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.
