Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry powder, foam, carbon dioxide
Unsuitable Extinguishing Media: Straight water streams may scatter dust
Special Hazards: Decomposition releases hydrogen chloride, carbon monoxide, and possible traces of phosgene at elevated temperatures
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective clothing
Fire/Explosion Hazards: Dust accumulation can form explosive mixtures in air, handle to minimize dust
Thermal Decomposition Products: HCl, CO, small amounts phosgene at very high temperature
Specific Methods: Isolate area if possible, cool containers exposed to fire with water

Accidental Release Measures

Personal Precautions: Do not breathe dust, avoid contact with skin and eyes
Protective Equipment: Use personal protective equipment including dust mask, goggles, and gloves
Environmental Precautions: Prevent entry into drains, sewers, waterways, and soil
Cleanup Methods: Sweep or vacuum up material avoiding dust generation, transfer to sealed container for recovery or disposal
Spillage: Damp down material with water spray to reduce dust
Disposal: Dispose of recovered material following local, regional, or national regulatory requirements

Handling and Storage

Handling: Avoid generating dust, employ local exhaust ventilation where possible, do not eat or drink while handling, wash hands thoroughly after use
Storage: Store in original containers tightly closed, in a cool, dry, well-ventilated area away from incompatible materials
Incompatible Materials: Strong oxidizing agents, strong acids and alkalis
Conditions to Avoid: High humidity, direct sunlight, strong heat sources
Specific Requirements: Use grounding and bonding to prevent static discharge where dust may accumulate
Packaging: Use containers designed for chemical storage, keep sealed when not in use

Exposure Controls and Personal Protection

Exposure Limits: No occupational exposure limits established for copolymer; monitor dust using general nuisance particulate threshold values (ACGIH TLV: 10 mg/m³ for inhalable dust, 3 mg/m³ for respirable dust)
Engineering Controls: Use process enclosures, local exhaust ventilation to control airborne dust
Personal Protective Equipment: Safety glasses or goggles, chemical-resistant gloves, dust mask (P2 or N95), protective clothing recommended for bulk handling
Hygiene Measures: Wash hands and exposed skin after handling, remove contaminated clothing before breaks
Environmental Controls: Use closed handling systems where feasible, prevent dust release into environment, collect spilled material promptly
