Health Hazard Evaluation Report No. HETA 81-001-1159, Bookkeepers Tax Service, Inc., Lufkin, Texas

摘要

The requestors also consulted both the Texas State Health Department (TSHD) and OSHA, and both agencies conducted evaluations before NIOSH arrived. NIOSH found no evidence for solvent exposure or for copper fume or unusual copper dust exposure. NIOSH vacuum samples found the highest copper levels in the carpet and air conditioner filter in the NCR portion of the building (140-410 mg/kg), but they were not adjudged to be related to the requestors' symptoms. On the basis of data collected in this study, no evidence of toxic exposures to copper, formaldehyde, carbon monoxide, or solvents was found. While the symptoms reported were not fully explained, NIOSH felt that indoor air quality might be poor, especially in the warmest summer months. Recommendations included improvement of the NCR building ventilation system with fresh make-up air.
