What hazard class is anhydrous ammonia?

Anhydrous Ammonia: (SDS) Safety Data Sheet

Is anhydrous ammonia considered hazardous material?

Hazard Description Ammonia is an irritant and corrosive to the skin, eyes, respiratory tract and mucous membranes. Exposure to liquid or rapidly expanding gases may cause severe chemical burns and frostbite to the eyes, lungs and skin. Skin and respiratory related diseases could be aggravated by exposure.

How is anhydrous ammonia shipped?

Bulk anhydrous ammonia is typically shipped as a liquefied compressed gas. In the U.S., ammonia is transported in pipelines, pressure tank cars, pressure tank trucks, pressure tanks, and refrigerated barges. For long-distance marine shipping, ammonia is usually carried in mid-size liquefied petroleum gas (LPG) ships.

Do you need Hazmat to haul anhydrous?

For anhydrous ammonia in domestic transportation and described as UN1005 ammonia, anhydrous 2.2 Inhalation Hazard, a Hazardous Materials Safety Permit (HMSP) is not required.

What neutralizes anhydrous ammonia?

Orange juice and other mildly acidic liquids will help neutralize the chemical. Water from a nearby farm pond also can be used until other water supplies are available. Even with proper first aid, seek medical help as soon as possible.

What are the dangers of anhydrous ammonia?

Symptoms can range from mild to moderate – such as vomiting, abdominal pain and burns to the mouth, esophagus and stomach – to severe, including corrosive damage to the mouth, throat and stomach. Inhalation: Inhaling ammonia gas can cause breathing problems, wheezing or chest pain.

How do you neutralize anhydrous ammonia?

This reduces injuries, caused as soon as anhydrous ammonia contacts skin or clothes. If water is not immediately available, use any non-toxic liquid such as cold coffee. Orange juice and other mildly acidic liquids will help neutralize the chemical.

What is the difference between ammonia and anhydrous ammonia?

The term “anhydrous” means “lacking water,” whereas “aqueous” means “dissolved in water.” Anhydrous ammonia (in either the gas or compressed liquid state) may, however, contain a small amount of water. If ammonia is not actually dissolved in water, then the ammonia must be considered anhydrous.

Is ammonia considered hazardous waste?

a HAZARDOUS WASTE. Contact your state Department of Environmental Protection (DEP) or your regional office of the federal Environmental Protection Agency (EPA) for specific recommendations. Prior to working with Ammonia you should be trained on its proper handling and storage.

What happens when you add water to anhydrous ammonia?

When anhydrous ammonia comes in contact with water, it forms an alkali that chemically burns animal tissue. The chemical burns into the body tissue unless it is diluted by large quantities of water.

What is the purpose of anhydrous ammonia?

Anhydrous ammonia is also an important industrial cleaner, where its full strength can eradicate some strains of harmful bacteria and make industrial metal shine. As a fertilizer, anhydrous ammonia gas is compressed into liquid and mixed with other plant growth enhancers.

What does anhydrous ammonia do to the body?

Caustic burns result when the anhydrous ammonia dissolves into body tissue. Most deaths from anhydrous ammonia are caused by severe damage to the throat and lungs from a direct blast to the face. When large amounts are inhaled, the throat swells shut and victims suffocate.

Where are the Placards on anhydrous ammonia tanks?

In general, placards are required on all four sides (i.e. “…on each side and each end…”) of a cargo tank pursuant to §172.504 (a). And, as a bulk packaging, a nurse tank of anhydrous ammonia must display the placard for Division 2.2 Non-Flammable Gas.

Do you need a hazmat label on anhydrous ammonia?

HazMat labels not required on bulk packaging of this type and capacity per §172.400 (a). In general, placards are required on all four sides (i.e. “…on each side and each end…”) of a cargo tank pursuant to §172.504 (a). And, as a bulk packaging, a nurse tank of anhydrous ammonia must display the placard for Division 2.2 Non-Flammable Gas.

Can a nurse tank be used for anhydrous ammonia?

If a nurse tank is used for anhydrous ammonia according to the specified conditions and complies with the requirements of 49 CFR 173.315 (m) (1) (i-vii) listed above, then it is subject to the following exceptions: Shipping papers are not required.

How is anhydrous ammonia transported by the highway?

Be sure to give farmers plenty of room on the road but also take a moment to observe the packaging and hazard communication methods in use when anhydrous ammonia is transported by highway in nurse tanks. Contact me with any questions you may have about the transportation of hazardous materials by air, highway, vessel, or rail
