Dragon Pelletized Limestone

October 8, 1993

_____________________________________________________________

Section I - Identity

_____________________________________________________________

Manufacturer's Name          Dragon Products Company, Inc.

and Address:                P. O. Box 191

Thomaston, Maine 04861

Emergency Telephone Number:  (207) 594-5555

Chemical Name and Synonyms:  Dolomite (CAS #16389-88-1)

Trade Name and Synonyms:     Dragon Pelletized Limestone

_____________________________________________________________

Section II - Chemical Data

_____________________________________________________________

Chemical Family:  Carbonate of calcium and magnesium

CaMg(CO3)2

In ordinary dolomite the proportion of CaCO3 to MgCO3 is 1:1.  However, substitutions between calcium and magnesium may alter this ratio slightly.  Dolomite occurs chiefly in widely extended rock masses as dolomitic limestone and the crystallized equivalent, dolomitic marble.

Section VI - Health Hazard Data

_____________________________________________________________

Exposure Limits:  Dolomite:  5mg/m3 respirable nuisance dust-  OSHA; 10mg/m3 - ACGIH

Quartz:  0.1mg/m3 (respirable dust)- ACGIH,OSHA

Primary Routes of Exposure:  Inhalation and eye contact.

Effects of Overexposure:   Acute:  Irritation of eye, throat and nose.

Chronic:  Crystalline silica may

cause cancer based on

animal data with limited

evidence in humans.

Emergency and First Aid Procedures:  Eye contact:  Flush with large amounts of water for 15 minutes.  If ingested, consult a physician immediately. Skin contact: Wash with ample amounts of water.

Medical Conditions Aggravated by Exposure:  None known.

Hazardous Chemicals Found on NTP, IARC or OSHA Carcinogens List:  IARC has concluded that crystalline silica may cause cancer based on animal data with limited evidence in humans.
