3. Hazard Identification
EMERGENCY OVERVIEW
This product is a white shape. It is not flammable, combustible or explosive. It does not cause burns or
severe skin or eye irritation. A single exposure will not result in serious adverse health effects.
Crystalline silica (quartz) is not known to be an environmental hazard.
Potential Health Effects
EYES: Irritation, Crystalline silica (quartz) may cause abrasion of the cornea.
SKIN: Not applicable.
INHALATION: Respirable crystalline silica (quartz) can cause silicosis, a fibrosis (scarring) of the
lungs; it may lead to disability and death. This product if inhaled from an occupational source is
classified as carcinogenic to humans. There is evidence that exposure to respirable crystalline
silica or that the disease silicosis is associated with the increased incidence of scleroderma, an
autoimmune disorder manifested by a fibrosis of the skin and internal organs. Silicosis is known
to increase the risk of tuberculosis. There are several studies that suggest an association between
exposure to respirable crystalline silica and increased incidence of nephrotoxicity (kidney
disorders).
INGESTION: Not applicable.
MEDICAL CONDITIONS AGGRAVATED: The condition of individuals with lung disease (e.g.,
bronchitis, emphysema, chronic obstructive pulmonary disease) can be aggravated by exposure.
P/N: 528-028
MATERIAL SAFETY DATA SHEET 01873 Pg. 2
CHRONIC OVEREXPOSURE: The adverse health effects 鈥? silicosis, cancer, scleroderma, tuberculosis, and
nephrotoxicity 鈥? are chronic effects.
ACUTE OVEREXPOSURE: Not available.
CARCINOGENICITY: IARC labels crystalline silica as a 2A (probable human) carcinogen.
4. First Aid Measures
EYES: Flush with water. If irritation persists, seek medical attention.
SKIN: Not applicable.
INHALATION: No specific first-aid necessary since the adverse effects associated with exposure to
crystalline silica (quartz) result from chronic exposures. If there is a gross inhalation of crystalline silica
(quartz), remove the person immediately to fresh air, give artificial respiration as needed and seek medical
attention.
INGESTION: Not applicable.
5. Fire Fighting Measures
FLAMMABLE PROPERTIES: Non-flammable/Non-explosive.
Flash Point: None. Method Used: Not applicable.
Flammable Limits (% by Volume in Air):
Lower: None. Upper: None.
AUTO-IGNITION TEMPERATURE: Not applicable.
HAZARDOUS COMBUSTION PRODUCTS: Not available.
EXTINGUISHING MEDIA: Not available.
FIREFIGHTING INSTRUCTIONS: Not available.
6. Accidental Release Measures
SMALL/LARGE SPILL: Use dustless methods (HEPA vacuum) and place into closable container for
disposal, or flush with water. Do not dry sweep. Wear appropriate respirator and other personal
protective equipment if conditions call for it.
7. Handling and Storage
HANDLING: Do not breathe dust. Use adequate ventilation and dust collection. Keep airborne dust
concentrations below PEL. Practice good housekeeping. Do not allow dust to collect on walls, floors,
sills, ledges, machinery, or equipment. Properly clean, maintain and fit test respirators in accordance with
OSHA regulations. Maintain and test ventilation and dust collection equipment regularly.
STORAGE: Keep container closed. Avoid breakage of bagged material or spills of bulk material.
8. Exposure Controls/Personal Protection
ENGINEERING CONTROLS: Provide sufficient mechanical (General and/or Local Exhaust) ventilation to
maintain exposure below TLVs or PELs. See ACGIH 鈥淚ndustrial Ventilation, A Manual of
Recommended Practice鈥? (latest edition).
RESPIRATORY PROTECTION: Recommended if TLVs or PELs are exceeded. Use NIOSH/MSHA
approved dust respirators.
SKIN AND HAND PROTECTION: Rubber or leather gloves recommended.
EYE AND FACE PROTECTION: Safety glasses with side shields.
OTHER PROTECTIVE EQUIPMENT: Protective shoes recommended (steel toe type).E

11. Toxicological Information
IARC 鈥? The International Agency for Research on Cancer concluded that there is 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
and 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?
NTP 鈥? The National Toxicology Program, in its Sixth Annual Report on Carcinogens, concluded that 鈥渟ilica,
crystalline (respirable)鈥? may be reasonably anticipated to be a carcinogen, based on sufficient evidence in
experimental animals and limited evidence in humans.
OSHA 鈥? Crystalline silica (quartz) is not regulated by the U.S. Occupational Safety and Health
Administration as a carcinogen.
