Health & Safety in the Workplace
Unit 3.0 SafetyAwareness
Objective 3.3: Energy Isolation(Lock-Out
Tag-Out

2. What isLock-out?
(3.3.1)
•Lock-outis a system of locks, which secures
devices that control hazardous energy from
release (main disconnect switches, circuit
breakers, valves andclutches).
•Hazardous energy in plant couldbe:
–Super heatedsteam
–Extremely hot boiler feedwater
–Electrical supplies as well aschemicals
used to treat theboilers

The purpose of a “Lockout/Tagout” procedure is to protect employees
from machines and equipment capable of causing injury due to
unexpected energization, release of stored energy or the start-up of
equipment while an employee is performing maintenance or servicing
equipment.

3. What isLock-out?
(3.3.1)
Sources of Hazardous Energy in theWorkplace
Electrical
•Generated
•Static
Mechanical
•Translational
•Rotational
Thermal
•Machinesor
Equipment
•ChemicalReactions
Potential
•Pressure
•Hydraulic
•Pneumatic
•Vacuum
•Springs
•Gravity

4. What isLock-out?
(3.3.1)
LockoutDevices
•Pluglocks
•Ball ValveLockout
•Gate ValveLockout
•Individual LockoutHasp
•Group LockoutHasp

5. Risk associated with poweron.
(3.3.1)
Why Should YouCare?
➢Energy sources in machines and
equipment can be hazardous to
workers.
➢During the servicing and
maintenance of machines and
equipment, the unexpected startup
or release of stored energy can
result in serious injury or death to
workers.

6. Risk associated with poweron.
(3.3.1)
Why Should YouCare?
Consider just a fewexamples:
➢A worker is servicing a press, another worker comes by and starts the
press, and the service worker is caught up in the press, causing an
amputation
➢Workersarerepairingaconnectioninpiping,andsomewhereupthat

➢A conveyor jams, a worker reaches in to try to clear the jam, the
conveyor jam is suddenly and unexpectedly freed, and the worker is
crushed as aresult
➢A worker is servicing a machine, and at the same time internal wiring in
the machine shorts, causing the maintenance worker to beshocked

7. What isTag-out?
(3.3.2)
•A method of securing a power source through
use of a distinguishable dangertag.

8. What isTag-out?
(3.3.2)
Purpose oftags.
•Tag-out refers to the tag to
inform as to whohas
locked it out as well as
some additional information
such as whenit will be
turned back on or
energized.

9. Purpose ofLock-out/Tag-out.
(3.3.2)
•The purposeof lock-out/tag-out is to
prevent energy from accidentally being
released while a machine or
equipment is beingserviced.
•The ultimate goal of lock-out/tag-out is
toprotect the safety and health of
employees.
•Secondary is the protection of
equipment fromdamage.

10. Purpose ofLock-Out/Tag-Out?
(3.3.2)
•OSHA is the Occupational Safety & Health
Administration of the USGovernment.
•The OSHA Lock Out Tag Out (LOTO)
standard was developed to safeguard
employees from hazardous energy while
they are performing service on machines
andequipment.
•OSHA requires that before service or
maintenance is performed on machinery or
equipment, the machine or equipment be
turned off and disconnected from the
energy source, and the energy-isolating
must be either locked and taggedout.

11. Questions
•Define the concept of“lock-out”.
•Explain the purpose of tags.

12. Questions
•List theinformation tags shouldcontain.

13. Lock-out/Tag-outDefinitions
(3.3.1) (3.3.2)
Energized:
-Connected to an energy source or containing residual or
storedenergy.
Energy IsolatingDevice:
–A mechanical device that
physically prevents the
transmission or release ofenergy.
–Job requires employee to work in
an area in which service or
maintenance is beingperformed

14. Lock-out/Tag-outDefinitions
(3.3.1) (3.3.2)
LockoutDevice
Device using a positive means such asa
lock to hold an energy isolating device in
the safe positionand prevents the
energizing ofequipment.
Tag-outDevice
A warning device, such as a tag, thatis
securely fastened to an energy
isolating devicein accordance with an
established procedure to indicate the
equipment being controlled can not be
operated until the tag isremoved

15. Lock-out/Tag-outDefinitions
(3.3.1)(3.3.2)
DeviceRequirements
Both Lockout and Tagout devices mustbe:
•Durable –must be able to withstand environment and durationfor
use.
•Standardized –according to either color, shape, size, print,and
format.
•Substantial –to minimize early or accidental re-energizing.Locks
must be substantial to prevent removal. Tags must be attached
securely andunmovable.
•Identifiable –clearly identify
employee who applied thedevice.

16. Responsibility forLOTO?
(3.3.4)
Management is responsible for:
•Drafting, periodically reviewing,and
updating the writtenprogram.

anybodyelse.
•Always be sure all lockout/tagout devices are compatible
with the environment in which they will be used i.e.
corrosive, humid,etc.
