First Aid Measures

Inhalation: Move to fresh air quickly, monitor for shortness of breath, call for medical help if breathing problems persist
Skin Contact: Remove contaminated clothing, wash exposed skin with warm soapy water for at least 15 minutes, seek medical advice if irritation develops
Eye Contact: Flush with clean running water for at least 15 minutes, hold eyelids apart, remove contact lenses if present and easy to do, get medical support if irritation does not subside
Ingestion: Rinse mouth, do not induce vomiting, never give anything by mouth to someone unconscious, seek immediate medical attention
Notes for Physicians: Treat as an irritant, provide symptomatic support, watch for asthma-like symptoms

Fire-Fighting Measures

Suitable Extinguishing Media: CO2, dry chemical, foam, water spray (avoid direct water jet on burning product)
Specific Hazards: Burning can release toxic gases, including CO, HCN, and nitrogen oxides
Special Protective Equipment: Full protective suit, self-contained breathing apparatus (SCBA)
Advice for Firefighters: Keep containers cool with water spray, prevent run-off from entering drains, ventilate area after extinguishing
Combustion Products: Dense smoke, hydrogen cyanide, isocyanate vapors

Accidental Release Measures

Personal Precautions: Wear appropriate respiratory protection, chemical resistant gloves, goggles or face shield, avoid contact with skin and eyes
Environmental Precautions: Prevent product from entering drains, soil, or watercourses
Methods for Cleaning Up: Absorb spills using inert material like sand or earth, collect with non-sparking tools, place in suitable closed container for disposal
Decontamination: Clean spill area with detergent and water, ventilate room, monitor vapors before access

Handling and Storage

Handling: Use only with adequate ventilation, avoid inhaling vapors or mist, avoid skin and eye contact, wash hands thoroughly after handling, keep containers tightly closed
Storage Conditions: Store in a dry, well-ventilated space at 15–30°C, keep away from direct sunlight, ignition sources, and water
Incompatible Materials: Alcohols, strong bases, amines, water, strong oxidizing agents
Other Precautions: Store only in original containers, use spill containment pallets for bulk storage, rotate stock

Exposure Controls and Personal Protection

Occupational Exposure Limits: Polymeric MDI (TLV-TWA): 0.005 ppm ACGIH
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits
Personal Protective Equipment: Chemical resistant gloves (nitrile, butyl rubber), splash-proof goggles, long-sleeved clothing, impervious boots, NIOSH-approved respirator in areas with poor ventilation
Hygiene Measures: Wash hands and face after work, do not eat or smoke while handling, keep work clothing separate from personal clothing

Toxicological Information

Acute Toxicity: Moderate inhalation and skin toxicity in animal studies, oral LD50 (rat) >5000 mg/kg, inhalation LC50 (rat, 4h) 0.31–0.49 mg/L
Skin Corrosion/Irritation: Causes moderate irritation
Serious Eye Damage/Irritation: Causes pronounced irritation
Respiratory or Skin Sensitization: Potential to cause asthma-like symptoms, can cause allergic dermatitis upon repeated exposure

Carcinogenicity: Not classifiable regarding human carcinogenicity, IARC Group 3
Reproductive Toxicity: No significant effect observed in animal studies
Specific Target Organ Toxicity – Single Exposure: May cause respiratory irritation
Specific Target Organ Toxicity – Repeated Exposure: Potential to cause lung and skin sensitization

Ecological Information

Ecotoxicity: Not readily biodegradable, potentially toxic to aquatic organisms due to slow degradation
Persistence and Degradability: Stable in soil and water, degrades slowly by hydrolysis and microbial action
Bioaccumulative Potential: Low due to high molecular weight, unlikely to significantly bioaccumulate
Mobility in Soil: Immobile, binds to soil and sediment
Other Adverse Effects: Spills may form persistent residues in environment, breakdown products may increase local toxicity

Disposal Considerations

Waste Disposal Methods: Dispose of according to local, regional, national, and international regulations, incinerate only in approved facilities
Container Disposal: Empty containers may retain product residue, follow proper procedures for decontamination and recycling or disposal
Avoid: Discharge to waterways, drains, and soil
Additional Information: Consult licensed waste disposal contractor, ensure responsible management of hazardous substances throughout the disposal chain
