Ingestion: Rinse mouth with water, do not induce vomiting, consult a medical professional immediately
Special Notes: Rescuers should use personal protective equipment, symptoms might appear delayed
Suitable Extinguishing Media: Use foam, dry chemical, carbon dioxide, or water spray for small fires
Unsuitable Media: Water jets can spread burning liquid
Specific Hazards: Can produce toxic vapors of carbon monoxide, carbon dioxide
Firefighter Protection: Use self-contained breathing apparatus, full protective gear
Explosion Limits: Lower: 1.1% / Upper: Not well documented
Thermal Decomposition: Releases hazardous fumes under fire conditions
Personal Precautions: Wear chemical-resistant gloves, goggles, protective clothing, and suitable respirator
Environmental Precautions: Prevent spillage from entering drains, surface water, or soil
Spill Cleanup Methods: Absorb spillage with inert materials like sand or earth, collect for disposal in sealed containers, ventilate area, wash spill site after cleanup
Handling: Avoid inhalation and contact with skin or eyes, do not eat, drink, or smoke during use, use only in well-ventilated areas, grounded equipment and bonded containers help control static discharge
Storage: Store in tightly sealed, labeled containers out of direct sunlight, away from sources of ignition, incompatible substances, and oxidizers, refrigeration prolongs shelf-life, keep at stable temperature preferably between 2°C and 8°C
Exposure Limits: No specific OSHA or ACGIH exposure limit found; consult local guidelines
Engineering Controls: Local exhaust ventilation, process enclosure, or other engineering controls to keep airborne levels low
Personal Protection: Splash-proof goggles, lab coat, chemical-resistant gloves (nitrile or neoprene), respiratory protection if levels exceed guidelines, eyewash stations and emergency showers in work area

Respiratory or Skin Sensitization: No known sensitizing effect
Mutagenicity: Not classified as mutagenic
Reproductive Toxicity: Not classified as toxic to reproduction
Ecotoxicity: Data limited; may be toxic to aquatic organisms (fish, algae, daphnia) by analogy with similar aldehydes
Persistence and Degradability: Expected to undergo biodegradation in the environment but can persist if released in large quantities
Bioaccumulative Potential: Moderate; log Kow indicates potential for accumulation in organisms
Mobility in Soil: Likely low to moderate; volatile nature leads to some evaporation
Other Adverse Effects: Avoid release to the ecosystem, especially watercourses
Waste Disposal Methods: Collect and dispose of in accordance with local, regional, or national regulations; incineration or chemical treatment preferred for organic solvents
Container Disposal: Triple rinse then submit for chemical recycling or controlled landfill depending on jurisdiction
Precautions: Never discharge into sewers or waterways, use licensed hazardous waste contractor
