Inhalation: Move any exposed person into fresh air. Seek immediate medical attention if symptoms such as coughing, breathing difficulty, or dizziness occur.
Skin Contact: Remove contaminated clothing. Wash affected areas with copious amounts of soap and water for at least 15 minutes. Immediate medical advice if irritation persists.
Eye Contact: Flush opened eyes with running water for at least 15–20 minutes. Get prompt medical consultation if discomfort or redness continues.
Ingestion: Rinse mouth thoroughly with water. Seek medical help without delay. Do not induce vomiting unless instructed by medical personnel.
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, or alcohol-resistant foam.
Unsuitable Media: Do not use water jet, as product may react and produce hazardous fumes.
Special Hazards: On combustion, releases toxic and irritating gases such as hydrogen fluoride, boron oxides, and nitrogen oxides.
Protective Equipment: Use self-contained breathing apparatus (SCBA) and complete body protection. Firefighters require chemical-resistant clothing.
Advice for Firefighters: Cool containers with plenty of water spray to prevent bursting under high heat.
Personal Protective Equipment: Protective gloves, chemical safety goggles, impervious clothing. Respiratory protection in poorly ventilated areas.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Avoid discharge into drains, waterways, or soil.
Containment and Cleaning: Absorb on inert material (sand, earth, vermiculite). Collect in appropriate container for disposal. Dispose of in accordance with local regulations.
Decontamination: Wash affected area with detergent and water. Ventilate closed spaces before entry.
Handling: Use only in a chemical fume hood or well-ventilated area. Avoid contact with skin, eyes, and clothing. Do not breathe mist or vapor. Wash hands thoroughly after handling.
Storage: Keep container tightly closed in a cool, dry, and well-ventilated place. Store away from moisture, acids, and incompatible substances. Use corrosion-resistant containers. Do not store near heat sources or direct sunlight.
Incompatible Materials: Strong oxidizers, strong acids, moisture-sensitive compounds.
Engineering Controls: Local and general ventilation to keep airborne concentrations below exposure limits. Use fume hood for large-scale operations.
Personal Protective Equipment: Chemical-resistant gloves (nitrile recommended), safety goggles or face shield, lab coat or chemical suit. Employ respiratory protection when ventilation is insufficient.
Exposure Limits: No established occupational exposure limits for this compound; apply standard practices for handling chemicals of uncertain toxicity.
Hygiene Measures: Change contaminated clothing. Do not eat, drink, or smoke during use. Wash hands and face after work.

Conditions to Avoid: Heat, open flame, moisture, direct sunlight, contact with incompatible chemicals.
Hazardous Decomposition Products: Hydrogen fluoride, boron oxides, nitrogen oxides, other fluorinated organic fragments.
Incompatible Materials: Moisture, strong acids, oxidizing agents.
Routes of Exposure: Inhalation, ingestion, skin, and eye contact.
Acute Toxicity: Limited toxicity data for humans. In animals, moderate toxicity following ingestion or skin exposure. Inhalation of vapor or aerosol can cause irritation to mucous membranes and upper respiratory tract.
Chronic Effects: Extended or repeated exposure may lead to skin sensitization, persistent dermatitis, or eye damage.
Symptoms: Irritation of eyes, skin, throat, breathing difficulties, cough, headache, gastrointestinal discomfort.
Carcinogenicity/Mutagenicity: No data suggesting carcinogenic or mutagenic potential. Handle as a potentially hazardous material.
Aquatic Toxicity: Moderately toxic to aquatic organisms; avoid release to the environment.
Persistence and Degradability: Not readily biodegradable in water or soil; may persist for weeks.
Bioaccumulative Potential: Low to moderate potential for bioaccumulation in aquatic species.
Mobility in Soil: Most of the compound permeates water easily, may reach groundwater.
Other Adverse Effects: Fluorinated components may pose long-term environmental risks.
Waste Treatment Methods: Dispose of via an approved chemical waste facility. Rinse containers and contaminated materials fully before discarding. Do not pour into sewer, drains, or any natural water bodies.
