SECTION VI - HEALTH HAZARD DATA

PRIMARY ROUTES OF ENTRY: INHALATION: Yes
SKIN ABSORPTION: Yes
INGESTION: Yes
CARCINOGENICITY: NTP: Known carcinogen OSHA: Not listed as a carcinogen
IARC MONOGRAPH: Group I Carcinogen
California Proposition 65: Known carcinogen
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.
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 I).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.
EMERGENCY FIRST AID PROCEDURES: Irrigate (flood) eyes immediately and repeatedly with clean water. Wash exposed skin
areas with soap and water. If irritation or inflammation occurs seek prompt medical attention. For gross inhalation, remove person
immediately to fresh air, give artificial respiration as needed. Get prompt medical attention.
SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE
SPILLS: If spilled, use dustless methods (vacuum) and place into closable 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.
Gravel Mix, Mortar Mix, Sand Mix, etc.
SECTION VIII - CONTROL MEASURES
INHALATION: DO NOT BREATHE DUST. Where exposure limit is exceeded, the use of an OSHA, MSHA or NIOSH approved
Page 2
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 鈥? little heat is sensed.
WARN EMPLOYEES AND/OR CUSTOMERS OF THE HAZARDS AND REQUIRED OSHA PRECAUTIONS ASSOCIATED WITH
THE USE OF THIS PRODUCT.
