Anhydrous Ammonia: Storage and Safety

NH3 Fertilizer

As we’ve learned, Anhydrous Ammonia is a potentially dangerous form of ammonia that is extremely useful as an agricultural fertilizer as well as being a resourceful tool in other industries.  Due to its toxic composition, Anhydrous Ammonia needs to be stored, handled and transported in a specific and cautious fashion.

Here are the recommended methods for dealing with this powerful substance.


  1. Contain Anhydrous Ammonia in a pressurized NH3 tank.  Allow extra space in the tank for vaporization to take place without cracking the tank walls. 
  2. Utilize non-corrosive tanks only.  Anhydrous Ammonia will erode certain metals like zinc and copper.  Conduct regular inspections of all tank apparatuses and ensure there are no faulty spots.
  3. Make sure NH3 tanks and all storage containers are white to reflect the sun and the heat.  Also, label the nurse tanks “Anhydrous Ammonia” so passersby are aware of the proximity to the substance.
  4. Comply with all personal protection gear and safety equipment.  Leaks may occur and having the proper gear handy can save your life.


  1. Handling and transferring Anhydrous Ammonia should be well thought out.  Take the time to make sure there are no blockages or obstructions around the hoses and control wheel.  Park your nurse tank right next to the source tank to decrease potential spills and ensure both tanks are stable for the transfer. 
  2. Keep fresh water handy.  Many places make this a requirement in case of contact with the ammonia. 
  3. Make sure you and all other workers are up to date on safety protocols and how to proper use safety equipment. 


  1. As mentioned above, always label tanks properly.  Then securely attach the nurse tank to the towing vehicle.  Prior to any haul, all pertinent parts of the tank and truck need to be inspected, including tires, safety chains and hoses.
  2. Take your time towing Anhydrous Ammonia.  If fact, your vehicle should be marked at “slow-moving” due to the contents of your cargo.  Your speed should not advance past 25mph or 40km/h.  Safety first!
