Home Care
Get medical help right away. 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 poison control or a provider. DO NOT give water or milk if the person is unconscious (has a decreased level of alertness).
If the person breathed in the poison, immediately move them to fresh air.

Outlook (Prognosis)
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 this type of poison can affect many parts of the body. Burns in the airway or gastrointestinal tract can lead to tissue death. Infection, shock, and death can follow, even several months after the poison has been swallowed. Scars may form in these tissues leading to long-term problems with breathing, swallowing and digestion.
If gasoline gets into the lungs (aspiration), serious and possibly permanent lung damage can occur.
The harsh taste of gasoline makes it unlikely that large quantities will be swallowed. However, several cases of poisoning have occurred in people trying to suck (siphon) gas from an automobile tank using a garden hose or other tube. This practice is extremely dangerous and is not advised.
