2. What Is
Hazardous Energy?
– Often invisible
– Can be hydraulic or
mechanical
– Live or stored
– Moving machine or
equipment parts
3. Gravity
• Gravity can be
hazardous energy
and needs to be
controlled.
• Lower items to the
ground, or block
them up if they can
fall.
• Place chocks by
wheels.
4. Hazardous Energy Injuries
– 7,600 injuries per year
– 80% of workers fail to
turn off equipment
– Causes:
• Unexpected start-up
• Release of stored
energy
• Failure to
lockout/tagout
5. Controlling
Hazardous Energy
– Follow lockout and
tagout procedures
– Prevent machinery or
equipment from being
turned on
– Dissipate energy
– Prevent a part of
machinery or
equipment from moving
– Provide means of
warning (tag)
6. Lockout/Tagout Regulations
•29 CFR 1910.147
– “Authorized
employee” who
services machinery
– “Affected employee”
who operates
machinery
– “Other employee”
near machinery and
equipment
7. – Trained to
perform locking
or tagging
procedures
– No other
employee can
attach or remove
lock or
tag devices
Authorized Employee
8. Authorized Employee
Responsibilities
– Repair or service
equipment as needed
– Ensure that all energy
sources are locked
out
– Test equipment to
verify residual energy
is dissipated
– Place tags & locks on
equipment
11. Affected Employee Responsibilities
– Notify maintenance
– Leave all lockout/
tagout devices in
place
– Verify equipment is
safe to operate
– Ensure safety guards
are in place and
functioning
– Follow all safety rules
12. – Circuit breaker

picture?
Energy Isolation Device
• Isolate the equipment
from the energy source
• Isolation device
13. Arc Flash Left Hand Rule
• Stand to the right side of the switch, not in front of the box.
• Grab the disconnect with your LEFT hand
• Turn your body and face away from the switch
• Close your eyes.
• Take a deep breathe and hold it.
• Then "throw" the disconnect lever.
14. Selector Switches Are Not Energy
Control Devices
They SHALL NOT be used to lockout equipment.
Only two position (on-off) switches may be used as energy
control devices.
16. This IS NOT A Lockout Device and
May Not Be Used for Controlling
Hazardous Energy
17. Lockout Device Requirement
1910.147(c)(5)(ii)Lockout devices and tagout
devices shall be singularly identified; shall be the
only devices(s) used for controlling energy; shall
not be used for other purposes;
In other words, at KU Masterlock 6835RED may
be used for LOTO only, it may not be used on
lockers, toolboxes, etc.
18. When to Use Lockout/Tagout
Devices
•Use lockout/tagout
when:
– Equipment needs
servicing
– Hazardous energy
exists
– Unexpected start-up
could occur
– When in doubt,
LOCK IT OUT!
19. Actions That Trigger Lockout/Tagout
– Removing or
bypassing a
safety device
– Any part of the
body is placed in
harm’s way
– Exposure to
hazardous
energy
20. Lockout/Tagout Exceptions
– When hazardous
energy does not exist
– During routine
production processes
– Cord-controlled
devices if the plug is
under your control
and within arm’s
reach. If not use a
plug cover.
– Hot tap operations
21. Notify affected employees
Shut down energized
equipment
Isolate energy sources
Lock out or tag out
Release stored energy
Try to restart equipment.
Lock-Tag-Try
23. Restart Procedure (continued)
• Remove lockout devices and
reenergize the machine
• Ensure that all safety devices have
been replaced
• Reactivate isolation devices
• Restart machinery or equipment
24. Standard Lockout & Tagout Devices
NO OTHER LOCKS OR TAGS MAY BE USED!
LOTO LOCKS MAY BE USED FOR
LOCKOUT/TAGOUT ONLY!

25. Multi Shift Repairs
• The lead authorized employee, or designee, will leave his/her
lock in place while all others are removed.
• Oncoming lead employee will ensure equipment is properly
locked out.
• Off going lead will remove his/her lock in the presence of the
oncoming lead. Oncoming lead will immediately install his/her
lock.
26. Group Lockout
• If something must be locked and tagged out
everyone working on that equipment must
apply a lock and tag. There are two ways to do
this:
Multi-hasp Lock box
27. How to Use the Lock Box
• The lead apply authorized employee will apply
locks to all required energy control devices, and
place his/her keys in the box.
• The remaining authorized employees will verify
that the equipment is properly locked out, and
place their locks on the outside of the box,
locking the lead employees’ key(s) inside.
• ONLY THE LEAD AUTHORIZED EMPLOYEE SHOULD
PLACE THEIR KEYS IN THE BOX.

Services Lock Removal Form.
• Information regarding lock removal must be given to the
authorized employee before he/she resumes work at the
University.
29.
30. Reviewing the Basics
• LOTO must be used if equipment is subject to re-
energization or accidental start up.
• LOTO locks may not be used for other purposes.
• Other locks may not be used for LOTO.
• Never remove someone else’s lock without
