General: Take affected individual to fresh air and keep warm and at rest
Inhalation: Remove person to fresh air, keep comfortable, seek medical help if symptoms like dizziness, headache, or nausea persist
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, do not reuse clothes until properly cleaned
Eye Contact: Rinse eyes gently with plenty of water for at least 15 minutes, remove contact lenses after a few minutes if present, seek medical attention if irritation continues
Ingestion: Rinse mouth with water, do not induce vomiting, seek medical advice, never give anything by mouth to an unconscious person
Suitability of extinguishing media: Use water spray, foam, dry powder, or carbon dioxide
Hazards during fire: Vapors can form explosive mixtures with air, decomposition by products include carbon monoxide, carbon dioxide, and sometimes hazardous organic compounds
Firefighter Protection: Wear self-contained breathing apparatus and full protective gear
Advice for firefighters: Approach fire from upwind, prevent runoff from entering drains, cool drums with water spray even after fire appears extinguished to stop re-ignition
Personal Precautions: Evacuate unnecessary personnel, ensure adequate ventilation, wear suitable protective equipment including chemical goggles and gloves
Environmental Precautions: Prevent from entering drains, waterways, or soil
Containment Methods: Stop leaks if possible without risk, absorb with inert material like sand or earth, collect into suitable containers for disposal
Spill Clean-Up: Use non-sparking tools, ventilate area, wash spill area with water after pick up, avoid breathing vapors
Safe Handling Practices: Work in a well-ventilated area, avoid breathing vapors, avoid contact with eyes, skin, and clothing
Precautions for Safe Storage: Store in tightly closed containers in a cool, dry, well-ventilated place, away from incompatible substances
Incompatible Materials: Strong acids, bases, oxidizers
Storage Conditions: Store away from direct sunlight, sources of ignition, and heat sources, use proper grounding to avoid static discharge
Occupational Exposure Limits: No established OSHA PEL or ACGIH TLV for DPG butyl ether; use guidelines for similar glycol ethers if available
Engineering Controls: Use local exhaust ventilation or mechanical ventilation to maintain airborne concentrations below recommended limits
Respiratory Protection: Wear suitable respiratory protection when ventilation is insufficient
Skin Protection: Wear impermeable gloves, long sleeves, chemical-resistant clothing
Eye Protection: Wear chemical safety goggles or face shield
Hygiene Measures: Wash hands before breaks and after work, do not eat or drink in work area
Appearance: Clear, colorless liquid
Odor: Mild ether-like
pH: Not applicable (neat material)
Boiling Point Range: 230°C - 256°C (446°F - 492°F), depending on isomer composition
Melting Point: -80°C or lower
Flash Point: Approximately 107°C (225°F) closed cup
Evaporation Rate: Slower than butyl acetate
Vapor Pressure: Less than 0.1 mm Hg at 20°C
Specific Gravity: About 0.95 at 20°C
Solubility in Water: Miscible
Partition Coefficient (n-octanol/water): Log Kow expected between 0.5 and 1.0
Viscosity: Moderately high, similar to other glycol ethers
Chemical Stability: Stable in normal conditions
Possibility of Hazardous Reactions: No dangerous reactions expected under recommended use
Conditions to Avoid: Prolonged heating, open flames, high-energy ignition sources
Incompatible Materials: Strong acids, alkalis, oxidizers
Hazardous Decomposition Products: In a fire, produces carbon dioxide, carbon monoxide, and low levels of other hazardous gases
Acute Toxicity: Low oral toxicity, calculated LD50 (rat, oral) greater than 3000 mg/kg
skin corrosion/irritation: Mild to moderate transient skin irritation with prolonged contact
Serious Eye Damage/Irritation: Can cause moderate eye irritation
Respiratory or Skin Sensitization: Not expected to cause sensitization in normal use
Chronic Effects: No evidence of chronic systemic toxicity in repeated dose studies on similar glycol ethers
Other Information: Central nervous system depression possible at high vapor concentrations, headache and dizziness commonly reported in overexposure
Aquatic Toxicity: Low acute toxicity for aquatic organisms, LC50 (fish) estimated over 100 mg/L
Persistence and Degradability: Expected to be readily biodegradable
Bioaccumulation Potential: Low, Log Kow near zero suggests little risk
Mobility in Soil: High mobility in soil and water due to high solubility
Other Adverse Effects: Spills may cause temporary oxygen demand in surface water, avoid direct discharges to the environment
