Ingestion: Do not induce vomiting, rinse mouth with water, never give anything by mouth if the person is unconscious, seek prompt medical help
Major Symptoms: Skin and eye redness, burning, severe irritation or pain, allergic reactions, headache, shortness of breath
Suitable Extinguishing Media: Alcohol-resistant foam, carbon dioxide, dry chemical powder, water fog (do not use water jet directly on substance)
Specific Hazards: Vapors may form explosive mixtures with air, containers may explode when hot, may emit toxic fumes of nitrogen oxides and silicon oxides
Protective Equipment for Firefighters: Wear full turnout gear, including self-contained breathing apparatus, chemical-resistant gloves and boots
Special Procedures: Cool containers with water spray to prevent pressure buildup, remain upwind, prevent runoff from entry into waterways
Advice: Recognize that fire will produce intense heat and dangerous gases; evacuation of the area and use of remote firefighting techniques may be required
Personal Precautions: Evacuate unnecessary personnel, wear respiratory protection, use chemical-resistant gloves, safety goggles, avoid contact with skin and eyes, ventilate area
Environmental Precautions: Prevent further leakage or spillage, avoid entry to drains, sewers, waterways, inform authorities if significant contamination occurs
Clean-Up Methods: Absorb with sand, earth, or inert absorbent, place into closed chemical waste containers, wash spill site after material pickup, ventilate contaminated area
Special Instructions: Use spark-proof tools, avoid generating aerosols, dispose of all cleanup materials in accordance with local and national regulations, decontaminate all personnel and equipment exposed to spilled material
Safe Handling: Work in a chemical fume hood or well-ventilated space, wear protective clothing, keep away from heat, sparks, open flames, do not breathe vapors, avoid contact with skin, eyes, clothing
Conditions for Safe Storage: Store in tightly closed, clearly labeled containers, keep container in a cool, dry, well-ventilated place, separate from acids, oxidizers, and incompatible chemicals
Storage Temperatures: Preferably below 25°C (77°F)
Incompatible Materials: Strong acids, bases, oxidizing agents, moisture
Advice on Storage Stability: Regularly check containers for signs of leaks, product may slowly hydrolyze releasing ethanol, handle opened containers with care to avoid air and moisture contamination
Exposure Limits: No occupational exposure limit assigned by OSHA or ACGIH, treat as hazardous based on toxic effects
Engineering Controls: Use chemical fume hood, explosion-proof ventilation, eyewash and safety shower stations nearby
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), splash goggles, face shield, lab coat or impervious apron, long sleeves and pants, closed-toe shoes
Respiratory Protection: Use a NIOSH-approved organic vapor respirator in case of insufficient ventilation or aerosol risk
