Chemical burns rinsed with water

  • Flush the area for at least 20 minutes.
    • Do not use a hard spray of water, because
      it can damage the burned area.
    • Have the person with the burn remove
      the chemical substance if he or she is able.

    jewelry that has the chemical on it.

    burning sensation after 20 minutes, flush the area again with flowing water for
    10 to 15 minutes.

    chemical off the skin and then flush with water. If alcohol is not available,
    flush with a large amount of water. Do not flush the eye with

    mild, soapy solution if the burns are not severe. Sulfuric acid feels hot when
    water is added to the acid, but it is better to flush the area and not leave
    the acid on the skin.
  • Dry powders, such as dry lime, are brushed
    away first, because adding water can make a liquid that burns. After the powder
    is brushed away, flush with water for 20 minutes.
  • Metal compounds are covered with mineral
