EXPLANATION

A fundamental concept in the use of maintenance contractor supplied conven-tional suspended access equipment such as bosun’s chair, single work cage or platform is that there must be two inde-pendent means of support for each worker using the equipment.

The first means of support is the access equipment itself tied back to an anchor.

The second is usually provided by a sep-arate fall arrest system consisting of a:

• full body harness;

• lanyard (with shock absorber);

• mechanical rope grabbing device;

• lifeline;

• lifeline anchor.

In addition, anchors, which are used for tie-backs or for securing lifelines, are also an effective, practical means for directly securing a bosun’s chair with descent control equipment, the most popular method of window cleaning today (direct rigging).

Bosun’s chair is the equipment of choice among window cleaners. Pro-Bel safety anchors (see photo at right) are used to secure chair and separate lifeline.

All Buildings Require Roof Anchors Extract From ANSI/IWCA I-14.1 Window Cleaning Safety Standard:

4.1.1 All buildings where window clean-

ing is performed that employ suspended equipment shall be equipped with roof anchorages or other approved devices which will provide for the safe use of the equipment in conformance with the pro-visions of this Standard.

DESCRIPTION

Note: Pro-Bel tie-back/lifeline anchors and direct rigging anchors are the same and are used interchangeably.

Safety Anchor Types There are literally dozens of Pro-Bel safety anchor products available. Each has been engineered to satisfy a particu-lar job requirement. They can be catego-rized as follows:

PB and PBE Series Wall Anchors PB wall anchors are fabricated using a patented stainless steel U-bar which is detachable for ease of replacement, con-crete forming and waterproofing. PBE anchors are a more economical alterna-tive to PB anchors and are used when flashing or waterproofing is not a consid-eration.

PBE Series Roof Anchors PBE Series anchors have a non-detach-able stainless steel U-bar and are flashed using a spun aluminum flashing sealed at the top with a heat-shrink rubber collar flashing.

PB Series Roof Anchors PB Series anchors, somewhat more expensive than PBE Series anchors, are fabricated using a patented stainless steel U-bar and stainless steel cap flash-ing which is detachable for ease of replacement.

USE

ANSI/IWCA I-14.1 (3.9 Anchorages) states that “Building owners and window cleaning contractors shall not allow sus-pended work to be performed unless it has determined that the building has pro-vided, identified and certified anchorages complying with Section 9 or 10 for: inde-pendent safety lines; tie-backs for outrig-gers, parapet clamps and cornice hooks;

primary support anchorages for powered and manual boatswain’s chairs; primary support anchorages for rope descent systems; horizontal (rope) lines or life-lines; and wherever else required.” Pro-Bel roof anchor set into concrete pier

(PB70).

Pro-Bel PB type wall anchor in concrete wall of rooftop mechanical room.

Pro-Bel wall anchor recessed in box flash-ing (PB71S).

FEATURES

All corrosion resistant materials;

anchor components are stainless steel and/or hot dipped galvanized steel.

Standards conformance; all anchors comply with OSHA and ASME/ANSI/ IWCA safety requirements for window cleaning, and various materials stan-dards.

Installation flexibility; Pro-Bel safety anchors are suited to a broad range of building structures, including concrete, structural steel or precast panels.

Securement methods include cast-in-place, through bolts, bolt around, weld-ing, or chemical epoxy fastening.

Engineer certified; OSHA and ANSI/ IWCA I-14.1 requires that safety anchor-ing devices be designed by or under the direction of a registered professional engineer experienced in such design.

Pro-Bel safety anchors meet this criteria and anchor performance is based on data derived from testing and/or engi-neering calculations. Anchors have been tested to ensure fracture or detachment does not occur with the application of a 5,000 lb (22.2 kN) load in any direction.

Compatible with roofing; Due to strin-gent OSHA anchor placement require-ments i.e. in line with the point of sus-pension and free fall distance, anchors, for the most part, must necessarily be placed on the roof. An important consid-eration in the design of Pro-Bel anchor products is the need to maintain the long term watertight integrity of the building.

Pro-Bel products are designed with a full understanding of reliable flashing/sealing techniques to satisfy any roof condition.

Where anchors are located in water-proofed areas of a roof, a pier is normal-ly provided to elevate the anchor above the waterproofing. In the case of metal pier anchors, the pier is supplied with the anchor and a prefabricated flashing to suit roof type as required. With concrete pier anchors, the pier must be formed, the anchor cast in, and the flashing fabri-cated at the job site.

