Safety Device Lock-Outs 
Some safety devices disconnect electrical energy from a circuit. The safety devices that are 
used on these additive feeders are primarily concerned with electrical power disconnection 
and the disabling of moving parts that may need to be accessed during the normal operation 
of the machine. 
Some of the safety devices utilize a manual activator.  This is the method of initiating the 
safety lock out.  This may be in the form of a plug, lever or a handle.  Within this lockable 
handle, there may be a location for a padlock.  Personnel servicing the equipment should 
place a padlock in the lockout handle. 
In addition to the safety devices listed above, these additive feeders are equipped with a line 
cord plug.  This allows the operator or maintenance personnel to unplug the additive feeder 
from its power source and tag it out.  The plug can then be tagged with any number of 
approved electrical lockout tags available at most electrical supply stores. 
WARNING!  Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air) 
sources prior to servicing or cleaning the additive feeder. Failure to do so may result in 
serious injury. No one but the person who installed the lockout may remove it.
