Hazard Identification

Classification: Not classified as hazardous under GHS
Signal Word: Not required
Hazard Statements: May cause mild irritation to eyes, skin, or respiratory tract
Precautionary Statements: Avoid contact with eyes, avoid inhaling dust, wash hands after handling
Potential Health Effects: Inhalation of dust may lead to throat or nasal discomfort; eye contact can produce mild irritation; skin staining possible with prolonged exposure; ingestion in large amounts not recommended, causes laxative effects
Environmental Hazards: Material does not readily pose an environmental hazard but good practice encourages preventing release into environment

Composition / Information on Ingredients

Chemical Name: Saccharin Calcium, Trihydrate
Concentration: 98-102% (as per food grade standards)
Impurities: Small traces of related saccharin compounds, water, possible sodium contaminants in trace amounts
Other Ingredients: No additional additives or dangerous inert ingredients reported in standard grade

First Aid Measures

Inhalation: Move affected person to fresh air. Respiratory discomfort usually subsides quickly. Medical attention recommended for persistent symptoms.
Skin Contact: Wash exposed areas thoroughly with soap and water. Remove contaminated clothing. Mild irritation may occur with prolonged contact.
Eye Contact: Rinse eyes with water for at least 15 minutes, keeping eyelids open. Seek medical advice if redness or discomfort persists.
Ingestion: Rinse mouth and give water to drink if conscious. Do not induce vomiting unless instructed by a medical professional. Medical attention required for large amounts or gastrointestinal distress.
Note to Physician: Treat symptoms and provide supportive care. Allergic reactions rare and generally associated with high exposures.

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: None known for product itself
Specific Hazards: Product is not flammable. Heated material may decompose to produce sulfur oxides and nitrogen oxides
Protective Equipment and Precautions for Firefighters: Wear self-contained breathing apparatus and standard protective gear. Avoid inhalation of fumes from burning product. Runoff from firefighting may be mildly alkaline or contain dissolved solid.

Accidental Release Measures

Personal Precautions: Use dust mask, protective goggles, gloves. Ventilate area to disperse dust
Environmental Precautions: Prevent spills from entering waterways, sewer, or soil surfaces.
Methods for Cleaning Up: Sweep up material and collect in labeled containers for reuse or disposal. Residue can be washed away with plenty of water. For large quantities, use non-sparking tools.

Handling and Storage

Handling: Minimize dust generation. Use clean, dry utensils or equipment. Wash hands after handling.
Storage Conditions: Store in a cool, dry, and well-ventilated area. Keep container tightly closed and labeled. Avoid moisture exposure to prevent clumping and spoilage. Protect from strong acids and bases.
Incompatible Materials: Avoid strong acids, strong bases, oxidizing agents which may cause decomposition or hazardous reactions.
Packing Materials: Use original containers or compatible plastics; metal containers generally acceptable.

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established regulatory limits worldwide for saccharin calcium dust.
Engineering Controls: Employ local exhaust ventilation, especially for bulk material transfer or prolonged handling.
Personal Protective Equipment: Dust mask (P2 or N95 standard), safety goggles, nitrile gloves, laboratory coat or apron.
Hygiene Measures: Do not eat, drink, smoke while handling material. Wash hands and face before breaks and at end of shift.

Physical and Chemical Properties

Stability and Reactivity

Chemical Stability: Stable under normal temperatures, pressures, dry conditions
Possibility of Hazardous Reactions: Contact with strong oxidizers may cause exothermic reaction; strong acids and bases accelerate hydrolysis
Conditions to Avoid: Excess moisture, high heat, direct sunlight, proximity to reactive chemicals
Incompatible Materials: Concentrated acids, alkalis, strong oxidizing/reducing agents

Irritation: Eyes and skin may show slight irritation; not classified as a sensitizer
Chronic Effects: No evidence of carcinogenic, teratogenic, or mutagenic effects at typical dietary levels
Routes of Exposure: Inhalation, ingestion, dermal, ocular
Symptoms: High dust exposure leads to coughing, sneezing, possible sore throat; ingestion in large amounts causes mild gastrointestinal discomfort
Carcinogenicity: No listing in IARC, NTP, OSHA as carcinogen. Regulatory reviews show low concern for cancer at current human exposures.
Other Health Effects: No evidence for reproductive toxicity, no known major target organ toxicity

Ecological Information

Mobility in Soil: Readily soluble; can move through moist soils but rapidly diluted and degraded
Other Adverse Effects: No evidence for significant environmental risk based on present use patterns

Disposal Considerations

Product Disposal: Small amounts can be disposed of with normal solid waste; large amounts should go through a licensed chemical waste contractor or as per local disposal requirements.
