Ammonia poisoning

Ammonia is a strong, colorless gas. If the gas is dissolved in water, it is called liquid ammonia. Poisoning may occur if you breathe in ammonia. Poisoning may also occur if you swallow or touch products that contain very large amounts of ammonia.

WARNING: Never mix ammonia with bleach. This causes the release of toxic chlorine gas, which can be deadly.

Home Care

DO NOT make a person throw up unless told to do so by poison control or a health care professional. Seek immediate medical help.

If the chemical is on the skin or in the eyes, flush with lots of water for at least 15 minutes.

If the chemical was swallowed, immediately give the person water or milk, unless told otherwise by a health care provider. DO NOT give water or milk if the person is having symptoms (such as vomiting, convulsions, or a decreased level of alertness) that make it hard to swallow.

If the poison was inhaled, immediately move the person to fresh air.

Before Calling Emergency

Determine the following information:

• Person's age, weight, and condition
• Name of product (as well as the ingredients and strength, if known)
• Time it was swallowed
• Amount swallowed

Poison Control

Your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This hotline number will let you talk to experts in poisoning. They will give you further instructions.

This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

What to Expect at the Emergency Room

The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Blood and urine tests will be done. The person may receive:

• Airway and breathing support, including oxygen. In extreme cases, a tube may be passed through the mouth into the lungs to prevent aspiration. A breathing machine (ventilator) would then be needed.
• Bronchoscopy, which involves inserting a  camera into the throat, bronchial tubes, and lungs to check for  burns in those tissues.
• Chest x-ray.
• EKG (electrocardiogram, or heart tracing).
• Endoscopy - a camera down the throat to see burns in the esophagus and stomach.
• Fluids through a vein (by IV).
• Medicines to treat symptoms.

Outlook (Prognosis)

Damage is related to the amount and strength (concentration) of the ammonia. Most household cleaners are relatively weak and cause little or mild damage. Industrial strength cleaners can cause severe burns and injury.

Survival past 48 hours most often indicates recovery will occur. Chemical burns that occurred in the eye frequently heal; however, permanent blindness may result.