Sole responsibility; Pro-Bel provides complete fall protection products/sys-tems from concept to the supply and installation of same, including annual inspection.

Specific liability insurance; all Pro-Bel davit installations automatically carry $5,000,000.00 + coverage against prod-uct/ system failure (over 5000 projects successfully completed to date).

MATERIALS/FABRICATION

(as applicable)

U-bar, anchor bolts, detachable caps:

Type 304 stainless steel with yield strength of 42 Ksi (290 MPa) or mild steel to ASTM A36, Type 350W with yield strength of 43 Ksi (297 MPa), hot dipped galvanized to ASTM A123/A123M-2002.

Hollow steel section (HSS) piers: gal-vanized mild steel as above with yield strength of 50 Ksi (345 MPa), with or without urethane foam insulation.

Plate and all other sections: galva-nized mild steel as above with yield strength of 43 Ksi (297 MPa).

Seamless spun aluminum flashing (for steel pier anchors): Type 6061-T6 alloy to ASTM B221-2000 with deck flange flashed in using felt plies to NRCA or CRCA recommendations or roofing membrane manufacturer’s instructions, as applicable.

Top of anchor sealing (for steel pier anchors): torch applied heat-shrink rub-ber collar flashing or detachable U-bar complete with stainless steel watertight cap.

Bolts, nuts and washers: Type 304 stainless steel or galvanized steel to

ASTM A325.

Note: Illustrated on the next few pages are only some of the many model varia-tions of anchor products available.

Anchors can be engineered to satisfy vir-tually any access requirement.

Pro-Bel wall anchor bolted to steel beam supporting rooftop AC chiller unit.

Minimum anchors; OSHA and ANSI/ IWCA I-14.1 requires that equipment tie-backs be “installed at right angles to the face of the building whenever possible”.

This requirement, can result in an unnecessary number of installed anchors. Pro-Bel has developed anchor placement chart data to help designers locate anchors to suit tie-back and life-line requirements. This data ensures compliance with OSHA fall protection criteria while reducing the number of anchors (and roof penetrations) required.

Note Re: Alternative Finish to Galvanizing. For all anchor bases and supports, Pro-Bel offer a superior protective coating _ Protex _ in lieu of galvanizing if desired. Pro-Bel Protex is a 3/32” (2.4 mm) thickness, black colored, two component spray on, flexible 100% solids ther-moplastic (TPU) polyurethane/polyurea system. Protex provides exceptional impact and abrasion resistance and is factory applied via high pressure impingement mix polyurethane dispensing equipment. See Pro-Bel Protex Technical Data Sheet # R-2 for complete information.

TESTING*

Testing of Pro-Bel wall and roof anchors involve a variety of both shop and on-site test methods including static, dynamic and destructive procedures. All testing is car-ried out by independent testing agencies or under the direction of a professional engineer in accordance with recognized standards.

Anchors secured using epoxy adhesive are tested to 5000 lbs (22.2 kN) to ensure against failure. The photos on this page provide an overview of Pro-Bel test pro-cedures.

* Test data available upon request.

The static load test in the above photo, which applies force using a heavy duty cable come-along, was conducted to show that Pro-Bel wall and roof anchors comply with stan-dards that require the anchors be capable of resisting without fracture and/or pull-out a force of 5000 lbs (22.2 kN). A similar test is performed on-site to verify strength of epoxy adhesive roof anchors.

Pro-Bel wall anchors secured to structural concrete using epoxy adhesive are load tested on-site using a hydraulic pull tester to verify strength and anchor bolt integrity.

Photo shows 8’-0” (2440 mm) high apparatus used for shock (drop) testing of Pro-Bel safe-ty U-Bar anchors. A 220 lb. (100 kg) weight was connected to the anchor using a steel test lanyard and dropped a distance of 4’- 0” (1220 mm). A series of anchors employing different securements were tested and peak forces up to 18,522 lbs (8400 kg) were gener-ated without fracture to any part of the anchors.

A series of Pro-Bel safety U-Bar anchors were tested to determine their ultimate strength (destructive testing). The force used to break the test specimens was pro-vided by a hydraulic system, a hooking mechanism, and support structure. The highest pressure recorded just before a specimen was broken in this series of tests measured 32,445 lbs (4500 psi * 7.210 in2).

