An historical mortality study was carried out on a cohort of 1074 white women, 130 black women, and 494 black men employed at a continuous filament fibreglass manufacturing plant for a minimum of one year between 1951 and 1991. Compared with national mortality, there were no significant excesses or deficits in mortality by cause, including cancer causes, among white women, with the exception of an increase in motor-vehicle accidents. Similarly, no significant excesses were found among black men; standardized mortality ratios for heart diseases and for all cancers combined were below one.

In a mortality study of current and former workers at a continuous filament fibreglass manufacturing plant, standardized mortality ratios (SMRs) for white men were near or below unity for all causes of death and for all cancer mortality compared with national and local standards. The slight elevation in the SMR for lung cancer among these men was not significant. A case-control study based on 45 lung cancer cases showed that the lung cancer odds ratio among white men exposed to respirable glass fibres was below unity, as were those for exposure to asbestos, respirable silica, and other substances investigated. None of these exposures suggests an increase in lung cancer risk for this population.
