General Advice: Seek immediate medical attention in all cases of suspected exposure. Remove contaminated clothing and shoes, rinse affected area with plenty of water. Move exposed person to fresh air immediately and prevent further exposure.
Inhalation: Remove to fresh air, keep the person at rest, administer oxygen if breathing is difficult, seek medical advice without delay.
Skin Contact: Wash exposed skin thoroughly with soap and water for at least 15 minutes, remove contaminated clothing, consult a doctor if irritation or pain persists.
Eye Contact: Rinse eyes cautiously with plenty of water for at least 15 minutes, keeping eyelids open, remove contact lenses if present and easy to do, seek medical attention.
Ingestion: Do not induce vomiting, rinse mouth with water, never give anything by mouth to an unconscious person, get medical care immediately.
Suitable Extinguishing Media: Use alcohol-resistant foam, dry chemical powder, or carbon dioxide. Water spray may be used to cool containers.
Unsuitable Extinguishing Media: Avoid direct water jet as it may spread the fire.
Specific Hazards: Combustion produces toxic fumes including nitrogen oxides and carbon oxides. Vapors can travel to ignition sources and flash back.
Protective Equipment: Firefighters require full protective gear and self-contained breathing apparatus.
Further Information: Move containers from fire area if safe to do so, use water spray to keep fire-exposed containers cool to prevent rupture. Evacuate area and fight fire from a safe distance.
Personal Precautions: Remove all sources of ignition, ventilate the area, use explosion-proof electrical equipment. Wear chemical-resistant gloves, goggles, and protective clothing.
Environmental Precautions: Prevent runoff to soil, drains, waterways, and sewers. Alert authorities if spillage has entered the environment.
Methods for Cleaning Up: Contain and collect spillage with non-combustible absorbent material like sand or earth, then place in chemical waste containers for disposal. Wash area with soap and water. Dispose in accordance with local regulations.
Spill Control Measures: Use spark-proof tools and a grounded system for transfer and clean-up.
Decontamination: Clean contaminated equipment thoroughly before reuse.
Precautions for Safe Handling: Handle inside a chemical fume hood or well-ventilated area. Wear appropriate personal protective equipment including gloves and eye protection. Avoid inhalation, ingestion, and skin contact. Ground and bond containers during transfer, avoid aerosol formation.
Safe Storage Conditions: Store tightly sealed in a cool, dry, and well-ventilated area away from sunlight, heat, and incompatible materials such as oxidizing agents and bases. Store in approved flammable liquid containers only.
Storage Incompatibilities: Keep away from acids, bases, strong oxidizers, reducing agents, and ignition sources.
Specific Storage Requirements: Maintain storage temperature below ambient whenever possible, use corrosion-resistant shelving.
Additional Protections: Ensure safety showers and eyewash stations are readily accessible.
Occupational Exposure Limits: Ethanol OSHA PEL: 1000 ppm (TWA), Ethyl Nitrate ACGIH TLV: Not established; use lowest feasible exposure levels
Engineering Controls: Use chemical fume hood, explosion-proof exhaust ventilation, and local capture at points of vapor emission.
Personal Protective Equipment:
