Inhalation: Remove person to fresh air immediately, keep at rest in a position comfortable for breathing, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, gently wash skin with plenty of water and cleanser for a minimum of 20 minutes, do not rub or scrub, medical evaluation recommended
Eye Contact: Immediately flush eyes with water for at least 15 minutes, use fingers to keep eyelids apart, remove contact lenses if present and continue rinsing, consult physician if irritation continues
Ingestion: Rinse mouth, do not induce vomiting, drink water if conscious, obtain medical attention
Most Important Symptoms and Effects: Skin rash, burning sensation, headaches, coughing, labored breathing, sensitization (potential reaction increase after repeated contact)
Suitable Extinguishing Media: Use dry chemical powder, foam, or carbon dioxide, water spray for larger fires
Hazards from Combustion: Toxic vapors of nitrogen oxides, carbon monoxide, carbon dioxide may develop under fire conditions, benzene and formaldehyde may be present in small amounts
Protective Equipment for Fire Fighters: Full protective clothing, self-contained breathing apparatus recommended
Special Procedures: Move containers from fire area if can be done without risk, avoid inhalation of fumes, keep adjacent containers cool by spraying with water
Personal Precautions: Evacuate all non-essential personnel, ventilate area, wear gloves, goggles, and suitable respirator
Emergency Procedures: Keep away from ignition sources or heat, avoid dust generation
Methods for Containment and Cleanup: Contain spilled material with inert absorbent (sand, earth), collect in container for disposal, wash contaminated surface with soap and water, dispose according to regulations
Environmental Precautions: Prevent entry into waterways, sewers, basements, or confined areas, notify local authorities in case of large spill
Precautions for Safe Handling: Wear personal protective equipment, avoid dust formation, provide local exhaust ventilation, wash hands thoroughly after handling, always keep container tightly closed when not in use
Safe Storage Conditions: Store at 2–8°C, in a well-ventilated, low-humidity place, avoid exposure to direct sunlight, segregate from incompatible substances such as oxidizers or acids
Incompatible Materials: Strong oxidizers, strong acids, bases, reducing agents
Exposure Limits: No established occupational exposure limits, minimize exposure as a best practice
Engineering Controls: Use process enclosures, fume hoods, local exhaust ventilation
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles or full-face shield, long-sleeved lab coat, avoid open skin contact
Respiratory Protection: Use NIOSH-approved respirator if handling in conditions where dust or vapor can be generated

Decomposition Products: Nitrogen oxides, carbon monoxide, carbon dioxide, toxic organic vapors, trace benzene derivatives
Conditions to Avoid: Heat, flame, prolonged exposure to light or humidity, open containers
Acute Toxicity: No precise LD50 data, low-acuity exposure risk with prompt decontamination, higher risk if inhaled in dust or vaporized
Skin Sensitization: Possible in susceptible individuals after repeated or extended contact
Eye Effects: Irritation, redness, possible chemical conjunctivitis
Health Risks: In sensitive populations, contact can increase likelihood of allergic reaction or develop skin rashes, respiratory hypersensitivity if airborne
Carcinogenicity: Not listed by IARC, NTP, or OSHA as a suspected or confirmed carcinogen
Mutagenic Effects: No mutagenicity data reviewed
Reproductive Toxicity: No conclusive studies, typical caution suggested with laboratory chemical reagents
Ecotoxicity: Toxic to aquatic organisms in concentrated form, risk of bioaccumulation in contaminated environments low due to rapid breakdown in soil and water
Persistence and Degradability: Moderately biodegradable, expected to degrade under environmental conditions, product not intended for release to natural systems
Bioaccumulation Potential: Not expected to bioaccumulate in aquatic organisms
Mobility in Soil: Moderate, will move with water but adsorbs to organic matter
Other Adverse Effects: Avoid unintentional release; long-term environmental effects poorly studied
Disposal Methods: Dispose in accordance with local, regional, national, and international regulations, incineration preferred if available
Waste Handling: Seal in tightly closed, labeled container, avoid release into the environment
Contaminated Packaging: Clean containers can be recycled, otherwise treat as hazardous waste
