EPA EHS (Extremely Hazardous Substance):

Despite the common odor, anhydrous ammonia properties are dramatically different from those of household ammonia cleaning solutions (dilute ammonium hydroxide, NH4OH). An uncontrolled release of NH3 can easily be fatal or cause permanent disabling injury.

If you are new to NH3 operations, study everything you can about this chemical and how to use it safely.

Missing Manual Hazard

The nurse tank(s) you own or are leasing may not have current manuals. If so, the nurse tank topics in this manual need your attention. These pages cannot be a substitute for a complete and current nurse tank cart manual, but they cover important information for using nurse tanks safely.

Suffocation, Blinding, Burning, Freezing, Disabling and Disﬁgurement Hazards:

Your life and health, the lives and health of your workers and community, the continued commercial availability of anhydrous ammonia, and continuation of agricultural NH3 transport exceptions depend on you conducting meticulously careful operations.

Be Aware of Signal Words

Signal words designate a degree or level of hazard seriousness.

DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. This signal word is limited to the most extreme situations, typically for machine components that, for functional purposes, cannot be guarded.

WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury, and includes hazards that are exposed when guards are removed. It may also be used to alert against unsafe practices.

CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.

Deﬁnitions

The following additional terms are used throughout this manual.

NOTICE indicates a crucial point of information related to the preceding topic. Read and follow the directions to remain safe, avoid serious damage to equipment and

ensure desired field results.

Note: Useful information related to the preceding topic.

Right-hand and left-hand as used in this manual are determined by facing the direction the machine will travel while in use unless otherwise stated. An orientation rose in some line art illustrations shows the directions of: Up, Back, Left, Down, Front, Right.

A consistent system of callouts is used for most implement and nurse tank cart components. See page 42 for an applicator system illustration.

Prepare for Emergencies

▲ Keep emergency numbers for doctor, ambulance, hospital

and ﬁre department near phone. Know the reporting requirement for spills or releases of the chemicals you are using. Have contact numbers available.

▲ For anhydrous ammonia operations, have additional

contact information for:

• national response center

• regional (state) response center

• local response center

▲ Have a ﬁrst aid kit for typical farm injuries, but ignore it for

anhydrous ammonia exposure. The only ﬁrst aid for anhydrous ammonia is water.

Fertilizer Type: 82-0-0 Chemical formula: NH CAS number: 7664-41-7 EC NUMBER (EINECS): 231-635-3 EC INDEX NUMBER: 007-001-00-5

NH3 is a colorless gas at room temperature (any clouds observed in releases are usually water or ice condensed from the air by the refrigerant effect of NH3 evaporation).

NH3 is a colorless liquid, and is only a liquid at room temperature if chilled and/or under pressure.

NH3 gas has a distinctive odor that provides warning of dangerous concentrations (unless you have impaired sense of smell, or develop olfactory fatigue/adaptation due to extended low-level exposure).

Safe ﬁeld operations can keep exposures below permissible limits. Unsafe operations, accidents and malfunctions can result in exposures at ANY concentration.

Why Anhydrous Ammonia (NH3) Differs…

…from typical liquid fertilizers:

▲ NH3 is intensely hygroscopic:

On contact with water, such as unprotected skin, eyes, mouth, airway and lungs, it dissolves immediately, desiccating the cells and forming ammonium hydroxide.

▲ NH3 is highly caustic:

Ammonium hydroxide formed on contact is a strongly corrosive alkaline solution, resulting in severe chemical burning of skin and mucous membranes.

▲ NH3 is volatile:

NH3boils at -28 °F (-33.4 °C), expanding by over 850 times. It remains liquid in the nurse tank only because it is pressurized at up to 250 psi. Leaks or above-ground releases immediately cause an expanding gas cloud. Tanks begin venting above 116 °F (46.7 °C).

▲ NH3 has a high heat of vaporization:

NH3is a powerful refrigerant. Evaporating (boiling) liquid NH3may be at -100 °F (-73 °C), freezing whatever water it touches (in addition to the other hazards). This can freeze clothing to skin, prolonging tissue damage.

