Silica exposure is associated with increased risk of

Rock drilling and stone crushing are associated with substantial levels of silica exposure, 13, 14 and are also work tasks that are rather easily recalled, whereas self reported exposure to stone dust in general may be more vague. We therefore considered rock drillers and stone crushers as belonging to a category with higher levels of silica

Self‐reported disease symptoms of stone quarry workers

Protecting workers from silica dust exposure can be achieved through various exposure control measures. 5 This can be achieved through eliminating tasks that expose workers to silica dust, substituting crystalline silica materials with non‐crystalline silica materials, using engineering controls such as water spray or local exhaust

OSHA’s silica rule explained • Aggregate Research

OSHA’s silica rule outlined earlier this year brings new resposibilities for the quarry and construction industries. Danielle L Kitson at law firm Littler Mendelson explains the requirements.. Earlier this year, the Occupational Safety and Health Administration (OSHA) published its long-awaited final rule setting new workplace permissible exposure limits (PELs) for respirable crystalline silica.

OCCUPATIONAL EXPOSURE DETERMINATION TO SILICA DUST

Introduction: Dust is one of the significant factors which cause occupational respiratory diseases among workers. Objective: The main purpose of this study was to determine the dust concentration, its silica percentage and comparison with standard. Method: This cross-sectional study was carried out at one of iron-stone ores in Southern Khorasan province.

due to exposure of silica dust. Stone crusher impact zones are covered with Granite, Silica sand and Morrum. The various crushing operations involved in stone crushing e.g. blasting, manual cutting, crushing and transportation emit fugitive stone dust. These fine aerosol of stone dust causes health problems among the stone crusher workers.

Silica Dust WorkSafe ACT

Manufacturers and importers of products containing silica need to determine if workers can be exposed to the respirable fraction of airborne dust when working with these products e.g. when cutting. Where exposure to silica can occur, products must be labelled and safety data sheets provided in accordance with the Work Health and Safety
