In the decontamination sequence, which step should occur first?

• A. Remove contact lenses
• B. Begin flushing with water
• C. Apply ointment
• D. Wipe with a cloth

Answer: (A)

Removing contact lenses first is best because lenses can trap OC spray against the eye, keeping the irritant in close contact with the cornea and blocking irrigation from effectively rinsing away the chemical. By taking the lenses out at the outset, irrigation water can reach the eye more completely, helping to dilute and remove the irritant.

After lenses are removed, the next essential step is flushing with water or saline to thoroughly rinse the eye for an extended period, typically several minutes, while keeping the eye wide open to allow solution to wash over all surfaces. This sequence minimizes ongoing irritation and reduces the chance of lasting damage.

Wiping with a cloth or applying ointment aren’t the primary actions for immediate decontamination. Wiping can spread residue and irritate the eye, and ointment can create a barrier that traps the chemical or obscures vision, delaying full decontamination. The focus should be on removing the contaminant quickly and rinsing the eye thoroughly, then reassessing and seeking medical evaluation if symptoms persist.
