How should responders deal with chemical exposure to skin or eyes?

Immediate rinsing or flushing with water is the correct response to chemical exposure to skin or eyes because it is critical to dilute and remove the harmful substance as quickly as possible. For skin exposure, copious amounts of water should be used to wash away any residue, minimizing the chemical's penetration and potential damage. Similarly, for eye exposure, flushing with running water can help to wash the chemical away from sensitive ocular tissues, providing relief from irritation and preventing further injury.

Time is of the essence in these situations; delaying action, as suggested by another option, allows the chemical to cause more harm. The application of ointments may further irritate the affected area or react adversely with the chemical. Covering the area with a bandage before proper rinsing can trap the chemical against the skin and exacerbate the injury. Thus, immediate rinsing or flushing with water is the most effective and recommended first response to chemical exposure.
