Other Components: Product offered as a single substance, no solvents or excipients present
Inhalation: Move exposed individual to fresh air, provide comfortable position, seek medical attention if coughing or difficulty in breathing develops
Skin Contact: Remove contaminated clothing and gently wash with soap and water for several minutes—note any persistent irritation and contact medical personnel
Eye Contact: Rinse slowly and gently with clean water for at least 15 minutes; avoid vigorous rubbing, remove contact lenses if present and easy to do, obtain further medical review if symptoms persist
Ingestion: Rinse mouth, offer water to drink, avoid inducing vomiting, monitor for symptoms and consult physician if discomfort or adverse effects arise
Extinguishing Media: Water spray, carbon dioxide, dry chemical powder, or foam to cool fire-exposed containers
Hazardous Combustion Products: May generate nitrogen oxides, sulfur oxides, carbon monoxide/dioxide, hydrochloric acid fumes upon burning
Protective Equipment: Firefighters require self-contained breathing apparatus and full protective gear
Special Procedures: Move containers from fire area if it can be done without risk, avoid inhaling vapors, cool surfaces with water spray to prevent pressure build-up
Unusual Fire Hazards: Dust may form explosive mixtures with air; minimize dust dispersal
Personal Precautions: Avoid generating dust, ventilate area, use respiratory protection if dust exposure possible
Environmental Precautions: Keep product out of water supplies, sewers, and soil; large spills call authorities for support
Spill Cleanup Methods: Sweep up material using non-sparking tools, place in clean, dry, labeled container for proper disposal
Decontamination: Wash spill area with water and mild detergent, avoid excessive water use to prevent unnecessary runoff
Handling Advice: Handle with care; use appropriate personal protective equipment including gloves and safety glasses; avoid eating or drinking while using this product; good laboratory practice includes minimizing dust generation through attentive technique
Storage Conditions: Store in tightly closed container, away from direct sunlight, heat, and moisture; place containers in cool, dry, well-ventilated area with clear labeling
Incompatible Materials: Strong oxidizing agents, reducing agents, bases
Special Considerations: Avoid contamination; assign dedicated utensils and equipment if using in pharmaceutical contexts
Engineering Controls: Use in vented area or fume hood, avoid open containers where dust may spread; fit local exhaust as needed
Respiratory Protection: Wear approved dust masks or respirators when handling large quantities or in poorly ventilated areas
Skin Protection: Wear chemical-resistant gloves (nitrile, latex), lab coat or apron
Eye Protection: Safety goggles or glasses meeting local standards
Other Protection: Wash hands thoroughly after use; avoid touching face, eyes, or mouth; remove contaminated clothing promptly
