What is first aid for someone getting chlorine gas in their eyes?

1. Bandage tightly with gauze

2. Slather with vaseline

3. Flush with cold water for 15 minutes

4. Flush with sodium dioxide solution to neutralize the chlorine

The correct answer is: Flush with cold water for 15 minutes

Flushing the eyes with cold water for 15 minutes is the standard first aid treatment for exposure to chlorine gas. Chlorine can cause severe irritation or burns to the eye tissues, and prompt action is necessary to minimize damage. By flushing the eyes, you help to remove the chlorine and dilute any remaining chemical present, which can significantly alleviate discomfort and potential injury. The procedure of using copious amounts of water is critical because it not only aids in physically removing the irritant but also helps to calm the affected area. It is important for the individual to keep their eyes open while being flushed to ensure thorough cleansing and to continue the flushing for the recommended duration. This action can greatly reduce the risk of long-term damage to the eyes. Alternatives like bandaging or applying substances such as vaseline are not appropriate actions for chemical exposure as they can trap the harmful agent against the skin or eyes, worsening the situation. Neutralizing agents, like sodium dioxide, may not be effective or safe for treating eye exposure and could potentially lead to further complications. Thus, the most effective and accepted method for treating chlorine gas exposure in the eyes remains flushing with clean cold water.
