Title Occupational exposure to alkoxysilanes in a fibreglass manufacturing plant
Bibliographic information Nov. 1999, Vol.72, No.8, p.539-545. 30 ref.
Abstract To assess the exposure of workers to alkoxysilanes and to determine the main route of exposure during the manufacture of fibreglass, samples were taken from workers and their environment. The silane concentrations in the air samples were below the detection limit of the analytical methods used. The mean dermal exposure to 3-glycidoxypropyltrimethoxysilane was analysed from cellulose patch samples as well as in handwash samples. The results showed that the workers were clearly exposed to silanes. The main route of potential exposure was through the skin, especially the hands, which emphasized the importance of wearing appropriate protective gloves. According to patch sampling, on average two thirds of the cases of total dermal exposure were caused by exposure of the forearm, as indicated by the amounts of silanes analysed in the forearm patches. Since almost every worker wore protective gloves, the main cause of exposure to silanes was from the wearing short-sleeved T-shirts which did not provide any protection to the arms.
