First Aid Measures

Inhalation: Move person to fresh air away from exposure. If breathing is difficult, provide oxygen and contact medical personnel.
Skin Contact: Remove contaminated clothing and wash skin thoroughly with soap and water. If itching, redness, or irritation develop, get medical attention.
Eye Contact: Rinse cautiously with water for several minutes, lifting eyelids. Remove contact lenses if present and easy. Continue rinsing and seek medical attention if discomfort persists.
Ingestion: Rinse mouth with water. Do not induce vomiting. Get medical help if feeling unwell or symptoms such as nausea and abdominal pain occur.

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical, foam, carbon dioxide, or water spray.
Unsuitable Extinguishing Media: Direct water jets may spread burning material.
Specific Hazards: Product may emit toxic fumes under fire conditions, including carbon monoxide, nitrogen oxides, and cyanide compounds.
Protective Equipment: Firefighters wear self-contained breathing apparatus and full protective clothing.
Special Procedures: Control runoff to prevent contamination of sewers and waterways.

Accidental Release Measures

Personal Precautions: Evacuate area if large spill. Use personal protective equipment including gloves, goggles, and approved respiratory protection.
Methods for Cleaning Up: Sweep up and place material in a properly labeled waste container. Avoid generation of dust. Ventilate affected area.
Environmental Precautions: Prevent entry into soil, drains, and surface waters. Report significant spills to appropriate authorities.

Handling and Storage

Handling: Work in well-ventilated area. Avoid contact with skin and eyes and prevent dust formation. Use only with proper protective equipment.
Storage: Store tightly closed in cool, dry and well-ventilated area away from heat sources, direct sunlight, moisture, and incompatible materials like strong oxidizers and acids. Keep out of reach of children and unauthorized personnel.

Exposure Controls and Personal Protection

Exposure Limits: No specific exposure limits set for TAIC; monitor for nuisance dust as recommended by local regulations.
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended limits.
Personal Protective Equipment: Wear chemical-resistant gloves, safety goggles, and protective clothing. Use NIOSH-approved respirators for dust or aerosol exposure.
Hygiene Measures: Wash hands and face after handling. Do not eat, drink, or smoke in work areas.

Toxicological Information

Acute Toxicity: Oral LD50 (rat) >5000 mg/kg (low toxicity)
Skin Corrosion/Irritation: May cause mild to moderate skin irritation, especially with prolonged contact
Eye Damage/Irritation: Causes eye irritation
Respiratory Sensitization: May cause irritation to respiratory tract if inhaled as dust
Skin Sensitization: May cause allergic reactions with repeated contact
Chronic Effects: Repeated or prolonged exposure may affect kidney or liver function.
Carcinogenicity/Mutagenicity: No definitive data for carcinogenicity or mutagenicity in humans

Ecological Information

Toxicity to Aquatic Life: Low acute toxicity expected for fish and daphnia; limited water solubility.
Persistence and Degradability: Biodegradability is limited under environmental conditions; breaks down slowly.
Bioaccumulative Potential: Potential for bioaccumulation is considered low.
Mobility in Soil: Slightly mobile in soil due to low solubility.
Other Hazards: Avoid release into the environment due to slow degradation.

Disposal Considerations

Waste Treatment Methods: Dispose of contents and container by incineration or landfill at licensed facility following local and national regulations.
Product: Avoid discharge to sewers and surface waters.
Contaminated Packaging: Rinse thoroughly, then recycle or dispose of as hazardous waste if contaminated.
