First Aid Measures

Inhalation: Remove to fresh air; seek medical attention if symptoms develop
Skin Contact: Wash with soap and water, remove contaminated clothing, treat thermal burns with cold water if molten product contacted skin, get medical attention for burns
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, lift eyelids to ensure thorough flushing, seek medical attention if irritation persists
Ingestion: Rinse mouth with water, do not induce vomiting, seek medical advice if significant quantity swallowed; unlikely to be toxic by ingestion

Fire-Fighting Measures

Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray (use water spray to cool containers)
Unsuitable Media: Direct streams of water may spread burning material
Specific Hazards: Combustible dust, may form explosive mixtures with air, hot product may splatter when contacted by water
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, acetic acid, smoke
Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective clothing

Accidental Release Measures

Personal Precautions: Use protective equipment to avoid dust inhalation and skin contact, ensure adequate ventilation, eliminate all ignition sources
Environmental Precautions: Prevent spillage from entering drains or watercourses
Methods for Clean Up: Sweep up material, place in appropriate waste container, use vacuum systems for dust, wash spill area with water if permitted by regulations

Handling and Storage

Handling: Avoid generating dust, use local exhaust ventilation, prevent static discharge by grounding all equipment, avoid contact with molten product
Storage Conditions: Store in a cool, dry, well-ventilated area away from heat or ignition sources, keep container tightly closed, protect from moisture

Exposure Controls and Personal Protection

Exposure Limits: None established specifically for Ester Gum; control dust levels below nuisance dust limits (OSHA PEL: 15 mg/m³ total, 5 mg/m³ respirable)
Engineering Controls: Use mechanical ventilation to control dust concentrations, process enclosures recommended for dusty operations
Personal Protective Equipment:
Respiratory Protection: NIOSH-approved dust mask for dusty environments
Eye Protection: Safety glasses with side shields
Skin Protection: Gloves resistant to thermal burns, protective sleeves where contact with molten product can occur
General Hygiene: Wash thoroughly after handling, remove and launder contaminated clothing
