What is an important first step in treating chemical burns?

The first step in treating chemical burns, especially those involving dry chemicals, is to brush off the dry substances from the skin. This is critical because leaving the chemical on the skin can lead to continued damage and worsening of the burn. Many chemicals can react further with moisture or other substances, increasing the severity of the injury. By carefully removing the chemical, the risk of additional harm is minimized.

Other options may seem like they could provide relief or protection, but they can exacerbate the situation. Applying ice can lead to further tissue damage, as cold can constrict blood vessels and hinder healing. Covering the burn with ointment immediately can trap the chemical against the skin, causing prolonged exposure to the harmful agent. Wrapping the area in a dry cloth might also create a similar problem, as it can hold the chemical against the skin.

Therefore, brushing off dry chemicals is the most appropriate and effective first step in managing chemical burns, ensuring that further damage is prevented.
