Other Components: None intended or hazardous.
General: Move exposed person to fresh air, remove contaminated clothing.
Skin Contact: Wash exposed area with soap and water for at least fifteen minutes, seek medical advice if irritation develops.
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, continue rinsing, seek medical attention if symptoms persist.
Inhalation: Move to fresh air, monitor for respiratory distress, seek medical help if symptoms continue.
Ingestion: Rinse mouth with water, do not induce vomiting, seek medical attention if feeling unwell.
Advice for Medical Personnel: Provide symptomatic treatment and supportive care as indicated by the patient’s condition.
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam.
Unsuitable Extinguishing Media: High-pressure water jets can spread the material.
Specific Hazards: Burns with generation of carbon oxides and irritating fumes; dense smoke may occur.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus, chemical-resistant clothing.
Firefighting Procedures: Evacuate personnel from the area, cool containers with water spray to avoid rupture, control runoff to prevent environmental contamination.
Thermal Decomposition Products: Carbon monoxide, carbon dioxide, possibly small amounts of hazardous organic compounds.
Personal Precautions: Wear gloves, goggles, and lab coat; avoid inhaling vapors, ensure adequate ventilation.
Spill Cleanup Procedures: Absorb spill with inert material (sand, vermiculite), transfer to a proper waste container, avoid contact with skin and eyes.
Environmental Precautions: Prevent entry into drains, surface water, or soil; notify relevant authorities if large spills threaten the environment.
Methods for Containment: Stop the source of the spill, contain liquid, use nonsparking tools for handling.
Decontamination: Wash spill site after material pickup is complete.
Handling: Use only in well-ventilated areas, avoid contact with eyes, skin; wear proper protective equipment.
Storage Conditions: Keep tightly closed in a cool, dry, and well-ventilated place, protected from light and moisture.
Incompatibilities: Strong oxidizers, acids, and bases.
Hygiene Practices: Wash hands and face before eating, drinking, and after work.
Safe Transfer: Use grounded and bonded containers for large scale transfers, avoid inhaling fumes.
Occupational Exposure Limits: No established limits for this compound; follow good industrial hygiene practices.
Engineering Controls: Use fume hood or local exhaust.
Personal Protection: Chemical-resistant gloves (nitrile or neoprene), safety glasses with side shields, lab coat or apron.
Respiratory Protection: Use NIOSH/MSHA-approved respirator if vapor or mist exposure likely.

Hazardous Decomposition: Carbon oxides, possibly small quantities of toxic volatile compounds.
Polymerization: No risk expected under normal conditions.
Likely Routes of Exposure: Inhalation, dermal, ocular contact, oral.
Acute Toxicity: No acute toxicity data available; based on structure, large doses may cause mild gastrointestinal distress.
Skin Corrosion/Irritation: Mild skin irritation possible after prolonged contact.
Serious Eye Damage/Irritation: May cause redness, watering, temporary discomfort.
Respiratory Irritation: Vapors or fine mists could cause temporary coughing or sore throat.
Chronic Effects: No data indicating long-term effects; chronic exposure not recommended.
Carcinogenicity: No components listed as carcinogenic.
Reproductive Toxicity: No available data.
Symptoms Noted: Red eyes, skin redness, mild respiratory irritation.
Ecotoxicity: Not expected to be acutely toxic, but large quantities could harm aquatic organisms due to oil films on water surfaces.
Persistence and Degradability: Biodegradable over time in the environment.
Bioaccumulation Potential: Low likelihood due to fatty acid structure.
Mobility in Soil: Low mobility, likely to remain near point of release in soils.
Other Adverse Effects: May cause temporary film on surface waters, reducing oxygen exchange.
