Poison Control, or a local emergency number

The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national 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 U.S. 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.

See National Poison Control center.

What to expect at the emergency room

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

• Fluids by IV
• Medicines to treat symptoms
• Endoscopy -- camera down the throat to see burns in the esophagus and the stomach
• Materials to dissolve the asphalt
• Oxygen
• Breathing tube
• Bronchoscopy -- camera down the throat to see burns in the airways and lungs
• Irrigation (washing of the skin) -- perhaps every few hours for several days
• Skin debridment (surgical removal of burned skin)

Expectations (prognosis)

How well a patient does depends on the amount of poison swallowed and how quickly treatment was received. The faster a patient gets medical help, the better the chance for recovery.

Hot asphalt cools very quickly and is difficult to get off the skin. Serious burns can easily occur from the extreme heat. Construction workers who work with asphalt should wear protective clothing.
