General Advice: Remove affected individual from exposure; seek medical attention for persistent irritation
Inhalation: Move to fresh air. Support breathing; rinse mouth if discomfort persists. No anticipated severe effects
Skin Contact: Wash affected area thoroughly with soap and water. Remove contaminated clothing if irritation develops
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes. Seek medical evaluation for persistent redness
Ingestion: Rinse mouth. Drink water to dilute. No medical treatment expected for minor amounts. Consult physician if symptoms appear
Note to Physician: Symptomatic treatment as required. No specific antidote reported
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, water mist. Avoid streaming large amounts of water which may spread molten material
Specific Hazards: Fine powder in air can form explosive mixtures. Thermal decomposition releases minor amounts of carbon oxides, acrolein, and organic acids
Special Protective Equipment: Firefighters should wear approved self-contained breathing apparatus and protective clothing in enclosed areas
Flammability Class: Not classified as highly flammable; combustibility rises with dust or if mixed with other organic powders
Fire-Fighting Procedures: Move containers from fire area if safe. Cool down closed containers with water, prevent run-off into water systems
Personal Precautions: Avoid breathing dust. Use personal protective equipment to prevent skin or eye contact
Protective Equipment: Dust mask or particulate respirator, goggles, gloves, industrial coveralls
Spill Response: Contain spilled product. Avoid dust formation; sweep up and shovel into suitable container for proper disposal
Environmental Precautions: Prevent large spills entering sewers and natural waterways, as material may impact aquatic oxygen levels in bulk
Methods for Cleanup: Dampen dusty material to prevent dispersal. Collect residue, ventilate area
Safe Handling: Use in well-ventilated area. Minimize dust generation and accumulation. Handle in accordance with good industrial hygiene and safety practice
Hygiene Practices: Wash hands after handling. Do not eat, drink, or smoke during use
Storage Conditions: Store tightly sealed in cool, dry, well-ventilated area. Protect from extreme heat, direct sunlight, ignition sources
Storage Incompatibilities: Keep away from strong oxidizers, moisture, acids, alkalis. Store food-grade product separately from industrial chemicals
Special Requirements: Ensure storage vessels are labeled and compatible (plastic, stainless steel recommended)
Occupational Exposure Limits: No established TLV/TWA; keep airborne dust below nuisance dust levels (typically 10 mg/m³ for total dust)
Engineering Controls: Local exhaust ventilation to control dust. Enclosed processing recommended for high-volume applications
Personal Protective Equipment: Dust-filtering respirator, chemical splash goggles, gloves (nitrile or latex), protective clothing if risk of contact exists
Workplace Hygiene: Change and wash clothing after handling; maintain good personal hygiene practices
Environmental Controls: Routine air monitoring for dust in large-scale manufacturing or packaging shops
Appearance: White to pale yellow waxy solid, flakes, beads, or powder
