In response to a request from the United Steelworkers of America, Local 7178, an evaluation was made at the Crane Company (SIC-3362), Rogers, Arkansas for possible hazardous working conditions due to employee exposures to lead (7439921), iron-oxide (1309371), zinc- oxide (1314132), silica (7631869) and other dusts. Since engineering changes were due to be made at the facility, this investigation was delayed until these changes were in place. A total of 69 personal breathing zone and general air samples were collected with the following results: iron/iron-oxide concentrations ranged from 0.02 to 0.24 milligrams per cubic meter (mg/m3); zinc/zinc-oxide, 0.16 to 4.48mg/m3; particulate matter, 0.7 to 5.7mg/m3; respirable particulates, 0.4 to 3.0mg/m3; and silica, 2.1 to 5.0mg/m3. Of the 14 personal breathing zone samples taken, 12 exceeded the limits for lead. Problems with skin irritation, cough, tiredness and headache occurred more frequently among core/cleaning workers than other workers, and may have been due to formaldehyde (50000) exposure. A prevalence of dry, cracked hands occurred among mold workers as a result of their use of solvents. The authors conclude that a potential health hazard exists for production area workers from lead and silica exposures, for core/cleaning workers from formaldehyde, and for mold workers from skin contact with solvents. The authors recommend improvements in ventilation, housekeeping, and protective measures. Preplacement and periodic physical examinations, including chest x-rays and pulmonary function tests should be administered to workers exposed to silica.
