Molecular Weight: 114.23 g/mol
Component: 3-Ethylhexane
Concentration Range: 100%
Inhalation: Move person to fresh air. Seek medical attention if symptoms such as coughing, dizziness or shortness of breath develop.
Skin Contact: Remove contaminated clothing. Wash thoroughly with soap and water. If irritation persists, consult a healthcare professional.
Eye Contact: Rinse cautiously with water, removing contact lenses if present and easy to do. Continue rinsing for at least 15 minutes. Seek medical help if eye irritation occurs.
Ingestion: Rinse mouth. Do not induce vomiting unless instructed by medical personnel. Get medical advice if unwell or if large quantity swallowed.
Suitable Extinguishing Media: Use foam, dry chemical, or carbon dioxide; never use water jets directly on fire.
Specific Hazards Arising from Chemical: Vapors may form explosive mixtures with air. Fire may produce toxic gases such as carbon monoxide and carbon dioxide.
Special Firefighting Procedures: Use self-contained breathing apparatus and full protective gear. Cool containers exposed to fire with water spray.
Personal Precautions: Eliminate ignition sources. Ventilate area. Avoid inhalation and contact with skin or eyes.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains or waterways.
Methods for Containment and Cleanup: Absorb with inert material like dry sand or earth. Scoop up and place into labeled container for disposal following local regulations.
Handling: Avoid breathing vapors. Use in well-ventilated areas. Do not smoke, eat, or drink when using this chemical. Avoid contact with skin, eyes, and clothing. Keep away from sources of ignition.
Storage: Store in tightly closed original container in a cool, dry, well-ventilated area. Keep away from open flames and heat sources. Store away from incompatible substances such as strong oxidizers.
Control Parameters: No workplace exposure limits established specifically for 3-Ethylhexane. Use general hydrocarbon limits as a guideline.
Engineering Controls: Ensure good ventilation, especially in confined areas. Use explosion-proof equipment where risk of fire or explosion may be present.
Personal Protective Equipment: Wear chemical-resistant gloves, splash-proof safety goggles or face protection, lab coat, and, if risk of inhalation exists, an approved respirator.
Hygiene Measures: Do not eat, drink, or smoke during use. Wash hands and any exposed skin thoroughly after handling.
