Crystalline Silica.
(1) Contains less than 1% crystalline silica
SECTION III - PHYSICAL/CHEMICAL CHARACTERISTICS
Appearance: Gray to gray-brown colored powder.
Melting Point: >27000F >27000F
Specific Gravity: 3.0 to 3.15 Boiling Point:
Vapor Pressure: None Vapor Density: None Evaporation Rate: None
Solubility in Water: Slight Odor: None pH: 11.5-12.5
SECTION IV - FIRE AND EXPLOSION HAZARD DATA
Flammability: Noncombustible and not explosive.
SECTION V - REACTIVITY DATA
Stability: Stable.
Incompatibility (Materials to Avoid): Contact of silica with powerful oxidizing agents such as fluorine, chlorine
trifluoride, manganese trioxide, oxygen difluoride, may cause fires.
High Performance Pace Accelerator MSDS V3 page # 2
Hazardous Decomposition or By-products: Silica will dissolve in Hydrofluoric Acid and produce a corrosive gas -
silicon tetrafluoride.
Hazardous Polymerization: Will Not Occur.
Condition to Avoid: Keep dry until used to preserve product utility.
SECTION VI - HEALTH HAZARD DATA
Route(s) of Entry: Inhalation, Skin, Ingestion
Acute Exposure: Product becomes alkaline when exposed to moisture. Exposure can dry the skin, cause alkali burns
and effect the mucous membranes. Dust can irritate the eyes and upper respiratory system. Toxic effects noted in
animals include, for acute exposures, alveolar damage with pulmonary edema.
Chronic Exposure: Dust can cause inflammation of the lining tissue of the interior of the nose and inflammation of the
cornea. Hypersensitive individuals may develop an allergic dermatitis. Respirable crystalline silica (quartz) can cause
silicosis, a fibrosis (scarring) of the lungs and possibly cancer. There is evidence that exposure to respirable silica or the
disease silicosis is associated with an increased incidence of Scleroderma, tuberculosis and kidney disorders.
Carcinogenicity Listings: NTP: Known carcinogen
OSHA: Not listed as a carcinogen
IARC Monographs: Group 1 Carcinogen
California Proposition 65: Known carcinogen
NTP: The National Toxicology Program, in its 鈥淣inth Report on Carcinogens鈥? (released May 15, 2000) concluded that
鈥淩espirable crystalline silica (RCS), primarily quartz dusts occurring in industrial and occupational settings, is known to
be a human carcinogen, based on sufficient evidence of carcinogenicity from studies in humans indicating a causal
relationship between exposure to RCS and increased lung cancer rates in workers exposed to crystalline silica dust
(reviewed in IAC, 1997; Brown et al., 1997; Hind et al., 1997)
IARC: The International Agency for Research on Cancer (鈥淚ARC鈥?) concluded that there was 鈥渟ufficient evidence in
humans for the carcinogenicity of crystalline silica in the forms of quartz or cristobalite from occupational sources鈥?, and
that there is 鈥渟ufficient evidence in experimental animals for the carcinogenicity of quartz or cristobalite.鈥? The overall
IARC evaluation was that 鈥渃rystalline silica inhaled in the form of quartz or cristobalite from occupational sources is
carcinogenic to humans (Group 1).鈥? The IARC evaluation noted that 鈥渃arcinogenicity was not detected in all industrial
circumstances or studies. Carcinogenicity may be dependent on inherent characteristics of the crystalline silica or on
external factors affecting its biological activity or distribution of its polymorphs.鈥? For further information on the IARC
evaluation, see IARC Monographs on the Evaluation of carcinogenic Risks to Humans, Volume 68, 鈥淪ilica, Some
Silicates...鈥? (1997)
Signs and Symptoms of Exposure: Symptoms of excessive exposure to the dust include shortness of breath and
reduced pulmonary function. Excessive exposure to skin and eyes especially when mixed with water can cause caustic
burns as severe as third degree.
Medical Conditions Generally Aggravated by Exposure: Individuals with sensitive skin and with pulmonary and/or
respiratory disease, including, but not limited to, asthma and bronchitis, or subject to eye irritation, should be precluded
from exposure. Exposure to crystalline silica or the disease silicosis is associated with increased incidence of
scleroderma, Tuberculosis and possibly increased incidence of kidney lesions.
Emergency First Aid Procedures:
Eyes: Immediately flush eye thoroughly with water. Continue flushing eye for at least 15 minutes, including under lids,
to remove all particles. Call physician immediately.
Skin: Wash skin with cool water and pH-neutral soap or a mild detergent. Seek medical treatment if irritation or
inflammation develops or persists. Seek immediate medical treatment in the event of burns.
High Performance Pace Accelerator MSDS V3 page # 3
Inhalation: Remove person to fresh air. If breathing is difficult, administer oxygen. If not breathing, give artificial
respiration. Seek medical help if coughing and other symptoms do not subside. Inhalation of large amounts of portland
cement require immediate medical attention.
Ingestion: Do not induce vomiting. If conscious, have the victim drink plenty of water and call a physician immediately.
SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE
Spills: If spilled, use dustless methods (vacuum) and place into covered container for disposal or use if not
contaminated or wet. Use adequate ventilation.
Waste Disposal Method: The packaging and material may be land filled; however, material should be covered to
minimize generation of airborne dust. This product is not classified as a hazardous waste under RCRA or CERCLA.
SECTION VIII - CONTROL MEASURES/PERSONAL PROTECTION
Inhalation: DO NOT BREATH DUST. In dusty environments, the use of an OSHA, MSHA or NIOSH approved
respirator is recommended. Local exhaust can be used, if necessary, to control airborne dust levels.
Eyes: Wear tight fitting goggles.
Skin: The use of barrier creams or impervious gloves, boots and clothing to protect the skin from contact is
recommended. Following work, workers should shower with soap and water. Precautions must be observed because
burns occur with little warning -- little heat is sensed.
WARN EMPLOYEES AND/OR CUSTOMERS OF THE HAZARDS AND REQUIRED OSHA PRECAUTIONS
ASSOCIATED WITH THE USE OF THIS PRODUCT.
