Mineral spirits are liquid chemicals used to thin paint and as a degreaser. Mineral spirits poisoning occurs when someone swallows or breathes in (inhales) the fumes from mineral spirits.
This article is for information only. DO NOT use it to treat or manage an actual poison exposure. If you or someone you are with has an exposure, call your local emergency number (such as 911), or 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.
The poisonous ingredients in mineral spirits are hydrocarbons, which are substances that contain only hydrogen and carbon. Examples are benzene and methane.
These substances may be found in:
- Mineral spirits (Stoddard solvent)
- Some paints
- Some floor and furniture waxes and polishes
- Some dry cleaning fluids
- White spirits
Note: This list may not be all-inclusive.
Mineral spirit poisoning can cause symptoms in many parts of the body.
AIRWAYS AND LUNGS
- Breathing difficulty (from inhalation)
- Throat swelling (may also cause breathing difficulty)
EYES, EARS, NOSE, AND THROAT
- Severe pain in the throat
- Severe pain or burning in the nose, eyes, ears, lips, or tongue
- Vision loss
STOMACH AND INTESTINES
- Abdominal pain -- severe
- Blood stools
- Burns of the esophagus (food pipe)
- Vomiting, possibly bloody
HEART AND BLOOD
- Low blood pressure -- develops rapidly
- Rapid heartbeat
- Burning sensations
- Loss of alertness
- Memory problems
- Numbness in arms and legs
- Necrosis (holes) in the skin or underlying tissues
Seek immediate medical help. DO NOT make a person throw up unless told to do so by poison control or a health care provider.
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 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 person breathed in the poison, immediately move them to fresh air.
Before Calling Emergency
Get the following information:
- Person's age, weight, and condition
- Name of the product (ingredients and strength, if known)
- Time it was swallowed
- Amount swallowed
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
Take the container with you to the hospital, if possible.
The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. The person may receive:
- Breathing support, including a tube through the mouth into the lungs, and a breathing machine (ventilator)
- Bronchoscopy -- camera placed down the throat to see burns in the airways and lungs
- Chest x-ray
- ECG (heart tracing)
- Endoscopy -- camera placed down the throat to see burns in the esophagus and the stomach
- Fluids through a vein (IV)
- Surgical removal of burned skin (skin debridement)
- Washing of the skin (irrigation) -- perhaps every few hours for several days
How well a person does depends on the amount of poison swallowed and how quickly treatment was received. The faster a person gets medical help, the better the chance for recovery.
Swallowing such poisons can have severe effects on many parts of the body. The ultimate outcome depends on the extent of this damage. Damage can continue to occur for several weeks after the poison was swallowed. Death may occur as long as a month after the poison was swallowed.
