How should a flight attendant administer first aid for a chemical burn?

Rinsing the affected area with copious amounts of water is the most effective first aid response for a chemical burn. This action helps to dilute and remove the chemical substance causing the burn, minimizing further skin damage and alleviating pain. It's crucial to flush the area thoroughly for at least 15 minutes, as this can significantly reduce the impact of the chemical on the skin and surrounding tissues.

Applying ointment or covering the burn with a dry cloth is not advisable immediately, as these actions can trap the chemical against the skin or cause further irritation. Waiting for medical personnel to arrive without taking action can lead to increased harm, as immediate washing with water is critical in managing chemical burns effectively. Thus, rinsing the burn with water is the best practice in this scenario.
