Ingredients: Wt. % (typical): CAS #: Exposure Limits (TWA) mg/m鲁:
Limestone > 99 1317-65-3 ACGIH: Inhalable dust, 10 [for PNOS]
Respirable dust, 3 [for PNOS]
OSHA PEL: Total dust, 15
Respirable dust, 5
Silica, total quartz (naturally-occurring 1.6 14808-60-7 OSHA PEL: Total dust, 30 / % silica +2
component of limestone)
Silica, respirable quartz (naturally-occurring < 0.1 14808-60-7 ACGIH TLV: Respirable dust, 0.025

SECTION 3 鈥? PHYSICAL DATA
Appearance and Odor: White powder; no odor.
Density: 2.7 g/ml
Solubility in Water: 1.3 mg/100 g @ 18掳C
SECTION 4 鈥? FIRE AND EXPLOSION DATA
Flash Point: Non-flammable.
Special Fire Fighting Procedures: None.
Unusual Fire and Explosion Hazards: None.
SECTION 5 鈥? REACTIVITY DATA
Stability: Stable.
Reactivity in Water: None.
Hazardous Polymerization: Will not occur.
Hazardous Decomposition Products: Thermal decomposition of limestone beginning at 550掳C (1022掳F) can produce calcium oxide
and carbon dioxide. Heating of this product above 244掳C (471掳F) may cause volatilization
and/or thermal decomposition of processing aids, resulting in the gaseous release of trace
amounts of organic compounds.
Incompatibility (Material to Avoid): Reacts with acids to liberate carbon dioxide. Ignites on contact with fluorine. Also incompatible
with alum and ammonium salts.

SECTION 6 鈥? TOXICOLOGICAL PROPERTIES
EFFECTS AND HAZARDS OF ACUTE EXPOSURE:
Inhalation: Dust may irritate the respiratory tract. Symptoms include sneezing and slight nose irritation.
Eye Contact: Irritation. Symptoms include watering and irritation.
Skin Contact: Repeated or prolonged exposure may have a drying effect on the skin, and may also cause irritation.
Ingestion: Ingestion of very large quantities may result in intestinal obstruction and/or constipation.
EFFECTS AND HAZARDS OF CHRONIC EXPOSURE:
Chronic exposure to limestone dust at concentrations exceeding occupational exposure limits may cause pneumoconiosis (lung
disease). This product contains crystalline silica (quartz) and non-asbestos tremolite as impurities. Chronic exposure to crystalline
silica dust at concentrations exceeding occupational exposure limits may cause silicosis. The NTP鈥檚 Ninth Report on Carcinogens lists
crystalline silica (respirable size) as a known human carcinogen. IARC concluded that there is sufficient evidence in humans for the
carcinogenicity of inhaled (respirable) crystalline silica. Non-asbestos tremolite is considered to be a nuisance dust, although some
studies suggest that sufficient exposure to respirable non-asbestos tremolite dust may increase the risk of developing cancer and/or
other asbestos-related diseases.
SECTION 7 鈥? PREVENTIVE MEASURES
Handling: Administrative and/or engineering control methods such as, but not limited to, process enclosure and exhaust ventilation
may be necessary to control exposures to dust and/or gaseous organic compounds. Supply sufficient replacement air to
make up for air removed by exhaust systems. If engineering controls and work practices are not effective in controlling
exposures, appropriate personal protective equipment including a NIOSH/OSHA approved respirator should be worn.
When repeated or prolonged contact with hands is likely, appropriate gloves should be used. Appropriate eye protection
should be worn. Selection of all personal protective equipment should be performed by an Industrial Hygienist or other
qualified professional.
Hazardous Materials Identification System Category Rating
(National Paint & Coatings Association) Health 1*
Flammability 0
Physical Hazard 0
Storage: Store in closed containers in a dry place separate from incompatible materials.
Spills/Leaks: Measures should be taken to minimize and protect against airborne dust during cleanup operations, including use of
respiratory protective equipment if necessary.
Disposal: From a waste perspective, this product is not considered hazardous and may be disposed of as solid waste in
accordance with applicable federal, state, provincial, and local regulations.
SECTION 8 鈥? FIRST AID MEASURES
Inhalation: Remove to fresh air. Obtain medical advice if required.
Eye Contact: Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 10 minutes holding the eyelid(s)
open. If irritation persists, obtain medical advice immediately.
Skin Contact: Wash with warm water and mild soap. If irritation occurs, obtain medical advice immediately.
Ingestion: Never give anything by mouth if victim is rapidly losing consciousness or is unconscious or convulsing. Rinse mouth
thoroughly with water. Do not induce vomiting. Drink 8 to 10 ounces (240 to 300 ml) of water to dilute material in
stomach. Obtain medical advice immediately.

SECTION 9 鈥? REGULATORY INFORMATION
TSCA: This product primarily is natural calcium carbonate from limestone ore which is listed on the U.S. EPA TSCA inventory under
Limestone, CAS# 1317-65-3. In addition, all other ingredients and/or processing aids also are on the TSCA inventory.
DSL: By virtue of its status as a 鈥渟ubstance occurring in nature鈥?, ground limestone is considered to be on the Canadian Domestic
Substances List. In addition, all other ingredients and/or processing aids also are on the DSL.
CONEG: Being derived from limestone ore, this product may contain incidental trace levels of naturally occurring metals. However, no
+6
metals are intentionally added and this product complies with the CONEG requirement of <100 ppm of Cd, Cr , Pb, and Hg.
ODCs: This product does not contain, nor is it produced with, any U.S. EPA-defined Class I or Class II ozone-depleting chemicals.
FDA: This product may be used as an indirect food additive in food packaging applications under 21 CFR (FDA) 174.5, 175.300,
and 178.3297. It does not qualify as a substance permitted for direct addition to human food or animal feed.
