What initial action should be taken for a chemical burn?

Rinsing the area with copious amounts of water is the appropriate initial action for a chemical burn because it helps to dilute and wash away the chemical substance that caused the burn. This is crucial as many chemicals can continue to cause damage as long as they are in contact with the skin. The goal is to remove any residual chemical agents and reduce the extent of the burn injury.

In contrast, applying ointment may trap the chemical against the skin and facilitate further tissue damage, while covering the burn with a cloth without rinsing could also cause more harm by maintaining contact with the irritant. Seeking immediate medical attention without rinsing is generally not advisable for chemical burns, as immediate decontamination with water can prevent further injury and is a priority before medical assessment.
