LOTO Lockout/Tagout

Objectives

Clarify requirements of the Lockout/Tagout
(LOTO) Program
Ensure everyone is aware of their role within LOTO
Program

“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
starting work

80% failed to turn off equipment
10% equipment
activated by someone
else
5% failed to control
potential energy
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.

“Other employee”
Works in an area where LOTO
being used.

Affected Employee

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
this section.

Types of Hazards

Electrical
 Pneumatic
 Hydraulic
 Mechanical
 Thermal
 Chemical
 Radiation
 Steam
 Spring-Driven
 Suspended Parts
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”.

Adjusting
 Inspecting
 Modifying
 Replacing parts
 Tool changes
 Clearing jams
 Lubricating
 Cleaning

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
devices…”
Device that physically prevents the
transmission or release of energy

Examples:
 Electrical disconnect
switch
 Electrical breaker switch
 Hydraulic valve
 Pneumatic valve
 Line valve

Pushbuttons,
selector switches, and
other control circuit
devices are NOT
energy isolation
devices

Preferred means of
controlling hazardous
energy at Kerry is
LOCKOUT IN
CONJUNCTION WITH
TAGOUT.
 Each isolation point must
have both a lock and a tag
attached to it.
 Tags must indicate lock
holders name &
department.

STEP 1
Advise
employees
STEP 2
ID energy
STEP 4
Isolate
energy
STEP 5
Apply locks
STEP 3
Shutdown
machine
STEP 6
Dissipate,
Releases
STEP 7
Verify off

Verbally notify all “affected” and “other”
employees of impending shutdown.
 Not all equipment will have someone
“assigned” to it.

Know types & magnitude of energy
associated with equipm
