Inhalation: Move affected person to fresh air, give oxygen if breathing is difficult, consult a physician in case of lingering symptoms
Ingestion: Rinse mouth with water, consult medical advice, do not induce vomiting unless on medical advice
General Advice: Seek professional medical advice for persistent health effects, show this safety data information to first responders.
Suitable Extinguishing Media: Use alcohol-resistant foam, dry chemical, carbon dioxide (CO2), or water spray for large fires
Unsuitable Extinguishing Media: Direct stream of water may spread burning liquid
Special Hazards: Carbon oxides and irritating fumes may form during a fire
Firefighting Equipment: Wear self-contained breathing apparatus, full protective gear
Fire Precautions: Keep sources of ignition away, cool containers with water spray, remove containers from path of fire if safe to do so
Explosion Data: Heat may cause pressure to increase inside containers, risk of rupture.
Personal Precautions: Ventilate area, wear chemical-resistant gloves, goggles, and protective clothing to prevent direct contact
Environmental Precautions: Prevent product from entering drains, sewers, or waterways; contain and collect spillage
Methods for Clean-Up: Absorb spills with inert material like sand or earth, place in labeled, sealed containers for proper disposal
Decontamination Procedures: Wash spill area with water and detergent, ventilate for short period post-cleanup; dispose of contaminated cleanup materials following regulations.
Handling Advice: Work in a well-ventilated area, avoid inhaling vapors or mist, avoid skin and eye contact, don’t eat or drink when handling
Storage Requirements: Store in tightly sealed original containers in a cool, well-ventilated location, away from direct sunlight and sources of ignition
Incompatibilities: Avoid contact with strong oxidizers, strong acids, or strong bases which could trigger decomposition
Packaging: Use containers made of compatible materials such as glass or certain plastics, ensure clear labeling
Storage Temperature: Maintain temperature below 30°C; avoid freezing or excessive heat.
Occupational Exposure Limits: No specific limits established; follow general safe workplace exposure practices
Engineering Controls: Ensure local exhaust ventilation or use fume hood for large-scale handling
Respiratory Protection: Use an approved particulate or organic vapor respirator if vapors form or airborne concentrations exceed comfort levels
Hand Protection: Wear suitable chemical-resistant gloves such as nitrile or butyl rubber
Eye Protection: Close-fitting safety goggles or face shield required
Skin Protection: Protective lab coat or chemical-resistant clothing
Hygiene Measures: Wash hands before breaks and after work, remove contaminated apparel, ensure routine cleaning of work surfaces.

Thermal Decomposition: May decompose with release of irritating fumes if heated strongly
Conditions to Avoid: Heat, flame, sparks, direct sunlight
Materials to Avoid: Strong oxidizing agents, strong acids, alkali metals
Hazardous Reactions: None expected under normal handling; improper mixing with reactive substances may yield acetic acid and related irritants
Decomposition Products: Carbon monoxide, carbon dioxide, acetic acid, possible low-molecular aldehydes.
Acute Toxicity: Not acutely toxic by ingestion, inhalation, or skin contact based on available laboratory data
Skin Corrosion/Irritation: Mild to moderate irritation may occur upon prolonged contact
Eye Damage/Irritation: May produce mild discomfort or redness
Respiratory Effects: Exposure to vapor above comfort threshold may cause transient throat or lung irritation
Chronic Effects: No data suggesting chronic toxicity for this compound; similar esters have low long-term hazard in typical application scenarios
Sensitization: Not identified as a sensitizer from available tests
Mutagenicity/Carcinogenicity: Not expected; not listed by IARC, ACGIH, NTP, or OSHA.
Ecotoxicity: Possibly toxic to aquatic organisms if large-scale spillage occurs; predicted low eco-toxic effect at environmental concentrations
Persistence and Degradability: Structure suggests slow biodegradability, typical for long-chain acetate esters
Bioaccumulation Potential: Unlikely to bioaccumulate significantly due to moderate log Kow
Mobility in Soil: Limited mobility, will adsorb to soil particulate
Other Adverse Effects: No ozone depletion potential, not classified as hazardous waste under global protocols.
Waste Treatment Methods: Collect unused or leftover liquid as hazardous chemical waste, incinerate according to local guidelines
Contaminated Packaging: Triple rinse containers before suitable disposal or recycling, follow national recommendations
