Abstract
Respirable crystalline silica dust is a respiratory hazard commonly found in the construction industry. When concrete of other masonry is disturbed by either sawing, grinding or hammering, dust controls such as water application or local exhaust should be used to reduce or eliminate the high concentrations of dust in a short time, if not properly controlled, working in enclosed of partially enclosed areas which are not ventilated increases exposures. A number of National Institute for Occupational Safety and Health (NIOSH) field studies have found a need for improved control of respirable crystalline silica during sawing and drilling of masonry material. For example, NIOSH obtained a measurement of 14.2 mg/m3 of respirable crystalline silica dust, while a plumber used a handheld masonry saw on a concrete floor, without dust control, inside an unventilated office building that was being renovated.
