This document discusses lockout/tagout procedures and requirements. It begins by explaining that OSHA standard 1910.147 aims to control hazardous energy during maintenance. It then discusses why lockout/tagout is important for employee safety, legal compliance, and financial risk mitigation. The document outlines the key elements required for an effective lockout/tagout program, including procedures, training, device requirements, and inspections. It concludes by providing guidance on how to establish a comprehensive lockout/tagout energy control program.
2. What is 1910.147?
• OSHA standard for Lockout /Tagout
• Goal: Control the release of hazardous energy
during maintenance and servicing
• Many types of energy:
– Mechanical
– Hydraulic
– Electrical
– Gas
– Pneumatic
– Water
– Chemical
– Thermal

5. Employee Safety
• Approximately 3 million workers in the
US service equipment and face the
greatest risk of injury if Lockout/Tagout is
not properly implemented
• Lockout/Tagout prevents an estimated
120 fatalities and 50,000 injuries each
year in the US.

6. Legal Risk
• Created under the Occupational Safety
and Health Act of 1970
• Only government regulatory agency for
workplace safety
• Instructs, conducts inspections and
enforces workplace safety
• Does not apply to government facilities
SM
7. Legal Risk
OSHA General Duty Clause States:
“each employer shall furnish to each of his employees
employment and a place of employment which are free
from recognized hazards that are causing or are likely to
cause death or serious physical harm to his employees.”
Source: OSHA 29 USC 654
SM
8. Legal Risk
OSHA Standard 29 CFR 1910.147:
• 29 CFR 1910.147 was adopted in 1989
and established minimum
performance requirements for the
control of hazardous energy
• The lockout/tagout standard applies
to general industry employment
• It covers the servicing and
maintenance of machines and
equipment in which the unexpected
start-up or the release of stored
energy could cause injury
• It covers about 39 million workers
SM
9. Legal Risk
NFPA 70E – Chapter 1 Article 110 States:
“covers electrical safety-related work practices and
procedures for employees who work on or near exposed
energized electrical conductors or circuit parts in
workplaces that are included in the scope of this standard”
“Intended to provide for employee safety relative to
electrical hazards in the workplace”
Source: NFPA Regulations – Chapter 1, Article 110, 2004
SM
10. Legal Risk
• Required by law for employers to follow
• Requirements in General Terms
• Lots of details but also rely on consensus
industry standards for guidelines
NFPA 70E – 2004 (Originated 1976):
• Details – safe installation, maintenance and
work practices, signs, PPE (Personal
Protective Equipment)
SM
11. Financial Risk
Downtime
• Personnel
• Equipment
Legal Action
• Liability and Injury
• Cost of outside counsel
Fines and Penalties:
• LOTO is #3 most cited by OSHA
• Fiscal Year 2006
38,579 federal OSHA site inspections
58,058 state OSHA site inspections
Source: Occupational Hazards, February 2008
3,659 violations for LOTO totaling about $6M
SM
13. Risk Mitigation
Conclusion:
“The costs in terms of human suffering,
lost productivity, worker’s
compensation claims and lawsuits can
far outweigh the investment in a
comprehensive program.”

servicing or maintenance on that machine or
equipment
Affected employees – employee whose job requires
him/her to operate or use a machine or equipment

Between inspector and authorized/affected employees
• Lockout – review employees responsibilities under the
energy control procedure inspected
• Tagout – review employee responsibilities and Tagout
limitations
Document inspection
Correct any deviations or inadequacies identified
SM
29. Outside Personnel
• Example: Contractors
• “On-site employer and outside employer shall inform each
other of their respective lockout or tagout procedures”
• “On-site employer shall ensure that his/her employees
understand and comply with the restrictions and prohibitions
of the outside employer’s energy control program”
SM
30. Group Lockout/Tagout
OSHA 1910.147(f)(3)(i)
“When servicing or maintenance is performed by a crew, craft,
department or other group, they shall utilize a procedure
which affords the employees a level of protection equivalent
to that provided by the implementation of a personal lockout
or tagout device”
ONE authorized employee is responsible
for overall procedure in the crew.
If multiple crews are involved, there must
still be an overall authorized employee
responsible.
Group Lockout devices such as Group
Lockboxes and/or hasps must be used.
SM
31. Shift or Personnel Changes
• “Ensure continuity of lockout
or tagout protection”
• Employee from incoming shift
MUST apply his/her lockout
device before employee from
outgoing shift removes
his/her device.
• Communicate about the work
that has been done
SM
32. Unavailable Employee
• If authorized employee is not available to
remove his device, then the employer may
remove it IF:
– Employer has procedures and training for such
removal in energy control program
– Verification that authorized employee is not at
the facility
– Making all reasonable efforts to contact
authorized employee to inform him/her that
lockout device has been removed
– Ensuring that authorized employee is aware
that his device was removed before resuming
work at that facility
SM
35. 1. Assessment
Conduct a hazard
assessment by
identifying all equipment
that is used, serviced,
maintained or stored
SM
36. 2. Procedures
Determine Lockout/Tagout requirements for
all equipment, identifying and documenting
all energy sources – and create machine-
specific procedures containing:
Type of Hazard
Location on the equipment
Proper isolation and lockout
device/procedure
How to dissipate the stored
energy
How to verify the isolation
After this step, you should have an
energy control program for your facility
and machine-specific procedures
SM
37. 3. Devices
Circuit Breakers Electric Plug Toggle Switch Rocker Switch Cable Lockout
Pneumatic Ball valve Gate Valve Group Lock Box Tags
LOTO Stations LOTO Kits Hasps Padlocks Other
SM
38. 4. Training
A. Train all employees in facility
Authorized employees:
• Recognition of applicable hazardous energy
sources
• Type and magnitude of energy available in the
workplace
• Methods and means necessary for energy
isolation and control
• Ways to verify that the energy isolation is
effective
Affected and Other employees:
• Instruction in the purpose and use of energy
control procedure
• Should never attempt to restart or re-energize
machines or equipment which are locked out
or tagged out
• Respect use of warning tags
B. Document the training
SM
39. 5. Processes
Processes need to be put in place to
maintain the comprehensive
program for the following:
Periodic Inspections must take
place at least annually to
identify and correct any
deviations or inadequacies.
Retraining must take place
anytime there is a change in
responsibilities, equipment or
procedures along with new
employees
SM
41. Key Take-Aways
1. Only work on equipment “hot” or “live” if it absolutely
unavoidable
2. Lockout over Tagout
3. Facility specific and machine specific
4. Don’t forget about secondary energy sources or stored energy
5. Use annual inspections, regular training (annually suggested),
and discipline to avoid complacency
6. Lockout/Tagout is only one part of a complete and effective
safety program (safety ID, PPE, etc.)
