Caution with caustics: Tips for preventing chemical burns

Test Image

The bottom line

Caustic products cause burns on contact with skin, eyes, and the gastrointestinal tract. More than other household products, caustic substances do their damage instantly. Injury cannot be reversed, only treated.

Prevention Tips

  • Purchase a caustic product only if nothing else will do the job.

  • Store products in their original containers with the child-resistant cap on tightly.

  • NEVER transfer these products into food or beverage containers.

  • Read the label carefully and follow directions exactly.

This Really Happened

A 75-year-old woman swallowed a liquid drain opener which had been transferred to a water bottle. Two days later she went to the emergency room complaining of chest pain, throat pain, and trouble swallowing. A CT scan of her chest revealed inflammation of her esophagus (food tube). A gastroenterologist performed an endoscopy (a lighted tube is inserted into the body) of her esophagus, stomach and the upper part of her small intestine, three days after she ingested the drain cleaner. The endoscopy revealed a burn in her esophagus.

The patient was placed on an intravenous drug to decrease stomach secretions and a liquid diet excluding any acidic substances. She was released from the hospital four days after the ingestion. During a follow-up call from the poison center to the home two-and-a-half-weeks after the patient drank the drain opener, her daughter reported that she was eating more solid food and was doing well.

The full story

Chemical burns are one of the most devastating injuries that can happen at home. Recently, a young child drank from a container of cleaning fluid that his dad brought home from work. The liquid burned his mouth and throat, then burned all the way down to his stomach. He survived, but with serious injuries. He will need surgery many times over the next several years.

Such dangerous chemicals are also found at home. "Caustics" are very strong acids (pH ≤2) or very strong alkaline products (pH ≥12). They can be liquids or powders or granules. Chemical burns occur instantly if these products touch your mouth, eyes, or skin.

This photo above on the left is from a household drain cleaner. Most people know that this type of product is dangerous. Other products at home that can cause chemical burns include oven cleaner, rust remover, toilet bowl cleaner, dishwasher detergents, some laundry pod detergents, some swimming pool chemicals, and cleaning products for brick and concrete.

Protect yourself, your family members, and your pets from chemical burns. More than other household products, these substances do their damage instantly. Injury cannot be reversed, only treated.

  • Purchase a caustic product only if nothing else will do the job.

  • Buy only the amount that you need. Store it safely, locked out of sight and reach of children and pets.

  • Store products in their original containers with the child-resistant cap on tightly.

  • NEVER transfer these products into food or beverage containers.

  • Read the label carefully and follow directions exactly.

  • Wear gloves, protect your skin, and open the windows if the label says to do so.

  • Do NOT use these products when children or pets are around.

Here are first aid tips for working with products that can cause chemical burns.

  • If it splashes into your eyes, IMMEDIATELY rinse with running water for at least 20 minutes. Then use the webPOISONCONTROL® online tool for guidance or call your poison center at 1-800-222-1222.

  • If it splashes onto your skin, IMMEDIATELY rinse with running water for at least 20 minutes. Take off any clothing with the product on it while you're rinsing. Then use the webPOISONCONTROL® online tool for guidance or call your poison center at 1-800-222-1222.

  • If you breathe in the fumes, get into fresh air IMMEDIATELY. Then use the webPOISONCONTROL® online tool for guidance or call your poison center at 1-800-222-1222.

    The castor bean is the seed of the castor oil plant (Ricinus communis). It contains a highly toxic compound called ricin, which is released when the seed is crushed or chewed. Ricin prevents cells from making proteins, which are essential to life. Although castor oil is made from the same seeds, it does not contain ricin.

    What happens if a skunk sprays me?

    Skunks spray to repel potential predators with a foul-smelling, oily secretion stored in their perianal glands. For humans, it usually does not result in much more than short-term irritation. In dogs, in addition to irritation it can rarely cause a more serious condition in which the red blood cells are destroyed. Leaving skunks (as well as all wildlife) alone and making your home less attractive and inaccessible to them are the keys to prevention.
