When working with liquid or powdered chemicals, always use suitable safety goggles or a face shield. For non-toxic liquid spills, such as soaps or shampoos, rinsing the eye with fresh water is typically all that is required. Splashes from acids or alkali substances, on the other hand, are dangerous and can result in visual loss. Immediately rinse the eye with plenty of cool water to prevent any irritation from drying out too quickly. If you are working with a toxic substance, then seek medical attention immediately. The ocular damage that can be caused by even small amounts of many chemicals is irreversible. The only cure for chemical burns is time; it takes time for the body to eliminate these substances from its system. Therefore, the earlier that you get help after being exposed, the better your chances of survival.
