Abstract
Environmental noise was studied in the weaving department of Portec, Incorporated in Paducah, Kentucky, on February 27 to March 1, 1978, to determine employee exposure to potentially excessive noise levels. The evaluation was requested by the production superintendent on behalf of about 45 employees. The employees were monitored with a dosimeter, and a noise classifier monitored the looms. Nine of the 13 loom operators monitored were potentially exposed to noise levels exceeding the OSHA standard of 90 decibels relative to the A-weighted scale (dBA) for an 8 hour exposure. Sound pressure measurement at loom platforms ranged from 93 to 101dBA. Personal dosimetry measurements ranged from 0.4 to 2.5 times the permissible limit. Earplugs provided to workers had sufficient attenuation capabilities based on a comparison of their mean attenuation to the octave band sound pressure levels generated by the looms. The investigators conclude that noise in the weaving department potentially could exceed permissible limits. They recommend reducing employee exposure to noise by engineering controls, using ear protectors until effective engineering controls are implemented and audiometric testing of personnel assigned to high noise areas. They also recommend environmental sampling to evaluate cotton dust and asbestos (1332214) exposure, if the weaving room ceiling is composed of asbestos.
