Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses; seek medical attention if redness or irritation persists
Skin Contact: Wash skin with soap and water; discontinue exposure; seek help for persistent reactions
Inhalation: Move person to fresh air; provide oxygen or artificial respiration if breathing is difficult; get medical help for ongoing symptoms
Ingestion: Rinse mouth; do not induce vomiting; consult physician or poison control for guidance, especially if symptoms appear
Suitable Extinguishing Media: Water spray, foam, carbon dioxide, dry chemical
Unsuitable Media: Strong water jet for large fires, as dispersion may occur
Fire Hazards: Product can form combustible dust-air mixtures; combustion produces carbon oxides
Protective Equipment: Firefighters should wear positive pressure self-contained breathing apparatus and protective clothing to protect skin and eyes from contact
Specific Methods: Use water spray to keep fire-exposed containers cool; prevent runoff from entering drains or waterways
Personal Precautions: Use personal protection including goggles, gloves, and dust mask; ventilate area
Environmental Precautions: Prevent entry into sewers, drains, and waterways by containing spill
Methods for Cleaning Up: Sweep or vacuum material to avoid creating dust; collect in suitable container for reclamation or disposal; wash spill site with soap and water after pickup completed
Handling: Minimize dust generation and accumulation; use in well-ventilated area; avoid breathing dust and contact with eyes or skin; wash hands after use
Storage: Store in tightly closed container; keep in a cool, dry, well-ventilated space; store away from strong oxidizers, acids, and heat sources
Incompatible Materials: Avoid contact with strong acids, oxidizing agents, and bases for product longevity
Occupational Exposure Limits: Not established for this compound
Engineering Controls: Use general or local exhaust ventilation to maintain airborne levels below dust exposure guidelines
Personal Protective Equipment: Safety glasses, gloves, and dust respirator as situation warrants
