Inhalation: Move person to fresh air immediately, keep individual at rest, seek medical attention for respiratory symptoms, supply oxygen if breathing is difficult
Skin Contact: Remove contaminated clothing, rinse affected area with copious amounts of water for at least 15 minutes, do not use solvents or thinners, seek medical advice if irritation persists
Eye Contact: Flush eyes with lukewarm, gently flowing water for at least 20 minutes, remove contact lenses if present and easy to do, seek immediate ophthalmologic evaluation
Ingestion: Rinse mouth thoroughly, never induce vomiting, do not give anything by mouth to an unconscious person, consult a physician urgently
Suitable Extinguishing Media: Use dry chemical powder, carbon dioxide, or foam, do not use water jets directly on fire
Specific Hazards: Combustion evolves toxic fumes such as oxides of nitrogen, hydrogen chloride, and phosgene, containers may burst if heated
Protective Equipment: Firefighters wear self-contained breathing apparatus and full protective gear, avoid inhalation of combustion products, cool surroundings with water spray to prevent rupture
Personal Precautions: Evacuate area, ventilate location, restrict access to necessary personnel only, wear chemical-resistant gloves and eye protection
Environmental Precautions: Prevent entry into sewers, drains, water sources, notify authorities if significant spill occurs
Clean-Up Methods: Absorb with inert material such as sand or vermiculite, place in a secure chemical waste container, decontaminate area with dilute acid solution, thoroughly ventilate contaminated zone
Handling: Handle under chemical fume hood, avoid contact with skin, eyes, and clothing, use proper personal protective equipment, do not breathe vapors or dust, keep containers closed when not in use
Storage: Store tightly sealed in a cool, dry, well-ventilated area, keep away from heat, sparks, open flames, segregate from incompatible chemicals such as strong acids, bases, and reducing agents, label storage area clearly
Engineering Controls: Employ local exhaust ventilation, utilize closed process systems to prevent exposure, ensure safety showers and eye wash stations are accessible
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile or neoprene), lab coat, goggles or face shield, respiratory protection if airborne exposure exceeds acceptable limits
Occupational Exposure Limits: No established occupational exposure limits, maintain exposure as low as reasonably achievable

Symptoms of Overexposure: Burning sensation, coughing, wheezing, headache, skin blistering, vision impairment, possible pulmonary edema in severe inhalation cases
Sensitization: Risk of allergic reaction with repeated contact
Aquatic Toxicity: Toxic to aquatic life, acute and chronic effects observed in fish and invertebrates
Persistence and Degradability: Degradation slow under normal environmental conditions, persistent in soil and water
Bioaccumulation: Potential for moderate accumulation in aquatic organisms
Mobility in Soil: Low to moderate mobility, adsorbs to soil particles
Other Adverse Effects: Hazardous to the ecosystem with direct release, prevent product and waste from entering watercourses
Waste Treatment Methods: Dispose as hazardous waste in accordance with local, regional, and national regulations, incineration preferred with emission cleaning
Contaminated Packaging: Rinse containers with approved neutralizer, dispose of in accordance with hazardous waste protocol
Special Precautions: Do not release residue or rinsate to the environment, perform all disposal at licensed facility
