The purpose of Lockout Tagout


The purpose of
lockout tagout is to
protect employees
from exposure to
uncontrolled
hazardous energy.
This is accomplished
by the use of locks
and tags to protect
employees.
Lockout Tagout Standard Requirements

29 CFR 1910.147 requires that employers:
◦ Develop a written plan for dealing with the isolation of
hazardous energy from machines and equipment where
unexpected startup could occur, or the release of stored
energy could injure employees.
◦ Employers must:
Provide energy isolation devices to employees.
Provide proper lockout tags.
Provide lockout tagout procedures.
Provide training for Authorized, Affected, and Other
employees.
 Perform periodic inspections to ensure that lockout tagout
policies are being properly followed.

Exceptions to the Rule

LOTO is not required when:
◦ Hazardous energy does not exist.
◦ Activities are performed during
routine production processes.
◦ Work on cord-controlled devices,
where the technician has direct
control of the cord.
◦ Hot tap operations where
shutdown is not possible.
(Special procedures must be used!)

What equipment in your work place requires
Lockout Tagout?
ne of the fundamental keys to
keeping each employee safe is that
each employee will apply their own
lock and tag to the equipment being
locked out. The lock that they apply
will only have one key, and it will be
in their possession. The energy
cannot be released accidentally or
purposely until all locks have been
removed. This ensures that all
employees are out of danger before
energy is applied.
Lockout Tagout Isolation Devices

There are many
different type of
isolation devices:
◦
◦
◦
◦
◦
◦
◦
Locks
Valve Covers
Chains
Multi-lock hasps
Blocks
Ball valve covers
Piping Blanks
What lockout tagout
devices are used at
your facility?
Lockout Tagout Device Requirements

Durable
◦ Tags and locks must be tough enough to
withstand the environment they are placed
in.

Standardized
◦ The company needs to use the same
equipment across the business.

Substantial
◦ The equipment must be large enough to
be recognizable.

Identifiable
◦ The equipment must be recognizable by
employees.
Lockout Tagout – Affected Employees

“Affected Employees”
are employees that:
◦ Operate equipment.
◦ Infrequently adjust LOTO
equipment.
◦ Work in the area of
equipment that requires
LOTO.
Affected Employees can be
nearly everyone in a facility.
Affected Employees must be
trained in and have the ability
to recognize LOTO
requirements.
Affected Employee Responsibilities

It is the responsibility of the affected employee
to:
◦ Leave lockout tagout devices undisturbed.
◦ Notify proper personnel when equipment needs
maintenance or adjustment.
◦ Check that equipment operates safely after
LOTO.
◦ Follow procedures and safety rules when
operating equipment.
Lockout Tagout – Authorized Employees

Authorized Employees
are employees who:
◦ Maintain equipment.
◦ Perform maintenance on
equipment.
◦ Perform detailed
inspections of
equipment.
It is critical that Authorized Employees are fully trained in LOTO, and
have a strong understanding of the LOTO procedures that are specific
to their equipment.
Authorized Employee Responsibilities

Place a Danger tag on locked out equipment.

Inform affected employees of the lockout tagout
operation.

Ensure that all energy sources are isolated.

Test the equipment to verify energy is dissipated.

Repair equipment as needed.

Remove LOTO devices when completed and
restart equipment.

Group Lockout Tagout



What do you do when more
than one person will be
working on a locked out
piece of equipment?
Each person must hang their
own lock on the device.
This can be accomplished by
using multi-lock hasps and
group lock boxes.
Using a Tagout System

Tags cannot be used as a substitute for locks. They
can invoke a false sense of security.

They can only be used alone if there is no other way
to positively control the hazardous energy.
◦ They don’t provide the physical protection that
locking devices do.
◦ They can only be removed with authorization of
the authorized person who hung the tag. The tag
cannot be bypassed, ignored, or otherwise
defeated.


Tags and their means of attachment must be made
of materials that can withstand the environmental
conditions of the workplace.
Tags must be securely attached so that they cannot
be accidently detached.

Forcible Removal of a LOTO Device

Need for lock and tag removal is identified to
person's supervisor.

Attempt to contact the owner is documented on
the Abandoned Lock Removal Form.

An evaluation of the entire system must be made
to ensure that an injury can not occur before the
lock is removed. (Names are documented on the
form.)

Bolt cutters or other removal device are
acquired.

Supervisor or designee removes the lock. (Names
are documented on the form.)
Written Lockout Tagout Standard
