Like a floodlight with a bad electrical connection, the issue of silica has been flickering for major attention for the past 2 or 3 years. Although an occupational hazard and known killer since the 1960s, silica is again gaining popularity with the trial lawyers and, as a result, is having somewhat of an impact on the insurance industry.
Silica dioxide is a mineral. This is quartz or common sands basic constituent. Silicon is produced by heating sand SiO2 with carbon to temperatures around 2200176C. At room temperatures, silicon exists in two forms, amorphous and crystalline. Amorphous appears as a brown powder while crystalline silicon has a metallic luster and a grayish color.

For example, in 2016 OSHA changed its rules surrounding silica dust, a move that will affect many mining operations. OSHAs new rule cuts the permissible exposure limit PEL by half. The new limit is 50 micrograms per cubic meter of air, measured as an 8-hour time-weighted average.
Particle Size Sizes. The size of particulates is generally described by the quotaerodynamicquot diameter of the particles. Common size designations are PM 10 particles that are 10 micrometers um and smaller, PM 4 particles 4 um and smaller these are often referred to as quotrespirablequot, and PM 2.5 particles 2.5 um and smaller these are often called quotfinesquot.
Silica or materials with high silica content are used in glass, pottery, ceramics, refractory bricks, and artificial stone. About 2.3 million Americans are exposed to silica at work, especially workers in construction concrete, oil and gas fracking, manufacturing sandblasting, and agriculture.

Respirable crystalline silica exposure is measured using an air sampling device that is placed in the work area or worn by an employee. An industrial hygienist IH will generally oversee the sample collection. The samples are collected and sent to a qualified lab for analysis and the IH will review the results and make recommendations.
SILICA and SILICOSIS The Basics on Silica Silica is a mineral compound made up of one silicon atom and two oxygen atoms. Oxygen is the most abundant element in the earths crust. Silicon is the second most abundant. Due to such abundance, the formation of the compound silica in nature is very common.
Why is Silica Hazardous Silica, often referred to as quartz, is a very common mineral. It is found in many materials common on construction and oil amp gas sites, including soil, sand, concrete, masonry, rock, granite, and landscaping materials.

Relation to Mining. In almost all cases, silica mining uses open pit or dredging mining methods with standard mining equipment. Except for temporarily disturbing the immediate area while mining operations are active, sand and gravel mining usually has limited environmental impact.
The major environmental impacts associated with silicon derive from its mining. Carbon monoxide is a byproduct of the basic process whereby silicon is prepared from silicon dioxide, but this is a negligible source of atmospheric carbon, compared to the amount generated by combustion of fossil fuels.
Crystalline silica quartz is a natural mineral. Its found in stone products such as reconstituted stone, granite and sandstone. Its also in other building materials such as concrete, bricks and mortar. How much crystalline silica is present depends on the material. Reconstituted stone can have very high crystalline silica content up to 95.
