Full article: Reported exposures to respirable crystalline silica
Introduction. Silica consists of silicon dioxide (SiO 2) and occurs in crystalline and non-crystalline (amorphous) forms (NIOSH Citation 2002).Crystalline silica, also referred to as "free" silica, is characterized by SiO 2 molecules oriented in a fixed pattern, in contrast to amorphous silica, which is defined by a random molecular arrangement …
Leached Silica Fabrics
Temperature resistant, but not as durable as MaxSil®Tex silica fabrics, leached silica fabrics work well in the light-duty application, one-time use or as welding cloth curtains. Leached silica fabric is manufactured from glass fabric then leached to provide a minimum 95% Silica content product.
Respirable crystalline silica
Consider the following information when determining how to manage respirable crystalline silica (RCS) exposures in the workplace. Harmful effects of silica. Silica or silicon dioxide (SiO2) is a very common mineral. It occurs in many products including sandstone, concrete, brick and engineered / manufactured stone.
