Here's a checklist to keep you on track:
Proper Protective Clothing and Safety Equipment
The right gear is the first line of defense when working with NH3:
- Long-sleeved shirts and pants: Always wear full clothing to minimize exposed skin.
- NH3-rated goggles: Use tight-fitting, chemical-rated goggles. Never wear contact lenses.
- Chemical gloves: Wear gloves that are rated for chemical protection and make sure they’re cuffed at the wrist to prevent splashes.
- Safety Data Sheet (SDS): Always refer to the manufacturer’s SDS for additional safety requirements and recommendations.
Proper Emergency Water Supply
Quick access to water can be lifesaving in case of exposure:
- 5-gallon emergency water supply: Keep at least one for every nurse tank.
- Additional emergency supply: Always have a backup water supply in your truck or tractor.
- Personal eyewash bottle: Carry an eyewash bottle for immediate access to rinse your eyes in case of exposure.
Water is your primary defense in an emergency, and it must be clean and easily accessible. Ensure that emergency water supplies are available even when performing equipment maintenance.
First Aid and Emergency Treatment
If there’s an emergency, acting fast is essential:
- In case of ingestion or eye exposure: Call 911 immediately. DO NOT induce vomiting if NH3 is ingested. Drink plenty of water to dilute the chemical.
- Frostbite or burns: Liquid ammonia can cause severe burns and frostbite. If skin contact occurs, flush the area with water for at least 15 minutes. If clothing is frozen to the skin, do not remove it.
- Frostbite or severe skin injury: Never try to treat this yourself—get medical help right away.
Proper Handling and Placement of Equipment
Safe handling of NH3 is just as important as having the right equipment:
- Stand upwind: Always position yourself upwind and avoid standing in the line of fire when connecting or disconnecting lines, transferring NH3, or bleeding lines.
- Check hoses and lines: Inspect hoses for cracks, cuts, or bulges. Never assume equipment is empty, and always check for leaks.
- Proper valve management: Always close, bleed, disconnect, and secure valves when equipment is unattended. When operating valves, use the body, not the latch or wheel, and open valves slowly.
- Proper parking: Never park nurse tanks or equipment in built-up areas or near residences, schools, or hospitals.
Proper Care When Transporting NH3
When transporting NH3, always adhere to safety regulations:
- Speed limits: Follow local speed limits and regulations, usually a maximum of 25 mph when towing nurse tanks.
- Valves and couplers: Ensure all valves are fully closed during transport, and make sure couplers/breakaways are fully articulated.
- Crossing railroad tracks: Stop completely before crossing railroad tracks if no gate is present.
- Placards and signage: Ensure your ammonia tank is properly labeled and placarded. Display a slow-moving vehicle (SMV) emblem and use two independent safety chains.
In the Event of a Release
If an NH3 release occurs, follow these steps:
- Move upwind immediately to avoid exposure to the harmful gas.
- Call 911 and inform them that NH3 is being released.
- Do not attempt to stop the release unless you are properly equipped and trained.
- Eliminate nearby ignition sources to prevent fire hazards.
By following these guidelines, you can significantly reduce the risk of accidents and ensure the safe handling of NH3. Safety is a shared responsibility in the fertilizer industry. Let’s stay vigilant, prepared, and safe, so we can continue to protect workers, growers, fertilizer facilities, and our communities.
