Review of lockout/tagout procedures

1. Confined Space
Lockout/Tagout and Entry Permits

2. Confined Space - defined
• Large enough and so configured that an
employee can bodily enter and perform
assigned work;
• Has limited or restricted means for entry or
exit; and
• Is not designed for continuous employee
occupancy.

3. Permit-required confined space
• Confined space that has one or more of the
following characteristics:
– Contains or may contain a hazardous atmosphere
– Contains a material that has the potential for
engulfment
– Is configured such that an entrant could be trapped or
asphyxiated by inwardly converging walls or
downward sloping floors that taper to a smaller cross
section
– Contains any other recognized serious safety or
health hazard.

4. Permit-required Confined Space Program
• The employer (space owner) shall implement
measures to prevent unauthorized entry
• Identify and evaluate hazards of permit spaces
before employees enter them
• Provide and maintain necessary equipment
for employees and ensure that it is used
properly
• Evaluate permit space conditions when
operations are conducted

5. Permit-required Confined Space Program
• Develop and implement the means, procedures and
practices necessary for safe permit space entry
operations, including:
– Specifying acceptable entry conditions
– Isolating the confined space
– Purging, inerting, flushing or ventilating the space
– Providing barriers to protect entrants from external
hazards
– Verifying that conditions in the space are acceptable for
entry throughout the duration of the entry
• Designate the persons who are to have active roles in
entry operations and identify the duties of each.

6. Permit-required Confined Space Program
• Provide at least on attendant outside the space
• Develop and implement procedures for
summoning rescue and emergency services
• Develop and implement a system of the issuance
of entry permits
• Review entry operations when it is believed that
measures may not protect employees
• Review and revise confined space program using
cancelled permits.

7. Training
• Employer must provide training so that all
employees can perform assigned duties safely
– Before first assigned duties
– Before change in duties
– Whenever there is a change in hazard of permit
space operations
– Whenever corrective actions are needed
• Must establish proficiency

8. Duties of entrants
• Know the hazards
• Properly use equipment
• Communicate with attendant
• Alert the attendant when:
– Dangerous situation is recognized
– Prohibited condition is detected
• Exit from the space immediately when:
– Order is given by attendant
– Dangerous situation is recognized
– Prohibited condition is detected
– Evacuation alarm is sounded

9. Duties of attendants
• Know the hazards
• Is aware of behavioral effects of exposure
• Maintains accurate count of entrants
• Remains outside the space during entry
• Communicates with entrants
• Monitors activities in and around the space

10. Duties of attendants
• Monitors activities in and around the space
• Summon rescue and emergency services
when needed
• Keep unauthorized persons away from the
space
• Performs non-entry rescues
• Performs no other duties that may interfere
with primary duty to monitor space

11. Duties of entry supervisors
• Know the hazards
• Verifies that entry is performed consistent
with the terms of the entry permit
• Terminates entry and cancels permit as
necessary
• Verifies that rescue services are available
• Keep unauthorized persons away from the
space

12. Rescue and Emergency Service
• Employer must ensure that
– Employees are properly trained and equipped
– Employees are trained according to requirements
of entrants
– Employees practice at least once every 12 months
n simulated or actual spaces representative of
those they would be expected to enter
– Employees are trained in basic first aid and CPR

13. Rescue and Emergency Service
• Rescue service must be:
– Informed of the hazards present
– Provided access to all permit spaces
• Entrants must use chest or full body harness with
retrieval line attached at center of back near
shoulder level or above head
• To ensure rescue can begin immediately, outer
end of retrieval line must be attached to
– Mechanical device for vertical spaces over 5 feet deep
– Fixed point outside space

14. Rescue and Emergency Service
• Retrieval equipment must be used unless:
– It would increase the overall risk
– Would not contribute to the rescue of entrant
• If entrant is exposed, MSDS shall be made
available to medical facility treating entrant.

15. Potential confined space hazards
• Atmospheric hazards
• Burn hazards
• Mechanical hazards
• Engulfment hazards
• Noise hazards
• Heat stress

16. • The overall objective of the hazard control
program is to ensure that the work area is
safe.

17. Control measures
• Cleaning, purging or inerting atmosphere
• Isolation from hazardous energy or materials
• Lockout/tagout
• Blanking, blinding or line breaking pipes
• Blocking or breaking mechanical linkages
• Mechanical ventilation

18. Control of Hazardous Energy
• OSHA 1910.147
• Steps for shutting down, isolating, blocking
and securing machines or equipment to
control hazardous energy
• Steps for the placement, removal and transfer
of lockout devices or tagout devices
• Requirements for testing to verify the
effectiveness of lockout devices, tagout
devices, and other energy control measures.

19. Control of Hazardous Energy
• Lockout devices shall be substantial enough to
prevent removal without the use of excessive
force or unusual techniques, such as with the
use of bolt cutters or other metal cutting tools
• Tagout devices shall be substantial enough to
prevent inadvertent or accidental removal.

20. Control of Hazardous Energy
• Tagout device attachment means shall be of a
non-reusable type, attachable by hand, self-
locking, and non-releasable with a minimum
unlocking strength of no less than 50 pounds.
• Lockout devices and tagout devices shall
indicate the identity of the employee applying
the device(s).

21. • Tags are warning devices affixed to energy
isolating devices, and do not provide the
physical restraint on those devices that is
provided by a lock
• When a tag is attached to an energy isolating
means, it is not to be removed without
authorization of the person responsible for it,
and it is never to be bypassed, ignored, or
otherwise defeated.

22. • Tags may evoke a false sense of security, and
their meaning needs to be understood as part
of the overall energy control program
• Where tagout devices are used with energy
isolating devices designed with the capability
of being locked, the tag attachment shall be
fastened at the same point at which the lock
would have been attached

23. Energy isolation
• Lockout or tagout shall be performed only by
the authorized employees who are
performing the servicing or maintenance
• Lockout devices, where used, shall be affixed
in a manner to that will hold the energy
isolating devices in a "safe" or "off" position

25. AFD Lockout/Tagout
• Using the kit on the Rescue, apply the various
lockout devices.
