3. DISCUSSION

Operator aid postings (operator aids) provide information for personnel to use during the

performance of tasks. This information may be in the form of a system drawing, copy of a

procedure, information tag or sheet, curve, chart, or graph. Posted copies of procedures or

portions of procedures that are used as operator aids may be useful when the performance of a

task makes it impractical to refer to a procedure in a manual (e.g., task requires the use of both

hands). Operator aids may help the operator identify problems that might be encountered during

performance of a task, or they may present a simple diagram of equipment, systems, or areas

(e.g., piping diagrams, electrical schematics). Other examples of operator aids include:

A list of approved facility communication terms, abbreviations, and emergency numbers

posted by communication equipment,

A graph of flow versus pump speed for a variable speed pump hanging beside the pump

speed control switch,

A simple diagram of control knobs, valves, and switches for infrequently used equipment,

Specifications for a particular step in a task. (For example, pH minimum and maximum

values and elemental concentrations for disposing of fluids posted by the drain. This one

may be particularly useful since specifications for different fluids can be found in many

different manuals.)

Operator aids must reflect the most current information and they must not conflict with any

procedures or requirements. Using operator aids containing outdated or incorrect information

may cause harm to personnel or damage to the equipment, system, area, or facility. Also, if

operator aids are developed for other than normal operations, (e.g., for temporary systems, for

abnormal system configurations, for emergency situations) it is a good practice to clearly identify

the circumstances under which they apply.

Developing useful operator aids may require intensive research and forethought. The

information presented in the operator aid must be factual, and organized in a manner usable for

all intended users. A thoroughly developed operator aid will ensure that the approver and

reviewers better understand its need and usefulness. During the development process, reviews

by applicable technical personnel may be helpful to ensure clarity.
