J. Arch Flash and Shock Hazard Analysis:

1. The Contractor shall provide Arch Flash and Shock Hazard Warning Signage on all electrical distribution and control equipment in accordance with 2005 NEC Section 110.16, which requires that panel-boards, enclosed circuit breakers, disconnect switches, control panels, motor controls, etc. that are likely to require examination, adjustment, servicing or maintenance while energized, shall be field marked to warn qualified persons of potential arc flash hazards. The markings shall be located so as to be clearly visible to qualified persons before examination, adjustment, servicing, or maintenance of the equipment.

2. This requirement is intended to help reduce the occurrence of serious injury or death due to arcing faults to those working on or near energized electrical equipment. The warning labels are to indicate to a qualified worker who intends to open the equipment for analysis of work that a serious hazard exists and that the worker should follow appropriate work practices and wear appropriate personal protective equipment for the specific hazard.

3. The labels shall include at least the following information: (1) flash hazard boundary; (2) cal/cm2 flash hazard at 18 in. (457.2 mm); (3) PPE Level and PPE required to work on the equipment; (4) shock hazard involved; (5) limited approach boundary; (6) restricted approach boundary; and prohibited approach boundary.

3.2 INSTALLATION

A. Verify identity of each item before installing identification products.

B. Location: Install identification materials and devices at locations for most convenient viewing without interference with operation and maintenance of equipment.

C. Apply identification devices to surfaces that require finish after completing finish work.

D. Self-Adhesive Identification Products: Clean surfaces before application, using materials and methods recommended by manufacturer of identification device.

E. Attach non-adhesive signs and plastic labels with screws and auxiliary hardware appropriate to the location and substrate.

F. System Identification Color Banding for Raceways and Cables: Each color band shall completely encircle cable or conduit. Place adjacent bands of two-color markings in contact, side by side. Locate bands at changes in direction, at penetrations of walls and floors, at 50 ft (15 m) maximum intervals in straight runs, and at 25 ft (7.6 m) maximum intervals in congested areas.

260553-7 260553

G. Color-Coding for Phase Identification, 600-Volt and Less: Use the colors listed below for ungrounded service, feeder, and branch-circuit conductors:

1. Color shall be factory applied or, for sizes larger than No. 10 AWG if authorities having jurisdiction permit, field applied.

2. Colors for 240/120-Volt Circuits:

a. Phase A: Black.

b. Phase B: Red.

c. Phase C: Blue.

3. Field-Applied, Color-Coding Conductor Tape: Apply in half-lapped turns for a minimum distance of 6 in. (150 mm) from terminal points and in boxes where splices or taps are made. Apply last two (2) turns of tape with no tension to prevent possible unwinding.

Locate bands to avoid obscuring factory cable markings.

H. Underground-Line Warning Tape: During backfilling of trenches install continuous underground-line warning tape directly above line at 12 in. (300 mm) below finished grade.
