Your local poison control 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 national hotline 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.

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.

The person may receive:

• Blood and urine tests.
• 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 (electrocardiogram, or heart tracing).
• Endoscopy -- camera placed down the throat to see burns in the esophagus and the stomach.
• Fluids through a vein (by IV).
• Medicines to treat symptoms.
• Surgery to remove burned skin.
• Washing of the skin (irrigation). This may need to be done every few hours for several days.
