6131 Appendix T3

Fall Protection for Work on Low Slope Roofs

 

 

1.0          Purpose

This document identifies fall protection options for work on top of building roofs with fall exposures 4 ft. to a lower level.

2.0          Scope

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.  

3.0          Responsibilities

NOTE:           Management authority may be delegated to a task qualified Jefferson Lab 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.

4.0          Definitions

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 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 Operational Safety Procedure (OSP) Program
