SOLVENT REFINED COAL (SRC) PROCESS: HEALTH PROGRAMS RESEARCH & DEVELOPMENT REPORT NO.53 INTERIM REPORT NO.28nVOLUMEⅢ - PILOT PLANT DEVELOPMENT WORK PART 4 - INDUSTRIAL HYGIENE, CLINICAL, AND TOXICOLOGICAL PROGRAMS FOR THE PERIOD JULY 1, 1977 THROUGH JUNE 30, 1978

摘要

This report summarizes the Health Programs under the Solvent Refined Coal (SRC) Process Contract from July 1, 1977 through June 30, 1978. The major areas of activity within the Health Programs are: an industrial hygiene monitoring program, a clinical medical examination program, an educational and personal hygiene program, and a toxicological program. Continuing industrial hygiene monitoring during the period indicated that worker exposures during SRC II operation were generally very similar to the quite low exposures measured during the previous SRC I operation. Significantly lower levels of total suspended particulates and benzene soluble particulates were observed during SRC II operation compared to SRC I operation. The medical examination program continued to indicate the absence of discernible occupationally related changes in employee medical profiles. The employee personal hygiene and education program has continued to be generally successful. Additional visual aids have been incorporated in the educational program.
