TITLE(s): CHEMICAL OPERATOR III (chemical) alternate titles: reactor operator
Controls equipment units or system that processes chemical substances into specified industrial or
consumer products, according to knowledge of operating procedures, chemical reactions, laboratory
test results, and correlation of process instrumentation: Reads plant specifications to ascertain
product, ingredients, and prescribed modifications of plant procedures. Starts automatic feed of
solid or semisolid materials through equipment units, such as heating vessels and mixing tanks; or
dumps preweighed ingredients into tanks, hoppers, or onto conveyor. Moves controls to regulate feed
of liquids and gases through equipment in specified timing and sequence, or starts automatic feed.
Sets up and adjusts indicating and controlling devices, such as gas analyzers, recording
calorimeters, and radiographic detecting or gauging instruments to facilitate simultaneous analysis
and control of process conditions. Observes gauges, signals, and recording instruments, turns
valves, and moves controls to regulate temperatures, pressures, and flow of steam, coolant, and
chemical constituents through system to effect prescribed reaction within critical limits, according
to knowledge of equipment and process. Draws samples of product at specified stages of synthesis and
performs litmus, titration, refractometer, gas-analyses, or other standard tests to determine if
reaction is proceeding efficiently and in conformity with plant standards. Observes color or
consistency of product through sight glasses, and correlates observations with test results,
laboratory analyses, and instrument readings to facilitate regulation of process and production of
standardized product. Maintains log of gauge readings, shift production, and equipment malfunctions.
May patrol area to inspect equipment for leaks and hazards and to record gauge readings. May direct
activities of other workers assisting in control or verification of process. May be designated
according to equipment or system controlled as Caustic-Purification Operator (chemical);
Gas-Generator Operator (chemical); Lanolin-Plant Operator (pharmaceut.); Sulfonator Operator
(chemical); or according to product produced as Alkylation Operator (chemical; petrol. refin.);
Ethylene-Oxide Panelboard Operator (chemical); Polymer Operator (plastic-synth.); Sodium-Chlorite
Operator (chemical).
