Supplemental Information Respirable Crystalline Silica (RCS) may cause cancer. Sand and Gravel is a naturally occurring mineral complex that contains varying quantities of quartz (crystalline silica). In its natural bulk state, Sand and Gravel is not a known health hazard. Sand and Gravel may be subjected to various natural or mechanical forces that produce small particles (dust) which may contain respirable crystalline silica (particles less than 10 micrometers in aerodynamic diameter). Repeated inhalation of respirable crystalline silica (quartz) may cause lung cancer according to IARC and NTP; ACGIH states that it is a suspected cause of cancer. Other forms of RCS (e.g., tridymite and cristobalite) may also be present or formed under certain industrial processes.

Inhalation Sand and Gravel dust: Move to fresh air. Call a physician if symptoms develop or persist.
Skin contact Sand and Gravel dust: Wash off with soap and water. Get medical attention if irritation develops and persists.
Eye contact Sand and Gravel dust: Immediately flush with plenty of water for at least 15 minutes. Hold eyelids apart. Occasionally lift the eyelid(s) to ensure thorough rinsing. Beyond flushing, do not attempt to remove material from the eye(s). Get medical attention if irritation develops or persists.
Ingestion Sand and Gravel dust: Rinse mouth and drink plenty of water. Never give anything by mouth to an unconscious person. Get medical attention.
Most important symptoms/effects, acute and delayed Inhaling dust may cause discomfort in the chest, shortness of breath, and coughing. Prolonged inhalation may cause chronic health effects. This product contains crystalline silica. Prolonged or repeated inhalation of respirable crystalline silica liberated from this product can cause silicosis and may cause cancer.
Indication of immediate medical attention and special treatment needed Provide general supportive measures and treat symptomatically. Keep victim under observation. Symptoms may be delayed.
General Information Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves. Pre‐existing medical conditions that may be aggravated by exposure include disorders of the eye, skin and lung (including asthma and other breathing disorders). If addicted to tobacco, smoking will impair the ability of the lungs to clear themselves of dust.
Suitable extinguishing media Non‐flammable. Use fire‐extinguishing media appropriate for surrounding materials
Unsuitable extinguishing media None known
Specific hazards arising from the chemical No unusual fire or explosion hazards noted. Not a combustible dust.
Special protective equipment and precautions for firefighters Use protective equipment appropriate for surrounding materials.
Firefighting equipment/instructions No Specific precautions.
Specific methods Contact with powerful oxidizing agents may cause fire and/or explosions (see section 10 of SDS)
General fire hazards No unusual fire or explosion hazards noted.
Personal precautions and emergency procedures Wear appropriate protective equipment and clothing during clean-up of materials that contain or may liberate Sand and Gravel dust
Materials and methods for containment and clean-up Spilled material, where dust is generated, may overexpose cleanup personnel to respirable crystalline silica-containing dust. Do not dry sweep or use compressed air for clean-up. Wetting of spilled material and/or use of respiratory protective equipment may be necessary.
Environmental Precautions Avoid discharge of fine particulate matter into drains or water courses.
Precautions for safe handling Do not handle until all safety precautions have been read and understood. Keep formation of airborne dusts to a minimum. Provide appropriate exhaust ventilation at places where dust is formed. Do not breathe dust. Avoid prolonged exposure. Provide adequate ventilation. Wear appropriate personal protective equipment. Observe good industrial hygiene practices.
Conditions for safe storage Avoid dust formation or accumulation.

Biological limit values No biological exposure limits noted for the ingredient(s).
Exposure guidelines OSHA PELs, MSHA PELs, and ACGIH TLVs are 8-hr TWA values. NIOSH RELs are for TWA exposures up to 10- hr./day and 40-hr/wk. Occupational exposure to nuisance dust (total and respirable) and respirable crystalline silica should be monitored and controlled. Terms including "Particulates Not Otherwise Classified," "Particulates Not Otherwise Regulated," "Particulates Not Otherwise Specified," and "Inert or Nuisance Dust" are often used interchangeably; however, the user should review each agency's terminology for differences in meanings.
Appropriate engineering controls Good general ventilation (typically 10 air changes per hour indoors) should be used. Ventilation rates should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation, or other engineering controls to maintain airborne levels below recommended exposure limits. If exposure limits have not been established, maintain airborne levels to an acceptable level.

Individual protection measures, such as personal protective equipment

Eye/face protection Wear safety glasses with side shields (or goggles).
Skin protection Use personal protective equipment as required.
Respiratory protection When handling or performing work with Limestone that produces dust or respirable crystalline silica in excess of applicable exposure limits, wear a NIOSH‐approved respirator that is properly fitted and is in good condition. Respirators must be used in accordance with all applicable workplace regulations.
Thermal hazards Not anticipated. Wear appropriate thermal protective clothing, when necessary.
General hygiene considerations Always observe good personal hygiene measures, such as washing after handling the material and before eating, drinking, and/or smoking. Routinely wash work clothing and protective equipment to remove contaminants.

Information on likely routes of exposure

Inhalation Repeated inhalation of respirable crystalline silica (quartz) may cause silicosis, a fibrosis (scarring) of the lungs. Silicosis is irreversible and may be fatal. Silicosis increases the risk of contracting pulmonary tuberculosis. Some studies suggest that repeated inhalation of respirable crystalline silica may cause other adverse health effects including lung and kidney cancer.
Skin contact Sand and Gravel dust: May cause irritation through mechanical abrasion.
Eye contact Sand and Gravel dust: May cause irritation through mechanical abrasion.
Ingestion Not likely, due to the form of the product. However, accidental ingestion of the content may cause discomfort.
Symptoms related to the physical, chemical and toxicological characteristics Sand and Gravel dust: Discomfort in the chest. Shortness of breath. Coughing.

OSHA Specifically Regulated Substances (29 CFR 1910.1001‐1050)

Reproductive toxicity Not expected to be a reproductive hazard.
Specific target organ toxicity ‐ single exposure Not classified.
Specific target organ toxicity -repeated exposure Respirable crystalline silica: May cause damage to organs (lung) through prolonged or repeated exposure.
Aspiration hazard Due to the physical form of the product it is not an aspiration hazard.
Chronic effects Prolonged inhalation of respirable crystalline silica may be harmful. May cause damage to organs (lungs) through prolonged or repeated exposure. There are reports in the literature suggesting that excessive crystalline silica exposure may be associated with autoimmune disorders and other adverse health effects involving the kidney. In particular, the incidence of scleroderma (thickening of the skin caused by swelling and thickening of fibrous tissue) appears to be higher in silicotic individuals. To date, the evidence does not conclusively determine a causal relationship between silica exposure and these adverse health effects.
Ecotoxicity Not expected to be harmful to aquatic organisms. Discharging Limestone dust and fines into waters may increase total suspended particulate (TSP) levels that can be harmful to certain aquatic organisms.
Persistence and degradability Not applicable.
Bioaccumulative potential Not applicable.
Mobility in soil Not applicable.
Other adverse effects No other adverse environmental effects (e.g., ozone depletion, photochemical ozone creation potential, global warming potential) are expected from this component.
Disposal instructions Do not allow fine particulate matter to drain into sewers/water supplies. Do not contaminate ponds, waterways or ditches with fine particulates. Dispose of contents in accordance with local/regional/national/international regulations.
