4. GOOD PRACTICES

4.1

Components Requiring Labeling

Facilities should establish written guidelines for labeling components, systems, and

hazards that personnel may be expected to encounter in the course of their work. The

following items should be considered for the labeling program:

C Fluid and gas lines (piping, ventilation

C Cabinets, including internal

ducts, etc.)

components (relays, terminals, etc.)

C Fire protection systems and equipment

C Circuit breakers (4.16kV, 480V,

C Fuse blocks or fuse locations

120VAC/DC, etc.)

C Gauges, meters, and other indicators

C Electrical busses

C Major equipment systems (e.g.,

C Electrical distribution and lighting

emergency generator, heating and air

panels

conditioning system, etc.)

C Emergency equipment (fire alarm

C Motor control centers

stations, eye wash stations, etc.)

C Protective equipment, first aid

C Equipment components (motors,

equipment, safety devices

valves, pumps, etc.)

C Room doors (list major equipment inside

C Equipment subsystems

hazardous or radiation areas)

C Exits, evacuation routes

C Safety hazards and warnings

C Facility location codes (buildings,

C Storage containers, cabinets, storage

columns/rows, floors/elevations)

spaces

C Floor drains

C Test equipment, special tools

4.2

Label Information

A label should provide a concise and meaningful verbal description of the function

(noun name) of an item being identified, and a unique alphanumeric code identifying

the system and component, as shown in Appendix A. Noun names and alphanumeric

codes used on labels should be consistent with those used in all facility procedures,

round sheets, alignment checklists, engineering drawings, and piping and instrument

diagrams. Information on control panel labels should be consistent with the

information on labels attached to the equipment being controlled. Alphanumeric codes

should be developed in a manner that will aid personnel in consistently identifying the

correct component and prevent misidentification. For example, two parallel motor
