How should chemical burns to the skin be treated?

The proper treatment for chemical burns to the skin involves thorough flushing with water to remove the chemical irritant and minimize damage to the tissue. Flushing the burn area for a minimum of 20 minutes is critical, as this duration helps to adequately dilute and wash away the chemical substance that caused the burn. Immediate and extended exposure to running water can significantly reduce the reaction time of the chemicals and limit the depth and severity of the burn.

The choice of flushing for 20 minutes aligns with guidelines emphasized by burn management protocols and organizations focusing on emergency care. Ensuring a long enough duration of irrigation is essential since some chemicals can continue to cause harm as long as they remain in contact with the skin.

A shorter flushing duration, like 10 minutes or less, may not be sufficient to ensure that the chemical is fully removed, potentially leading to further injury. Covering the area with a sterile bandage without proper flushing first would not adequately address the underlying concern of the chemical remaining in contact with the skin. Additionally, applying ointment immediately could trap the chemical against the skin and exacerbate the burn, delaying proper care.
