1. A PRESENTATION ON LOCKOUT/ TAGOUT” (LOTO) BY ORILOYE JIDE 13/03/2015

2. WHAT IS LOCKOUT/TAGOUT?
“LOTO” is a technique used to prevent energy from being released during the servicing of equipment. This is accomplished by placing locks on energy isolation devices prior to starting work.

4. LOCKOUT/TAGOUT
The OSHA Standard for the Control of Hazardous Energy (Lockout/Tagout) 29 CFR covers the servicing and maintenance of machines and equipment in which the unexpected start-up or the release of stored energy could cause injury to employees.

5. TYPES OF ENERGY CHEMICAL ELECTRICAL HYDRAULIC MECHANICAL THERMAL
PNEUMATIC
 Some energy sources can be turned on/off.
 Others can only be dissipated or controlled.

6. CHEMICAL
HAS ENERGY THAT CAN START FIRES, CAUSE SKIN BURNS, GENERATE HARMFUL GASES OR FUMES
BEFORE WORKING-RELEASE, DRAIN OR VENT CHEMICALS SAFELY

7. Electrical AS LOW AS 30 VOLTS CAN CARRY ENOUGH CURRENT TO KILL
USE NON-CONDUCTING TOOLS
DISCHARGE ALL CAPACITORS AFETR LOCKOUT
ENSURE ALL CONTROL POWER IS DE-ENERGIZED
LOCK & TAG SOURCE BREAKERS NOT SWITCHES
STORED POTENTIAL ENERGY CAN BE RELEASED DURING WORK CAUSING INJURY OR DEATH
CHECK CIRCUTS DEAD BEFORE WORKING

8. HYDRAULIC ENERGY OF LIQUIDS UNDER PRESSURE
RELIEVE PRESSURE SLOWLY INTO A PROPER CONTAINER
RAPID RELEASE CAN CAUSE INJURY
PRESSURE CAN CAUSE EQUIPMENT TO MOVE

9. MECHANICAL KINETIC-IN MOTION
ENERGY OF MOVING MACHINERY CAN CAUSE, AMPUTATIONS, LACERATIONS, FRACTURES & LOSS OF LIFE
POTENTIAL-STORED ENERGY

10. THERMAL ENERGY OF HEAT (& COLD) HOT EQUIPMENT & FLUIDSD WILL BURN YOU
COLD FLUIDS CAN CAUSE INJURY ALSO
QUICK RELEASE OF COMPRESSED GASES CAN FREEZE YOUR SKIN
ALLOW EQUIPMENT TO REACH A SAFE TEMPERATURE BEFORE STARTING WORK

11. PNEUMATIC ENERGY OF COMPRESSED GASES
- UNCONTROLLED RELEASE CAN CAUSE INJURY
-RAPID DE-PRESSURIZATION CREATES EXTREME LOW TEMPERATURE
PROPERLY VENT ALL SYSTEMS BEFORE STARTING WORK

12. Working on unfamiliar machinery is a hazard
FIRST STEPS IN LOTO
KNOW YOUR EQUIPMENT
& SYSTEMS:
hazards
isolation points
procedures
Working on unfamiliar machinery is a hazard

13. WHAT YOU NEED FOR LOTO WRITTEN LOTO SCHEDULE
LOCKS & TAGS-IDENTIFIED FOR THE WORKER
HASPS-FOR PLACING LOCKS & TAGS
BREAKER CLIPS-FOR ELECTRICAL LOTO
BLANK FLANGES-FOR FLUID LINES
VALVE COVERS-FOR LOTO OF VALVES
PLUG BUCKETS-FOR ELECTRICAL PLUGS

14. WHO CAN REMOVE LOCKS & TAGS???
ONLY THE EMPLOYEE WHO PLACED THE TAG “OR” A SUPERVISOR, AFTER OBTAINING PERMISSION FROM THE WORKER WHO PLACED THE TAG
EACH PERSON WORKING ON THE EQUIPMENT MUST PLACE THEIR OWN LOCKS & TAGS TO ENSURE THEIR SAFETY, EVEN IF THE EQUIPMENT ALREADY HAS A LOCK & TAG ON IT.

15. LOCKOUT/TAGOUT: SHIFT CHANGES
If servicing lasts more than one shift, lockout/tagout protection must not be interrupted.
When the employee who applied device is not there to remove it, it can be removed only in an emergency and only under the direction of the supervisor.

16. LOTO PROTECTS YOU!!! USE PROPER PROCEDURES….
PLEASE BE CAREFUL WHEN WORKING ON EQUIPMENT

17. How Injuries Occur During the Servicing of Equipment?
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

18. WHEN IS LOTO APPLIED? Tool changes Adjusting Inspecting Modifying
Replacing parts
Clearing jams
Lubricating
Cleaning
Tool changes
There are some situations where LOTO is not required…

19. EXCEPTIONS TO LOTO Normal production operations
Routine, repetitive, & integral to production
Guards/safety devices not bypassed
Body part not placed in the point of operation or other dangerous area during machine cycle
Need to use alternative measures for protection
Cord & plug connected equipment
Plug is only source of energy
Plug is under continuous control of one person

20. GENERAL LOTO PROCEDURE
STEP 1
ID Energy
Sources
STEP 2
Notify
Others
STEP 3 Shutdown Equipment
STEP 4
Isolate Equipment
STEP 5
LOTO Equipment
STEP 6
Release Stored Energy
STEP 7
Verify
Isolation
STEP 8 Perform Servicing
STEP 9 Release from LOTO

21. LOCKOUT/TAGOUT TYPES OF DEVICES

22. LOCKOUT/TAGOUT DEVICES
Durable – Lockout and tagout devices must withstand the environment to which they are exposed for the maximum duration of the expected exposure. Tagout devices must be constructed and printed so that they do not deteriorate or become illegible, especially when used in corrosive or wet environments.

23. DEFINITIONS:
Energy Isolating Device - A mechanical device that physically prevents the transmission or release of energy.
Energy Control Procedure - Safety program adopted by the employer that includes energy control procedures plus provisions for inspecting the procedures and training employees for lockout/tagout.
Authorized Employee - one who locks out machines or equipment in order to perform the servicing or maintenance on that machine or equipment.
Affected Employee - one whose job requires him/her to operate or use a machine or equipment on which servicing or maintenance is being performed under lockout, or whose job requires him/her to work in an area in which such servicing or maintenance is being performed.

24. SUMMARY
All hazardous energy sources must be controlled (kinetic & potential).
Control via energy isolation device (do not rely on control circuit).
Only use designated lock for LOTO.
Tags must accompany all locks.
Nine-step general procedure – remember to verify isolation.
Protection must be ensured during special situations.
OSHA STANDARD…

25. TIDBITS OF INFORMATION:
Never attempt lockout/tagout procedures unless you have been trained and certified by your employer under an approved Energy Control Program.
Never loan or share your lock, combination, or key with anybody else.
Always be sure all lockout/tagout devices are compatible with the environment in which they will be used i.e. corrosive, humid, etc.
