Eye Contact: Flush eyes with clean running water for at least 15 minutes, remove contact lenses if present and safe, seek medical attention for irritation
Skin Contact: Remove contaminated clothing quickly, wash affected skin thoroughly with soap and water, discard soiled apparel
Inhalation: Move person to fresh air immediately, loosen tight clothing, provide oxygen if breathing difficulty develops, summon emergency support
Ingestion: Do not induce vomiting, rinse mouth, drink water only if conscious, seek immediate medical care due to potential kidney/liver damage
Note for Responders: Avoid direct exposure; use gloves, provide information to medical personnel regarding substance involved
Suitable Extinguishers: Carbon dioxide, dry chemical, foam, alcohol-resistant foam for large volume
Special Hazards: Emits toxic fumes of carbon monoxide and carbon dioxide when burning, explosive vapors possible in confined spaces
Protective Equipment: Full firefighter turnout gear, self-contained breathing apparatus
Precautions: Evacuate surrounding area, cool exposed containers, avoid run-off entering sewers or watercourses
Combustion Products: Expect release of irritating gases, dense black smoke if incomplete combustion
Spill Response: Stop source if safe, ventilate area thoroughly, prevent spread to water bodies, cover with inert absorbent (sand, earth)
Cleanup Method: Mop up with non-sparking tools, collect in containers for disposal, wash contaminated zone with soap and water after pick-up
Protection for Workers: Wear gloves, chemical goggles, approved respirator, boots, avoid skin/eye contact
Environmental Precautions: Block discharge into drains/soil, notify local authorities if spill could reach outside environment
Decontamination: Wash tools and PPE separately from normal laundry
Handling: Use local exhaust ventilation, avoid inhaling vapors, no eating or drinking in work area, wash hands after handling
Storage: Keep in tightly closed steel or HDPE drum, cool dry ventilated space, store away from oxidizers and acids
Incompatibles: Acids, bases, strong oxidizing agents, fire sources, strong reducing agents
Special Practices: Ground containers to prevent static discharge, mark storage zones clearly, keep away from direct sun and heat
Container Handling: Do not reuse empty drums for other chemicals without thorough reconditioning
Control Measures: Use explosion-proof ventilators, process enclosures, monitor air for vapor concentrations
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), goggles, lab coat, synthetic apron, closed shoes
Respiratory Protection: Half-mask or full respirator with organic vapor cartridges when limit could exceed safe value
Workplace Monitoring: Regular air sampling for 2-methoxyethanol, check for leaks at connections and pumps
Occupational Limits: ACGIH TLV: 0.1 ppm (skin), OSHA PEL: 25 ppm (TWA), low because of reproductive/fetal toxicity evidence
