Measuring range up to: 3 m. Medium: Anhydrous ammonia. A concentration of more than 5,000 ppm will disable a person so that escape is impossible and suffocation results. Another 5 gallons should be maintained on the tractor for use when the nurse tank water may not be easily accessible or runs out. Point the bleed hole away from your face and slowly open the bleeder valve. The valve opens directly to the atmosphere when the tank reaches 250 to 265 psi and closes when the interior pressure drops below 250 psi. Why BEPeterson is a Proud Manufacturer of Northrop Grumman Reservoir Vessels? One cubic foot of anhydrous ammonia in a liquid state produces 855 cubic feet of ammonia gas. The roll cage must be strong enough to prevent damage to the gauges and valves. The victim always should be taken to professional medical help as soon as possible. Repairs can be done only by a repair organization with a valid “VR” certificate of authorization from the National Board of Boiler and Pressure Vessel Inspectors. Temperature/Pressure Relationships 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. At this temperature, ammonia freeze-burns human skin on contact. The fire department has self-contained breathing apparatus (SCBA) and protective suits. Louisiana State University LSU Digital Commons LSU Agricultural Experiment Station Reports LSU AgCenter 1952 Anhydrous ammonia equipment Harold Thomas Barr The emergency water reservoir also must be attached to the nurse tank and be filled with 5 gallons of clean, fresh water. Although the hose is protected by an excess flow valve in the liquid withdrawal valve on the nurse tank, the hose must be in good condition to prevent an uncontrolled release (Table 3, Nurse Tank Hose Safety Checklist). 2. When unplugging metering screens, close the liquid withdrawal valve on the nurse tank and the hose valve on the applicator, open the bleeder valve on the applicator side of the nurse tank withdrawal valve and turn the applicator to bleed the distribution system. One pair of ammonia-impervious, protective gloves, 3. It also is part of the bulk storage facility used to stop the flow of anhydrous ammonia when the operator of the facility detects an emergency situation and decides to stop the transfer of anhydrous ammonia immediately. Make arrangements to transport the victim to a doctor or hospital immediately after exposure. Protective equipment is required by law to be available where anhydrous ammonia is handled or applied.

Additional water should be carried on every tractor used in field applications and in every field support motor vehicle. 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. Anything less will not sufficiently protect a person in this situation. This type of respirator does not have the capacity to protect a person from high-level exposures. 2. Knives in poor condition may result in frequent stops for cleaning and unplugging, increasing exposure to anhydrous ammonia. Inspect the nurse tank wagon frame before each use. Application. The following items are required at anhydrous ammonia bulk storage facilities: 1. Many safety features must be built into the anhydrous ammonia handling and application system. ■ Tow no more than two portable tanks behind one vehicle.■ The speed limit is 25 miles per hour.■ The overall length of the entire transporting unit may not exceed 75 feet.■ Nurse tanks can be transported only on public roads between sunrise and sunset.■ A slow moving vehicle (SMV) emblem or a lighted rotating or flashing amber light must be displayed on the rear of the towed nurse tank.■ Safety chains must be used if nurse tanks are towed faster than 15 miles per hour.■ Tanks must be identified in the front and rear and both sides with the words “ANHYDROUS AMMONIA” in letters not less than 2 inches high.■ Tanks must be placarded in the front and rear and on both sides with approved Department of Transportation (DOT) “NON-FLAMMABLE GAS” placards.■ The DOT “NON-FLAMMABLE GAS” placard (“1005” decals) are also required to be on the nurse tank. The pilot project is coordinated by the North Dakota Insurance Commission, Anhydrous Ammonia Inspection Office, State Capitol, Fifth Floor, 600 East Boulevard Ave., Bismarck, ND 58505-0320. A self-contained breathing apparatus (SCBA), which supplies the air to be breathed, and a sealed, protective HazMat suit are required for working in a cloud of escaping anhydrous ammonia. Safety chains are required by North Dakota law. Use a checklist to keep an accurate inventory when parts need to be replaced. 