Chemical Injuries: First Aid
Revised: August 16, 2023
Published: December 31, 1994

Chemical injuries to tissue are caused by contact with harmful chemicals such as lye, acids, and strong cleaning supplies.  Also called chemical burns, they can be similar to thermal (heat) burns and treatment can be complex and last many weeks. Prompt removal of the chemical agent and rapid veterinary medical attention can help minimize the injury and speed healing.

What to Do

  • Seek veterinary care immediately.
  • Avoid being bitten by using a muzzle on your pet if you think there is a risk of being bitten.
  • Wash the contaminated area with large volumes of tepid (lukewarm), flowing water for at least 15 minutes.  
  • In the case of dry chemicals, brush them away carefully, taking care to protect the eyes, nose, and mouth of both you and your pet.
  • If the chemical is in the eye, flush the eye with large volumes of water or contact lens saline for 15 minutes. (See below for the saline recipe.)  
  • Make sure the area is well-ventilated as some chemicals can release strong fumes.

What NOT to Do

  • Do not apply neutralizing agents to the skin or eyes. They can cause a chemical reaction that produces heat and cause further injury to tissues.  
  • Do not immerse your pet in non-flowing water if a dry chemical has spilled on him or her. These dry chemicals are usually activated by water. The water must be flowing in order to rinse the chemical away.

Pure water can be quite irritating to the eyes and raw skin. It is much more comfortable for your pet if you use saline: simply dissolve 2 teaspoons of table salt in one quart of water (metric: 9 grams of salt in 1 liter of water).
