ten percent by weight of 1,000 pounds is 100 pounds of diborane. The Hazard Assessment must identify potential public and environmental receptors that may be affected in the event of an accidental release. ), Compiling and updating the following information are essential to GDC compliance:• Process Safety Information (PSI) including current P&ID’s(NOTE: A crucial standard to be considered is in IIAR Bulletin 110 -Section 4: Records). Only the contained amount of the HHC counts toward the TQ, not the entire quantity of the mixture. News and Discussion Blog on Process Safety Management for Ammonia Refrigeration. Clarifying the PSM exemption for atmospheric storage tanks; 2. Among others, PSM applies to facilities with over 10,000 pounds of anhydrous ammonia contained in a refrigeration system. Aqueous ammonia is also a regulated substance in the RMP regulation, but only when in concentrations greater than 20%. Ammonia refrigeration systems that have 10,000 pounds of ammonia (approximately 2,000 gallons) or more are subject to OSHA’s process safety management requirements. The U.S. Occupational Safety and Health Administration (OSHA) established the PSM standard to keep employees safe from highly hazardous chemicals, and facilities with an ammonia threshold of more than 10,000 lb must comply by developing and implementing a PSM plan. For … For example, the threshold quantity for hydrogen sulfide under PSM is 1500 pounds, whereas under RMP, the threshold is 10,000 pounds. (While this is the rule that most companies follow, there is some confusion in the wording which suggests that any release meeting or exceeding the RQ must be reported immediately.) Prerequisite: NONE “Implementing Process Safety Management for Ammonia Refrigeration Systems” 6th Edition. We provide professional ammonia PSM consulting. All of this material is covered or introduced to the student at our seminar. Several times a year I get a phone call or an email from a client that wants to lower the NH3 inventory below the federal 10,000lb threshold so they are no longer subject to the PSM/RMP rules. 134 and ANSI: Z9.2 for … High Liner Foods has a level of ammonia that is over the 10,000 pound threshold quantity. 13. AutoPSM is ammonia PSM software that helps achieve refrigeration safety with process simplicity. IF THE FACILITY HAS LESS THAN 10,000 lbs – (LIGHTER CHARGE OF AMMONIA)When a facility has less than 10,000 pounds of ammonia charge in its refrigerating system, both OSHA’s PSM and EPA’s RMP use their respective General Duty Clause (GDC) and RAGAGEP getsinvolved to inspect and generate citations .
