Appendix T3: Fall
Protection for Work on Low Slope Roofs
|
||
|
|
|||
This document identifies fall protection options for
work on top of building roofs with fall exposures ≥ 4 ft. to a lower level.
This document applies to lab staff
only involved in servicing/maintenance work activities governed by OSHA’s
general industry standard 29 CFR 1910 Subpart D, as invoked by the Department
of Energy via 10 CFR 851.23(a)(3).
This
appendix is written in coordination with ES&H Manual Chapter 6131 Fall
Protection Systems.
Note: Management
authority may be delegated to a task-qualified TJNAF employee at the discretion
of the responsible manager.
3.1
Employees
Using Fall Protection Systems
· Maintain current training on use of
active fall protection systems, and on work control documents.
·
Collect
active fall protection system components from the Material Handling Manager (MHM).
·
Conduct
a pre-use inspection of active fall protection system equipment.
·
Wear
the appropriate active fall protection equipment for the job.
·
Do
not use any equipment which fails a pre-use inspection or is past due for a
formal inspection. Remove from service
and notify supervision.
·
Transfer
any active fall protection system component that fails a pre-use inspection, is
past due for a formal inspection, or has arrested a fall, to the MHM.
· Review,
sign, and abide by hazard mitigation methods outlined in work control
documents.
·
When
establishing a designated area for fall protection atop a low-slope roof, erect
warning lines prior to commencing work, and work within the designated area.
3.2
Supervision
·
Ensure that work control documents are completed and
approved prior to start of work, and workers have been
trained.
· Ensure
walking/working surfaces can support maximum loads.
· Ensure
anchorages for active fall protection systems have been evaluated and approved
by a qualified person.
· Ensure
that proper fall protection is being employed by workers.
· Ensure
all active fall protection system components are available for formal
inspection by the MHM.
· Ensure
active fall protection equipment is stored appropriately to prevent damage from
operations, the environment, or other work activity.
·
When used on top of low-slope roofs,
ensure warning lines meet strength and location criteria.
3.3
Material Handling Manager (MHM)
·
Conduct
formal inspections of all active fall protection system components in
accordance with manufacturer’s recommendations, or annually, whichever is more
frequent.
·
Purchase
and issue active fall protection system equipment.
·
Maintain
inspection records of active fall protection system components.
·
Dispose
of defective or otherwise unusable active fall protection system components.
·
Conduct
harness fitting for affected personnel and certify individuals have
demonstrated proper donning/doffing of active fall protection system gear.
·
Approve use of crane hooks as anchor points.
3.4
ESH Fall
Protection Subject
Matter Expert (SME)
·
Establish
and maintain training programs for active fall protection systems.
·
Conduct
pre-work walk-downs of jobsite prior approval of work control documents.
·
Provide
oversight on the implementation of fall protection systems.
·
Approve use of crane hooks as anchor points.
3.5
Anyone at
Jefferson Lab
· If the
integrity or load-bearing capacity of a walking/working surface is questioned, suspend
work activity, secure the area, and notify supervision.
· If the
integrity of passive fall protection systems is questioned, or observed to be
deficient, suspend work activity, secure the area, and notify supervision.
4.1
Low Slope Roof
A
building roof which has a slope less than or equal to a ratio of 4 in 12
(vertical to horizontal)
4.2
Work Activity Descriptions
4.2.1
Infrequent – task is performed only on occasion,
on an as-needed basis (such as responding to equipment failure), or at sporadic
or irregular intervals. Examples of infrequent tasks include the following:
·
Annual
maintenance or servicing of equipment
·
Monthly
or quarterly replacement of batteries or HVAC filters
·
Responding
to equipment outage or breakdown
|
Note:
Work activities which are not considered infrequent include
those performed ·
daily,
on a regular routine basis ·
as
a primary or routine part of a job ·
repeatedly,
at various locations during a work shift |
4.2.2
Temporary – characteristics of a temporary
tasks include the following:
·
Duration
is short or brief, such as those which take less than 2 hours to complete
·
Can
be completed at one time and does not require repeatedly climbing up on or
returning to the roof.
·
Simple
tasks which do not require significant equipment, personnel, or other resources
to accomplish
·
Short-term
scheduled maintenance or minor repair activities
4.3
Warning Line – a rope, wire, tape, or chain
established to identify the boundaries of designated areas on low-slope roofs.
Warning lines shall meet the following criteria:
·
Minimum
breaking strength of 200 lbs.
·
Erected
such that it is between 34 in. and 39 in. above the surface of the roof,
including sag.
·
Clearly
visible from a distance of at least 25 ft. from any location within the
designated area.
·
Supported
in such a manner that pulling on one section of the warning line will not
result in the take-up of slack in adjacent sections, causing the line to drop
to less than 34 in.
5.0
Process
Steps/Requirements
5.1
Work Performed Less Than 6 ft. From
Unprotected Edge
When work is performed less than 6 ft. from the
nearest unprotected roof edge, employ one or more of the following fall protection
systems:
·
Guardrail
System (see ES&H Manual Chapter 6131
Appendix T1 Passive Fall Protection Systems)
·
Fall
Restraint System (see ES&H Manual Chapter 6131 Appendix
T2 Active Fall Protection Systems). A work control document (OSP, TOSP, or Fall
Protection Permit) is required.
·
Fall
Arrest System (see ES&H Manual Chapter 6131 Appendix
T2 Active Fall Protection Systems). A work control document (OSP, TOSP, or Fall
Protection Permit) is required.
5.2
Work Performed At Least 6 ft., but
Less Than 15 ft., From Unprotected Edge
When work is performed at a distance at least 6 ft.,
but less than 15 ft., from the nearest unprotected roof edge, employ one or
more of the following fall protection systems:
·
Any
of the fall protection systems identified in Section 5.1.
·
If
work activities are both infrequent and temporary, a designated
area may be established within which all work must be performed. Designated
areas shall be delineated by installation of warning lines located as close to
the work area as tasks permit, but no less than 6 ft. from the nearest
unprotected edge. Use of a designated area with warning lines requires development and approval of either an OSP or TOSP.
5.3
Work Performed 15 ft. or More From
Unprotected Edge
When work is performed at a distance at least 15 ft.
from the nearest unprotected roof edge, employ one or more of the following
fall protection systems:
·
Any
of the fall protection systems identified in Section 5.1.
·
Use
of a designated area whose boundaries are identified by warning lines located as
close to the work area as tasks permit, but no less than 15 ft. from the
nearest unprotected edge. Use of a designated area with warning lines requires development and approval of either an OSP or TOSP
·
If
work activities are both infrequent and temporary, an OSP or TOSP may be developed which
prohibits employees from approaching to within 15 ft. of the nearest
unprotected edge. See ES&H Manual Chapter 3310
