General Advice: Seek immediate medical assistance—bring this data sheet when seeking help
Inhalation: Remove to fresh air, keep patient still and respond to breathing difficulties; provide artificial respiration if breathing has stopped
Skin Contact: Remove contaminated clothing, vigorously flush skin with running water for 15 minutes; do not delay decontamination
Eye Contact: Immediately rinse eyes with lukewarm water for at least 20 minutes, manually separate eyelids if needed
Ingestion: Rinse mouth, do not induce vomiting for unconscious or convulsing individuals, seek immediate medical advice
Acute Symptoms: Nausea, vomiting, headache, sweating, yellow discoloration of skin, confusion, convulsions, muscle rigidity
Delayed Effects: Liver and kidney damage, metabolic acidosis, hyperthermia
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, water spray (avoid high-pressure water jets)
Unsuitable Extinguishing Media: High-pressure water streams
Specific Fire Hazards: Combustion releases toxic gases (nitrogen oxides, carbon monoxide, phenolic vapors); substance may intensify fire due to oxidizing nitro groups
Advice for Firefighters: Full protective gear and positive-pressure self-contained breathing apparatus required; cool containers exposed to flames with water
Special Procedures: Remove product containers from fire area if it can be done safely
Personal Precautions: Evacuate area, ventilate space, avoid contact with skin or eyes, use recommended personal protective equipment
Environmental Precautions: Prevent substance from entering drains, surface and ground water, soil, or vegetation; notify authorities in case of significant spill
Containment & Clean-up: Sweep up with non-sparking tools, collect in appropriately labeled chemical waste drums; absorb with sand or inert material; avoid dust generation; dispose as hazardous waste
Handling: Use only in well-ventilated areas, avoid breathing dust or fumes, avoid ingestion and skin/eye contact, wash thoroughly after use, use minimal quantities to avoid exposure
Storage: Store in tightly closed, clearly labeled containers in a cool, dry, ventilated area away from direct sunlight, oxidizers, acids, ignition sources, and foodstuffs; keep locked up and out of reach of children; maintain temperature below 30°C; segregate from incompatible material such as strong oxidizers and reducing agents
Occupational Exposure Limits: OSHA: 0.2 mg/m³ (TWA), ACGIH: 0.05 mg/m³ (TWA), NIOSH: 0.2 mg/m³ (TWA)
Engineering Controls: Local exhaust ventilation, safety shower and eyewash station nearby
Personal Protection: Chemical-resistant gloves (nitrile, neoprene), impervious protective clothing, safety goggles or face shield, fitted respirator (P3 filter for particulates, organic vapor cartridge for fumes)
