Hazardous Components: This product contains no components classified as hazardous under present legislation
Inhalation: Move individual to fresh air; seek medical attention for persistent irritation or discomfort
Skin Contact: Wash exposed skin with soap and water; seek medical advice for rash or persistent discomfort
Eye Contact: Rinse eyes cautiously with water for at least 15 minutes; remove contact lenses if present and easy to do; consult doctor if irritation continues
Ingestion: Rinse mouth with water; drink water to dilute; seek medical help for large amounts swallowed or if feeling unwell
Symptoms/Effects: Dust exposure might cause mild respiratory or eye irritation, especially in poorly ventilated spaces
Suitable Extinguishing Media: Carbon dioxide, dry chemical, foam, water spray
Unsuitable Extinguishing Media: High-pressure water jets may spread burning dust
Special Hazards: Emits carbon oxides when burned; avoid inhaling combustion products
Protective Equipment: Firefighters require self-contained breathing apparatus and full protective gear
Fire/Explosion Hazards: Product is not combustible under typical conditions; dust may form explosive mixtures with air under rare circumstances
Advice for Firefighters: Stay upwind, remove containers from fire area if safe, limit run-off with containment
Personal Precautions: Avoid breathing dust; ventilate area; wear protective clothing, gloves, and eye protection
Environmental Precautions: Avoid discharge to drains, surface or groundwater
Spill Cleanup Methods: Scoop or sweep up spilled material carefully; avoid raising dust; collect in suitable, labeled containers
Reference to Other Sections: Refer to sections on exposure controls and personal protection for more advice on workplace safety
Handling: Avoid dust creation; use local exhaust where dust is generated; wash hands before eating, drinking, or smoking
Hygiene Measures: Keep work areas clean; wash exposed skin before breaks and after finishing work
Storage Conditions: Store in a tightly closed container in a cool, dry, well-ventilated area; keep out of reach of children
Incompatibilities: Avoid contact with strong oxidizing agents or acids
Safe Packaging Materials: Use original packaging or compatible containers that keep contents dry and free from contamination
Control Parameters: No occupational exposure limits established for this compound
Engineering Controls: Use extraction or local ventilation where handling routine creates dust
Respiratory Protection: Dust mask or respirator may be appropriate in dusty conditions
Eye Protection: Safety glasses with side shields or chemical goggles if dust likely
Skin Protection: Gloves recommended when handling bulk product; lab coats or long-sleeve clothing reduce skin contact
Work Practices: Remove contaminated clothing; wash hands thoroughly after handling

Conditions to Avoid: Excessive heat, moisture, open flames, and strong oxidizers
Incompatible Materials: Strong oxidizing agents, acids
Hazardous Decomposition: Releases carbon oxides and calcium oxide at high temperatures
Polymerization: Will not occur
Other Information: Exposure to light or air over time could decrease potency but does not create a new hazard
Likely Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: LD50 (oral, rat) > 5000 mg/kg (essentially non-toxic)
Skin Corrosion/Irritation: Mild irritation possible for sensitive individuals
Serious Eye Damage/Irritation: May cause slight mechanical eye irritation, especially in powder form
Respiratory Sensitization: Dust may cause temporary irritation
Carcinogenicity: Not recognized as carcinogenic by IARC, NTP, or OSHA
Reproductive Toxicity: No evidence or indication of reproductive harm at dietary exposures
Repeated Dose Toxicity: High amounts over extended periods may affect kidney function due to calcium burden, but not at commonly used doses
Symptoms: Occasional mild gastrointestinal upset if unusually high amounts are consumed
Ecotoxicity: Not anticipated to be harmful to aquatic or terrestrial organisms at normal levels
Persistence and Degradability: Degrades naturally in the environment, mainly by oxidation
Bioaccumulation Potential: Low, given rapid metabolism and natural occurrence
Mobility in Soil: Readily soluble in water; will partition to soil moisture
Other Adverse Effects: No known endocrine disrupting effects or long-term hazards at realistic exposures
Precaution for Environment: Avoid unnecessary release to surface waters to limit nutrient load and water clouding
