Final answer:
In the case of a chemical eye injury, the victim's eyes should be flushed with lukewarm water. Hot or cold water can worsen the injury, and chemical disinfectants are not suitable for use on the eyes.
Step-by-step explanation:
In the case of a chemical eye injury, it is recommended to flush the victim's eyeball(s) with lukewarm water. Using water that is too hot or too cold can cause additional damage or discomfort. Lukewarm water is the most suitable for flushing out chemicals because it helps to wash away contaminants without causing thermal shock to the eye tissues.
When handling beakers of hot water or any hot fluids, always exercise caution to avoid burns. Similarly, care should be taken with chemical disinfectants; while they are effective for killing microorganisms on surfaces, they are not suitable for use in treating chemical eye injuries due to their potential to cause further harm.
It is important to note that substances like hydrogen peroxide are irritants, and chemicals like hydrochloric acid are corrosive, both of which can cause serious eye damage. Therefore, prompt and appropriate first aid action is critical in mitigating the harm from chemical exposures.
