- ' Medical Veport oh status of survey of the plant of Lowe Brothers lnc,a Dayton Ohio Lead expo sag's / - ..... -- v ; . Mo clinical studies off the men exposed to lead dust have been made. It is apparent from the survey off the operating conditions at 'the plant' both that a potentially hazardous lead exposureJ;xists, and that efforts have been made by the company to control the hazard. Because of the presence of hazardous concentrations of dust in the air under certain operating conditions, a history, a physical examintion and laboratory studies should be made on each man exposed to such concentrtions*: The frequency of such examinations will depend upon what is found at the time of examination . and the conclusions drawn `from continued observation off the conditions at the plant. Silica and asbestine exposure The X-ray survey is considered adequate evidence of the absence off incapacitating pneumoconiosis among the men. Two men were found with lesions in the chest which require clinical study. If symptoms of pulmonary disease are absent from all"the men, and since we know the general type of exposure to such dusts that exists at the plant, this type off survey indicates that pneumoconiosis is not an uncontrolled hazard at the plant. It is felt that the using off approved dust masks during the addition off ^ * asbestine to the mixers, during the baling operation, and during the unloading and stacking operations will effectively control this hazard. ^ Ethylene dlchloride and benzol exposure , . Prom Inspection of the operation it appears that a hazardous exposure to 'these solvents may exist at times* The. extent of -this exposure should be determined fey adequate sampling' procedures* A clinical study of three nsn exposed to these solvents leads to the conclusion that such men should be carefully followed at frequent intervals* Varnish plant exposures . ' ; Prom Inspection of the operations and sampling of phthalic anhydride, It appears that the possibility of hazardous exposure of varnish Eiakers to acrolein and carbon monoxide should be further investigated, This would require adequate sampling procedures, and cliniqal study of the men if harmful concentrations of these compounds are found. Lacquer plant exposures .. It would appear that adequate air sampling for tile acetates and aromatics would be sufficient to determine hao hazard in this plant. Ho clinical studies of the men beyonu the* periodic studies that should be made on all men in chemical plants, are suggested at present* report by: ,h a. -\'i, nyuer ,.tim h. r . -. ... ; , -- , . . .
