First Aid Measures

General Advice: Remove contaminated clothing and shoes. Seek medical attention if symptoms persist.
Inhalation: Move to fresh air. Seek medical attention for persistent cough or difficulty breathing.
Skin Contact: Wash with plenty of soap and water. Remove contaminated clothing. Seek care for irritation.
Eye Contact: Flush eyes with water for at least 15 minutes, holding eyelids open. Remove contact lenses.
Ingestion: Rinse mouth and drink water, do not induce vomiting. Get medical assistance if significant quantities caused distress.
Note to Physician: Provide symptomatic and supportive treatment. Product is expected to have low toxicity but monitor for respiratory effects.

Fire-Fighting Measures

Suitable Extinguishers: Use water spray, foam, carbon dioxide, or dry chemical powder
Specific Hazards from Combustion: Produces carbon oxides and possibly irritating fumes if burned
Advice for Firefighters: Wear self-contained breathing apparatus and protective gear. Cool containers exposed to fire.
Explosion Risk: Fine dust clouds may ignite; implement dust control measures to avoid rapid flame spread
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, and unidentified organic compounds may form

Accidental Release Measures

Personal Precautions: Avoid breathing dust; ventilate area thoroughly. Wear dust mask, goggles, and gloves.
Environmental Precautions: Prevent release into drains, surface water, and soil. Scoop up spill and avoid dust generation.
Methods for Cleanup: Sweep or vacuum spillage using equipment designed to prevent dust release. Collect in labeled containers; avoid dry sweeping if possible.
Reference to Other Sections: Review handling and personal protection sections for more guidance.

Handling and Storage

Safe Handling: Minimize dust buildup by keeping area clean. Use local exhaust ventilation. Avoid ingestion, avoid contact with eyes, and do not breathe dust.
Storage Conditions: Store in tightly closed containers in a dry, well-ventilated area. Keep away from heat, sources of ignition, and incompatible materials like strong oxidizers.
Special Precautions: Store away from food and beverages. Ground containers and avoid static discharge for bulk quantities. Use only with proper equipment and in accordance with industrial hygiene practices.

Exposure Controls and Personal Protection

Exposure Limits: No occupational exposure limit assigned, but control airborne dust to lowest feasible level
Engineering Controls: Use local and general exhaust. Dust collection systems recommended in processing areas
Personal Protective Equipment:
Eyes: Chemical safety goggles
Skin: Chemical-resistant gloves and protective clothing
Respiratory: NIOSH/MSHA approved dust mask or respirator if exposure may reach nuisance levels
Hygiene Measures: Wash hands and face after working with powder. Remove contaminated clothing promptly. Keep food and beverages away from work area.

Physical and Chemical Properties

Appearance: White crystalline powder (micronized, fine particle size)
Odor: Odorless
Melting Point: 260-270°C
Boiling Point: Not applicable (decomposes before boiling)
Flash Point: Not flammable in bulk; fine powder can support dust explosion at high concentrations
Solubility: Soluble in water and lower alcohols, insoluble in most hydrocarbons
pH: Neutral (5% solution in water)
Vapor Pressure: Negligible
Bulk Density: Approximately 600-900 kg/m³ depending on particle size distribution
Other Properties: Stable under normal conditions, hygroscopic to a limited degree

Stability and Reactivity

Chemical Stability: Stable under recommended transport or storage conditions
Hazardous Reactions: Avoid strong oxidizing agents, acids, and heat sources
Conditions to Avoid: Elevated temperature, open flame, uncontrolled dust clouds
Decomposition Products: Carbon monoxide, carbon dioxide, and other organic fumes if overheated or combusted
Polymerization: Will not occur under normal processing

Toxicological Information

Acute Toxicity: Very low toxicity by ingestion, inhalation, and skin contact
Chronic Effects: Repeated exposure may cause drying or cracking of skin or mild respiratory irritation in sensitive people
Skin/Eye Irritation: Mild, reversible irritation possible with direct exposure
Carcinogenicity: No evidence of carcinogenicity found
Mutagenicity: No evidence from available data
Other Effects: Not known to cause organ damage or reproductive toxicity
Sensitization: No reports of sensitization reactions with normal use

Ecological Information

Ecotoxicity: Not expected to present significant hazard to aquatic or terrestrial life at typical use levels
Persistence and Degradability: Biodegradable, but may persist in soil in large quantities
Bioaccumulation Potential: Does not bioaccumulate
Mobility: Strongly soluble in water, low mobility in soil expected
Other Adverse Effects: Large releases could disrupt aquatic nutrient cycles or cause localized oxygen demand increases
