For chemical burns caused by liquids, which irrigation approach is recommended?

• A. Copious irrigation with water for 15–20 minutes.
• B. Brush off and flush.
• C. Immediate ointment application.
• D. Cover with dry dressing.

Answer: (A)

When chemical burns from liquids occur, the priority is to rapidly dilute and remove the chemical from the skin. Copious irrigation with water for about 15–20 minutes is the best approach because it washes away the agent, reduces ongoing tissue injury, and lowers the chance of systemic absorption. Running water, a shower, or a faucet stream are all suitable, and continue irrigation until no visible chemical remains and the tissue starts to calm.

Rubbing or brushing off a liquid chemical isn’t ideal because it can spread the chemical or push it deeper into tissue, and liquids respond best to thorough rinsing rather than physical brushing. Applying ointment or covering with a dry dressing before or during irrigation can trap the chemical and hinder removal, potentially worsening injury. After irrigation, proceed with further assessment and care as needed.
