Safeopedia explains Eye Wash
The American National Standard Institute (ANSI) provides standards and regulations for the nature of eye-wash, as well as its placement in a workplace, maintenance and proper use. ANSI requires that the first response for chemical eye injury or particles trapped in the eye is flushing with water. According to ANSI's standard this may be potable water, preserved water, saline solution or any other medically accepted solution. Local laws may apply to some ingredients. Most eye wash kits consist of purified or preserved water or saline solution and some include pain relief or alcohol to aid in cleansing and removing harmful substances.
