Ref. No. MSDS /PD/18_01 Valid for: 2 years from approval First Aid Measures General measures: Generally not hazardous in normal handling, however good laboratory practices should always be used. Avoid long term exposure to skin or by inhalation. Skin contact: Wash with warm water and mild soap. If irritation occurs, obtain medical advice immediately. Serious skin contact: N/A Eye contact: Holding eyelids open, do not allow victim to rub their eyes. Gently flush eyes for 10 minutes with large quantities of water. Seek medical attention, if irritation develops or persists. Ingestion: Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 8 to 10 ounces (240 to 300 ml) of water to dilute material in stomach. Obtain medical advice immediately. Serious indigestion: N/A Inhalation: Remove to fresh air. Obtain medical advice if required. Serious inhalation: N/A Page 3 of 9 UNIVERSITY OF MALTA FACULTY OF MEDICINE & SURGERY PHARMACY DEPARTMENT MATERIAL SAFETY DATA SHEET CHALK 5. Ref. No. MSDS /PD/18_01 Valid for: 2 years from approval Fire and Explosion Data Flammability of the Product: Non-flammable. Not considered to be a fire hazard. Auto-Ignition Temperature: Not applicable Flash points: Not applicable Flammable limits: Not applicable Products of Combustion: N/A Fire Hazards in Presence of Various Substances: N/A Explosion Hazards in Presence of Various Substances: Not considered to be an explosion hazard. Fire fighting media and Instructions: Use water spray, dry chemical and CO2. Use appropriate extinguishing media for surrounding fire. Special Remarks on Fire Hazards: N/A Special Remarks on Explosion Hazards: N/A 6. Accidental Release Measures NB: Wear appropriate protective equipment/clothing including gloves before removing any spills. Small spill: Spills may be picked up with scoop and absorbent materials, and then transferred to containers. Wear protective clothing and gear during cleanup. Large spill: Use the same procedure as when a small spill occurs. Page 4 of 9 UNIVERSITY OF MALTA FACULTY OF MEDICINE & SURGERY PHARMACY DEPARTMENT MATERIAL SAFETY DATA SHEET CHALK 7. Ref. No. MSDS /PD/18_01 Valid for: 2 years from approval Handling and Storage Precautions: Measures should be taken to minimise and protect against airborne dust during cleanup operations, including use of respiratory protective equipment if necessary. Storage: Store in closed containers in a dry place separate from incompatible materials. 8. Exposure Controls/Personal Protection Airborne Exposure Limits: N/A Engineering Controls: Administrative and/or engineering control methods such as, but not limited to, process enclosure and exhaust ventilation may be necessary to control exposures to dust and/or gaseous organic compounds released at elevated temperatures. Supply sufficient replacement air to make up for air removed by exhaust systems. Selection of all personal protective equipment should be performed by an Industrial Hygienist or other qualified professional. Personal Protection: Gloves (rubber or leather), cotton coveralls, safety goggles and respiratory equipment.

No. MSDS /PD/18_01 Valid for: 2 years from approval Physical and Chemical Properties Physical state and appearance: White solid powder Odour: Odourless Taste: N/A Molecular Weight: N/A pH (1% solution/water): Not applicable Boiling Point: Not applicable Melting Point: 550°C (1022°F) (decomposes) Critical Temperature: Not applicable Specific Gravity (Water = 1): 2.6-2.8 Vapour Pressure (mmHg): Not applicable Vapour Density: Not applicable Volatility: Not applicable Odour Threshold: Not applicable Water/Oil Distribution Coefficient: Not applicable Ionicity (in Water): Not applicable Dispersion Properties: Not applicable Solubility: 1.3 mg/100 g @ 18°C 10. Stability and Reactivity Data Stability: Stable under ordinary conditions of use and storage. Corrosivity: N/A Instability temperature: Thermal decomposition of limestone beginning at 550°C (1022°F) can produce calcium oxide and carbon dioxide. Heating of this product above 244°C (471°F) may cause volatilization and/or thermal decomposition of processing aids, resulting in the gaseous release of trace amounts of organic compounds. Conditions of Instability: Incompatible materials and excessive temperatures. Incompatibles: Reacts with acids to liberate carbon dioxide. Ignites on contact with fluorine. Also incompatible with alum and ammonium salts. Polymerization: Will not occur Page 6 of 9 UNIVERSITY OF MALTA FACULTY OF MEDICINE & SURGERY PHARMACY DEPARTMENT MATERIAL SAFETY DATA SHEET CHALK 11. Ref. No. MSDS /PD/18_01 Valid for: 2 years from approval Toxicological Information Toxicity to animals: N/A Effects on humans: Acute potential health effects: Inhalation: Dust may irritate the respiratory tract. Symptoms include sneezing and slight nose irritation. Ingestion: Ingestion of very large quantities may result in intestinal obstruction and/or constipation. Skin: Repeated or prolonged exposure may have a drying effect on the skin, and may also cause irritation. Eye: Irritation. Symptoms include watering and irritation. Chronic potential health effects: 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.
