Caution urged when dealing with anhydrous

Safety is also key to those maintaining anhydrous ammonia equipment


ST. PAUL — Recent accidents involving anhydrous ammonia have proven how dangerous and deadly the chemical can be when not handled properly.

The Minnesota Department of Agriculture (MDA) provides the following tips for safely applying 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 5 gallons.

  • Use caution when making connections and disconnections.

  • Stand upwind when connecting, disconnecting, bleeding lines or transferring NH3. Also, close, bleed, disconnect and secure valves and transfer lines when taking breaks or disconnecting lines, and be sure to handle hose end valves 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 NH3 lines are empty, always wear proper protective equipment and have access to safety water.
When towing a nurse tank, drive no 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.

If an accident or spill occurs, immediately call 911 and then the Minnesota Duty Officer at 1-800-422-0798 or 651-649-5451.