PRO-BEL ROOFTOP SUPPORTS

Application Recommended for use in new construction or retrofit applica-tions where it is necessary or desirable to conceal the anchor when not in use i.e. terrace, balcony or roof deck locations. Pro- Bel flip-up and recessed anchors are designed to suit all roof conditions including cast-in-place and weldment applications.

Application Ideal for use in new construction for exposed concrete bal-conies where it is desirable to directly rig a bosun’s chair over a balcony rail. If the rail cannot accommodate the loads, outrigger beams may be employed for exterior maintenance using a ground rigged platform. The embed anchor (con-nector) is removed and capped flush when not in use.

Pro-Bel galvanized steel pipe support complete with U-Bar safety anchor.

Pro-Bel also manufactures a complementary line of rooftop supports for pipes, satel-lite dishes, catwalks, cellular towers, antenna, guy wire securement, air conditioning units and similar equipment. These supports can be supplied as stand alone items or combined with U-bar safety anchors and are secured and flashed in using the same reliable methods employed for Pro-Bel anchors.

FOR BOSUN’S CHAIR

DESIGN CONSIDERATIONS

Roof Space: Conventional (non-perma-nent) outrigger beams employing coun-terweights, when used with descent con-trolled bosun’s chair, single work cage or platforms are normally supported to clear a low non-structural parapet wall. Con-ventional outrigger beams are typically 12’-0” to 15’-0” (3658 mm to 4572 mm) long and have a reach of 3’-0” (915 mm) or less beyond the roof edge. They require sufficient space on the roof to accommodate the inboard portion of the beam and the tie-back.

Parapet Strength: If the parapet wall is structurally sufficient, a parapet wall clamp may be secured to the wall for the suspension of access equipment.

Also, a bosun’s chair can be directly secured to a safety anchor. This is known as direct rigging. The chair is rigged directly to wall or roof anchors in line with the point of suspension, and the primary synthetic rope suspension lines are nor-mally protected at the parapet using con-tractor supplied carpet or other anti-abra-sion protection devices.

When the parapet is not capable of sup-porting the applied loads, primary sus-pension support equipment such as out-rigger beam dollys or davits must be con-sidered. See Pro-Bel Outrigger Beam Systems or Davit Systems literature.

Parapet Height: Anchors can be installed in parapet walls provided walls meet the following criteria:

Wall is 42” (1067 mm) minimum guardrail height;

Wall has been engineered to take the applied loads.

Structural loads: Anchors are designed to a maximum fall arresting force of typi-cally 1800 lbs (8.0 kN) when wearing a body harness with a safety factor of 2 without any permanent deformation and to 5000 lbs (22.24 kN) against fracture or detachment.

Free Design Service: The selection of window cleaning equipment is a perfor-mance oriented and highly specialized field requiring an in-depth knowledge of Rigging Methods, Safety and OSHA Standards/State Codes. Pro-Bel provides a free design service to ensure that Pro- Bel systems are properly specified.

Pro-Bel portable outrigger with beam dolly is ideal for clearing non-structural parapet.

Note separate pier- type safety anchors for securing lifelines. See Pro-Bel Outrigger Beam Systems literature.

This photo shows a Pro-Bel roof anchor installation. Anchors are welded to struc-tural steel before a horizontal lifeline cable system is installed to provide fall protec-tion on this arched roof.

Pro-Bel portable aluminum ground rigged davit arms are ideal for clearing non-struc-tural parapets or reaching out past build-ing face obstructions. See Pro-Bel Davit Systems literature.

1.

2.

Location of Lifeline Anchors: The location of lifeline anchors relative to tie-back anchors must be such that a work-er can neither fall more than 6’-0” (1.8 m), nor contact any lower level (OSHA 1910.66, Subpart F and ANSI/IWCA I-14.1, section 9.2.2 (g) 2). See Layout data on page A-12.

ANCHOR LAYOUT PROCEDURE

1. Review the Pro-Bel System & Equipment Introduction literature (pages G-6 to G- 18). This data provides an overview of the various equipment options used to clean windows or perform other suspended build-ing maintenance.

2. Identify all roof levels. Mark window loca-tions on other areas requiring access on the architectural roof plan drawing(s).

