These materials
were produced by the Division of Safety, Florida Department of Labor
and Employment Services, as part of a special OSHA program to reduce
work-related deaths in construction in California, Florida, and Texas.
Because Florida's funding for the program - CARE, or Construction
Accident Reduction Emphasis - ended in June 2000, the materials will
not be updated. The materials should be reviewed yearly for any needed
changes.
- AND -
There is no OSHA lockout/tagout standard for construction. But the
information provided here is good practice. |

PROCEDURES
PREPARATION FOR
LOCKOUT OR TAGOUT
Employees who are required to utilize the lockout/tagout procedure (see
attachment
#A-1) must be knowledgeable of the different energy sources and the proper
sequence
of shutting off or disconnecting energy means.
The four types of energy sources are:
- Electrical (most
common form)
- Hydraulic or
pneumatic
- Fluids and gases
- Mechanical
More than one energy
source can be utilized on some equipment and the PROPER
procedure must be followed in order to identify energy sources and lockout/tagout
accordingly. See Attachment D for specific procedure format.
ELECTRICAL
A. Shut off power
at machine and disconnect.
B. Disconnecting means must be locked or tagged.
C. Press start button to see that correct systems are locked out.
D. All controls must be returned to their safest position.
E. Points to remember:
- If a machine
or piece of equipment contains capacitors, they must be drained of
stored energy.
- Possible disconnecting
means include the power cord, power panels (look for primary and secondary
voltage), breakers, the operators station, motor circuit, relays,
limit switches, electrical interlocks.
NOTE:
- Some equipment
may have a motor isolating shut-off and a control isolating shutoff.
- If the electrical
energy is disconnected by simply unplugging the power cord, the cord
must be kept under the control of the authorized employee or the plug
end of the cord must be locked out or tagged out.
HYDRAULIC/PNEUMATIC
A. Shut off all energy
sources (pumps and compressors). If the pumps and compressors supply energy
to more than one piece of equipment, lockout or tagout the valve supplying
energy to this piece of equipment.
B. Stored pressure from hydraulic/pneumatic lines shall be drained/bled
when release of stored energy could cause injury to employees.
C. Make sure controls are returned to their safest position (off, stop,
standby, inch, jog, etc.).
FLUIDS AND GASES
A. Identify the type
of fluid or gas and the proper
B. Close valves to prevent flow, lockout/tagout.
C. Determine the isolating device, close, and lockout or tagout.
D. Drain and bleed lines to zero energy state.
NOTE: Some systems may have electrically
controlled valves; if so, they must be
shut off, locked or tagged out.
E. Check for zero energy state at the equipment.
MECHANICAL ENERGY
(Gravity activation, or stored in springs, etc)
A. Block out or use
die ram safety chain.
B. Lockout or tagout safety device.
C. Shut off, lockout or tagout electrical system.
D. Check for zero energy state.
E. Return controls to safest position.
RELEASE FROM LOCKOUT/TAGOUT
A. Inspection - -
Make certain the work is completed and inventory tools and equipment used.
B. Clean-up - - Remove all towels, rags, work-aids, etc.
C. Replace guards - - Replace all guards possible. Sometimes a particular
guard may have to be left off until the start sequence is over due to
possible adjustments, however, all other guards should be put back into
place.
D. Check controls - - All controls should be in their safest position.
E. The work area shall be checked to ensure that all employees have been
safely positioned or removed and notified that the lockout/tagout devices
are being removed.
F. Remove locks/tags - - Remove only your lock or tag.
PROCEDURE INVOLVING
MORE THAN ONE PERSON
When servicing and/or maintenance is performed by more than one person,
each authorized employee shall place his own lock or tag on the energy
isolating source. This shall be done by utilizing a multiple lock scissors
clamp if the equipment is capable of being locked out. If the equipment
cannot be locked out, then each authorized employee must place his tag
on the equipment.
PROCEDURE FOR
THE REMOVAL OF AN AUTHORIZED EMPLOYEES
LOCKOUT/TAGOUT BY THE COMPANY
Each location must develop written procedures under the above heading
that
complies with 1910.147(e)(3) that can be utilized at that location. Your
procedures
should include the following:
- Verification
by employer that the authorized employee who applied the device is not
in the facility.
- Make reasonable
efforts to advise the employee that his device has been removed. (This
can be done when he returns to the facility).
- Ensure that
the authorized employee has this knowledge before he resumes work at
the facility.
PROCEDURES FOR
SHIFT OR PERSONNEL CHANGES
Each facility must develop their own written procedures based on
their need and
capabilities. However, your procedure must specify how you will ensure
the
continuity of lockout or tagout protection during that time. See 1910.147(e)(4).
PROCEDURES FOR
OUTSIDE PERSONNEL/CONTRACTORS
Outside personnel/contractors
shall be advised that the company has and enforces the use of lockout/tagout
procedures. They will be informed of the use of locks and tags and notified
about the prohibition relating to attempts to restart or re-energize machines
or equipment that are locked out or tagged out.
The company will obtain information from the outside personnel/contractor
about their lockout/tagout procedures and advise affected employees of
this information.
The outside personnel/contractor will be required to sign a certification
form (see attachment C). If outside personnel/contractor has previously
signed a certification that is on file, their is no need to have them
sign a new certification.
TRAINING AND COMMUNICATION:
Each authorized employee who will be utilizing the lockout/tagout procedure
will be trained in the recognition of applicable hazardous energy sources,
type and magnitude of energy available in the work place, and the methods
and means necessary for energy isolation and control.
Each affected employee (all employees other than authorized employees
utilizing the lockout/tagout procedure) shall be instructed in the purpose
and use of the lockout/tagout procedure and the prohibition relating to
attempts to restart or re-energize machines or equipment which are locked
out or tagged out.
Training will be certified using attachment #A-2 (Authorized personnel)
or #A-3 (Affected Personnel). The certification will be retained in the
employee's personnel file.
PROCEDURES FOR
PERIODIC INSPECTION
