CAS Number: 113875-40-8
Concentration: Greater than 98 percent pure
Impurities: Trace organic and inorganic impurities, proprietary but typically under 2 percent
Additives: Contains no additional preservatives, coloring, or stabilizers
Inhalation: Move person to fresh air; seek medical attention if symptoms persist like coughing or shortness of breath
Skin Contact: Remove contaminated clothing immediately; wash affected area thoroughly with soap and water for at least 15 minutes; monitor for symptoms of irritation
Eye Contact: Rinse carefully with plenty of water for 15 minutes, lifting eyelids occasionally; seek medical attention if redness or pain continues
Ingestion: Rinse mouth with water; do not induce vomiting unless directed by a medical professional; seek medical attention if symptoms develop
Notes to Physician: Treat symptomatically; consider local irritation and recommend supportive care
Suitable Extinguishing Media: Dry chemical, carbon dioxide, water spray, or alcohol-resistant foam
Specific Hazards: May release toxic or irritating fumes under fire conditions, such as sulfur oxides, nitrogen oxides, and sodium oxide
Protective Equipment: Use self-contained breathing apparatus and full protective gear
Special Procedures: Use water spray to cool fire-exposed containers; avoid contamination of water sources used for firefighting
Combustion Products: Combustion can create hazardous gases, so avoid inhaling fumes generated by fire
Personal Precautions: Wear gloves, safety goggles, and dust mask or respirator; ventilate area to prevent dust accumulation
Environmental Precautions: Avoid release into sewers, soil, or waterways; contain spillage where possible
Containment: Sweep up material with minimal dust generation; use inert absorbent material if mixed with liquids
Cleanup: Place collected material in closed, labeled containers for disposal according to regulations
Decontamination: Wash affected area with copious water after material removal
Handling: Use with adequate ventilation; keep container tightly sealed when not in use; avoid breathing dust or direct contact with skin and eyes
Storage Conditions: Store in a cool, dry, well-ventilated place; keep away from direct sunlight, moisture, and incompatible substances such as strong acids and oxidizers
Packaging: Store in tightly closed containers made of compatible material, preferably polyethylene or glass
Hygiene Practices: Wash hands thoroughly after handling; do not eat, drink, or smoke in work area; clean work clothing regularly
Incompatible Materials: Strong oxidizing agents, strong acids
Engineering Controls: Use local exhaust ventilation or process enclosures to minimize airborne dust; safety shower and eyewash station should be nearby
Respiratory Protection: In conditions of dust formation, wear suitable respiratory protection (N95 or equivalent)
Skin Protection: Wear protective gloves resistant to chemical exposure; use a lab coat or suitable clothing
Eye Protection: Use safety goggles or face shield if risk of splashing exists
