2. Maximum loadings of all components

3. Cable Sag

4. Deflection

5. Deployment of energy absorber

6. Maximum arrest force

2.2 SYSTEM DESCRIPTION

a. System shall not have internal components that cannot be visually inspected.

b. Cable system components shall be of stainless steel construction unless otherwise indicated. Exposed work shall be true to line and level with accurate angles, surfaces and with straight square edges.

c. All primary cable 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 system with supporting [structure][standing seam roofing seams]. Fabricate anchoring devices as recommended by the manufacturer to provide adequate support for intended use.

d. Fabricate Joints in a manner to discourage water accumulation.

Provide weep holes to drain any water, which could accumulate in the exposed joints.

2.3 COMPONENTS

2.3.1 Rooftop Energy Absorbing Anchor Posts

Designed to limit load 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.

Based on compliance with the manufacturer's structural requirements, the posts shall be attached as follows:

SECTION 11 94 11 Page 4

[ Attachment to structure through base plate shall be by means of bolts through roof to structure below or by welding or bolting to roof support structure, as designed by system manufacturer.][Attachment to standing seam roofing seams through base plate shall be by stitching screws, rivets or clamps, as designed by system manufacturer.]

2.3.2 Anchorage Fabrications

Carbon steel construction and designed to withstand the maximum fall arrest forces with a minimum safety factor of two. Steel shall be structural grade with material test certificates for full material traceability. The rooftop anchor posts shall not have internal components that cannot be visually inspected.

2.3.3 Horizontal Lifeline Cable

Stainless Steel AISI 316L 8mm diameter 7x7 or 1x19 wire rope with a minimum breaking strength >37kN.

2.3.4 Swaging

The cable shall be swaged in-line with the anchor point. Each swage is to be proof tested according to the manufacturer's requirements. Cable clamps shall not be utilized for termination of the engineered horizontal lifeline system.

2.3.5 Shock Absorber

When the engineering design dictates the use of load limiting in-line shock absorbers, the shock absorber shall visually display deployment in the event a fall has occurred on the system. In-line shock absorbers are utilized in systems where the loads may exceed the structural ability of the support [structure][standing seam roofing seams]. Shock Absorbers shall not have internal components that cannot be visually inspected.

2.3.6 Cable Trolley

Stainless Steel Z8CND17 04. The cable trolley shall allow for pass-through of intermediate support points without disconnecting from the system.

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

2.3.8 Fasteners

The Fall Arrest Systems shall be attached to the supporting [structure][standing seam roofing seams] with appropriate fasteners. The fasteners shall be designed to support a load on the system of 2 times the maximum design load without failure.

2.4 MATERIALS

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

SECTION 11 94 11 Page 5

b. Primary cable assembly components shall be manufactured from stainless steel. Fabricated supports required for additional support shall be carbon steel with a corrosion resistant finish.

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

These numbers shall be recorded in the system manual as described in Article 1.2 and forwarded to the Contracting Officer upon completion of the project.
