Set up, operate, or tend continuous flow or vat-type equipment; filter presses; shaker screens; centrifuges; condenser tubes; precipitating, fermenting, or evaporating tanks; scrubbing towers; or batch stills. These machines extract, sort, or separate liquids, gases, or solids from other materials to recover a refined product. Includes dairy processing equipment operators.
- Clean and sterilize tanks, screens, inflow pipes, production areas, and equipment, using hoses, brushes, scrapers, or chemical solutions.
- Measure or weigh materials to be refined, mixed, transferred, stored, or otherwise processed.
- Collect samples of materials or products for laboratory analysis.
- Dump, pour, or load specified amounts of refined or unrefined materials into equipment or containers for further processing or storage.
- Examine samples visually or by hand to verify qualities such as clarity, cleanliness, consistency, dryness, and texture.
- Monitor material flow and instruments such as temperature and pressure gauges, indicators, and meters, in order to ensure optimal processing conditions.
- Remove clogs, defects, and impurities from machines, tanks, conveyors, screens, or other processing equipment.
- Set or adjust machine controls to regulate conditions such as material flow, temperature, and pressure.
- Start agitators, shakers, conveyors, pumps, or centrifuge machines, then turn valves or move controls to admit, drain, separate, filter, clarify, mix, or transfer materials.
- Assemble fittings, valves, bowls, plates, disks, impeller shafts, and other parts to equipment in order to prepare equipment for operation.
- Communicate processing instructions to other workers.
- Connect pipes between vats and processing equipment.
- Inspect machines and equipment for hazards, operating efficiency, malfunctions, wear, and leaks.
- Install and maintain or repair hoses, pumps, filters, or screens in order to maintain processing equipment, using hand tools.
- Maintain logs of instrument readings, test results, and shift production, and send production information to computer databases.
- Pack bottles into cartons or crates, using machines.
- Remove full bags or containers from discharge outlets, and replace them with empty ones.
- Test samples to determine viscosity, acidity, specific gravity, or degree of concentration, using test equipment such as viscometers, pH meters, and hydrometers.
- Turn valves to pump sterilizing solutions and rinsewater through pipes and equipment, and to spray vats with atomizers.
- Realistic - Realistic occupations frequently involve work activities that include practical, hands-on problems and solutions. They often deal with plants, animals, and real-world materials like wood, tools, and machinery. Many of the occupations require working outside, and do not involve a lot of paperwork or working closely with others.
- Investigative - Investigative occupations frequently involve working with ideas, and require an extensive amount of thinking. These occupations can involve searching for facts and figuring out problems mentally.
- Conventional - Conventional occupations frequently involve following set procedures and routines. These occupations can include working with data and details more than with ideas. Usually there is a clear line of authority to follow.
- Education - These occupations usually require a high school diploma.
- Training - Employees in these occupations need anywhere from a few months to one year of working with experienced employees. A recognized apprenticeship program may be associated with these occupations.
- Experience - Some previous work-related skill, knowledge, or experience is usually needed. For example, a teller would benefit from experience working directly with the public.
- Computers and Electronics - Knowledge of circuit boards, processors, chips, electronic equipment, and computer hardware and software, including applications and programming.
- Mathematics - Knowledge of arithmetic, algebra, geometry, calculus, statistics, and their applications.
- Education and Training - Knowledge of principles and methods for curriculum and training design, teaching and instruction for individuals and groups, and the measurement of training effects.
- English Language - Knowledge of the structure and content of the English language including the meaning and spelling of words, rules of composition, and grammar.
- Public Safety and Security - Knowledge of relevant equipment, policies, procedures, and strategies to promote effective local, state, or national security operations for the protection of people, data, property, and institutions.
- Production and Processing - Knowledge of raw materials, production processes, quality control, costs, and other techniques for maximizing the effective manufacture and distribution of goods.
- Chemistry - Knowledge of the chemical composition, structure, and properties of substances and of the chemical processes and transformations that they undergo. This includes uses of chemicals and their interactions, danger signs, production techniques, and disposal methods.
- Mechanical - Knowledge of machines and tools, including their designs, uses, repair, and maintenance.
- Conveyor Operators and Tenders
- Cutting, Punching, and Press Machine Setters, Operators, and Tenders, Metal and Plastic
- Extruding and Forming Machine Setters, Operators, and Tenders, Synthetic and Glass Fibers
- Gas Compressor and Gas Pumping Station Operators
- Plating and Coating Machine Setters, Operators, and Tenders, Metal and Plastic
- Printing Machine Operators
