PART 2 PRODUCTS

2.1 SYSTEM DESCRIPTION

Design, furnish, install, and certify a complete and useable permanent fall protection system, inclusive of all components, appurtenances, fasteners, end stops, carriages, and equipment necessary for safety of maintenance workers.

Submit horizontal life line and anchorage connector systems for approval by the designer of record and the installation public works group's cognizant architect or designated fall protection expert. The chosen fall protection system must be compatible with the Base Exterior Architectural Plan, low-maintenance, designed for service in harsh coastal conditions, and compliant with ANSI/ASSP Z359 requirements. The following proprietary systems would meet government requirements, but other options may be proposed by the contractor, subject to final approval by the government:

1) 3M Capital Safety Roofsafe Rail System

2) Miller ShockFusion Horizontal Lifeline Roof System

3) Kee Safety KeeLine Engineered Lifeline Solution

2.1.1 Design Requirements

a. Design must be performed, signed, and sealed by a Professional Engineer from the manufacturer experienced in the design of horizontal lifeline fall arrest systems. Submit qualifications of engineer.

b. Design must provide for access from the roof hatch (where provided) to the roof ridge, allowing for continuous worker tie off to reach the ridge line. For buildings without a roof hatch, design must provide for access from the roof eave (at an acceptable location) to the roof ridge, allowing continous worker tie off to reach the ridge line.

D-rings are acceptable for ascent and decent parallel to standing seams, or propose alternative method.

c. Low profile and architecturally pleasing systems are preferred, and will be evaluated higher than more obtrusive designs.

d. Concealed fastners are preferred.

2.1.2 Performance Requirements

a. System must be able to accomodate three (3) users at a time.

b. All fall protection anchorages must be designed for a minimum 3,100 lb nominal live load capacity. Anchorages, including any supporting structure, must be designed to allow future replacement of the horizontal lifeline system or anchorage connectors regardless of the required capacity of the chosen horizontal lifeline system or anchorage connectors. Anchorages that support two or more independent horizontal life line spans at a single point must be designed for the combined load effects of the horizontal life line systems in accordance with

ANSI/ASSP Z359.6.

2.2 FINISHES

a. Choice of finishes in powder coated or anodized aluminum alloy are preferred.

b. Color must comply with the MCBCL Base Exterior Architectural Plan (BEAP) and the USG Architect. Submit color samples for approval.

2.3 TESTS, INSPECTIONS, AND VERIFICATIONS

After fall protection system is installed, the manufacturer's authorized representative shall inspect and operate the system and make any final adjustments. The manufacturer's authorized representative shall issue a certificate attesting to the system's design and installation, and formally submit to the USG.

PART 3 EXECUTION

3.1 INSTALLATION

Fall protection system shall be installed under the direction of manufacturer's authorized trained personnel.

3.2 INSPECTION

The manufacturer's authorized representative shall inspect and operate the system and make any final adjustments.

3.3 CLOSEOUT ACTIVITIES

3.3.1 Demonstration

The manufacturer's authorized representative shall issue a certificate attesting to the system's design and installation, and formally submit to the USG.

3.3.2 Training

Train designated US Government personnel on-site regarding proper use of system.