3. Examine building section drawings to assess construction of parapet wall, mechanical room wall and roof assembly or other building elements as necessary.

4. Examine roof structural drawings for possi-ble anchorage locations.

5. Examine building elevations or other draw-ings to identify any setbacks, recesses or other unusual features.

6. Review the Design Considerations on page A-10 to assist in making a "rigging" deci-sion.

7. If it has been determined that "rigging" is suited to using anchors only, for both the support of primary suspension equipment and lifelines, refer to Anchor Spacing Chart at right on page A-12.

Note: Primary suspension equipment refers to conventional, maintenance contractor supplied equipment i.e. bosun's chair, transportable out-rigger beams, single work cage, temporary platform and parapet wall clamps.

ANCHOR PLACEMENT

1. After determining what areas of the build-ing face will need to be accessed for main-tenance, anchor locations can now be cho-sen.

2. Anchors are located on the roof of the building and are generally secured to any or all of the following acceptable vertical or horizontal elements: mechanical room curb walls; parapet walls minimum 42" (1067

mm) high; roof mounted structural ele-ments e.g. rooftop equipment structural support beams or columns, and similar structures; roof decks (to concrete slab, precast deck, structural steel, and similar structures); finished roof top terraces.

3. Ideally locations for Pro-Bel safety anchors are in direct line with the anticipated "drops" and are suited to both bosun's chair and suspended platform. A "drop" for a chair is typically a 6'-0" (1830 mm) wide area, and 20'-0" to 28'-0" (7000 mm to 8535 mm) for a platform. Two anchors are required for bosun's chair (1 primary and 1 lifeline) and 4 anchors are required for a platform (2 primary and 2 lifeline).

4. Lifeline anchors and primary tie-back anchors for transportable outrigger beams and parapet wall clamps should be located in line with the point of suspension (per-pendicular) whenever practical, but should not be offset more than 10'-0" (3084 mm) measured horizontally from running at a right angle to the building face at the point of suspension. The angle created by the offset distance should not exceed 25º. See anchor spacing chart data on page A-12.

5. If a bosun's chair or similar single point suspension equipment is used with the pri-mary support lines directly attached to anchors (direct rigging), the horizontal por-tion of the descent line (that portion of the support from the anchor to the roof edge) should be in a plane at right angles to the face of the building at the "drop". This guideline will ensure that slide distance and swing action in the event of a fall will be reduced to a reasonably safe minimum thereby lessening the potential for worker collision injury, while allowing for self-recovery.

Essentially, OSHA 1910.66, Subpart F and ANSI/IWCA I-14.1, section 9.2.2 (g) 2 requires personal fall arrest systems be rigged such that an employee can neither free fall more than 6'-0" (1.8 m), nor contact any lower level. Any anchor placement sce-nario should reflect this requirement.

ANCHOR PLACEMENT (continued)

6. Locate the very first roof anchor, which should be a primary suspension or tie-back anchor. If the parapet wall is less than 42" (1067 mm) guardrail height, this anchor should be a minimum of 6'-0" (1830 mm) distance from the parapet so that the work-er can tie off whenever the worker has to step within 6'-0" (1830 mm) of an unguard-ed edge. If the parapet is minimum 42" (1067 mm) high, the anchor can be located any distance inside the parapet.

7. The second and subsequent primary sus-pension or tie-back anchors can now be located as per item 3.

8. After primary anchors have been located, lifeline anchors can now be located relative to the primary anchors using the anchor spacing chart data at right.

9. Anchor spacing must be adjusted, of course, to circumvent any obstruction.

Note: Pro-Bel tie-back/lifeline anchors and direct rigging anchors are the same and are used interchangeably.

When rigging primary lines, tie-back lines and lifelines for a bosun’s chair, single work cage or platform, there are many scenarios having an influence on whether lines are anchored in line with or offset from the point of suspension. Ultimately, the object is to place the anchors in a man-ner that will suit chair and platform loca-tions within the variable work zones while ensuring that the OSHA maximum free fall distance of 6’-0” (1.8 m) is not exceeded, in the event of a worker falling.

Recognizing this, Pro-Bel designers employ a 25O angle placement criteria for locating anchors. This criteria will ensure that the primary support lines and secondary lifelines are rigged within 15O of the point of suspension in accordance with the ANSI/IWCA I-14.1 Window Cleaning Safety Standard.

