Health Hazard Evaluation Report No. TA-80-103-800, Social Security Administration/Health and Human Services, Santa Rosa, California

摘要

Worker exposures to mineral-spirits (8032324) from photocopying machines were surveyed on an unspecified data at the Santa Rosa Social Security Office (SIC-9441) in Santa Rosa, California. The evaluation was requested by the Design and Engineering Branch of the Department of Health and Human Services. General area and personal air samples were collected along with bulk samples of the dispersant and toner. Concentrations of straight chain aliphatic hydrocarbons in the air samples ranged from 27.8 to 87.9 milligrams per cubic meter (mg/cu m), well below respective OSHA standards for C6, C7, and C8 aliphatic hydrocarbons of 1,800, 2,000 and 2,350mg/cu m, and below the evaluation criteria of 350mg/cu m. Bulk samples contained a mixture of C6 to C12 compounds. The author concludes that no hazardous exposures to mineral spirits existed at the time of the survey. Recommendations include regular servicing and the maintenance of photocopying machines, and provision of adequate ventilation.
