sonnel are clear of associated equipment.

trical equipment or wiring. On completion, close and lock panel

hardware.
2. Turn off electrical power (lock out) before cleaning control system
assemblies.
3. Keep electrical panel covers closed and power off when cleaning an
enclosure.
4. Always clean up spills around the equipment immediately after they
occur.
