Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, occasionally lifting upper and lower eyelids. Remove contact lenses if present and easy to do. Seek medical attention if redness or irritation persists.
Skin Contact: Remove contaminated clothing. Wash affected areas with soap and water for at least 15 minutes. If irritation develops, consult a physician.
Inhalation: Move individual to fresh air. Provide oxygen or artificial respiration if breathing becomes difficult. Seek medical assistance for any persistent symptoms.
Ingestion: Rinse mouth with water. Do not induce vomiting unless directed by medical personnel. Call poison control center or seek medical attention for significant ingestion or symptoms.
Most Important Symptoms/Effects: Burning, stinging, coughing, difficulty breathing, nausea.
Suitable Extinguishing Media: Dry chemical, CO2, foam, or water spray. Use methods compatible with surrounding materials.
Unsuitable Extinguishing Media: High-pressure water jets that may spread fire.
Specific Hazards Arising from Chemical: May emit toxic gases including hydrogen fluoride, nitrogen oxides, sulfonyl oxides, and carbon oxides upon decomposition.
Firefighter Protection: Wear self-contained breathing apparatus and full protective gear. Take precautions against exposure to combustion products.
Special Procedures: Isolate the area, remove unaffected containers from fire zone, ventilate space post-extinguishing.
Personal Precautions: Wear chemical-resistant gloves, safety goggles, and protective clothing to limit exposure.
Environmental Precautions: Prevent product from entering drains, sewers, or waterways. Contain spills using inert material such as sand or clay.
Cleanup Methods: Absorb material on vermiculite, sand, or other inert medium. Collect in suitable container for disposal according to local regulations. Ventilate spill area and wash thoroughly after cleanup.
Notification Procedures: Report significant releases to relevant local authorities as required.
Handling: Always operate in a chemical fume hood or well-ventilated area. Avoid inhalation of vapors/mists. Minimize skin and eye contact by wearing protective equipment.
Storage: Keep container tightly closed in a cool, dry, and well-ventilated place. Avoid proximity to moisture, strong oxidizers, acids, and bases. Clearly label containers. Store away from sources of ignition and incompatible substances.
Incompatible Materials: Reactive with strong oxidizers, reducing agents, and moisture-sensitive substances.
Storage Conditions: Recommended storage temperature below 30°C. Prevent prolonged exposure to air to avoid hydrolysis.
Control Parameters: No established occupational exposure limits for this substance. Minimize airborne concentrations.
Engineering Controls: Use chemical fume hood, local exhaust ventilation, and equipment designed to avoid splashing or accidental release.
Personal Protective Equipment: Protective safety goggles, gloves (nitrile recommended), long-sleeved lab coat or apron. Use appropriate respiratory protection if concentrations exceed comfort threshold.
Hygiene Measures: Avoid eating, drinking, or smoking in handling areas. Wash hands thoroughly after use and before meals.
