Inhalation: Move person to fresh air immediately, offer artificial respiration if breathing has stopped, keep airways clear
Eye Contact: Rinse eyes with water for at least 15 minutes, separate eyelids with fingertips, remove contact lenses if present and easy
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, don’t reuse clothing until laundered
Ingestion: Do not induce vomiting, rinse mouth with plenty of water, seek medical help quickly, show medical staff the container label
Most Important Symptoms: Irritation to skin, eyes, respiratory tract, delayed symptoms might involve nausea, damage to central nervous system
Suitable Extinguishing Media: Use water spray, dry chemical, foam or carbon dioxide, avoid direct water jet
Specific Hazards: Fire produces toxic fumes like carbon monoxide and carbon dioxide, vapors form explosive mixtures with air, runoff may pollute waterways
Advice for Firefighters: Wear self-contained breathing apparatus and protective clothing, keep upwind, cool exposed containers with water spray, evacuate area as needed
Personal protection: Protective gloves, boots, fire-resistant clothing, goggles or face shield
Personal Precautions: Isolate area, ventilate, wear chemical goggles, solvent-resistant gloves, and protective clothing
Environmental Precautions: Prevent spillage into sewers or waterways, notify environmental authorities if contamination occurs
Methods for Clean-Up: Absorb spill with inert material like sand or vermiculite, place waste in sealed container for disposal, decontaminate area with water and detergent
Procedures: Avoid producing vapors, keep ignition sources away, coordinate with local emergency response if large amount spilled
Handling: Only pour or transfer in well-ventilated places, ground all equipment, keep away from heat, sparks, static, avoid splashing, don’t breathe vapors, wash hands thoroughly after use
Storage: Store in tightly closed containers in cool, dry place, away from strong oxidants and acids, clearly label containers, segregate from food, beverages and feed
Special Notes: Regularly inspect storage area for leaks, maintain proper ventilation, use explosion-proof electrical fixtures
Exposure Limits: OSHA, NIOSH, or ACGIH do not publish official limits, but workplace air levels should stay low
Engineering Controls: Use chemical fume hoods, exhaust fans, spark-proof tools
Personal Protective Equipment: Nitrile or neoprene gloves, full goggles, flame-retardant lab coats, boots, avoid contact lenses
Respiratory Protection: NIOSH-approved organic vapor mask for short or low exposure, full respirator for heavy use
Hygiene Measures: Wash hands and face after handling, shower after long exposure, keep contaminated clothing separate

Conditions to Avoid: Sparks, open flames, temperatures above flash point, static charge build-up
Incompatible Materials: Acids, alkali metals, strong oxidizers like peroxides or nitrates, will violently react
Hazardous Decomposition: Burns to form carbon monoxide, carbon dioxide, possibly formaldehyde
Polymerization: No known dangerous polymerization under standard laboratory or industrial handling
Routes of Exposure: Inhalation, skin or eye contact, ingestion
Acute Effects: Irritation, headache, dizziness, nausea, central nervous system depression

Carcinogenicity: Not classified as carcinogen by OSHA, IARC, NTP
Other Effects: May cause adverse effects to human embryo or fetus, avoid for pregnant workers
Toxicity: Hazardous to aquatic life in large amounts, can negatively impact algae, daphnia, and fish
Persistence and Degradability: Biodegradable in soil and water in moderate time, but persistent in cases of heavy contamination
Bioaccumulative Potential: Not highly bioaccumulative, but repeated exposure should be avoided
Mobility in Soil: Moves easily through soil into groundwater in liquid form, danger of spreading in contaminated run-off
Other Info: Avoid large-scale release to environment, hazardous in municipal wastewater unless professional treatment used
