A professional who tends catalytic reactor and auxiliary equipment that produce monovinylacetylene for use in neoprene rubber manufacture, as directed by mva-reactor operator, head. Respnsibilities include:

• Determines specific gravity of brine solution in drier unit, using hydrometer, and turns valve to circulate brine through saturator to maintain strength at plant standard.
• Weighs prescribed quantities of materials, dumps materials into mixing tanks to prepare brine solution, and opens valve to admit brine to drier as directed.
• Moves controls to start equipment that removes byproduct solution from drier by continuous flotation.
• Draws samples of materials as directed and determines acidity, using standard chemical test equipment and procedure.
• Maintains acidity at specified level in equipment to prevent explosion hazard.
• Drains and flushes saturators, using steam hose, and refills units with calcium chloride to maintain saturator efficiency.
