SECTION 4 - FIRE & EXPLOSION DATA
| Flash Point: Extinguishing Media: Special Fire Fighting Procedures: Unusual Fire & Explosion Hazards: |
Non-Flammable. Not Applicable. None. None. |
SECTION 5 – REACTIVITY DATA
| Stability: Reactivity in Water: |
Stable. None. |
| Incompatibility (Material to Avoid): | Reacts with acids and liberates carbon dioxide. Ignites on contact with fluorine. Also incompatible with alum and ammonium salts. |
| Hazardous Polymerization: Hazardous Decomposition Products: |
Will not occur. Thermal decomposition can produce calcium oxide and carbon dioxide. |
SECTION 6 – TOXILOGICAL PROPERTIES
EFFECTS AND HAZARDS OF ACUTE EXPOSURE:
| Inhalation: | Dust may irritate the respiratory tract. Symptoms include sneezing and slight nose irritation. |
| Eye Contact: | Irritation. Symptoms include watering and irritation. |
| Skin Contact: | Repeated or prolonged exposure may have a drying effect on the skin, and may also cause irritation. |
| Ingestion: | Ingestion of very large quantities may result in intestinal obstruction and/or constipation. |
| EFFECTS AND HAZARDS OF CHRONIC EXPOSURE: | |
| Chronic exposure to limestone dust at concentrations exceeding occupational exposure limits may cause pneumoconiosis (lung disease). This product contains crystalline silica (quartz) as an impurity. Chronic exposure to crystalline silica dust at concentrations exceeding occupational exposure limits may cause silicosis. The NTP’s Ninth Report on Carcinogens lists crystalline silica (respirable size) as a known human carcinogen. IARC concluded that there is sufficient evidence in humans for the carcinogenicity of inhaled (respirable) crystalline silica. | |
SECTION 7 – FIRST AID MEASURES
| Eye Contact: | Flush thoroughly with water. If irritation persists, seek medical attention. |
| Skin Contact: | Wash with mild soap and warm water. |
| Inhalation: | Remove to fresh air. Obtain medical advice if required. |
| Ingestion: |
Never give anything by mouth if victim is rapidly losing consciousness or is unconscious or convulsing. Rinse mouth thoroughly with water. Do not induce vomiting. Drink 8 to 10 ounces (240 to 300 ml)of water to dilute material in stomach. Obtain medical advice immediately. |
SECTION 8 – PREVENTATIVE MEASURES
| Spills/Leaks: | Measures should be taken to minimize and protect against airborne dust during cleanup operations, including use of respiratory protective equipment if necessary. |
| Disposal: | From a waste perspective, this product is not considered hazardous and may be disposed of as solid waste in accordance with applicable federal, state, provincial, and local regulations. |
| Handling: | Administrative and/or engineering control methods such as, but not limited to, process enclosure and exhaust ventilation may be necessary to control dust exposures. Supply sufficient replacement air to make up for air removed by exhaust systems. If engineering controls and work practices are not effective in controlling exposures, appropriate personal protective equipment including a NIOSH/OSHA approved dust respirator should be worn. Appropriate eye protection should be worn. Selection of all personal protective equipment should be performed by an Industrial Hygienist or other qualified professional. |

SECTION 9 –REGULATORY INFORMATION
| TSCA: | This product primarily is natural calcium carbonate from limestone ore which is listed on the U.S. EPA TSCA inventory under Limestone, CAS# 1317-65-3. In addition, all other ingredients and/or processing aids are also on the TSCA inventory. |
| DSL: | BY virtue of its status as a “substance occurring in nature”, ground limestone is considered to be on the Canadian Domestic Substances List. In addition, all other ingredients and/or processing aids are also on the DSL. |
| CONEG: | Being derived from limestone ore, this product may contain incidental trace levels of naturally occurring metals. However, no metals are intentionally added and this product complies with the CONEG requirement of <100 ppm of Cd, Cr+6, Pb, and Hg. |
| ODCs: | This product does not contain, nor is it produced with, any U.S. EPA-defined Class I or Class II ozone-depleting chemicals. |
| FDA: | This product may be used as an indirect food additive in food packaging applications under 21 CFR (FDA) 174.5, 175.300, and 178.3297. It does not qualify as a substance permitted for direct addition to human food or animal feed. |
