• Description:
  The speaker testified that a total weight of particulate from a worker's breathing zone sample would best serve as a screening device for workplace evaluation of exposure to coke oven emissions. It was recommended that an interim exposure level for total particulates be set at 0.5 to 0.7mg/m3. When test results exceed this limit, a benzene soluble fraction should be analyzed, using the existing 0.2mg/m3 standard. Weight was given to findings that coke oven emissions were carcinogenic as were several polynuclear aromatic compounds produced by coking of coal. The recommendations also called for the benzo(a)pyrene (50328) content of the respirable particulate fraction to be analyzed twice yearly as an index for carcinogenic properties of this fraction. While it was acknowledged as difficult to determine which etiologic agent or agents would be most appropriately monitored, as the agents which cause the various types of cancer were unknown, consideration of the screening level based on total particulates, backed up by the benzene soluble standard as it currently existed, was recommended. Specific changes in standards included: extending medical surveillance to include maintenance workers; extending initial examinations to include urinary and skin symptoms such as bloody urine and skin photosensitization; extending pulmonary function tests to include forced expiratory volume in 1 second; and extending skin examinations for premalignant and malignant lesions and evidence of hyperpigmentation.
