Environmental and breathing zone samples were analyzed for acetone (67641), carbon-tetrachloride (56235), 2-heptanone (110430), epichlorohydrin (106898), benzene (71432), carbon-disulfide (75150), acetonitrile (75058), toluene (108883), and ether (60297) at the Robert Taft Center (SIC-7391), Cincinnati, Ohio in June, July, and September 1977. The survey was requested by the safety officer of NIOSH in compliance with the requirement that all federal agencies have an annual industrial hygiene survey. Noise level measurements were taken at various locations. Relative humidity and air flow measurements were also taken. All airborne concentrations measured were below the relevant OSHA standards. No noise levels in excess of the OSHA standard were observed. Relative humidity determinations were within the range considered to be comfortable. Ventilation measurements taken in the laboratories showed many of the hood faces to have inadequate air flow. Sections using radioactive materials were found to practice poor housekeeping techniques and did not keep proper records of the disposal of radioactive substances. Employees were not exposed to toxic concentrations of the sampled compounds. Recommendations include better housekeeping practices for radioisotopes, improved hood ventilation to increase air flow, and maintenance of an inventory of hazardous substances in each laboratory.
