Eye wash bottles can be found at all laboratory sinks. The eye wash is a disposable bottle with a sterile sodium chloride solution 0.9 %. Due to risks of bacterial growth in a broken bottle it must be disposed even though you havenot emptied it. You can get a new bottle at the health and safety representative, and the one having used the eye wash is responsible for replacing it with a new one.
If you get acids or bases in the eyes you must wash with plenty of the 0.9 % sodium chloride solution. Acid burns create a scab that will protect the tissue so the burn will not be deep. It is more critical with base burns. A base burn does not create scabs, instead it creates water-soluble products, which makes the burn continue and go deeper in to the tissue. If you do not continue the rinsing for a very long time, you risk damaging the cornea.
