Many farmers and applicators will soon apply anhydrous ammonia  prior to planting or side-dress after planting. Even with a rush against time and weather, safety should never be compromised. Accidents involving anhydrous ammonia have proven how dangerous and deadly the chemical can be when not handled properly.

The Minnesota Department of Agriculture (MDA) is providing the following tips to farmers and applicators so they can safely apply anhydrous ammonia.

  • Always wear appropriate goggles and gloves. Never wear contact lenses.
  • Be sure to have a clean, adequate emergency water supply of at least five gallons.
  • Exercise caution when making connections and disconnections as if lines contain anhydrous ammonia.
  • Stand upwind when connecting, disconnecting, bleeding lines or transferring anhydrous ammonia. Also, close, bleed, disconnect, and secure valves and transfer lines when taking breaks or disconnecting lines, and be sure to handle the hose end valve by the valve body.
  • Position equipment away and downwind from homes, people and livestock.

Safety is also key to those maintaining anhydrous ammonia equipment. Never assume  lines are empty, always wear proper protective equipment and have access to safety water.

  • When towing a nurse tank down the road, drive sensibly. Do not go any faster than 30 miles per hour, display a slow-moving vehicle (emblem visible from the rear and be sure the tank is secured to the tractor or truck with two separate, independent chains that supplement the hitch pin/clip.
