Section 3 - Hazards Identification
Emergency Overview
Appearance: white solid
Warning! Causes eye, skin, and respiratory tract irritation. May cause central nervous system effects. May cause kidney damage.
Target Organs: Kidneys, central nervous system.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
Causes skin irritation
Ingestion:
Ingestion of large amounts may cause gastrointestinal irritation. Expected to be a low ingestion hazard.
Inhalation:
Low hazard for industrial use. Excessive inhalation may cause minor respiratory irritation.
Material Safety Data Sheet
Calcium carbonate
Chronic:
Chronic ingestion may cause hypercalcemia, alkalosis, and kidney damage. May also produce “milk-alkali syndrome” characterized by neurological symptoms such as irritability, lethargy, stupor, and coma.
Section 4 - First Aid Measures
Eyes:
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids until no evidence of chemical remains. Get medical aid at once.
Skin:
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops.
I ngestion:
Do not induce vomiting. If victim is conscious, give 2-4 glasses of water or milk. Get medical aid at once.
I nhalation:
Give artificial respiration if necessary. Move victim to fresh air. Keep victim warm and at rest. Get medical aid at once.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
General Information:
Irritating and highly toxic gases may be generated by thermal decomposition or combustion. Substance is non-combustible but may decompose upon heating to produce irritating, corrosive, or toxic gases. Move container if possible; avoid breathing vapors or dust.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam.
Autoignition Temperature:
No information found.
Flash Point:
No information found.
NFPA Rating:
Health-1; flammability-0; reactivity-0
Explosion Limits:
Lower: n/a Upper: n/a
Section 6 - Accidental Release Measures
General Information:
Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately. Avoid creating airborne particles. Provide ventilation.
