1.2 SYSTEM DESCRIPTION

A. This project has two fall arrest systems. The systems consist of two (2) or three (3) rails total:

1. Fuel Bay: approximately 42 feet in length

2. Main Bay: approximately 65 feet in length, total, with a break to accommodate the fixed crane system.

Systems will be installed in the Vehicle Maintenance Building 3 (Attachment 3) located at Quonset Air National Guard Base (QANGB), North Kingstown, RI 02852.

Each rail must have 2 trolleys, lanyards, and other components for support of 2 people. Personnel may be located on work stands or on the vehicle.

Refer to additional information and photographs provided in Attachment 1.

B. Engineering Analysis Design Requirements

1. Fall protection systems must be designed by a Professional Engineer experienced in the design of fall protection systems, registered and licensed in the State of Rhode Island.

2. Fall protection systems must be designed for use above vehicles with 2 concurrent users;

users must be able to walk uninterrupted the entire length of each system without having to unhitch from the system to pass through intermediate support points.

3. The overall system and all components must comply with ANSI/ASSP Z359.2, ANSI/ASSP Z359.3, ANSI/ASSP Z359.6, ANSI/ASSP Z359.7, ANSI/ASSP Z359.11, ANSI/ASSP Z359.12, ANSI/ASSP Z359.13, ANSI/ASSP Z359.14, ANSI/ASSP Z359.15, and ANSI/ASSP Z359.18.

4. Dynamic and dead load reactions must be generated for all intermediate and end supports of the fall protection system.

5. Design fall protection systems to safely resist the dynamically applied loads while maintaining a safety factor of two against failure.

6. Design of fall protection systems must be based on the understanding that the underlying structural steel supports are provided as part of the bay and are adequate to support the imposed loads. Fall Protection loads must be furnished to the hangar structural designer.

7. The Design Engineer must prepare a fall clearance analysis verifying adequate fall distance to safely stop the worker in the event of a fall.

8. Rails must be designed for 2 workers falling at a time with full body harnesses and shock-absorbing lifelines, with a maximum arresting force of 900 pounds per worker.

9. The Design Engineer must coordinate the Fall Protection System with the mechanical and electrical systems, lighting, piping, and structural supports of the hangar.
