Anhydrous Ammonia Emergency Response

An anhydrous ammonia release is an emergency for everyone nearby, and the right response is to get away and call 911. This guide covers planning in general terms and sends you to official sources for the actual procedures.

What should I do first if there is a release?

Move away from the release and call 911. That is the only emergency instruction this site gives for the event itself. Detailed procedures for rescue, decontamination and first aid belong to trained responders and to official agencies, and they should never be improvised from an article.

Tell the dispatcher your location, that ammonia is involved, and whether anyone is hurt. Stay on the line if they ask you to and follow their directions.

Why not rush in to help someone?

Many people are hurt a second time when a coworker or family member goes in to help without training or equipment. A release can leave the air unsafe in places you cannot see, and good intentions do not protect your lungs or your eyes.

Responders train for this and carry equipment that farm families do not. The most useful thing you can do is get the right people moving quickly and keep others from entering the area.

How can a farm plan ahead?

A plan on paper is far better than a plan in your head. Write down the farm address and the clearest way for responders to find the field or yard, and post it near phones and in the cab of equipment that works with ammonia.

Walk through the plan with everyone who helps at application time. Make sure each person knows who calls 911, where people gather, and that nobody goes back in.

• Post the farm address and directions where everyone can see them.
• Agree on a meeting spot upwind and away from the work area.
• Confirm that cell service works where you will be working, or have another plan.
• Review the plan each season before the work begins.

Should I talk to my local fire department?

Yes. Many volunteer and career departments appreciate hearing where ammonia is stored and used in their area, and they can tell you what they would need from you in an emergency.

Invite them to visit the farm or the dealer site during a quiet time of year. A short conversation on a calm day can save minutes when they are needed.

Where do I find the official emergency guidance?

OSHA, NIOSH and the product safety data sheet describe the hazard and the response expectations for people who work with ammonia. The Red Cross and your local health department can speak to first aid training in your community.

Do not rely on memory or on advice passed along at the co-op. Procedures are updated, and the people who wrote them are the ones to follow.

What about recovery after an incident?

After any exposure, get checked by a medical professional even if you feel better, because effects can appear later. Keep the product label and safety data sheet handy so that medical staff know what they are dealing with.

An incident can be frightening for a whole family. If anyone is struggling afterward, talk to a doctor, a pastor or a counselor. In the US you can also call or text 988 at any time.

Keep this page of your plan in a place that does not depend on power or a phone battery, such as a printed copy in the truck and in the farm office.

How should workers be briefed each season?

A short briefing before the work starts keeps the plan fresh. Cover where the work will happen, how people will reach 911, who stays in charge, and what everyone does if something goes wrong.

Keep the tone calm and practical. The aim is for each person to know their part without having to think about it under stress, and to feel free to speak up if something looks wrong. An ammonia release can affect people beyond the farm. Neighbors, school bus routes and nearby roads may all matter, and your local emergency management office knows how alerts and road closures work in your area.

Ask them what warnings exist and how households are told to respond. Those instructions come from local officials, and they are the ones to follow.

• Name one person who calls 911 and gives the location.
• Confirm everyone can say the farm address from memory.
• Remind workers that stopping the job is always allowed.
