2.3 SYSTEM DESIGN

A. The Fall Arrest Systems shall be designed to fully protect the user at all times while in the area of potential fall hazard. The Fall Arrest Systems shall be designed for TWO (2) simultaneous users.

B. Deceleration Device: Provide appropriate length lanyards that meet or exceed applicable standards of ANSI Z 359.1 and OSHA 1926.104.

C. Harnesses: Provide full body harnesses with single back D-ring that meet or exceed applicable standards of ANSI Z 359.1 and OSHA 1926.104

2.4 SYSTEM DESCRIPTION

A. Horizontal Lifeline Cable: Marine grade stainless steel wire rope with a minimum breaking strength of 10,000 pounds.

B. Force Limiting Anchorage Posts: Designed to limit load to 10kN in the event of a fall and absorb the energy integrally. The body of the anchorage is to deploy in the event of a fall pulling the fixings in shear and preventing damage to the roof system. Weather proof construction and designed for attachment to all major composite, built-up on site, standing seam and single ply membrane roofing. Attached by means of stitching screws, spilt clamps and toggle bolts with no need for fixing to purlins or structural steel.

C. Swaging: The cable shall be swaged in-line with the anchor point and have a slip indicator.

D. Shock Absorber: Load limiting in-line shock absorber to 3,000 pounds for multi-span systems and 4,500 pounds for single span systems. The shock absorber shall visually display deployment in the event a load such as a fall has occurred on the system.

E. End Anchors: 316 stainless steel end anchors with minimum breaking strength of 10,000 pounds.

F. Transfastener/Trolley: 316 stainless steel with a minimum tensile load of 3600 pounds. The transfastener shall allow for easy pass-thru of support points without disconnecting from the system.

G. Tension Indicator: The system shall include a tension indicator that will allow the user to physically inspect that the correct cable tension is achieved.

H. Fasteners: The Fall Arrest Systems shall be attached to the supporting structure with appropriate fasteners. The fasteners shall be designed to support a load on the system of 2 times the maximum design load without failure.

I. Other Components: Corner Assemblies, Turnbuckles and other components shall be 316 stainless steel.

J. System components shall be of same material unless otherwise indicated. Exposed work shall be true to line and level with accurate angles, surfaces and with straight square edges. Coordinate anchorage sys-tem with supporting structure. Fabricate anchoring devices as recommended by the manufacturer to pro-vide adequate support for intended use.

K. Fabricate Joints in a manner to discourage water accumulation. Provide weep holes to drain any water, which could accumulate in the exposed joints.

2.5 MATERIALS

A. All materials shall be new, and completed Fall Protection System shall be the product of one manufacturer or the manufacture’s authorized installer regularly engaged in the design and production of such equipment.

B. Fall Arrest Systems and Components: All system connectors, cables and bolts shall be manufactured from stainless steel: ASTM A 666, Type 316. All connectors shall comply with OSHA regulation 1926.502. Fabricated supports required for additional support shall be carbon steel with a corrosion resistant finish.

C. Material Control: All system components shall contain serial numbers, permanently stamped or engraved, identifying the specific job and system they are used for.
