Fused Silica – Sibelco

Quartz (silica, SiO 2) is the core mineral within the Sibelco group and can be found in a broad number of applications, such as glass, ceramics, filtration, construction, and polymers. Other than grinding and milling high quality quartz (to obtain fused silica) Sibelco has other capabilities to process quartz:

Respirable Crystalline Silica Dust Exposure During Concrete

More than 100 000 workers encounter high risk silica exposure through construction and mining operations (NIOSH, 1991). Exposure to crystalline silica can result in both respiratory and non-respiratory health effects.Of the respiratory effects, silicosis is one of the most documented occupational diseases . Every year, >250 workers in the USA

Silica Dust Safety in Construction - OSHAcademy free online

As you know by now, cutting, drilling, and grinding without using engineering controls can cause exposure to respirable silica to reach much higher than the OSHA PEL. The level of respiratory protection needed depends on the employee’s silica exposure, which varies due to:

Health and Safety CN Scabbling or grinding

Construction: Silica CN1 Scabbling or grinding 3 On-tool extraction is a type of local exhaust ventilation (LEV). For LEV, a user manual or log book is helpful in setting out the frequency of checking, maintenance or parts replacement. Contact the manufacturer/supplier if you do not have this information.

Crystalline silica and silicosis | Safe Work Australia

Silica dust is generated in workplace mechanical processes such as crushing, cutting, drilling, grinding, sawing or polishing of natural stone or man-made products that contain silica. Some dust particles can be so small that they are not visible; these are commonly referred to as respirable particles.

Silica Dust Prevention: Construction Dust Control Methods for

There are numerous job tasks and functions throughout the construction industry that are notorious for producing massive amounts of dust. Typically these jobs involve grinding, sawing, drilling, and chiseling. For masons, the danger comes from operating on stone and concrete materials such as brick, asphalt, and mortar that contain concentrated amounts of crystalline silica. When these

OSHA's Silica Dust Standards: First Construction, Now

OSHA’s silica dust Permissible Exposure Limit (PEL) for construction and general industry is 50 micrograms per cubic meter averaged over 8 hours. While this number probably means little to most people, consider this: the new PEL is just 20% of the old silica PEL.

Dust containing crystalline silica in construction work

Exposure to crystalline silica can occur during common construction and demolition tasks when working with concrete, bricks, mortar, tiles, stone or other masonry. If employees regularly dry cut, grind, crush, drill, sweep or demolish these materials without engineering controls in place, it is likely that the exposure standard will be exceeded.

The Dusty Dangers of Concrete Cutting & Grinding | Industrial

Concrete cutting and concrete grinding are very dusty jobs in the construction industry, both posing a serious health risk to masons. Masonry blocks, bricks, and concrete slabs contain concentrated amounts of crystalline silica. When these materials are dry-cut they release silica containing dust into the workers’ breathing zone. Regular exposure to this hazardous dust can lead to the