8. Be sure the couplers are securely reattached. In its diluted form, it is the most widely used compound in households, as well as industrial cleaning applications. At low concentrations, the odor of anhydrous ammonia usually will drive the unprotected worker away from the scene. Do not drape a hose over any edge that allows the hose to become flat. The goggles and gloves are to be kept in a safety equipment container mounted on each nurse tank and be accessible from the ground. Make sure emergency water is available. Generate drawing and 3 D pictures for customer before building the, Finding someone able to work on our “unique” system was proving to be a challenge. Heated nitrogen gas is then fed into the container. On all hose one-half inch outside diameter and larger, used for the transfer of anhydrous ammonia liquid or vapor, there shall be etched, cast,or impressed at 5-foot intervals the following information. Using Anhydrous Ammonia Safely on the Farm, Educational Package AG-EP-2192, Agricultural Extension Service, University of Minnesota. Always make sure that there are no obstructions or blockages around the control wheel and hoses. Due to the seriousness of exposure to anhydrous ammonia, personal protective equipment must be well-maintained. The liquid withdrawal valve (Figure 4) connects the nurse tank hose to the interior of the nurse tank for removal of the ammonia. The results often are disfiguring. The compound also finds its major use in agriculture. Canister type respirators may be effective for longer periods at higher concentrations, but without skin protection, walking through an ammonia cloud is generally not advisable. The North Dakota Legislature adopted the following rules as a pilot project for locking anhydrous ammonia tanks in several North Dakota counties. 9. Replacement dial assemblies also available. This interior pressure is affected by the quantity and temperature of the anhydrous ammonia in the tank. Light weight, thin fabrics will not slow down or prevent anhydrous ammonia from passing through. The roll cage protects gauges and valves if the nurse tank rolls over. Collect as much water as possible and continue flushing while arrangements are being made to transport the victim to a medical facility. This water should be changed daily to keep it clean. We design ammonia tanks for the storage of anhydrous and aqueous ammonia. It is used and stored under high pressures, which requires specially designed and well-maintained equipment. Each tank is in- spected, tested, and stamped by an inspector qualified by the National Board of Boiler and Pressure Vessel Inspectors. Dultmeier Sales will be closed Thursday, November 26th and Friday, November 27th in observance of Thanksgiving . Animals and livestock should be removed from the threatened area after people have been taken care of first. Apply heat only to open containers, including all piping. The entire respiratory system is very moist, so anhydrous ammonia will be attracted naturally to that part of the body. External Visual Inspection Guidelines for Anhydrous Ammonia Nurse Tanks and Applicator Tanks. One cubic foot (28.3 liters) of liquid anhydrous ammonia vaporizes to 855 cubic feet (24,196.5 liters) of gas. The fit should be loose enough for easy removal but snug enough for good protection. 11. First-response rescue workers may not be able to treat a serious inhalation exposure. More anhydrous ammonia is used as fertilizer in North Dakota than any other nitrogen fertilizer source. For example, at 60ø F, the pressure is 93 psi and at 100ø F, the pressure is nearly 200 psi. The pressure gauge (Figure 4) indicates the interior pressure of the nurse tank. The respiratory system essentially may be paralyzed due to the pain. It is highly advisable to use safety gear while handling anhydrous ammonia. As liquid anhydrous ammonia is transferred into the nurse tank, the vapor in the nurse tank is transferred to the bulk storage tank. It must be under pressure to maintain a liquid state. 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. Things You Need to Know About Water Storage Systems for Fire Prevention, 3 Popular Industrial Storage Tanks Discussed, Everything You Should Know About Glycol Storage, Common Types of Industrial Storage Tanks for Corrosive Gases and Liquids, 5 Advantages of Sourcing Glycol Tanks from BEPeterson, Why BEPeterson is the Leading Provider of Ethylene Glycol ASME Tanks, Fire Prevention Storage Tanks and Industry Standards Discussed in Detail. Anhydrous ammonia is basically ammonia without water (an – without, hydrous – water). Although anhydrous ammonia is useful in several applications, it needs to be stored with care. To minimize the gas cloud, water should be sprayed on the point of discharge, not just on the tank. When the exit valve is opened, ammonia leaves the tank through the valve, supply hose, and quick-release coupler, with the pressure dropping along the way due to friction. The caustic nature of anhydrous ammonia causes skin and tissue burns similar to burns from heat. Extra hose lengths can be coiled and securely fastened to the frame to reduce sagging. Their commitment to customer service, detail and, Full Service Metal Fabrication Since 1935, Low Nox Burners