Follow Precautions When Handling Anhydrous Ammonia

Anhydrous ammonia, commonly used as nitrogen fertilizer for row-crop production, is effective but must be used with special care because exposure can cause severe chemical burns and other injuries. Most anhydrous ammonia accidents result from improper handling procedures.

To avoid accidents, always follow these safety precautions when handling anhydrous ammonia:

• Wear anhydrous ammonia rated gloves, eye protection, heavy clothing and other needed protection.
• Work upwind of machinery so it's easier to avoid leaks. Pay attention to which way to run if a leak occurs.
• Watch downwind for places people are likely to be.
• Keep children away from the equipment. It's illegal for youth under 16 to handle, transport, transfer or apply anhydrous ammonia.
• Realize the anhydrous ammonia is under pressure and release pressure slowly.
• Always have a safety water tank of at least 5 gallons and check and change it daily so it is suitable to wash off anhydrous ammonia if someone is exposed to it.
• Check hoses, valves and tubes and handle them with care. Replace old, cracked or malfunctioning parts. Avoid kinking hoses, running over them with vehicles or dragging them on the ground. Store hoses inside during the off-season.
• Make periodic inspections of anhydrous ammonia equipment.
• Make sure co-workers know each others' schedules so they can periodically check each other's welfare.

In addition, exercise caution when transporting anhydrous ammonia. Make sure the nurse tank wagons are properly marked and securely attached to the vehicle pulling them. Tow only one tank at a time and leave plenty of travel time.
