In a scenario involving a chemical splash to the eye, what is the first action the dispatcher should instruct the caller to perform?

• A. Blink rapidly to remove chemical
• B. Rinse the eye with clean water for 10-15 minutes
• C. Apply ointment
• D. Cover both eyes with a dry cloth

Answer: (B)

Immediate irrigation with clean running water is the first action to take when a chemical splashes the eye. The purpose is to rapidly dilute and flush out the chemical to minimize tissue damage, since eye tissues can be harmed quickly by many chemicals. Instruct the caller to start rinsing the affected eye right away with clean water (or sterile saline) and continue for about 10 to 15 minutes, keeping the eyelids held open so water flows over the surface. If safe to do so, remove contact lenses to improve flushing, but avoid forcing them out if it causes delay or pain. Do not rub the eye, apply ointment, or cover the eye with a dry cloth, as these actions can worsen injury or trap residual chemical. If possible, continue irrigation during transport and relay any known chemical involved to medical personnel.
