Substance/Preparation: Substance
Inhalation: Remove person to fresh air, rinse mouth and nose with water, keep calm; seek medical attention if coughing or breathing difficulty persists
Eye Contact: Rinse thoroughly with water for several minutes, hold eyelids open, remove contact lenses if present and easy to do; do not rub eyes
Skin Contact: Wash skin with soap and water, remove contaminated clothing, seek attention for persistent irritation
Ingestion: Rinse mouth with water, drink plenty of water, avoid inducing vomiting, consult medical professional if feeling unwell
Specific Treatments: Symptomatic treatment only, no antidote required for dust exposure at normal handling levels
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Unsuitable Extinguishing Media: High-pressure water jet (risk of dust dispersion)
Specific Hazards: Dust clouds may ignite and cause explosion in confined areas, may emit carbon monoxide and carbon dioxide during combustion
Advice for Firefighters: Wear full protective equipment, self-contained breathing apparatus; stay upwind
Firefighting Precautions: Move containers from fire area if safe, prevent fire-fighting water from entering drains or watercourses
Personal Precautions: Avoid breathing dust, use protective mask and eyewear, ventilate area
Environmental Precautions: Prevent spillage from entering drains, water courses, and soil
Containment Methods: Contain spillage using non-flammable inert material (such as sand), avoid generating dust clouds
Cleanup Methods: Sweep or vacuum up (with equipment designed for explosive dusts) and transfer to appropriate labeled waste containers for disposal
Decontamination: Wash area with water after removal, minimize further dust release
Handling: Avoid raising and breathing dust, use local exhaust ventilation, ground equipment to prevent static discharge; avoid sources of ignition
Storage: Store in tightly sealed containers, in cool, dry, well-ventilated area, away from oxidizing agents and moisture, keep away from heat and open flame
Incompatible Materials: Strong oxidants, concentrated acids
Special Packaging: Use moisture-proof, anti-static packaging for bulk transport
General Hygiene: Wash hands after handling, do not eat or drink in handling areas, clean clothing frequently
Control Parameters: No specific occupational exposure limit established; typical dust (inhalable): 10 mg/m3 (ACGIH TLV for nuisance dust)
Engineering Controls: Local exhaust ventilation, dust collection, explosion-proof electrical installation in high dust areas
Personal Protective Equipment: Safety goggles, dust mask or respirator (P2 or N95 recommended), gloves for sensitive skin, protective clothing if splashing likely
Environmental Controls: Prevent dust release into environment, regular housekeeping of work area
