Title: Health-hazard evaluation report HETA 90-232-2138, Schulte Corporation, Cincinnati, Ohio

In response to a confidential request from employees of the Schulte Corporation (SIC-3496), Cincinnati, Ohio, an evaluation was undertaken of complaints of chest tightness, itching, metallic taste in the mouth, and discharge of black dust from the noses of workers in the machine shop of the facility. The facility was involved in the manufacturing and shipping of epoxy coated steel wire shelving. Total dust samples taken in the breathing zone of the workers ranged from 0.49 to 4.78mg/cu m, well below the permissible limits. Respirable dust samples ranged from 0.05 to 0.43mg/cu m. Exposures to nitrogen oxides were well below acceptable limits. Aldehydes were not detected in samples evaluating exposure to two resistance welders. The NIOSH ceiling level of 0.1 part per million for ozone (10028156) was exceeded near welders. Six workers interviewed reported symptoms including black nasal discharge, headaches, sore throat, cough, hoarseness of voice, metallic taste and chest tightness. There was a potential ergonomic problem due to repetitive wrist motion. The authors conclude that a potential hazard from ozone exposure existed. The authors recommend measures to reduce exposures and development of a program for the prevention of cumulative trauma.
