Title: Control of Hazardous Energy (Lockout/Tagout) 29 CFR 1910.147


1
Control of Hazardous Energy (Lockout/Tagout) 29
CFR 1910.147
2
What Is Lockout/Tagout?
  • Referred to as LOTO
  • Blocks flow of energy from power source to the
    equipment
  • Provides means of warning (tag)

3
Regulatory Requirements
  • 29 CFR 1910.147Control of Hazardous Energy
  • Covers operators and service personnel
  • Requires training of employees

4
Types of Lockout Devices
  • Locks
  • Blocks
  • Chains
  • Multilock hasps
  • Wheel valve covers
  • Ball valve covers

5
Requirements For Lockout/Tagout Devices
  • They must be
  • Durable
  • Standardized
  • Substantial
  • Identifiable

6
Energy Sources
  • Electricity
  • Hydraulic
  • Pneumatic
  • Steam
  • Thermal
  • Chemical
  • Gravity

7
Typical Equipment Requiring LOTO
  • Presses
  • Saws
  • Conveyors
  • Pumps
  • Production Equipment
  • Trash Compactors
  • Ovens

8
When Must LOTO Be Used?
  • When servicing or maintaining equipment where
  • Hazardous energy exists
  • Unexpected start-up could occur
  • Either of these could harm an employee

9
LOTO Shall Be Used When
  • Employees are required to remove or bypass a
    safety device
  • Employees are required to place any part of
    their body in harms way
  • Employees are exposed to hazardous energy

10
LOTO Exceptions
  • Work where hazardous energy does not exist
  • Activities performed during routine production
    processes
  • Work on cord-controlled devices
  • Hot tap operations where shutdown is not feasible

11
Typical LOTO Procedures
  • Performing a shutdown
  • Isolating equipment
  • Applying and removing lockout devices
  • Safely releasing stored energy

12
Affected Employees
  • Employees who
  • Operate
  • Work around
  • Occasionally adjust equipment that is subject to
    LOTO

13
Authorized Employee
  • Maintains equipment
  • Services equipment
  • Is trained to use LOTO

14
Company Responsibilities
  • Ensure de-energization of equipment
  • Ensure employee awareness
  • Provide appropriate levels of training
  • Review program effectiveness
  • Maintain and revise program
  • Administer appropriate disciplinary actions

15
Maintenance Responsibilities
  • Lockout/Tagout prior to service or repair
  • Remove or cut locks off isolation devices
  • Ensure proper training of authorized employees

16
Affected Employee Responsibilities
  • Notify maintenance, etc., when equipment needs
    repair or adjustment
  • Leave all LOTO devices in place
  • Verify equipment is safe to operate following
    LOTO
  • Follow all safety rules while operating the
    equipment

17
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 a DangerDo Not Operate tag on equipment

18
Authorized Employee Responsibilities (cont.)
  • Obtain assistance when necessary
  • Remove locks and/or tags following LOTO
  • Coordinate multi-shift repair

19
Training Requirements
  • Authorized employeesinitially and at least
    annually
  • Affected employeesat least initially
  • Authorized and affectedwhenever changes are made
    to jobs or procedures
  • Authorized and affectedwhen program deficiencies
    are noted

20
How to Perform LOTO Safely
  • Follow company safety procedures for LOTO
  • Refer to procedures on how to lockout specific
    equipment
  • Keep everyone informed when equipment is repaired
    or serviced
  • Stay alert
  • Use common sense

21

  • 3. It is not required that a company have
    written procedures for proper lockout/tagout.
    True or False
  • 4. An authorized employee is one who _________
    or _________ the equipment.
  • 5. If a safety device is removed from a piece of
    equipment, LOTO is not required. True or False

22
Quiz (cont.)
  • 6. Typical energy sources found on equipment
    include _______, _______, and _______.
  • 7. Affected employees are those who operate or
    work around a piece of equipment. True or
    False
  • 8. As long as an employee has had training on
    LOTO, the employer or company has no additional
    responsibilities under 1910.147. True or False
  • 9. Training for authorized employees must be
    conducted _________ and at least _________.
  • 10. Locks should always stay on the equipment
    during a shift change. True or False

23
Quiz Answers
  • 1. True. It should block the flow of energy and
    provide a means of warning.
  • 2. Types of LOTO devices include locks, blocks,
    chains, hasps, wheel valve covers and ball valve
    covers.
  • 3. False. If lockout is required, a company must
    have a written program and procedures.
  • 4. An authorized employee is one who services or
    maintains the equipment.
  • 5. False. LOTO is required when a safety device
    is removed, an employee is in harms way or when
    employees are exposed to hazardous energy.

24
Quiz Answers (cont.)
  • 6. Typical energy sources include electricity,
    hydraulics, pneumatics, steam, thermal, chemical
    and gravity.
  • 7. True. Affected employees are those who
