Other Ingredients: None reported as hazardous
Molecular Weight: 173.17 g/mol
Inhalation: Remove affected person to fresh air, keep comfortable and warm, give oxygen if breathing is difficult, seek medical attention promptly
Skin Contact: Remove contaminated clothing and rinse skin thoroughly with running water for at least 20 minutes, use mild soap, get immediate medical advice for persistent irritation
Eye Contact: Rinse opened eyes cautiously with water for at least 15 minutes, remove contact lenses if present and easy to do, call for urgent medical help
Ingestion: Rinse out mouth with water, never induce vomiting unless directed by a professional, seek medical attention quickly, show the label or SDS to responders
Self-Protection of Rescuer: Use gloves and goggles, avoid direct exposure, use barrier resuscitation if mouth-to-mouth required
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, or water spray
Unsuitable Media: High-pressure water jets risk spreading contaminated material
Specific Hazards: Decomposes on heating to release toxic gases including nitrogen oxides and carbon oxides, risk of explosive dust-air mixtures
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective suit
Further Information: Stay upwind, keep out unnecessary personnel, cool containers with water if exposed to flames
Personal Precautions: Wear chemical-resistant gloves, eyewear, and suitable protective clothing; avoid contact with skin and eyes; prevent inhalation
Environmental Precautions: Keep material out of drains and watercourses; inform relevant authorities in case of contamination; use dikes to contain spillage
Methods for Clean-up: Collect with inert absorbent (vermiculite, sand), place in chemical waste container, ventilate area, decontaminate surfaces with mild detergent, dispose according to regulations
Large Spill: Evacuate area, use spark-proof tools and explosion-proof equipment
Handling: Use local exhaust ventilation, minimize dust formation, avoid inhaling dust or fumes, wear appropriate PPE, wash hands thoroughly after handling
Storage: Store in a cool, dry, well-ventilated area, away from sources of ignition, keep tightly closed in original container, store separately from oxidizing agents and strong acids, regular inspection for leaks or damage
Precautions: Avoid direct sunlight and moisture, label all containers clearly, keep out of reach of unauthorized personnel
Occupational Exposure Limits: No specific OSHA or ACGIH/TLV limits, minimize exposure as much as possible
Engineering Controls: Local exhaust ventilation, process enclosure, eyewash stations and safety showers nearby
Personal Protection: Chemical-resistant gloves (nitrile or neoprene), splash-proof goggles, lab coats or aprons, approved dust mask or respirator in case of inadequate ventilation
Hygiene Measures: Avoid eating, drinking, or smoking in work area, wash hands before breaks and after finishing work, remove contaminated clothing immediately

Skin Irritation: Causes moderate to severe irritation, possible sensitization after repeated exposure
Eye Irritation: Severe irritation, risk of corneal injury
Inhalation Effects: Short-term exposure causes headache, dizziness, possible respiratory distress
Chronic Effects: Prolonged exposure may cause damage to blood, liver, and kidneys, possible mutagenic effects based on animal data
Carcinogenicity: Not classified by IARC, OSHA, NTP; some evidence of mutagenic and carcinogenic concerns in animal studies
Other Effects: Blue tint to skin (cyanosis) after significant exposure, possible allergic contact dermatitis
Aquatic Toxicity: Acute toxic to aquatic life, LC50 (96hr, fish): 2-10 mg/L
Persistence and Degradability: Not readily biodegradable, persists in soil and water
Bioaccumulation: Moderate potential to bioaccumulate in aquatic organisms, log Kow suggests movement into fatty tissues
Mobility in Soil: Low solubility limits transport, but may move in particulate-bound form
Other Adverse Effects: Long-term contamination risks in ecosystems, may disrupt aquatic food chains
Waste Treatment Methods: Dispose of contents and containers through licensed chemical waste contractor
