First Aid Measures

Inhalation: Move person to fresh air; seek medical attention for persistent cough or difficulty breathing
Skin Contact: Wash skin with soap and plenty of water; if molten material contacts skin, cool with cold water, do not try to remove solidified material and get medical help
Eye Contact: Rinse with plenty of water for at least 15 minutes; remove contact lenses and continue rinsing; seek help if irritation remains
Ingestion: Rinse mouth, do not induce vomiting; seek medical advice
Additional Information: Show safety data sheet to physician if available

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, or water spray
Unsuitable Media: Direct water jet may spread molten polymer
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, acetic acid, aldehydes, volatile organic compounds
Protective Equipment: Self-contained breathing apparatus (SCBA) and full protective clothing
Fire Hazards: Polymer melts and drips; burning material can produce dense, irritating smoke
Special Procedures: Remove combustibles from area, cool adjacent containers with water spray

Accidental Release Measures

Personal Precautions: Avoid breathing dust or fumes; avoid eye and skin contact
Protective Equipment: Wear gloves, goggles, dust mask or respirator if dust or fumes are present
Spill Cleanup Methods: Sweep or vacuum spillage for recovery or disposal; avoid raising dust
Environmental Precautions: Prevent entry into waterways or drains; avoid soil contamination
Waste Disposal: Place in appropriate waste container for recycling or landfill disposal as per regulations

Handling and Storage

Safe Handling: Avoid generation of dust and inhalation of processing fumes;
use local exhaust ventilation; prevent static charge buildup
Storage Conditions: Store in a cool, dry, well-ventilated space away from strong oxidizers
Packaging Materials: Use containers that keep product dry and protected from contamination
Temperature Limits: Do not store near heat sources; avoid excessive temperatures above 40°C
Handling Precautions: Use grounded equipment; minimize rough handling to decrease dust generation

Exposure Controls and Personal Protection

Occupational Exposure Limits: No official OSHA PEL or ACGIH TLV for EVA; observe nuisance dust limits (15 mg/m³ total dust, 5 mg/m³ respirable fraction)
Engineering Controls: Use local exhaust during processing; general ventilation for storage areas
Personal Protective Equipment: - Eye Protection: Safety glasses or goggles - Skin Protection: Gloves when handling hot or molten material - Respiratory Protection: Dust mask for handling powders; respirator for fume exposure
Hygiene Measures: Wash hands after handling; remove contaminated clothing before eating
