Call the local fire department if a major leak occurs. Safety systems review 14. Anhydrous ammonia is a liquid when compressed or cooled. It requires large quantities of water to neutralize its caustic effects on moist areas of the body. Should a mishap occur while transporting anhydrous ammonia, the spill or leak should be approached from upwind whenever possible. Workers in all industries should know that, despite its common usage, ammonia poses health risks and hazards that require proper use of personal protective equipment (PPE) and safe use and handling procedures. Toggle menu for Why take care of health and wellbeing at work? Anhydrous Ammonia is used in both agriculture as a fertilizer and in industrial facilities as a refrigerant for cooling and freezing. One pair of ammonia-impervious, protective gloves, 3. Take hot work permitting precautions whenever hot work will be performed in areas where ammonia is present. While there are many safety and environmental laws on ammonia, in this article, we will focus on OSHA’s Process Safety Management … The clothing should be tightly closed at the cuffs and collar to restrict the entry of anhydrous ammonia. It is a chemical made up of one part nitrogen (N) and three parts hydrogen (H3). When mixed with lubricating oils, its flammable concentration range is increased. Most uncontrolled releases are due to improper procedures, careless or untrained workers, or faulty equipment. Safety chains are required by North Dakota law. The respiratory system essentially may be paralyzed due to the pain. Toggle menu for What are hazardous manual tasks? Clothing should be heavy duty and of a tightly woven fabric. Always use a hitch pin with a safety clip to be sure the nurse tank will not detach from the applicator and the applicator will not detach from the tractor. Most hose failures occur within 12 inches of the hose end due to flexing of the hose while attached to the nurse tank or applicator. You can let us know your thoughts here. Five gallons of fresh, clean water are to be kept in the emergency water reservoir on the nurse tank and accessible from the ground, according to North Dakota Century Code. This valve is on the discharge side of the transfer pump. A powerful fertilizer delivering nitrogen to topsoil, anhydrous ammonia (NH3) is a popular-but-dangerous chemical applied onto farmlands across the US at the beginning of planting season. This manual summarizes the requirements of environmental and safety laws for anhydrous ammonia refrigeration system operators. Anhydrous ammonia attacks any moist part of the body: eyes, ears, nose, throat, bronchia, lungs, any moist skin. Skin is reduced to a sticky, gooey substance as the chemical burn progresses. Always position yourself upwind or across wind from a bleeder valve to be opened. Title Demonstrate knowledge of anhydrous ammonia and safe practices for its use as a refrigerant Level 3 Credits 6 Purpose This unit standard is for people who work with ammonia as a refrigerant within the refrigeration industries. The acute toxicity of ammonia is a major consideration in the safe design and operation of refrigeration systems. Anhydrous ammonia is heavier than air and will settle in the low areas of the surrounding landscape, such as road ditches, sloughs and valleys. Unless an anhydrous ammonia nurse tank or applicator tank is empty, a person in possession of the tank outside of an anhydrous ammonia storage facility must install an approved locking device on the tank if the tank is left unattended overnight. Using Agricultural Anhydrous Ammonia Safely, EC94-738-B, University of Nebraska Cooperative Extension, University of Nebraska. Anhydrous ammonia has a distinct odor, which humans can detect in concentrations as small as 5 parts per million (ppm). Open the applicator flow meter shut-off valve to prevent pressure from building in the applicator flow meter system. 50 feet from any adjoining property or any highway or railroad mainline, 2. More anhydrous ammonia is used as fertilizer in North Dakota than any other nitrogen fertilizer source. Respiratory protection is extremely important, but also limited in what equipment is available. It is accurate only if the tank is level. Refer to Table 6 for a suggested safety checklist. Carry the nurse tank hose by the valve body or coupling rather than by the valve wheel or control handle. Keep the informative decals on the equipment up to date. Safety procedures for working with anhydrous-ammonia (7664417) are presented. The following five personal protective equipment items are required by the North Dakota Anhydrous Ammonia Law to be readily available at the storage site: 1. This valve is on top of the tank (Figure 4) and prevents excessive pressure from building up in the tank caused by overfilling or expansion from heat (Figure 9). Any tissue containing moisture is chemically burned. Everyone who works with anhydrous ammonia should carry a 6- or 8-ounce squeeze bottle of fresh water on their person at all times. Notify the hospital that the victim is being transported. The liquid fill valve (Figure 4) is used while filling the nurse tank from a bulk storage facility. These decisions should be made by emergency personnel, such as a local fire department. It can also cause very severe burns. The chemical burns into the body tissue unless it is diluted by large quantities of water. 5. Anhydrous ammonia may not be transferred from an anhydrous ammonia bulk delivery vehicle to a nurse tank or applicator tank unless the tank is equipped with an approved locking device. Operating procedures 3. Emergency Equipment (for Escape Only). NDCC 28-32-02 Chapter 19-20.2 Anhydrous Ammonia Facilities. review 7. Using Anhydrous Ammonia Safely on the Farm, Minnesota Extension Service, University of Minnesota. The rotary gauge (Figure 10) mounted on the end of an anhydrous ammonia tank, bulk tank, nurse tank or applicator tank consists of a dip tube inside the tank and a bleeder valve. Using Anhydrous Ammonia Safely on the Farm, Educational Package AG-EP-2192, Agricultural Extension Service, University of Minnesota. The nurse tank running gear should be inspected before each use. Management systems 13. Practice Safety when Handling Anhydrous Ammonia (PDF) Anhydrous Ammonia Safety Tips (PDF) First aid can be given while transport arrangements are being made, but get the victim to medical care as soon as possible. 9. Know where these respirators are located and how to use them. Precomm. 6. Apply heat only to open containers, including all piping. Dirty water may not flow through the reservoir hose, preventing treatment of the exposure. 2. Anhydrous ammonia is extremely destructive to animal tissue. Eyes are continually bathed in moisture. Point the bleed hole away from your face and slowly open the bleeder valve. safe procedures and good-quality equipment do work. This gauge is used to determine the actual level of anhydrous ammonia in the tank. At low concentrations, the odor of anhydrous ammonia usually will drive the unprotected worker away from the scene. Inspect the nurse tank wagon frame before each use. The use of a safety clip on the hitch pin when towing anhydrous ammonia nurse tanks on and off the road is essential to your safety and that of the public. Anhydrous ammonia has the potential to be one of the most dangerous chemicals used in agriculture today. During the off-season, the hose should be stored in a vertical position, hanging from the shoulder of a coupling in a cool, dry location. It is especially dangerous to the eyes. Due to the seriousness of exposure to anhydrous ammonia, personal protective equipment must be well-maintained. Anhydrous ammonia causes freezing and chemical burn wherever skin and clothing are moist. Use the in-page search or filters to find what you need. The effects of breathing in anhydrous ammonia range from lung irritation to severe respiratory injuries, with possible fatality at higher concentrations. The need for particular safety equipment and procedures is the same, regardless of the location of the facility.
