4. What is covered?


Servicing and maintenance
Normal production operations where:
 Employees
by-pass guard(s)
 Employees place any part of their body in a
hazardous area
When you are training it is important to cover the
relationship between Subpart O-Machine Guarding
and Lockout Tagout!!

5. What is not covered?
Construction, agriculture, and maritime
 Normal production operations (subpart O)
 Cord-and-plug under the control of
employee (written procedure still required)
 Exposure to electrical conductors (subpart
S and electrical safety-related work
practices)


6. Locked Out?????????

7. Energy types
Electrical
 Mechanical
 Hydraulic
 Pneumatic
 Chemical
 Thermal
 Other


8. Lockout vs. Tagout

If capable of being locked out:
 Prefer
lockout
 Tags allowed, if employer can demonstrate
FULL EMPLOYEE PROTECTION

Machine Modifications
 If
you alter a machine you must make the
machine capable of accepting a lock.

9. Full employee protection?

locks
 Full compliance with all tagout provisions
in 29 CFR 1910.147
 Additional means when necessary (e.g.
removal of a valve handle)


10. Definitions

 Installing


12. Lockout/tagout requirements

 Specific procedural steps
 Specific testing requirements


15. Documentation exceptions:
Machine has no potential for stored
energy
 Machine has a single energy source
 Isolation of that source will completely deenergize
 Machine is isolated and locked out during
maintenance


16. Documentation exceptions
(cont.)
A single lockout device will achieve
locked-out condition
 Lockout device under exclusive control of
employee
 Maintenance does not create hazard to
others
 No previous accidents involving
unexpected energization on this
equipment


17. Energy control procedure








Notification of employees
Preparation for shutdown

Lockout/tagout device application
Stored energy
Verification of isolation
Release from lockout/tagout

18. Equipment Specific Procedures

19. Lockout procedure – Step 1

NOTIFICATION OF EMPLOYEES
 Before
controls are applied, and before they
are removed

20. Lockout procedure – Step 2

PREPARATION FOR SHUTDOWN
 Knowledge
of the type and magnitude of
energy and methods to control energy

21. Lockout procedure – Step 3

MACHINE OR EQUIPMENT SHUTDOWN
 Orderly
shutdown to avoid increased hazard

22. Lockout procedure – Step 4

MACHINE OR EQUIPMENT ISOLATION
 All
energy isolation devices located and
operated to isolate machine

23. Line breaking:
Means the intentional opening of a pipe,
line, or duct that is or has been carrying
flammable, corrosive, or toxic material, an
inert gas, or any fluid at a volume,
pressure, or temperature capable of
causing injury

24. Line blanking or blinding:
Means the absolute closure of a pipe, line,
or duct by fastening of a solid plate that
completely covers the bore and that is
capable of withstanding the maximum
pressure of the pipe, line, or duct with no
leakage beyond the plate.

25. Double block and bleed:
Means the closure of a line, duct, or pipe by
closing and locking or tagging two in-line
valves and by opening and locking or
tagging a drain or vent valve in the line
between the two closed valves.

26. Lockout procedure – Step 5

LOCKOUT OR TAGOUT DEVICE
APPLICATION
 Affixed
by authorized employee holding
energy isolating device in the safe or off
position

28. Lockout procedure – Step 6
