Final answer:
If a chemical gets into your eyes, immediately flush with water for 15-20 minutes and seek medical help, not keeping them closed.
Step-by-step explanation:
The proper procedure if a chemical gets into your eyes is to immediately flush the eyes with water for at least 15-20 minutes, and then seek medical attention. Keeping the eyes closed and not rinsing could result in more damage or irritation. Chemicals such as irritants, for example, hydrogen peroxide, can cause significant damage to both the skin and eyes. It's important to act quickly to dilute and remove the chemical from the eye to minimize injury.
