1. PURPOSE

This DISA (Defense Information Systems Agency, Facilities Engineering Denver) standard establishes guidance for identifying, marking and labeling structures, systems, equipment, and components (SSEC).

2. SCOPE

This standard contains instruction for uniform identification, labeling, and marking of SSEC at DISA locations.

3. DEFINITIONS

‘Shall’ identifies mandatory elements and requirements. ‘Should’ identifies a recommendation that is based on standard industry practice and good business policy. ‘May’ identifies when permission is granted rather than constituted as a requirement.

4. GENERAL REQUIREMENTS

All SSEC shall be labeled in accordance with this standard before being designated operable or in service.

Labeling in areas where hazards exist (i.e., high structures and confined spaces) shall be evaluated against safety requirements. For example, to reduce personnel risk, some SSEC could be labeled as site conditions permit (e.g., shutdown), or when scheduled maintenance is performed.

4.1. LABELING

Labels shall be permanently attached and designed to withstand wear, moisture, erosion and corrosion.

Position labels so they are readily visible and oriented in a horizontal position on a flat surface, where feasible. Labels shall be legible without manipulation by site personnel. Large SSEC shall be labeled in multiple locations, in close proximity to where workers perform their tasks.

Installed labels or tags shall not interfere or alter existing manufacturer’s nameplate or code information.

Labels shall be mounted to preclude accidental removal and located to eliminate any possible confusion as to the item being identified and shall not obscure other items nearby.

Label size shall be based on available lighting and anticipated reading distances. SSEC which require local operation during blackout or reduced visibility conditions shall be marked with reflective or glow-in-the-dark tape. Labels shall not interfere with an operator’s ability to read an instrument, display, or gauge.

4.1.1. Materials

Plastic Labels: Flexible engraving stock (aka Lamicoid or Phenolic) with at least a two-color plastic material to obtain the required color coding combination is the preferred material for permanent systems, equipment, and components (SECs) labels. Characteristics of flexible engraving stock include abrasion, heat, wear, and chemical resistance.

Metal Labels: Metal tags are acceptable for permanent equipment SEC labels. Paints or powder coatings used on these tags shall be environmentally stable, chemically resistant, and wear resistant.

Identification Tape: Commercially available tape products may be used for labeling of common SEC where detailed unique identifiers (UIDs) and other information is not necessary; for example, labels on insulated piping indicating contents and direction of flow.

Machine-Printed Identification Tags: On SEC subject to frequent modification or replacement (for example, power whips from a power distribution unit (PDU) to an IT equipment rack), machine-printed labels are acceptable. These typically print on a flexible form of machine-generated plastic-coated material, which shall be secured to the SEC in such a manner as to protect the labeling information from degradation. Machine-printed identification information shall be indelible, environmentally stable, and chemically resistant.

UNCLASSIFIED – FOR OFFICIAL USE ONLY Page 4 of 9

Unapproved Materials: Materials which can be lost, damaged, rendered unreadable, easily removed, soiled or degraded by operating environment, or which are of a non-permanent nature shall not be used for labeling or identification purposes. This includes (but is not limited to) paper, paper in clear plastic protectors, and direct labeling of SEC with markers. Paint may only be used where specifically identified in this standard, and must be applied using a stencil which meets the font requirements.

4.1.2. Attachment

Adhesives: Adhesives may be used to secure labels or tags to SECs. Adhesives shall securely fasten the label to the SEC without causing degradation to the SEC or the label. The adhesive shall be chemically compatible with the label material, the component material, and the environment. Adhesives shall not be used on stainless steel piping or components.

Wire: Bare wire may be used for attaching labels to SECs where use of adhesives is not practical and there is no risk of the bare wire becoming electrically energized (e.g., valve tags).

Cable Ties: Standard 50 lb cable ties (a.k.a. zip ties, nylon ties, plastic ties, tie wraps) may be used for attaching labels to SECs where use of adhesives is not practical (e.g., valve tags).

Chain: Zinc plated general utility chain may be used for attaching labels to SECs. The type of chain shall be single-jack chain of trade size 20 or 18.

Screws or Rivets: Screws or rivets may be used to secure labels to SECs as long as the attachment does not cause degradation to the SEC or label. Screws shall be metal type, with size, length, diameter, head, pitch, and axis not prescribed, but sufficient to adequately adhere labels. Rivets shall be steel, with type and dimensions not prescribed, but sufficient to adequately adhere labels.

4.1.3. Character Design and Size

Labels shall be formed with upper and lower case letters using simple letter styles. A bold sans serif font, minimum font size 24, is standard for SEC labeling purposes. The maximum standing viewing distance for minimum font sizes is 60 inches (from label to the eye of the standing individual). With this font size, a 3 x 5 inch label is recommended.

Labels not visible from this distance shall use bold sans serif font 28. With this font size, a 4 x 6 inch label is recommended.

Handwritten labels are not permitted.

4.2. COLOR CODING

4.2.1. Color Coding – Pipe and Conduit

Color code mechanical piping and electrical conduit in accordance with the following table:

Table 1 – Compliant Color-Coding for Piping and Conduit Fluid Type / System Pipe/Conduit Color Text Color

Chilled Water Supply Piping Blue White

(2) Near valves or flanges

(3) Adjacent to changes in direction, branches, at any line entry or reentry point

(4) Every 20 to 25 feet on straight runs.

e. Color code conduit and piping or insulation, including when not normally exposed to view, in accordance with one of the following:

(1) For conduit or uninsulated piping, either use paint, or a manufacturer’s color option in accordance with Table 1.

(2) Enclose piping insulation in color-coded plastic (vinyl or PVC) in accordance with Table 1.

Legacy color schemes in use at DISA datacenters are authorized to remain in use. Any and all insulation removed as part of this project shall be replaced using the color coding in accordance with this standard.

4.2.2. Color Coding – SEC Labels

SEC label colors shall provide a high contrast between characters and background to enhance legibility.

Electrical and mechanical SEC labeling shall be color coded in accordance with the following table:

Table 2 – Compliant Color-Coding for SEC Labels SEC Background Color Text Color

“C” Bus Distribution (Essential) & Essential (Emergency Generator) Distribution Black White

Chilled Water Supply Blue White

Chilled Water Return Light Blue White

“D” Bus Distribution (Essential) Gray Black Dual-fed “A” / “B” Bus Distribution (Critical) or Dual-fed “C” / “D” Bus Distribution (Essential) Brown White

4.3. LANGUAGE

Use of SSEC UIDs and descriptions shall be consistent among SSEC labels, equipment lists, drawings, procedures, checklists, and load lists. Checklists, procedures, and installed labels shall use UIDs to describe the name and number nomenclature for the SSEC.

Only use abstract symbols with a commonly accepted meaning for all intended users (e.g. %). Brevity should not be stressed if the results will be unfamiliar to operating personnel. Words on labels should be concise and still convey the intended meaning.
