Propane poisoning

Propane is a colorless and odorless flammable gas that can turn into liquid under very cold temperatures.

This article discusses the harmful effects from breathing in or swallowing propane. Breathing in or swallowing propane can be harmful. Propane takes the place of oxygen in the lungs. This makes breathing difficult or impossible.

This article is for information only and not for use in the treatment or management of an actual poison exposure. If you have an exposure, you should call your local emergency number (such as 911) or 1-800-222-1222 for a local poison control center.


Symptoms depend on the type of contact, but may include:

Touching propane results in frostbite-like symptoms.

Home Care

Seek immediate medical help. If the person breathed in the poison, immediately move him or her to fresh air. If the person does not improve rapidly after moving to fresh air, call your local emergency number (such as 911).

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 instructed 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.

DO NOT make a person throw up unless told to do so by Poison Control or a health care professional.

Before Calling Emergency

The following information is helpful for emergency assistance:

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

However, DO NOT delay calling for help if this information is not immediately available.

Poison Control

In the United States, call 1-800-222-1222 to speak with a local poison control center. 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. You can call 24 hours a day, 7 days a week.

What to Expect at the Emergency Room

The health care provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. The person may receive:

  • Airway support, including oxygen, breathing tube through the mouth (intubation), and breathing machine (ventilator)
  • Blood and urine tests
  • Chest x-ray
  • EKG (electrocardiogram, or heart tracing)
  • Fluids through a vein (intravenous or IV)
  • Medicines to treat symptoms

Outlook (Prognosis)

How well a person does depends on the type of contact with the poison, and how quickly treatment was received. The faster a person gets medical help, the better.

Those with short exposures may have temporary headaches or other mild nervous system symptoms. Stroke, coma, or death may occur with long-term exposure.
