USC LPX 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."
There are two Emergency Stop push buttons on the LPX Automated Seed
Treater, which are located on the main control panel and the treater
junction box. Actuators of emergency stop shall be colored RED. The
background immediately around the device actuator shall be colored
YELLOW. The actuator pushbutton-operated device shall be of the palm
or mushroom head type.
This is the stopping of machine motion by reducing the electrical command signal to
0 (zero) once the stop signal has been recognized.
Electrocution Hazard
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.
Automatic Start Hazard
This Semi - Automated Pump Stand 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.
