It is found in some soldering fluxes. It may also be found in other products.

Initial symptoms of hydrochloric acid poisoning may include pain in the mouth and under the breastbone, or persistent drooling. Hoarseness and stridor (harsh sound in breathing caused by air passing through constricted air passages) may indicate injury to the larynx, epiglottis, or throat.

• Severe pain in the mouth
• Fever
• Difficulty with or inability to breathe due to swelling of the throat

Seek emergency medical care immediately if you have been exposed to hydrochloric acid and have symptoms (mentioned above).

DO NOT make a person throw up (vomit).

If the acid is on the skin or in the eyes, flush with lots of water for at least 15 minutes.

If the acid was swallowed, give lots of water or milk IMMEDIATELY. If the person is vomiting, keep giving water or milk. Give 4 to 6 oz of milk of magnesia if available.

For inhalation poisoning, move the person to an area with fresh air.

Determine the following information:

• The patient's age, weight, and condition
• The name of the product (ingredients and strengths if known)
• When it was swallowed or inhaled
• How much was swallowed or inhaled

For any ingestion or exposure, seek emergency medical care immediately.

If you suspect possible poisoning, call 1-800-222-1222 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 any containers with you to the emergency room, if possible.

Some or all of the following procedures may be performed:

For swallowed poison:

The prognosis (probable outcome) depends on the amount and method of acid exposure. Extensive damage to the mouth, throat, and stomach are possible. The ultimate outcome depends on the extent of this damage. Drinking or inhaling hydrochloric acid may be fatal.
