DOT Code: 559.467-010

Industry: plastic-synth.

Measures temperature and humidity in vicinity of machine that transforms liquid polymers, cellulose, or other materials into synthetic fibers by dry spinning (forming) process, to detect deviations from plant standards: Takes humidity readings near spinnerettes through which fibers are extruded into air, using hygrometer or similar humidity gauge. Reads thermometers and temperature-recording charts on machine. Notifies machine operator or other personnel when temperature or humidity conditions are not within specified range, to facilitate equipment adjustments for production of fibers having prescribed characteristics. May compute humidity readings, using wet-bulb and dry-bulb thermometer and standard procedure. May turn valves or move controls to regulate machine or process conditions, according to changes in temperature or humidity.
