Concentration: >95% (neat compound), up to 5% organic and inorganic byproducts
Eye Contact: Immediately flush with plenty of water for at least 15 minutes. Remove contact lenses, continue rinsing. Seek medical attention.
Skin Contact: Remove contaminated clothing. Wash skin using water and soap. Call physician if irritation develops.
Inhalation: Move to fresh air. Seek medical advice if cough, shortness of breath, or discomfort persist.
Ingestion: Rinse mouth thoroughly, do not induce vomiting unless directed by medical personnel. Consult a physician promptly.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, water spray
Special Hazards: Combustion produces oxides of carbon, sulfur oxides, phosphorus-containing gases; run-off may pollute waterways
Protective Equipment: Firefighters must use self-contained breathing apparatus and full protective gear
Advice: Remove containers from fire area if safe to do so. Cool exposed containers with water fog.
Personal Precautions: Wear chemical-resistant gloves, goggles, protective clothing
Environmental Precautions: Prevent entry into sewers and waterways
Containment: Use absorbent materials (vermiculite, sand). Stop leak and prevent spread
Clean-up: Collect into containers for disposal. Ventilate and wash area with soap and water. Dispose of waste as required by regulations.
Handling: Use in well-ventilated areas. Avoid breathing mist or vapor. Avoid contact with skin and eyes
Storage: Store tightly closed in cool, dry, well-ventilated space. Keep away from incompatible substances such as strong acids and oxidizers. Maintain original labeling. Keep away from moisture; hygroscopic materials may degrade or clump if water enters container.
Special Considerations: Regularly check containers for leaks or damage. Store secondary containment to lessen environmental risk.
Control Parameters: No established ACGIH or OSHA exposure limits for this compound; treat as nuisance dust/vapor
Engineering Controls: Fume hoods, local exhaust ventilation recommended
Personal Protective Equipment: Gloves (nitrile or neoprene), splash goggles, impervious lab coat or apron
Respiratory Protection: Use NIOSH-approved respirator if airborne concentrations rise or risk of inhalation is significant
Hygiene Measures: Wash hands before breaks and after working with material. Remove contaminated clothing before leaving the workplace.