▲ NH3 is combustible:

Although NH3generally does not burn with a self-sustaining ﬂame in the ﬁeld, it is a signiﬁcant ﬁre hazard in closed areas and/or if released near hot ignition sources (such as during welding on implements).

▲ NH3 is reactive:

Although the reactivity is classiﬁed as “0” (in the NFPA 3-1-0 diamond for emergency response purposes), NH3does react with various materials, and can produce hazardous byproducts and/or have hazardous side-effects.

NH3 is corrosive to a surprising number of metals (see page 35). Repairs with incompatible parts are likely to result in malfunctions and a serious accident. Brass parts in particular can fail rapidly, from the inside out.

Mixing NH3with some common household and agricultural chemicals can, for example, produce highly toxic gas. Never mix NH3 with acids.

▲ NH3 is attractive to criminals:

Do not leave a loaded tank unattended. Secure your tank. Clandestine lab operators steal NH3from unattended nurse tanks. Criminals and vandals often leave a tank in an unsafe state.

Personal Safety with Ammonia

▲ Carry personal ﬂush water and wear Personal Protective

Equipment (PPE) at all times when working with or near the nurse tank, and when working with an applicator not known to be completely purged. Minimum PPE is:

• Carry a sealed squeeze container with 8-10 ﬂuid ounces (270 ml) of clean water or saline solution.

• Wear non-vented chemical splash goggles speciﬁed for use with anhydrous ammonia. If you wear glasses, make sure the goggles seal completely. A vented full face mask provides extra splash protection, but is not a substitute for primary non-vented eye protection.

• Wear long cuff chemical gloves speciﬁed for use with anhydrous ammonia. Turn back the cuff ends to catch any liquids when arms are raised.

• Wear clothing made of heavy, tightly woven fabric, that can be closed at the neck, and at the cuffs of long shirt sleeves and long pants. Wear boots or high, closed shoes.

• Have a mirror for inspecting ends of ﬁttings, ports and hoses. Never point an NH3 source at your face.

• Great Plains strongly recommends carrying a wireless telephone or 2-way radio.

▲ Do not wear contact lenses when working with/near

anhydrous ammonia, nor with equipment that may contain residual NH damage faster than you can remove contacts for eye washing.

▲ Unfrozen wash water is required. Completely replace water

daily or more often in the 5 gallon (19 liter) tanks on nurse tank cart and on implement. Wash water tanks may be vented to allow the water out at the tap. The vent allows NH3 gas to enter and gradually form an ammonia solution.

▲ Respirator?

Full face piece respirator protection is required for workers at ﬁxed ammonia facilities, but not for ﬁeld operations. Should you choose to use a full face respirator when operating the applicator, be aware of two risk factors:

1. Loss of Warning: Filter cartridges may reduce

ammonia odor, preventing detection of malfunctions or dangerous fume concentrations.

2. Over-Conﬁdence: Typical respirators are intended

for extended low-level exposure, or escape from high levels. They do not provide extended protection at or above IDLHa (300 ppm).

Ammonia Emergency Action

▲ Have a plan. Execute the plan.

Expect the possibility of exposure or uncontrolled release in any phase of setup, transport or operations. Have contact information at hand. Know the wind direction at all times.

▲ Act Quickly:

Training matters. You must know what to do, and act without hesitation.

▲ Move or Turn Up-Wind:

The ﬁrst priority is to avoid exposure, or stop further exposure. On splash or spill, get out of the vapor cloud. Move up-wind.

If a leak is detected while operating in the ﬁeld, turn the tractor into the wind, lower the implement into the ground and perform an emergency ﬂow shut-off. Pull the rope.

If a breakaway occurred, move the tractor some distance upwind from the disconnected nurse tank.

▲ Apply First Aid:

Treat exposures with water ﬂushing (and only water or saline solution, unless instructed otherwise by a physician). Irrigate continuously. Get professional medical help as soon as possible.

Do not stop with one ﬂush. Apply water until a physician takes over or instructs otherwise. In particular, do not use lotions, ointments, salves or creams. They can trap the harmful agents under the skin.

