How acid or chemical burns happen

Acid or chemical burns can happen when a harmful acid or chemical gets on your skin, or in your eyes.

Examples of harmful acids and chemicals include:

  • other household cleaning products, such as toilet, oven, and drain cleaners
  • battery acid (a liquid inside some types of batteries)
  • washing detergents
  • ammonia
  • chemicals used in industries such as farming, manufacturing, construction and laboratories

Information

Many products have a label saying if they're harmful and if there's a risk of burns.

Call 999 if:

  • you or someone else has got an acid or chemical on your skin, or in your eyes

  1. Call 999 for medical help.
  2. Wear gloves to protect yourself from the chemical when helping yourself or someone else, if possible.
  3. Carefully remove any clothing that has the chemical on it, if possible.
  4. Carefully brush dry chemicals off the skin.
  5. Put the affected area under cool or lukewarm running water or pour lots of water over it for about 1 hour.

Important

Do not put anything on the burn, such as skin creams or other chemicals.
