Title Acute expanded perlite exposure with persistent reactive airway dysfunction syndrome
Bibliographic information Jan. 2010, Vol.48, No.1, p.119-122. 14 ref.

Abstract After an accidental release of expanded perlite powder in a factory in Taiwan, 24 exposed workers were followed for more than six months. Three developed persisting respiratory symptoms with positive provocation tests that were compatible with a reactive airway dysfunction syndrome. During an experimental simulation of the accident, expanded perlite was shown to be very dusty, with airborne concentrations greatly exceeding current exposure limits. A review of literature showed that while exposure of expanded perlite below current permissible levels may be generally safe, precautionary protection of short-term exposure to high concentrations is warranted.
