CAUTION: Ensure the eyewash ball valve is completely closed. If it is allowed to
drip, it may freeze.
3.3 Testing the Eyewash
To test the eyewash:
1. Actuate the eyewash and check the eyewash flow pattern by inserting the eyewash
tester (Encon part number 01110469) into the dual stream
eyewash. The
stream
should meet the pattern design on the tester when lowered not more than 1½" (38.1
mm) from the point of initial contact. If the test fails, you
may need
to remove the
eyewash to remove an obstruction. For more information,
see “4.4 Dismantling and Reassembling the Eyewash and Drench Hose” on page 4-
3.
2. If applicable, ensure the alarms operate as designed.
3. Stop the water flow by pulling the push plate to its original position.
4. Ensure the eyewash completely drains. The three-way self draining eyewash requires
30 to 90 seconds to completely drain. Dripping from the bottom port at this time is
normal.
5. Reinstall the covers on the eyewash nozzle to prevent debris from entering the
eyewash nozzles. The covers also prevent shower water from entering the heads
and potentially freezing inside the eyewash.
6. Inspect the eyewash 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.
c. The valves must be drip free.
