Clarify requirements of the Lockout/Tagout
Ensure everyone is aware of their role within LOTO
“LOTO” is a technique used to prevent
energy from being released during the
servicing of equipment. This is
accomplished by placing locks and tags
on energy isolation devices prior to
80% failed to turn off equipment
activated by someone
5% failed to control
Most of remaining 5%
disconnected power but
failed to verify effectiveness
All employees fit into one of the following LOTO roles:
“Authorized employee” ( Top level of qualification)
Services equipment & authorized to apply LOTO.
“Affected employee” Operates or
uses equipment being serviced under LOTO.
Works in an area where LOTO
An employee whose job requires
him/her to operate or use a machine
or equipment on which servicing or
maintenance is being performed
under lockout or tag out, or whose job
requires him/her to work in an area in
which such servicing or maintenance
is being performed.
An affected employee becomes an
authorized employee when that
employee's duties include performing
servicing or maintenance covered under
Types of Hazards
Some energy sources can be turned on/off.
Others can only be dissipated or controlled.
Potential energy can be converted to kinetic!
Goal of LOTO is to achieve “Zero Energy State”
When is LOTO applied?
“…during the servicing of equipment”.
Exceptions to LOTO
Cord & plug connected equipment
Plug is only source of energy
Plug is under continuous control of one person
Energy Isolation Devices
“…accomplished by placing locks on energy isolation
Device that physically prevents the
transmission or release of energy
Electrical breaker switch
selector switches, and
other control circuit
devices are NOT
Preferred means of
energy at Kerry is
Each isolation point must
have both a lock and a tag
attached to it.
Tags must indicate lock
holders name &
Verbally notify all “affected” and “other”
employees of impending shutdown.
Not all equipment will have someone
“assigned” to it.
Know types & magnitude of energy
