Introduction. Occupational exposure to respirable crystalline silica in the coatings industry may occur during, or while working alongside dust-producing operations involving a concrete substrate, while using sand as an abrasive (silica may be present in the abrasive), or as a component of the coating (silica may be an extender used in coatings).
Penn State's Respirable Crystalline Silica (RCS) Program has been established to protect the health of employees and personnel utilizing natural or man-made RCS-containing materials during the course of their work at Penn State properties and facilities, primarily through reducing and controlling airborne dusts which contain RCS.
Crystalline silica is a common mineral found in the earth's crust. Materials like sand, stone, concrete, and mortar contain crystalline silica. It is also used to make products such as glass, pottery, ceramics, bricks, and artificial stone. Respirable crystalline silica – very small particles at

RESPIRABLE CRYSTALLINE SILICA WHAT IS IT? Crystalline silica is a natural substance found in stone, rocks, sand and clay, as well as products like bricks, tiles, concrete and
Crystalline silica (quartz) is a common mineral found in: most rocks, sands, and clays; products such as concrete, mortar, brick, blocks, pavers, tiles, natural and composite stone benchtops
Respirable crystalline silica at work When products containing crystalline silica are used in industrial workplaces, a very fine dust can be produced. This dust (RCS) can pose a risk to workers.
Please describe the procedures to restrict access to work areas, when necessary, to minimize the number of employees exposed to respirable crystalline silica and their level of exposure, including exposures generated by other employers or sole proprieters. Required by 29 CFR 1926.1153 (g)(1)(iv)
The rule is written as two standards: one for construction and the other for general industry and maritime. It reduces the current permissible exposure limits (PEL) of respirable crystalline silica to 50 micrograms per cubic meter (ug/m 3) of air, averaged over an eight-hour shift.
Silica is a natural substance found in most rocks, sand and clay and in products such as bricks and concrete. In the workplace these materials create dust when they are cut, sanded down etc. Some of this dust may be fine enough to reach deep inside the lung, this is known as respirable crystalline silica (RCS) and can cause harm to health.

BY JEROME SPEAR, CSP, CIH * J.E. SPEAR CONSULTING, LP. Silica dust is hazardous when very small (respirable) particles are inhaled. These respirable dust particles can penetrate deep into the lungs and cause disabling and sometimes fatal lung diseases, including silicosis and lung cancer, as well as kidney disease.
Silica—Identifying and managing crystalline silica dust exposure This information guide provides brief guidance on the legislative requirements for identifying and managing respirable crystalline silica (RCS) dust exposure in workplaces. Background Dusts containing respirable silica represent a longstanding health hazard in Queensland's workplaces. This hazard can be found in construction ...

The fine dust is known as respirable crystalline silica (RCS) and is too fine to see with normal lighting. It is commonly called silica or silica dust. It is commonly called silica or silica dust. What is the risk to construction workers?
The OSHA final rule governing respirable crystalline silica calls for employers to monitor air quality and conduct exposure measurements in some situations.
Exposure of workers to respirable crystalline silica is associated with elevated rates of lung cancer. The strongest link between human lung cancer and exposure to respirable crystalline silica has been seen in studies of quarry and granite workers and workers involved in ceramic, pottery, refractory brick, and certain earth industries.
Many persons have heard of the recently revised OSHA standards for respirable crystalline silica, but may not be aware of the relative hazards of exposures to it, where it can be found within ...
Silica (SiO 2) or crystalline silica is a colorless or white crystal 2 commonly found in the earth's crust 3. The most common forms of silica are quartz, cristobalite, and tridymite.

Introduction. Crystalline silica is the name for a group of naturally occurring minerals found in many types of rock. It can be released into the air when the rock or articles made from the rock are crushed, cut, or worked in some other way.
Nearly two-and-a-half years after publishing a rule proposal to reduce the permissible exposure limit for silica, the Occupational Safety and Health Administration (OSHA) released the …
