Inhalation: Move affected person to fresh air, monitor for respiratory distress, medical attention required if symptoms do not subside
Skin Contact: Wash exposed area with soap and water for at least 15 minutes, remove contaminated clothing, seek medical evaluation if irritation persists
Eye Contact: Immediately flush eyes with plenty of water for at least 20 minutes, keep eyelids apart and move the eye in every direction, prompt medical attention suggested
Ingestion: Rinse mouth, do not induce vomiting, offer water to drink if conscious, consult a physician as soon as possible
Suitable Extinguishing Media: Alcohol-resistant foam, carbon dioxide, dry chemical powder, water spray
Specific Hazards from Fire: Vapors may form explosive mixtures with air, burns with a nearly invisible flame, generates toxic gases (carbon oxides, aldehydes) when decomposed in fire
Advice for Firefighters: Wear full protective gear and self-contained breathing apparatus, use water spray to cool tanks and containers, approach fire from upwind
Unusual Fire Hazards: Containers may rupture due to pressure build-up, run-off from firefighting can pollute waterways
Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid breathing vapors, wear gloves, safety goggles, suitable protective clothing
Environmental Precautions: Prevent runoff into sewers and waterways, contain spill with inert absorbent material (sand, earth)
Methods for Clean-Up: Absorb spillage with vermiculite, sand, or other inert material, place in suitable container for disposal, wash area with water after pick-up, secure container and label for disposal
Handling: Use only with proper local exhaust ventilation, avoid sources of ignition, keep container tightly closed when not in use, avoid contact with skin and eyes, ground containers when transferring liquid
Storage: Store away from direct sunlight, incompatible substances (strong oxidizers, acids), keep in cool, well-ventilated area, always store in properly labeled containers, keep away from food, beverages, and animal feed
Occupational Exposure Limits: OSHA/NIOSH not established for this compound; ACGIH TLV for similar glycols: 50 ppm TWA (for guidance)
Engineering Controls: Eyewash stations, safety showers, local exhaust ventilation
Personal Protective Equipment: Splash-proof safety goggles, chemical-resistant gloves (nitrile or butyl rubber), full-sleeved protective clothing, vapor respirators if exposure is likely, impermeable boots
General Hygiene: Wash hands before breaks, after working with substance, remove contaminated clothing immediately
