A professional who signals hot-car operator to dump coke onto wharf.
* Quenches hot spots in dumped coke, using water hose, to prevent burning of conveyor belt.
* Pushes and pulls lever gates to control flow of coke from wharf onto conveyor belt.
* Shovels spilled coke onto conveyor.
Industry:Professional careers
A professional who tends series of burners, located in channel-process burner buildings (hot houses), that produce carbon black by contact of gas flame with collecting channels, from which deposited carbon is scraped. Respnsibilities include:
* Turns valves to regulate flow of gas or mixture of gas and oil to burners to produce flames that deposit carbon black on channels (flat surfaces).
* Turns handwheel to bring channels into contact with flame.
* Opens and closes doors at sides and ends of burner building to regulate draft and compensate for changes in atmospheric conditions, air-fuel mixtures, draft, and fuel consumption.
* Observes, through building ports, accumulation of carbon black, automatic scraping of accumulation from channel, and flow of carbon black through conveyors to detect malfunction of burners and scrapers and to verify production rate.
Industry:Professional careers
A professional who tends equipment that sublimates (refines by vaporization) crude salicylic acid derived from coal tar. Respnsibilities include:
* Weighs specified amount of salicylic acid and dumps it onto conveyor leading to sublimation unit.
* Starts fans that circulate heated air in unit to promote vaporization of salicylic acid.
* Starts pump to draw salicylic-acid vapor through filters into condenser tanks where salicylic acid recrystallizes.
* Keeps daily production records.
Industry:Professional careers
A professional who tends equipment in furnace-process plant that produces carbon black by partial combustion of crude oil, natural gas, or mixture of both. Respnsibilities include:
* Starts individual units, such as reactors (furnaces), quenchers, precipitators, cyclones (grit collectors), pumps, compressors, and conveyors.
* Turns valves to regulate flow of water in quencher, feed rate of fuel and air, and movement of accumulated carbon black through equipment, as directed by plant operator, furnace process.
* Observes gauges and meters to verify specified temperature, pressure, and flow rates of materials.
* Opens inspection ports and observes flow of product through conveyors to detect jamming.

A professional who controls kettles to boil oil to specified viscosity for use in making coated textile material. Respnsibilities include:
* Pumps oil into kettle.
* Lights burner with torch and monitors burners and temperature gauges to ensure that specified oil temperature is maintained.
* Adds chemicals to facilitate drying when coating is applied to cloth, and stirs mixture, using paddle.
* Draws sample of oil and feels oil with fingers to estimate viscosity.
* Marks oil temperature and time of reading on chart for laboratory use.
* Pumps oil to and from kettle through water-cooled coils to maintain specified temperature and viscosity.
* Collects sample of oil for laboratory viscosity verification.
* Pumps oil to storage tank.
* Records amount of oil used and amount remaining in tanks.
Industry:Professional careers
A professional who operates pit furnace to bake carbon-block anodes (electrodes) to remove volatile matter and increase electrical conductivity. Respnsibilities include:
* Lights burner and adjusts fuel and water valves, manifold damper, and head covers to regulate temperature in furnace.
* Observes gauges and records water and fuel pressures.
* Measures flue and pit temperatures, using optical pyrometer.
* Inspects and maintains pumps, motors, fans, gas scrubber system, and pipelines.
* Signals carbon-furnace-operator helper to prepare alternate pits for furnace changeover to maintain baking schedule.
