Title: CONTROL OF HAZARDOUS ENERGY LOCKOUT/TAGOUT (LOTO)


1
CONTROL OF HAZARDOUS ENERGYLOCKOUT/TAGOUT
(LOTO)
2
LOCKOUT/TAGOUT
  • The OSHA Standard for the Control of Hazardous
    Energy (Lockout/Tagout) 29 CFR 1910.147 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.

3
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
TYPES OF ENERGY
  • CHEMICAL
  • ELECTRICAL
  • HYDRAULIC
  • MECHANICAL
  • THERMAL
  • PNEUMATIC
  • ? Some energy sources can be turned on/off.
  • ? Others can only be dissipated or controlled.

5
CHEMICAL
  • HAS ENERGY THAT CAN START FIRES, CAUSE SKIN
    BURNS, GENERATE HARMFUL GASES OR FUMES
  • BEFORE WORKING-RELEASE, DRAIN OR VENT CHEMICALS
    SAFELY

6
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

7
HYDRAULIC
  • ENERGY OF LIQUIDS UNDER PRESSURE
  • RELIEVE PRESSURE SLOWLY INTO A PROPER CONTAINER
  • RAPID RELEASE CAN CAUSE INJURY
  • PRESSURE CAN CAUSE EQUIPMENT TO MOVE

8
MECHANICAL
  • KINETIC-IN MOTION
  • ENERGY OF MOVING MACHINERY CAN CAUSE,
    AMPUTATIONS, LACERATIONS, FRACTURES LOSS OF
    LIFE
  • POTENTIAL-STORED ENERGY

9
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

10
PNEUMATIC
  • ENERGY OF COMPRESSED GASES
  • - UNCONTROLLED RELEASE CAN CAUSE INJURY
  • -RAPID DE-PRESSURIZATION CREATES EXTREME LOW
    TEMPERATURE
  • PROPERLY VENT ALL SYSTEMS BEFORE STARTING WORK

11
FIRST STEPS IN LOTO
  • KNOW YOUR EQUIPMENT
  • SYSTEMS
  • hazards
  • isolation points
  • procedures
  • Working on unfamiliar machinery is a hazard

12
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

13
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.

14
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.

15
LOTO PROTECTS YOU!!!
  • USE PROPER PROCEDURES.
  • PLEASE BE CAREFUL WHEN WORKING ON EQUIPMENT

16
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

17
WHEN IS LOTO APPLIED?
  • Adjusting
  • Inspecting
  • Modifying
  • Replacing parts
  • Clearing jams
  • Lubricating
  • Cleaning
  • Tool changes
  • There are some situations where LOTO is not
    required

18
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

19
GENERAL LOTO PROCEDURE
20
LOCKOUT/TAGOUTTYPES OF DEVICES
21
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.

22
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.

23
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.

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.
