Because the loading risers were not equipped with excess flow valves to limit the uncontrolled release of anhydrous ammonia, approximately four (4) tons of anhydrous ammonia were released. Spill containment pans will be provided at the point of loading operations and is an essential piece of equipment in overall site safety and environmental protection. A wider access gangway (36″- 48″ is preferable) as it helps improve access and egress to and from the vessel. Determine if the loading station or other anhydrous ammonia system is covered by the PSM standard. A smaller diameter pipe will provide more resistance to the flow, potentially reducing the flow rate below the actuation rate of the valve. SafeRack’s professional technical sales consultants are available to meet with your team to make recommendations to keep your facility in front of OSHA’s ever-changing country and region-specific standards and regulations, including. Figure 3 shows a breakaway device that may be used in place of the protection offered by the bulkhead and location cable.

In addition to the requirements identified by OSHA in 29 CFR 1910.111 and 29 CFR 1910.119, the ANSI K61.1 standard and the recently revised North Dakota Anhydrous Ammonia regulation identify additional steps that employers can take to provide protection during hose severance and vehicle pull- away. Skin Protection: Wear chemical protective clothing e.g. If the flow in the pipe exceeds a predetermined level, the valve is triggered and will automatically close. In the United States, ammonia is typically a “tight-fill” (closed-loop) loading operation and is loaded into trucks or rail cars via chemical hoses, by-pass arms or stainless steel arms. The piping, valve arrangement, and program logic are based on the stringent safety standards used in the chlorine industry for the unloading of railcars (The Chlorine Institute Pamphlet 57). [, Develop and implement an emergency action plan for the facility and include procedures for handling small releases. Guidance for Implementation of the General Duty Clause: Clean Air Act Section 112(r). The product was delivered fast.

In addition, a wider gangway will reduce the risk of the operator’s PPE getting caught, torn or damaged, and will improve productivity and safety. In addition, pursuant to Section 5(a)(1), the General Duty Clause of the Act, employers must provide their employees with a workplace free from recognized hazards likely to cause death or serious physical harm. Treating straw with anhydrous ammonia has many advantages, such as high efficiency, low cost, simplicity of operation and elimination of parasite eggs and weed seeds. Eyewash stations need to be on the same horizontal plane with no obstructions. Recent fatalities during releases at anhydrous ammonia loading stations illustrate the potential hazards associated with transfer operations if the transfer system is not adequately protected from hose severance or an inadvertent pull-away during transfer. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) 3 These Regulations apply to stationary bulk storage facilities for anhydrous ammonia … www.OSHA.gov, Occupational Safety and Health Administration [, Check and inspect to assure that the equipment in the process, including the transfer station, are installed properly and consistent with design specifications and the manufacturer's recommendations. When anhydrous ammonia is released from compression in a storage tank (200 psi) to the atmosphere (0 psi), the temperature drops from 100 F to minus 28 F.
