A lot of clients want to know what the minimum flow rates for an Emergency Eyewash
unit and where the specification comes from.
Therefore below is excerpt from the relevant section from AS4775:
AS4775 Emergency eye wash and shower equipment
Section: 7 Plumbed and Self Contained Eye Wash Equipment
7.1 Performance of plumbed and self-contained eye wash units
A means shall be provided to ensure that a controlled flow of flushing fluid is provided to both eyes simultaneously at a velocity low enough to be non-injurious to the user.
When activated plumbed and self-contained eye wash equipment shall deliver flushing fluid to the eyes at a flow rate not less than 1.5 L/min for a minimum of 15 minutes.
I hope this helps with your site risk analysis or providing an accurate response to your boss.
