Eye Contact: Rinse cautiously with water for several minutes, consult a doctor if redness or pain lasts
Ingestion: Rinse mouth, seek medical attention if symptoms develop
Acute and Delayed Symptoms: Mechanical irritation only; no chronic toxicity expected

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Combustion Products: Carbon monoxide, carbon dioxide, hydrogen cyanide, acrylic monomers
Protective Equipment: Self-contained breathing apparatus for firefighters
Special Precautions: Avoid inhaling smoke or fumes from burning rubber, remain upwind
Flammability: Solid burns if strongly heated

Accidental Release Measures

Personal Precautions: Wear appropriate gloves, dust mask if dust is generated
Spill Cleanup: Gather mechanically, sweep or vacuum, dispose according to local rules
Environmental Precautions: Prevent large amounts from entering waterways
Methods for Containment: Collect spilled material, avoid generating dust

Handling and Storage

Handling: Use only with adequate ventilation, avoid dust and fumes, wash hands after use
Storage Conditions: Store in cool, dry, well-ventilated place away from heat, open flames, oxidizers
