Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses, seek medical attention
Ingestion: Rinse mouth, do not induce vomiting, seek medical help immediately
Most Important Symptoms: Redness or irritation of skin and eyes, nausea, headache, drowsiness, symptoms may be delayed
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray
Unsuitable Media: Direct water stream may spread fire
Special Hazards: Emits toxic fumes (nitrogen oxides, carbon monoxide) on burning
Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective gear
Firefighting Advice: Use water spray to cool containers, keep out of drains, contain and collect firefighting water
Personal Precautions: Put on appropriate protective gear (gloves, goggles, lab coat), keep people away from spill zone
Environmental Precautions: Prevent contamination of soil, water, drains
Spill Response: Absorb with inert material (sand, earth), collect in chemical waste container, ventilate area, wash area with water after removal
Disposal: Dispose of in compliance with local regulations for hazardous substances
Safe Handling: Handle in a fume hood if possible, avoid dust formation, use only with adequate ventilation, avoid skin and eye contact, avoid breathing dust or vapors
Storage Conditions: Store in tightly closed container, cool, dry, well-ventilated location, keep separate from incompatible substances such as acids and oxidizers
Storage Temperature: Room temperature is usually sufficient, protect from sunlight and heat sources
Incompatibilities: Strong oxidizers, acids, alkalis, reducing agents
Exposure Limits: No established occupational exposure limit; minimize exposure through engineering controls
Engineering Controls: Use chemical fume hood or local exhaust
Eyes: Chemical splash goggles or face shield
Skin: Protective gloves (nitrile, neoprene), lab coat or protective apron
Respiratory Protection: Approved respirator if exposure risk exists, especially for dust or vapor
Hygiene Measures: Wash hands before eating, do not eat or drink in work area, remove contaminated clothing before leaving work area

Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Acute Toxicity: May cause nausea, headache, dizziness, and irritation to skin or eyes
Chronic Effects: Repeated exposure may lead to organ system toxicity, especially liver and kidneys
Irritation/Corrosivity: Skin and eye irritant, potential for respiratory tract irritation
Sensitization: No confirmed reports of allergic reaction, but care advised
Carcinogenicity: Not listed by NTP, IARC, OSHA
Other Effects: No comprehensive mutagenicity or reproductive toxicity data available; caution recommended
Ecotoxicity: Toxic to aquatic organisms and may cause long-term adverse effects in aquatic environments
Persistence and Degradability: Expected to be persistent in the environment due to low biodegradability
Bioaccumulation Potential: Moderate potential for bioaccumulation based on partition coefficient
Mobility in Soil: Low mobility due to low water solubility, tendency to remain in sediments or soil
Other Adverse Effects: No reports on ozone depletion or global warming potential, but safe disposal and spill prevention matter for environmental safety
Disposal Method: Dispose as hazardous chemical waste through licensed provider
Contaminated Packaging: Decontaminate if possible or dispose as hazardous waste
Special Steps: Do not dump into drains or natural water systems, follow local and federal chemical waste regulations at all times
