Step-by-step explanation:
When it comes to treating burns, the best option is to use cool water. Cool water helps to cool the burn area and can provide immediate relief. It also helps to prevent the burn from getting worse. It's important to avoid using any products that may trap heat in the burn, such as petroleum jelly, as this can make the burn worse.
