Occupations | 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).

| Tends equipment units or semiautomatic system that processes chemical substances into industrial or consumer products, such as detergents, emulsifiers, salts, bleaching agents, acids, and synthetic resins: Dumps specified amounts of solid materials into heating vessels or blending tanks; and turns valves to feed liquid and gaseous materials through equipment units, or sets controls in specified sequence on control panel to start automatic feed. Turns valves or moves controls to maintain system at specified temperature, pressure, and vacuum levels. Observes chemical reactions; monitors gauges, signals, and recorders; and receives notification from control laboratory, supervisor, or other workers to make specified operating adjustments. Draws samples of products for laboratory analysis. Maintains log of gauge readings and shift production. May perform chemical tests on product to ensure conformance with specifications, using standard test equipment, materials, and procedure. May be designated according to substance processed as Low-Chloride Soda Operator (chemical); Salt-Plant Operator (chemical); Sodium-Methylate Operator (chemical); equipment tended as Styrene-Dehydration-Reactor Operator (chemical); Tower Operator (chemical) II; or reaction produced as Emulsification Operator (oils & grease); Precipitation Equipment Tender (chemical).

| Controls nuclear reactor that produces steam for generation of electric power and coordinates operation of auxiliary equipment: Adjusts controls, under supervision, to start and shut down reactor and to regulate flux level, reactor period, coolant temperature, and rate of flow, control rod positions, and other control elements that affect power level within reactor, following standard instructions and prescribed practices. Dispatches orders and instructions to plant personnel through radiotelephone or intercommunication system to coordinate operation of such auxiliary equipment as pumps, compressors, switchgears, and water-treatment systems. May assist in preparing, transferring, loading, and unloading nuclear fuel elements. May be required to hold Nuclear Reactor Operator's license. May be required to hold Radiotelephone Operator's license. May control dual purpose reactors that produce plutonium and steam. May control operation of auxiliary equipment, such as turbines and generators [SWITCHBOARD OPERATOR (utilities); TURBINE OPERATOR (utilities)]. (references) | |
| Operates equipment to control chemical reaction of soda ash and milk of lime to make caustic soda: Opens valves and starts pumps to fill dissolving tank with specified amounts of soda ash and milk of lime. Starts mixer in tank to agitate materials and dissolve solids. Draws sample of mixture from tank and measures its gravity with hydrometer. Opens water valve to dilute mixture and obtain specified concentrations according to type of product. Turns valves and rheostats to adjust feeding of solution to reactor tank. Periodically takes samples of reacting liquor and titrates samples with normal acid to determine concentration of caustic soda being formed. Conducts similar tests and titrations to determine salt content and concentration of various liquors. Clears stopped pipelines and repairs equipment, using handtools. (references) | |
