Hazard Identification

Hazard Class: Classified as hazardous based on eye and skin irritation potential
GHS Symbols: Exclamation Mark
Risk Statements: Irritating to eyes and skin, potentially harmful if inhaled or swallowed, not expected to present fire hazard under normal conditions
Precautionary Statements: Avoid skin contact, use proper ventilation, wear protective gloves and eyewear, avoid breathing vapors

Composition / Information on Ingredients

Main Component: Ethylene Glycol Monophenyl Ether (approx. 99%)
Potential Impurities: Trace glycol derivatives may occur during manufacture
Stabilizers or Additives: None typically present in technical grade forms

First Aid Measures

Eye Contact: Flush immediately with plenty of water, continue for several minutes, seek medical attention if irritation persists
Skin Contact: Wash thoroughly with soap and water, contaminated clothing should be removed and washed before reuse
Inhalation: Move affected person to fresh air, keep at rest and warm, seek help if symptoms appear
Ingestion: Rinse mouth with water, do not induce vomiting, seek immediate medical advice, show product label to medical staff

Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide
Hazardous Decomposition Products: May emit carbon monoxide, carbon dioxide under fire conditions
Unusual Fire Hazards: Containers may burst in heat, runoff may be hazardous to the aquatic environment
Firefighter Precautions: Wear full protective gear, including self-contained breathing apparatus

Accidental Release Measures

Personal Precautions: Wear gloves, goggles, and suitable clothing, ensure adequate ventilation
Spill Clean-Up: Soak up with inert absorbent material such as sand or earth, collect in properly labeled containers
Environmental Precautions: Prevent entry into sewers, groundwater, and surface water, notify authorities if large quantities spilled

Handling and Storage

Handling Practices: Use only in well-ventilated areas, avoid inhaling vapors, wear personal protective equipment, don't eat or drink when using chemicals
Storage Conditions: Keep containers tightly closed, store in cool, dry, well-ventilated place, away from sources of ignition, incompatible materials such as oxidizers

Exposure Controls and Personal Protection

Ventilation: Ensure adequate local exhaust in areas of regular use
Personal Protection: Gloves resistant to organic solvents, safety goggles to protect eyes, protective clothing to avoid skin contact
Respiratory Protection: Use appropriate respirators if airborne concentrations exceed recommended limits
Exposure Limits: Occupational exposure limits differ by country; some workplaces may not have specific limits set for this chemical, making line management and regular air quality monitoring important
