OSHA Construction Standard. On March 24, 2016, OSHA issued a final silica standard for the construction industry. The new standard went into effect on June 23, 2016, and OSHA began enforcement on September 23, 2017. Challenges to the standard were dismissed by the United States Court of Appeals for the District of Columbia Circuit in December 2017.

New OSHA Silica Testing Requirement in Effect. OSHA has issued two standards (“rules”) to minimize exposure to respirable crystalline silica. One rule applies to construction trades, and the other for general industry and maritime workplaces. This blog focuses on the new OSHA Silica Testing requirements for the construction industry.
Sandblasting with silica-based material, such as sand, poses a potential hazard to the person performing the blasting, as well as others around the blasting area. If performed personally on private property away from others, no federal laws restrict the sandblasting act. However, sandblasting performed for
OSHA Silica Dust Standards Clearing the air on the OSHA respirable crystalline silica dust regulation. We have designed this resource to help professionals just like you in the construction industry better understand and comply with the OSHA 1926.1153 Table 1 regulations for silica dust exposure.
The most common constituent of sand, in inland continental settings and non-tropical coastal settings, is silica (silicon dioxide, or SiO 2), usually in the form of quartz, which, because of its chemical inertness and considerable hardness, is the most common mineral resistant to weathering.. The composition of mineral sand is highly variable, depending on the local rock sources and conditions.
Employer responsibilities for limiting silica dust inhalation. The specific requirements for minimizing levels of silica dust on jobsites are outlined in OSHA regulation 29 CFR 1926.1153.In general, employers must implement the use of engineering controls in conjunction with jobsite equipment to regulate silica dust to the minimum permissible exposure limit, or PEL.
Millions of U.S. workers are exposed to respirable crystalline silica in a variety of industries and occupations, including construction, sandblasting, and mining. Silicosis, an irreversible but preventable disease, is the illness most closely associated with occupational exposure to the material ...
Silica is the basic component in sand and rock. It's in construction materials such as: Concrete, concrete block, cement, and mortar Masonry, tiles, brick, and refractory brick Granite, sand, fill dirt, and top soil Asphalt-containing rock or stone Abrasive used for blasting Silica is the most common hazard on a
In 2013, the legislature directed the DNR to adopt rules pertaining to the reclamation of silica sand mines. The DNR used input gained from a nearly year-long advisory panel process to develop preliminary draft rules. Developing rules can take about two years. The process can take longer to ...
NOTICE as of June 2019: We have closed the silica sand rulemaking case. The DNR had not yet formally proposed rules. By Minnesota Laws 2019, 1st Special Session, Chapter 4, Article 3, Section 108, the legislature replaced the rulemaking authority with a requirement that the DNR develop a model ...
Jan 05, 2017 The Environmental Quality Board shall consider whether the requirements of Minnesota Statutes, section 116C.991, should remain part of the environmental review requirements for silica sand and whether the requirements should be different for different geographic areas of the state: Silica Sand Rulemaking
Respirable Crystalline Silica • Silica is a natural substance that is present in many parts of the earth • Found in Construction Materials Like Sand, Gravel, Concrete Blocks, Stones and Mortar • Respirable Crystalline Silica is generally attributed to certain construction operations
Silica is a natural mineral that comes in several forms, some more hazardous than others. Typically, it’s the crystalline forms that are of greatest concern. Silica can be present in large quantities in certain types of rocks and sand. Construction materials made from these natural ingredients then become

OSHA announced a final rule for respirable silica dust on March 24, 2016. It is unlikely that existing plants meet new limit of 50 ug/m3. General Industry (including frac sand manufacturers) have until June 23, 2018, to comply with most requirements.
Respirable dust from silica sand and other abrasive materials pose a risk to the lungs. Where abrasive blasting is used to remove lead-based paint on the steel infrastructure of bridges, it can generate particles of lead that pose a risk to the nervous system. In addition to potential health hazards, abrasive blasting can pose safety risks as well.

Silica sand for making glass, pottery and ceramics must meet rigid specifications and generally standard washing schemes are inadequate for meeting these requirements. Sand for the glass industry must contain not more than 0.03% Fe2O3. Concentrating tables will remove free iron particles but iron stained and middling particles escape gravity ...
May 19, 2016 You’ll find silica in a lot of places — food, rocks, plants, medicine, cosmetics, toothpaste, and those little dry gel packs that are packed in with product packaging to absorb moisture. There’s even silica in your body. The most common form of silica is quartz, a component of stone, concrete, and sand. Simply put, silica is everywhere.
