CAUTION: In freezing conditions, do not cover the eyewash nozzles until
draining is complete. If you put the covers on prematurely, the covers may
freeze and seal the eyewash heads to create a vacuum. As a result, the water
cannot drain and may freeze inside the eyewash.
3.4 Testing the Shower
To test the shower:
1. Open the shower valve and observe the water spray for the following:
a. Ensure the water is clear.
b. Ensure the pattern of water spray is a minimum 20" (508 mm) diameter
pattern from the shower head and 60" (1524 mm) at standing level. If the test
fails, you may need to remove the shower head to
remove
an obstruction.
2. If applicable, ensure the alarms operate as designed.
3. Stop the water flow and alarms (if applicable) by pushing up on the pull rod to its
original position
4. Inspect the shower activation devices by doing the following:
a. Ensure they are securely fastened to the valve stem of the ball valves.
b. The valves must open and close in one second or less.
