What is the significance of rinsing a chemical burn with water for at least 20 minutes?

Rinsing a chemical burn with water for at least 20 minutes is critical because it helps to dilute and remove the chemical substance that caused the burn from the skin. This process is essential in stopping the ongoing damage that the chemical can inflict on the tissue. Many chemicals can continue to reactive with skin or underlying tissues, causing further injury if not effectively removed. Flushing the area with a copious amount of water serves to dilute the concentration of the chemical and wash away as much as possible, mitigating the extent of the burn and reducing the risk of complications. Immediate thorough rinsing can significantly influence the healing process and may even help prevent more severe injuries.
