What is the first action to take if your eyes become contaminated with a nerve agent?

The appropriate first action to take if your eyes become contaminated with a nerve agent is to flush your eyes with uncontaminated water. This step is critical because immediate decontamination can help minimize the absorption of the toxic substance and reduce the risk of severe effects. Flushing the eyes helps to wash away the chemical agent and can mitigate damage.

Using a nerve agent antidote is beneficial but should come after decontamination, as the antidote works more effectively when the body is free from the contaminant. Donning a protective mask is essential in situations where airborne agents are involved, but it doesn't address eye contamination directly. Reporting to the nearest medical facility is necessary for further treatment, but it should follow the immediate action of flushing the eyes to ensure the best possible outcome.
