Spring is in the air! And farmers are in the fields! This time of year brings with it an uptick in operators hauling anhydrous ammonia. Please give operators space and grace as they move slowly and safely on the roads, especially turning into field sites.
🚜 The rules for transporting anhydrous ammonia in North Dakota include:
· The driver must be at least 18 years old
· Operators towing nurse tanks can never exceed 25 mph
· Haulers are required to have a Slow Moving Vehicle (SMV) sign or use flashing amber lights while in transport
· Tanks must be identified on the front, rear, and both sides with the words 'Anhydrous Ammonia' and 'Inhalation Hazard'
· Tanks must be identified on the rear and both sides with the words 'Non-Flammable Gas' and the number '1005'
· Up to two nurse tanks can be hauled by a single vehicle
· Overall length cannot exceed 75 feet
· Travel only between sunrise and sunset, unless transporting a single tank and equipped with taillights, turn signals, and brake lights
✋ Stay safe before you leave:
· Secure the Load. Always use two independent safety chains in addition to a locking hitch pin with a retainer clip.
· Before hitting the road, shut off all valves and disconnect transfer hoses. Never transport a "charged" system on public roadways.
· Conduct a full walk-around. Check tires for proper inflation and weathering, and inspect the wagon frame for cracks or wear.
· Protective gloves and Z87 rated goggles must be in a safety kit attached to the container or the frame of the wagon.
👀 Anhydrous is the Greek word for “without water.” Because it contains no water, Anhydrous ammonia has a very strong affinity for water. Anhydrous ammonia attacks any moist part of the body: eyes, ears, nose, throat, bronchi, lungs and any moist skin. Any tissue containing moisture is chemically burned. It requires large quantities of water to neutralize its caustic effects on moist areas of the body. First aid calls for water, water, water.
· Emergency Water: Every nurse tank must carry at least 5 gallons of fresh, clean water. This is your first line of defense for flushing eyes or skin in case of accidental exposure.
· Proper PPE: Even during transport, have your NH3-rated goggles and gloves accessible. Remember: never wear contact lenses when working around ammonia, as they can trap gas against the eye.