for Power & Utility Industry, ASME Pressure Vessel Quick Opening Closures. I would definitely use them, We have worked with BEPeterson on a couple of projects over the past few years. Open-vented shop goggles never should be used. It is stored under pressure to prevent vaporization so a large volume can be available for use. If the additives react with the tank, lading or components, we recommend that they be added in the product manifold system, outside the anhydrous ammonia tank. Research Institution. Welding should be done only by a welding firm with a type “R” certification in compliance with the North Dakota Century Code. The emergency shut-off valve is another valve not found on a nurse or applicator tank (Figure 12). The indicator shows the liquid level in the tank when the bleeder valve is opened and the knob is rotated to the point where liquid spurts from the bleeder valve. Bleeder valves should be opened slowly. Anhydrous ammonia is also a very cold liquid, as it is released from a tank its temperature is -28F, and can cause serious thermal burns very quickly. Between the boiling and critical points, liquid anhydrous ammonia exerts a vapor pressure which increases with rising temperature. boiling point liquid ammonia at atmospheric pressure -28oF (-33.3 oC) The vapour pressure of ammonia is the pressure at which ammonia gas is in thermodynamic equilibrium with its condensed state. Notify the hospital that the victim is being transported. 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. Anhydrous ammonia (NH3) is widely used as a nitrogen fertilizer for crops. Damaged tissue must be removed surgically so that healing can proceed. Ammonia is a gas at atmospheric temperature and pressure. Check the air pressure in the tires each time the nurse tank is used and inspect them for cuts, bruises and tread wear. 3. Anhydrous ammonia is a liquid when compressed or cooled. All low-pressure tubes on the applicator should be of the same length for a uniform delivery to the knives. Anhydrous Ammonia Safety, 1990. The water should be changed at least daily because it can absorb ammonia from the immediate environment. It was not until we discovered BEPeterson. First aid flushing should be continued while in transport. Safe storage of large volumes of ammonia can be accomplished using properly manufactured vessels built to strict code compliance. Wearing protective equipment greatly reduces the chance of injury from an ammonia release. Peterson on the interaction with our production group at Superior Alloy Technology on the recent projects we, HVM is very happy with the product that BEPeterson made for us.

A cartridge-type respirator is not approved for use at a bulk storage facility. 6. Why Glycol Needs to Be Stored In ASME Tanks? Its chemical formula is NH3, which means that it consists of one atom of nitrogen and three atoms of hydrogen per molecule. Transportation of Anhydrous Ammonia at Ambient Temperatures 1. ■ Always have an 8-ounce squirt bottle of water available when working with any anhydrous ammonia equipment.■ Wear gloves and goggles when connecting or disconnecting nurse tanks and applicators.■ Always have a backup set of gloves, goggles, respirator with approved cartridge and 5 gallons of fresh water when applying or transporting anhydrous ammonia nurse tanks.■ Always work upwind of anhydrous ammonia equipment.■ Carry the nurse tank hose by the valve body or coupling rather than by the valve wheel or control handle.■ Clean hose/applicator connectors before connecting them.■ Hand tighten the valve wheel; overtightening can damage the valve or seals.■ Follow the recommended procedure for connecting and disconnecting nurse tanks and applicators. A respirator equipped with anhydrous ammonia cartridges approved by the National Institute for Occupational Safety and Health (NIOSH) is designed only for low-level exposures not to exceed more than 300 ppm. Open the nurse tank liquid withdrawal valve and hose end valve when ready. Feel free to use and share this content, but please do so under the conditions of our. Remember, never weld on a closed container of any kind; all containers must be completely cleaned and vented. The tank should be painted silver or white to reduce temperatures and pressures resulting from solar heating. Five gallons flowing in a pencil-sized stream will last approximately seven minutes. One pair of impervious protective boots, 5. When a concentrated level of anhydrous ammonia is inhaled, it will burn the respiratory system quickly. More information can be obtained by contacting the Anhydrous Ammonia Inspection Office by telephone at (701) 328-0440 or e-mail at insurance@nd.gov. Anhydrous Ammonia Valves (NH3 Valves) including 12 Volt, Ball, Emergency Shut Off, Filler, Withdrawal, Bleeder, Fill & Vapor, Globe & Angle, Internal Tank, Relief Valves & More! Safety features should be checked each time before using the equipment in the field. Similar to propane, anhydrous ammonia boils below room temperature when at atmospheric pressure. 