Section V - Reactivity Data
------------------------------------------------------------------------------------------------------------------
Stability: Stable under normal temperatures and pressures.
Incompatibility (Materials to avoid): Vigorous release of carbon dioxide when contacted with strong
acids. Reacts violently with fluorine gas.
Hazardous Decomposition or By-Products: When heated at temperatures above 900oC (1652oF) carbon
dioxide is liberated thereby forming calcium oxide.
Hazardous Polymerization: Does not polymerize.

Section VI - Health Hazard Data
------------------------------------------------------------------------------------------------------------------
Acute Effects: Calcium carbonate can be a simple mechanical irritant to the eyes, skin and upper respiratory
system.
Exposure to respirable
Chronic Effects: No known effects from exposure to calcium carbonate.
crystalline silica without the use of a respirator can cause silicosis and may aggravate other lung
conditions.
Signs and Symptoms of Exposure: As with any inert foreign object, calcium carbonate may cause
irritation if it enters the eye. Skin redness may result if contact is due to abrasion. Silicosis is characterized
by shortness of breath, coughing, diminished work capacity, reduced lung volume and heart enlargement or
failure.
Medical Conditions Aggravated by Exposure: Pre-existing skin conditions may be worsened. Silicosis
may aggravate other chronic pulmonary conditions and may increase the risk of pulmonary tuberculosis
infection.
Chemical Listed as Carcinogenic or Potential Carcinogen: Calcium carbonate is not considered
carcinogenic. However, the International Agency for Research on Cancer (IARC) has determined, primarily
through animal studies, that silica is a known human carcinogen. The National Toxicology Program (NTP)
has characterized respirable quartz silica as reasonably anticipated to be a carcinogen. OSHA does not
regulate silica as a carcinogen.
Emergency First Aid Procedures: Remove from eyes as would be done with any inert foreign object. Seek
medical attention if irritation persists

Section VII - Precautions for Safe Handling and Use
---------------------------------------------------------------------------------------------------------------------------
Steps to be Taken in Case Material is Released or Spilled:
Pick up spilled powder avoiding dusting conditions. Can be disposed as non-hazardous waste or reused. Wet
sweeping may be used to avoid dusting. Residues can be flushed with water. Large quantities should not be
flushed to surface waters or sewers.
Precautions to be Taken in Handling and Storing:
Handling: Avoid generation of excessive dust.
Storing: Protect against physical damage and store in dry place only to preserve product integrity.
---------------------------------------------------------------------------------------------------------------------------
Section VIII - Control Measures
---------------------------------------------------------------------------------------------------------------------------
Ventilation: Provide local exhaust ventilation or general dilution ventilation to meet permissible exposure
limits for particulates.
Respiratory Protection: Avoid actions that cause dust to become airborne. Use NIOSH/MSHA-approved
(under 30 CFR 11) or NIOSH-approved (under 42 CFR 84) respirators (with dust filtering capability) in
poorly ventilated areas, if an applicable exposure limit is exceeded, or when dust causes discomfort or
irritation. (Advisory: Respirators and filters purchased after July 10, 1998, must be certified under 42 CFR
84.)
Firefighting: Not Applicable
Eye Protection: Exposed individuals should wear tight fitting goggles in dusty areas.
This product neither contains nor is directly manufactured with any
controlled ozone depleting substances, Class I and II.
