Anhydrous Ammonia Inspection

Anhydrous Ammonia (NH3) is a pressurized gas, used as an agricultural fertilizer. NH3 tanks are inspected for compliance with safety requirements. If improperly handled or stored, NH3 can be dangerous.

Necessary documentation for the inspection:

  • Equipment list, tank identity
  • Storage facility registration
  • Any other supporting information, repairs problems, etc.

What to expect during an inspection:

Anhydrous Ammonia Site should be registered for the current year. Tanks should be inspected annually and written documentation of the inspection should be given to the site owner. An inspection sheet can be downloaded at the link below. Inspectors will be looking for the following.