5. 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. At this temperature, ammonia freeze-burns human skin on contact. It requires large quantities of water to neutralize its caustic effects on moist areas of the body. Respiratory protection is extremely important, but also limited in what equipment is available. 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. NDCC 28-32-02 Chapter 19-20.2 Anhydrous Ammonia Facilities. The ammonia trapped under the eyelids must be flushed out with water or it will continue to burn the eye and related tissues. A storage tank is … The breakaway coupler is dated and has a service life of three years. Level measurement and point level detection in the anhydrous ammonia storage tank. The vapor valve has an excess flow valve (which has a five-year replacement requirement). The exact design pressure varies from system to system, but the minimum design pressure, according to ANSI/CGA G-2.1-2014 – Requirements for the Storage and Handling of Anhydrous Ammonia, is 250 psi. The transport tank must have complete, up-to-date certification and labeling. The gauge is accurate only if the tank is level. Ammonia is a chemical compound used as a fertilizer because it is rich in nitrogen. Ammonia is a potentially dangerous chemical requiring either high-pressure storage vessels or low temperature refrigerated vessels. It is in the form of compressed gas or liquid. The container is first inspected thoroughly for leaks. The risk of working with it is high because of its strong affinity for water, caustic nature, high pressure and very low temperature created when pressure is released. The liquid fill valve (Figure 4) is used while filling the nurse tank from a bulk storage facility. Iowa Fertilizer and Chemical Association. A loading platform because climbing or standing on the wheels of nurse tanks is not permitted while filling nurse tanks, 2. The safety relief valve is not adjustable and should be replaced if it is inoperable. 4. Initially, forcing the victim’s eyelids open after the exposure may be necessary. Anhydrous ammonia is a fertilizer commonly used in North Dakota agriculture. Eyes are continually bathed in moisture. Normally, the odor will drive a person away from the area. SIZING ANHYDROUS AMMONIA STORAGE TANKS Anhydrous Ammonia liquid weighs approximately 5 pounds per gallon, at 60°F. Transport tank truck owners must provide written notice to the board of county commissioners of the intention to transfer anhydrous ammonia from any transport tank to nurse tanks in the particular county. 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). 35Piping at pumps and compressors shall be so arranged as to ensure the safe operation of this equipment. Always position yourself upwind or across wind from a bleeder valve to be opened. The chemical burning starts instantly and the injury becomes worse as time passes. Working with their experts on, BEPeterson was very easy to work with in all aspects of the project and provided a great product. Few problems occur when the ammonia is being handled and applied as intended. Retail storage tanks and nurse tanks for anhydrous ammonia are built to withstand internal pressures of at least 250 pounds per square inch (psi). Dultmeier Sales will be closed Thursday, December 24th at 12pm and all day Friday, December 25th. 7. The bolts and nuts that attach the tank to the frame are especially subject to loosening or breaking. The tank must conform to design guidelines provided by the American National Standards Institute (ANSI). Anhydrous ammonia is a clear, colorless gas at standard temperature and pressure conditions and has a very characteristic odor. A spring-loaded valve closes when the coupler separates from the main body to prevent anhydrous ammonia from flowing out of the hose or the applicator. It opens at 365 psi to relieve excess pressure due to liquid expansion. 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. Those who work with anhydrous ammonia must be trained to follow exact procedures in handling it. Wheel chocks of adequate size must be used on the transport tank and the nurse tank before the transfer processes begin. When anhydrous ammonia comes in contact with water, it forms an alkali that chemically burns animal tissue. Plugged knives can trap pressurized ammonia that will be released when the knife is cleared. Rain will absorb the ammonia and remove it from the air. The intake for this valve reaches nearly to the bottom of the tank so that liquid ammonia will be withdrawn until the tank is nearly empty. 6. Clothing actually is frozen to the skin. One pair of nonvented goggles that meet ANSI Z87.1 impact specifications, 4. The caustic burning can be stopped only by dilution with large quantities of water.