▲ Close Valves Only if Not in Vapor Cloud

Once clear of the cloud, evaluate if it is safe to close any shut-off valves not already closed. DO NOT re-enter vapor cloud. DO NOT attempt leak/spill control other than valve closure. If Raven SCS 450 console is on, set MASTER switch off. Do not turn POWER switch off.

▲ Escape:

Continue moving upwind of any uncontrolled release. The wind may shift. On a calm day the ammonia cloud expands in all directions.

▲ Notify:

Summon any aid required. Notify local authorities of any uncontrolled release. Protect the public. Protect livestock if that can be done without further exposure.

▲ Stay in Contact:

Be available to responders with whatever information they require. Do not attempt to correct the accident problem yourself. Standard ﬁeld PPEa safety equipment is suitable only for normal operations and escape. Field PPEa is not safe for emergency response.

Ammonia Nurse Tanks

Use nurse tanks with proper current safety certiﬁcation, and current safety equipment and features.

Consult with your anhydrous ammonia supplier for safety information and correct safe handling, transport and use of anhydrous ammonia.

Consult with local and regional authorities on Safe and legal use of anhydrous ammonia, including emergency and environmental contacts, and release reporting requirements.

Review any decals and manuals available for your nurse tank cart, and for any of its components. There may be separate manuals for the tank, running gear, indicators, valves and ﬁttings.

This manual covers typical operations for a representative NH3 nurse tank cart. Compare the features and controls of your cart to the model cart, so that there will be no confusion about instruction steps.

Figure 1

Typical NH3 Terminal

31558

Control Variation Hazard:

If you are using multiple nurse tanks, study each one separately. Unless they are owned by you, and known to be identical, there is a high probability that there are differences between them, even if they are all from the same terminal.

Trailing Nurse Tanks Only:

This manual, and the applicator Operator manual, do not cover operations with “applicator” anhydrous tanks.

A consistent system of callouts is used for most nurse tank cart components.

A51 A51 A87

3-character callouts in the range to refer to nurse tank cart components, decribed on page 10 through page 22.

Nurse Tank Security

Standard Tank Controls:

This manual, and the applicator Operator manual, assume standard (unlocked) tank ﬁttings and controls are in use.

Missing Information Hazard:

Take action to inform yourself. The majority of anhydrous ammonia nurse tanks do not have an operator manual, for the complete cart or for just the tank. Any manual that is available may not accurately document the cart at hand, due to expired component replacement, and/or complete tank replacement.

Field Operations Only:

This manual, and the applicator Operator manual, cover only nurse tank ﬁeld operations. Nurse tank terminal operations, transport, storage and detailed maintenance are beyond the scope of this manual.

Nurse Tank Safety

Many nurse tanks in use today were originally assembled by cart integrators who are no longer in that business, or assembled by an implement dealer, or by an end user.

Cart running gear often remains in service for decades, with a periodic tank replacement, at which time it is essentially a completely different nurse tank cart.

Hoses and various ﬁttings are limited-life components that are routinely replaced, and the replacements may not precisely match the original parts.

In as few as four years, any original cart documentation may no longer accurately describe the cart in its current conﬁguration.

If you do not have a current, up-to-date operator manual for the nurse tank cart, study the “Ammonia Nurse

Tanks” section of this manual, starting on page 8.

Example:

Peeling and

Missing

Safety and

Informational

Decals

Missing Information Hazard:

Many nurse tanks have no operator manual. They may not have even a tank operator manual. If there is a manual, the cart may have been modiﬁed, or the tank replaced. Fittings are routinely replaced. Study how the nurse tank works. The tank conﬁguration, ﬁtting, hoses, indicators and controls may vary from the original documentation (if any), and vary from the typical tank described in the section “Ammonia Nurse Tanks” on page 8.

▲ Do not ﬁll, accept or use a tank unless it conforms to

current regulatory and safety requirements, and passes a careful inspection. Print pages 23 and 24 to use as checklists. If the answer to any of the items is “no”, do not use the tank.

▲ Pull-type two-axle tanks only

(no semi-mounted nurse tank carts).

▲ Maximum total capacity 3000 gallons.

▲ Never ﬁll to more than 85% capacity.

▲ Never transport a nurse tank behind an implement on

public roads.

▲ Never park a tank on public roads or in populated areas.

