Which step is explicitly advised for chemical burns in basic first aid?

• A. Wash with large amounts of water, remove contaminated clothing, cover area loosely with clean soft cover, do not apply ointment, grease, powder or other agents
• B. Rub the burnt area with ice
• C. Apply butter or oil on the burn
• D. Break blisters to release fluid

Answer: (A)

Chemical burns need immediate removal of the irritant and protection of the injured tissue. Washing with large amounts of running water helps dilute and rinse away the chemical, reducing ongoing damage. Removing contaminated clothing stops further exposure to the chemical on the skin. Covering the burn loosely with a clean soft dressing protects it from infection and contamination without trapping the chemical. Avoid putting anything on the burn—no ointments, grease, grease, powders, or other agents—because these can react with the chemical, worsen the burn, or hinder healing. The other steps are not advised: ice can cause more tissue injury, butter or oil can trap the chemical, and breaking blisters increases infection risk and delays healing.
