Skin Contact: Remove contaminated clothing, wash affected area with soap and water for at least 15 minutes; call for medical attention if irritation develops
Eye Contact: Rinse eyes under plenty of flowing water for 15 minutes or more, hold eyelids apart, seek immediate medical attention
Ingestion: Do not induce vomiting, rinse mouth with water if conscious, contact poison control or a doctor urgently
Main Symptoms/Effects: Nausea, headache, drowsiness, skin discoloration (cyanosis), respiratory distress
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide
Unsuitable Media: Water in a heavy stream may spread fire
Hazardous Combustion Products: Emits toxic fumes of nitrogen oxides, carbon monoxide, carbon dioxide, and possibly methylamines
Firefighting Instructions: Firefighters wear full protective gear and self-contained breathing apparatus; prevent runoff from entering drains; cool containers with water spray
Flash Point: Approx. 140°C (estimate needed for precision)
Explosion Data: Data limited; avoid friction, sparks, and open flames
Personal Precautions: Wear chemical-resistant gloves, goggles, lab coat, and NIOSH-approved respirator if dust or vapor is present; evacuate unnecessary personnel
Environmental Precautions: Avoid contaminating soil, surface water, and drains; contain spill with sand or inert material
Cleanup Methods: Absorb liquid with sand, earth, or inert absorbent; place in properly labeled, sealed containers for disposal; ventilate area
Decontamination: Wash spill site after material cleanup is complete; prevent further leakage or spillage
Handling: Avoid direct contact with skin, eyes, and clothing; use only with proper ventilation or fume hood; prevent dust or aerosol generation; handle with dedicated equipment
Storage: Store tightly closed in a cool, dry, well-ventilated area away from heat, direct sunlight, strong oxidizers, and foodstuffs; use secondary containment
Special Requirements: Segregate from incompatible substances; label all containers; store in original container, preferably with desiccant
Permissible Exposure Limits: No OSHA PEL established; minimize exposure through work practice controls
Engineering Controls: Use chemical fume hood, local exhaust ventilation, eye-wash station, and safety shower
Personal Protective Equipment (PPE): Butyl rubber or nitrile gloves, flame-resistant lab coat, safety goggles or face shield, suitable respirator for dust/fume/mist

Acute Toxicity: Oral LD50 (rat): approx. 400 mg/kg; may cause drowsiness, cyanosis, hemolysis, methemoglobinemia, kidney or liver damage
Chronic Effects: Prolonged or repeated exposure can damage the blood, kidneys, liver, and nervous system; may increase risk of cancer
Symptoms: Headache, dizziness, confusion, blue coloration of skin, shortness of breath; severe cases can cause convulsions or unconsciousness
Carcinogenicity: Not classifiable based on available data, but structurally related compounds are considered potential carcinogens
Mutagenicity: Evidence suggests potential for DNA damage in laboratory tests
Reproductive Toxicity: Not enough data available
Aquatic Toxicity: Toxic to aquatic organisms; causes lasting adverse effects in the aquatic environment
Persistence and Degradability: Not readily biodegradable; persists in the environment
Bioaccumulative Potential: May bioaccumulate in aquatic species; no reliable BCF value available
Mobility in Soil: Low solubility in water leads to moderate mobility in soil; may bind strongly to soils and sediments
Other Adverse Effects: Toxic effects can be magnified along the food chain, harmful in very small quantities to many aquatic organisms