▲ Transport slowly: 20 mph (32 kph) maximum

▲ Never leave a loaded NH3 tank unattended.

Never leave a nurse tank unsecured.

▲ Know and follow the law applicable to anhydrous ammonia

tanks, transfer, transport and application. Some jurisdictions require permits and speciﬁc documents and equipment conﬁguration for highway transport.

▲ Know how to perform a basic safety inspection of a nurse

tank (page 23). Do not ﬁll or accept or ﬁll a tank that fails inspection.

Nurse Tank Cart Components

For use with a Nutri-Pro®applicator, the nurse tank must be a full-trailering pull-type with two or more axle running gear. The Nutri-Pro mounted tank.

Note: Callout numbers A51 through A87 identify the

same nurse tank components throughout this manual and the applicator Operator manual.

Cart Hitch

Refer to Figure 2

A51 A Nutri-Pro®applicator requires a nurse tank with a

clevis hitch having a locking 1 inch (2.5 cm) pin. See the applicator Operator manual for cart hitching and page 31 for unhitching.

A52 At least one safety chain is required. In some

regions, regulations may already require two safety chains. Each chain, clasp, and weld must be rated for the gross weight of the loaded cart.

A53 The tongue may have supports or caddies for hose

management (the depicted cart has the Acme parking plug on top). Make sure you understand the purpose of any tongue features.

When the nurse tank hose is attached, check that the forward point at which it is secured to the tongue or cart frame is at least 3 feet (92 cm) from the implement break-away, with enough slack to elevate the hose at least 13 inches (33 cm) above the implement breakaway.

Note: Nutri-Pro

harness at the rear hitch, as ﬁeld operations do not require nurse tank lights. If the nurse tank has lights, make sure there is provision to secure that harness during ﬁeld operations.

Note: A Nutri-Pro®implement does not provide pass-

through connections for air, hydraulic or electric brakes, as ﬁeld operations do not require brakes. If the nurse tank has brakes (rare), make sure they can be set to off (freewheeling), and there is provision to secure the unconnected brake lines during ﬁeld operations.

A54 Nurse tank cart tongues typically have unlimited

vertical movement. If the tongue pivots have stops, make sure the clevis can be elevated to at least 48 inches (122 cm) above ground (for implement lift in ﬁeld turns).

Nurse Tank Front End

A cart may have one or two tanks. A two-tank cart often has a separate hookup for each tank. A two-tank, twohose cart may be used with a dual-cooler implement, or a single-meter implement (one tank after another).

Refer to Figure 3

See page 4. This information is for trained users of the material and emergency responders.

A56 25 MPH mirror image decal:

This decal is for the beneﬁt of the operator transporting the cart on public roads. It reads legibly in a rear view mirror.

A57 Acmea parking plug:

An acceptable nurse tank must have a means of securing the outlet end of each hose. This is usually an Acme-threaded plug mounted on the tank or tongue. See the applicator Operator manual for hose hookup and unhitching.

A58

A56

A55

Figure 3

Nurse Tank Front

A59

31559

Vapor Exposure Hazard:

Acme plugs typically do not have gaskets, and do not make a gas-tight seal. Residual liquid or gas in the hose slowly vents at the plug. Use valves to close lines.

Refer to Figure 4

A58 Acme Female Hose Coupler:

On a leased tank, the terminal may supply no hose, in which case you need to provide your own.

This end of the hose connects the tank withdrawal valve to the leading implement inlet at the breakaway coupler. For use with a Nutri-Pro applicator, the outlet end of the hose must be equipped with a 13⁄4-4 female Acme ﬁtting.

The outlet end of the hose has a swivel collarb or shroud containing the female Acme ﬁtting. This allows connection without needing to twist the hose.

Acme hose couplers are intended for hand tightening only. Do not use tools to make the cartimplement connection. A liquid-tight seal is made by the gasket in the male Acme ﬁtting on the implement break-away coupler.

A58

Figure 4

Acme Hose Coupler

Suffocation, Blinding and Burning Hazards:

Never disconnect at an Acme coupler without ﬁrst:

• shutting off the line at all valves, and

• bleeding the line at the connection. Be up-wind for all operations.
