Periodic Checkout Procedures
EZ-SCREEN Grid
Instruction Manual
6.4 Daily Checkout
Perform this checkout procedure at every shift change, power-up and machine
set-up change. During continuous machine run periods, this checkout must be
performed at intervals not to exceed 24 hours. A Designated Person or
Qualified Person (as defined in the Safety Glossary) must perform the procedure;
checkout results should be recorded and kept on or near the guarded machine,
per OSHA 1910.217(e)(1).
1) Verify that access to the guarded area is not possible from any area not
protected by the EZ-SCREEN Grid System. Hard guarding, or supplemental
presence-sensing devices must be installed, wherever needed, to prevent
any person from reaching around the light grid or entering into the hazard
area. Verify that all supplemental guarding devices and hard guarding are in
place and operating properly.
2) Verify that the minimum separation distance from the closest danger point of
the guarded machine to the light grid is not less than the separation distance
calculated in Section 3.3.1 and recorded here: ____________.
3) Verify that it is not possible for a person to stand within the guarded area,
undetected by the EZ-SCREEN Grid System or by other supplemental
guarding (as described in ANSI/RIA R15.06, or other appropriate standards).
4) Verify that the Reset switch is mounted outside the guarded area, out of
reach of anyone inside the guarded area, and that the key or other means of
preventing inadvertent use is in place.
5) Test the effectiveness of the EZ-SCREEN Grid System with power ON, using
the trip test (Section 6.2).
6) Initiate machine motion of the guarded machine and, while it is moving, use
the supplied test piece to block one of the grid beams. Do not attempt to
insert the test piece into the dangerous parts of the machine. Upon blocking
any beam, the dangerous parts of the machine should come to a stop with
no apparent delay. Upon removal of the test piece from the beam, verify that
the machine does not automatically restart, and that the initiation devices
must be engaged to restart the machine.
7) With the guarded machine at rest, block one of the grid beams and verify
that it is not possible for the guarded machine to be put into motion while
the test piece is blocking a beam.
8) Check carefully for external signs of damage or changes to the EZ-SCREEN
Grid System, the guarded machine, and their electrical wiring. Any damage
or changes found should be immediately reported to management.
