Eye Contact: Rinse eyes with water for at least 15 minutes, remove contact lenses, seek medical attention if irritation persists
Skin Contact: Wash affected area with soap and water, remove contaminated clothing, get medical help if irritation develops
Inhalation: Move affected person to fresh air, support breathing if needed, consult a physician if symptoms continue
Ingestion: Rinse mouth, give water to drink if conscious, never induce vomiting, seek medical advice immediately
Note for Physicians: Treat symptomatically, monitor respiratory and cardiovascular function
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide
Specific Hazards: Vapors heavier than air, may form explosive mixtures with air at higher temperatures, combustion produces carbon monoxide and dioxide
Protective Equipment for Firefighters: Wear self-contained breathing apparatus, chemical resistant clothing
Special Procedures: Cool containers exposed to fire with water spray, control runoff to prevent entry into sewers or waterways
Explosion Data: Vapors may ignite rapidly if exposed to sparks or flames
Personal Precautions: Evacuate area, ventilate, avoid contact with skin, eyes, and clothing, use gloves and goggles
Environmental Precautions: Prevent runoff into drains, watercourses, and soil by diking
Methods for Clean-Up: Contain and collect spill with inert absorbent materials like sand, place in chemical waste container
Reference to Other Sections: Refer to exposure controls, personal protection, and disposal information for handling contaminated material
Safe Handling: Avoid inhaling vapors, use only in well-ventilated areas, prevent contact with skin and eyes, wash hands after use
Storage Requirements: Store in tightly closed containers, keep in a cool, dry, well-ventilated location away from sources of ignition and incompatible materials
Incompatible Materials: Strong acids, strong oxidizing agents, reactive metals
Other Precautions: Provide eye wash stations and safety showers near usage areas, label containers clearly, minimize splashing and vapor release by keeping containers closed
Occupational Exposure Limits: No established ACGIH TLV or OSHA PEL for dipropylene glycol butyl ether
Engineering Controls: Use local exhaust ventilation, maintain eyewash stations, consider explosion-proof equipment in areas with vapor formation
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile or neoprene), splash-proof safety goggles, long-sleeved protective clothing
Respiratory Protection: Use approved respirator if vapor or mist concentrations exceed recommended guidelines
Hygiene Measures: Remove contaminated clothing immediately, wash thoroughly after handling, do not eat or smoke while using this product

Hazardous Decomposition Products: Produces carbon monoxide, carbon dioxide, and other irritating fumes upon combustion or decomposition
Conditions to Avoid: Keep away from open flames, hot surfaces, sparks, static discharge
Routes of Exposure: Inhalation, skin contact, ingestion, eye contact
Acute Toxicity: Oral LD50 (rat) > 2000 mg/kg, Dermal LD50 (rabbit) > 2000 mg/kg
Skin Corrosion/Irritation: May cause mild irritation following prolonged or repeated contact
Serious Eye Damage/Irritation: Causes eye irritation, redness, tearing can occur
Respiratory Effects: Inhalation of vapor can produce dizziness, headache, and drowsiness at high concentrations
Chronic Effects: No significant data to support chronic toxicity, repeated or prolonged contact increases risk of dermatitis
Mutagenicity/Carcinogenicity/Reproductive Toxicity: No data show mutagenic, carcinogenic, or reproductive effects in standard animal testing
Ecotoxicity: Slightly toxic to aquatic life, EC50 (Daphnia magna) estimated at >1000 mg/L, LC50 (Fish, 96-hr) >1000 mg/L
Persistence and Degradability: Expected to be readily biodegradable, will not persist in soil or water
Bioaccumulative Potential: Low based on log Kow value
