V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of calcium carbonate have not been thoroughly investigated and recorded

Calcium compounds are generally considered to have low toxicity as a nuisance material.

Acute Effects:

Inhalation:  May cause irritation to the respiratory tract.

Ingestion:  No acute health effects recorded.

Skin:  May cause moderate irritation

Eye:  May cause severe irritation.

Chronic Effects:  Chronic ingestion may cause alkalosis.  No other chronic effects recorded.

Medical Conditions Generally Aggravated by Exposure:  No data

Carcinogenicity:  NTP:  No IARC:  No             OSHA:  No

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove victim to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek medical attention if symptoms persist.

INGESTION: Give 1-2 glasses of milk or water and induce vomiting, seek medical attention.  Never induce vomiting or give anything by mouth to an unconscious person. 

SKIN:  Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water.  Seek medical attention if symptoms persist.

EYES:  Flush with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes.  Seek medical attention if symptoms persist.

VI.   REACTIVITY DATA
