USC Seed Wheel Operator's Manual page 7

Lockout/Tagout is the placement of a lock/tag on an energy isolating device in
accordance with an established procedure. When taking equipment out of service to
perform maintenance or repair work, always follow the lockout/tagout procedures as
outlined in ANSI Z344.1 and/or OSHA Standard 1910.147. This standard "requires
employers to establish a program and utilize procedures for affixing appropriate
lockout devices or tagout devices to energy isolating devices and to otherwise disable
machines or equipment to prevent unexpected energizing, start-up, or release of
stored energy in order to prevent injury to employees."
This is the stopping of machine motion by reducing the electrical command signal to
0 (zero) once the stop signal has been recognized.

HAZARD REVIEW
Electrocution accidents are most likely to occur during
maintenance of the electrical system or when working on or
near exposed high voltage wiring. This hazard does not exist
when the electrical power has been disconnected, properly
locked, and tagged out.
The Seed Wheel may be controlled by an automated system and
may start without warning. Failure to properly disconnect, lockout,
and tagout all energy sources of remotely controlled equipment
creates a very hazardous situation and could cause injury or even
death. PLEASE STAY CLEAR AND BE ALERT.
