Contractors shall take all necessary steps to comply with the exposure limits for silica established in 29 CFR 1926.1153. The contractors written Exposure Control Plan must detail how potential exposure to NCSU personnel and the general public in adjacent areas will be kept below allowable limits.
Silica is found naturally in the environment. It is a compound made from silicon and oxygen and can come in different forms. All silica forms are made from the same chemicals but can have different structures. Silica is divided into two main groups, crystalline silica and amorphous silica non-crystalline silica. The most common type of crystalline silica is quartz.
6 1.3.2 MINE OPERATION The mineral proposed to be mined is Silica Sand. The method to be implemented is a very basic form of Open Cast Mining. Extraction of sand will be facilitated through the use of an excavator andor front end loader.
OSHA is advocating for reasonable steps that employers and work site managers can take to lessen harmful exposure to silica. In 2011, OSHA proposed new, lower permissible silica level guidelines. These guidelines would cut acceptable silica exposure limits in half the original guidelines were decades-old and outdated.

Crystalline silica, in the form of quartz, is one of the most abundant minerals in the Earths crust and is a common component of rock, sand and soil. Other forms of crystalline silica include cristobalite and tridymite. Amorphous silica is less hazardous than the crystalline forms. Glass is an example of amorphous silica.
Construction. OSHAs Respirable Crystalline Silica standard for construction requires employers to limit worker exposures to respirable crystalline silica and to take other steps to protect workers. The standard provides flexible alternatives, which OSHA expects will be especially useful for small employers.
