This kit includes the eyewash bottle, the holder and a 500ml bottle of isotonic water.
When you accidentally get chemicals in your eyes, seconds count. The sooner the eye is thoroughly flushed, the better the chances of minimizing any damage to your eyes and eyesight.
That's why, even if a sink is available, it's ideal to have this small shower and isotonic solution available to neutralize the PH of the foreign chemical.
This plastic container has a base to cradle the eye(s). It avoid struggling over a sink as you just have to fill the bottle with the solution and press on the lever to use.