EXAMPLE INSTALLATION _ RETROFIT ROOF ANCHORRELATED DATA

For general data relating to all Pro-Bel products and services e.g. codes, instal-lation, warranty, etc., refer to the Pro-Bel System & Equipment Introduction litera-ture (pages G-2 to G-32). For product data relating to other fall protection sys-tems and primary suspension equip-ment, see other Pro-Bel literature.

OTHER USES

Generally, Pro-Bel window cleaning/sus-pended maintenance anchor systems are economical or practical for all new or retrofit buildings 3 stories and higher where windows or building facades are accessed from the roof.

In addition to window cleaning applica-tions, Pro-Bel safety anchor systems are recommended for work such as:

• construction, restoration, cleaning, sandblasting, caulking, or pointing;

• fall protection for ladder work using full body harness and lanyard; and

• interior or exterior industrial applica-tions wherever maintenance personnel are exposed to falls from elevation.

Pro-Bel safety anchor systems are com-patible with all types of suspended main-tenance equipment and can be used interchangeably for either tying off sus-pended equipment or fall protection life-lines.

BUILDING OWNER ASSURANCE

There is a shared responsibility between the building owner and the window clean-ing/suspended maintenance contractor/ employer . OSHA and ANSI/IWCA I-14.1 acknowledges that the building owner is the controlling influence and must assure the contractor that the system has been installed in accordance with engineered drawings, test data (when required), and equipment specifications. The building owner shall provide written assurance that the installation has been annually inspected and maintained to ensure that all equipment is safe and operating as required.

Refer to Pro-Bel “Digest for Building Owners, Property Managers, and General Contractors” literature for more detailed information.

AVAILABILITY & COST

Pro-Bel window cleaning/suspended maintenance safety systems are distrib-uted throughout the United States, Canada and internationally.

Budget pricing is provided on a project-to-project basis for both materials and installation, or materials only. See “Tech-nical Consultation” at right.

FREE DESIGN SERVICE

The selection of window cleaning equipment is a performance oriented and highly specialized area. Also the issues of fall protection and fall arrest are serious concerns with OSHA inspection authorities. Interpreting the myriad OSHA standards, including the separate requirements of various states, and proposed changes, is a daunting task at best.

Each building is different, requiring an individual technical approach and a time commitment beyond the scope of most professional offices. Even with a high degree of knowledge and the best of intentions, the planning process can go askew. It is for these reasons that Pro-Bel provides archi-tects and engineers with a FREE DESIGN SERVICE, and to ensure that Pro-Bel Window Cleaning/Suspended Maintenance Systems are properly specified and installed.

TECHNICAL CONSULTATION

Pro-Bel Enterprises Limited provides a complete technical consultation service, available to architects, consultants, engi-neers, contractors, and building owners.

Without obligation, Pro-Bel will provide interested parties with a proposed win-dow cleaning/suspended maintenance design concept to OSHA requirements, including anchor and equipment loca-tions, securement, roofing details and specifications.

Simply provide the following information:

• roof plans (architectural & structural);

• building elevations;

• typical floor plans

• section drawings showing parapet walls or roof edge condition and mechanical room walls; and

• any other drawings pertinent to window cleaning/suspended maintenance re-quirements.

Pro-Bel will review drawings and provide one or more concepts as required with respect to equipment, tie-back methods and similar options.

In addition, Pro-Bel Enterprises Limited will provide budget pricing for window cleaning/suspended maintenance sys-tems contingent upon design acceptance between Pro-Bel and architect/owner for the proposed project.

DESCRIPTION

Davits, used singularly or in pairs, pro-vide an efficient and practical means for suspending bosun’s chairs, single work cages or platforms.

Davits are commonly used on multi-level buildings and where it is necessary to clear non-structural parapets, sloped glazing, and decorative cornice moldings.

Davits provide greater flexibility in roof rigged applications i.e. clearing high parapets or storing platform on roof.

Available in aluminum or steel, with alu-minum being the most popular due to weight and ease of handling.

Steel masts are primarily used for long reach davit arms complete with rein-forced aluminum booms. These heavy long reach arms are often recommended to be permanently left in place.

Davit systems are very popular on build-ings with various terrace levels. Davit bases can be recessed below the pavers if an inverted roofing system is used. The davit base can be concealed with a paver cap.

Davit bases are completely installed around the perimeter of the roof top.
