3. COMPOSITION/INFORMATION ON INGREDIENTS
INGREDIENTS Name CAS Proportion
Limestone (CaCo3) 1317-65-3 >99%
Natural, ground Limestone – calcium carbonate. Also referred to as Calcite or Marble.
Naturally occurring sedimentary rock. Limestone (Ground): CAS-No. 1317-65-3
Ground with non-hazardous auxiliary agents
Silica, quartz (CAS No 14808-60-7) naturally-occurring impurity of Limestone in trace
amounts. Magnesium Carbonate (CAS No 13717-00-5) is also naturally present.
4. FIRST AID MEASURES
EYE CONTACT: Rinse with plenty of clean water.
In case of continued irritation, seek medical advice.
SKIN CONTACT: Wash with water.
INHALATION: Move person to fresh air.
In case of indisposition, seek medical advice.
INGESTION: Symptomatic treatment.
In case of indisposition, seek medical advice.
5. FIRE FIGHTING MEASURES
FLAMABILITY: Non-flammable, non- combustible substance.
SPECIAL RISKS: Can release CO2 or CO in extreme temperature conditions i.e. > 825 °C.
EXTINGUISHING AGENTS: All common extinguishing media compatible.
HAZCHEM CODE: Not regulated.
6. ACCIDENTAL RELEASE MEASURES
PRECAUTIONS: Will not dissolve in water. Do not flush down drains or into water ways.
Slippery when wet – cordon off for road and pedestrian traffic. Avoid contact with acids.
CONTAINMENT AND
CLEAN UP:
In case of spillage, avoid generating dust, wear respiratory protection when visibly dusty or
for prolonged exposure, and sweep or vacuum. Very fine products should be collected in
bag/containers, label appropriately.
May be lightly wetted down to minimise dust.
Cover or lightly wet down to minimize dust generation if spills cannot be dealt with
immediately.
7. HANDLING AND STORAGE
HANDLING: Avoid generating airborne dust during handling and storage.
Avoid prolonged contact with skin.
Avoid heavy or prolonged dust inhalation (See TWA Section 8).
Engineering dust controls should be used ahead of, or in combination with the wearing of
appropriate respiratory protection.
STORAGE: Store in original packaging, under dry conditions.
Do not store with acids.
Keep fine products stored in closed containers. Avoid the generation of airborne dust.
8. EXPOSURE CONTROL / PERSONAL PROTECTION
HAND PROTECTION: Wear gloves to prevent irritation and drying out skin.
EYE PROTECTION: Wear goggles if visible dust in air or if irritation occurs.
Do not wear contact lenses when handling this product, as particles may get
trapped underneath and cause irritation.
SKIN PROTECTION: Clothing fully covering skin, full length pants, long sleeved overalls, with close fittings at
openings. Footwear to avoid dust penetration.
RESPIRATORY
PROTECTION
Maintain air concentrations below the occupational exposure standards, using
engineering controls if necessary.
Where this is not possible, wear an approved P1 dust mask where concentration
is less than 10 times permissible exposure limit.
ASCC* TWA for CaCO3 Inhalable Dust in Australia is: 3 mg/m3
ACGIH** TLV for CaCO3 Respirable Dust in Australia is: 10 mg/m3
ASCC TWA for Respirable Quartz in Australia is: 0.1 mg/m3

12. ECOLOGICAL INFORMATION
In its solid state, calcium carbonate is a natural mineral of the earth. In its dissolved state, the substance is a natural and
indispensable component of natural waters.
Toxicity
LC50 Fish 96 h > 10’000 mg/l
LC50 Daphnia 49 h > 1000 mg/l
LC50 Algae 72 h > 200 mg/l
Persistence &
degradability
Not readily degradable, except in acid conditions where it tends to have a neutralizing effect.
Bioaccumulative
potential
Calcium carbonate is a naturally occurring inorganic compound which has constituent
elements that make up natural components of biological organisms.
Mobility in soil Calcium carbonate is practically insoluble except in acid conditions, and so presents a low
soil mobility in most ground. Moreover it is commonly used as an effective soil conditioner
and fertiliser.
13. DISPOSAL CONSIDERATIONS
Dispose of in appropriately licensed general landfill site in accordance with local, state and
federal regulations. Waste should be bagged and labelled. Special arrangements made to
bury bulk waste upon dumping, limiting dust generation.
