What action should NOT be taken when treating a chemical burn?

Applying ointment is not a recommended action when treating a chemical burn because it can trap the chemical agent against the skin, potentially exacerbating the injury and hindering the cleansing process. Immediate and thorough irrigation of the burn with water is critical to dilute and remove the chemical substance, which helps to minimize tissue damage and promote healing.

Additionally, removing contaminated clothing is important to prevent further exposure to the chemical. Covering the affected area loosely with a clean dressing or cloth can also protect it from infection and further injury while allowing for continued inspection and treatment. Therefore, avoiding the application of ointment is crucial in the initial management of chemical burns.
