First Aid Measures

Inhalation: Move affected person to fresh air, monitor for respiratory distress, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, flush skin with soap and water for several minutes; medical advice for irritation
Eye Contact: Rinse cautiously with water for at least 15 minutes; remove contact lenses, seek ophthalmologist if irritation continues
Ingestion: Rinse mouth thoroughly with water, do not induce vomiting, seek immediate medical care in case of pain or persistent discomfort

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Unsuitable Extinguishing Media: Direct water jets may spread powder
Specific Hazards: May decompose at high temperature, emitting toxic fumes such as nitrogen oxides and carbon oxides
Protective Equipment: Firefighters wear self-contained breathing apparatus and full protective gear for chemical fires
Firefighting Instructions: Cool fire-exposed containers with water spray, avoid inhaling smoke, isolate area

Accidental Release Measures

Personal Precautions: Use respiratory protection, avoid dust formation, employ suitable gloves and chemical goggles
Environmental Precautions: Prevent entry into drains, waterways, soil
Methods for Cleaning Up: Sweep or vacuum up spilled material carefully without creating dust, transfer to suitable closed containers for disposal, ventilate area, wash spill site after material pick-up is complete

Handling and Storage

Handling: Wear personal protective equipment, avoid inhaling dust or vapors, prevent contact with eyes or skin, use only in well-ventilated areas, keep away from ignition sources
Storage: Store in tightly closed containers, in a cool, dry, silver-foil-protected place away from light, incompatible chemicals, moisture, and heat sources, use secondary containment for large quantities

Exposure Controls and Personal Protection

Control Parameters: No occupational exposure limit values established
Engineering Controls: Work in fume hood or use local exhaust, maintain good general ventilation
Personal Protective Equipment: Chemical-resistant gloves (nitrile or PVC), safety goggles, laboratory coat, respirator if ventilatory controls inadequate
Hygiene Measures: Wash hands after handling, remove contaminated clothing, do not eat, drink or smoke in work area, decontaminate equipment and work surfaces after use

Incompatible Materials: Strong oxidants, strong alkalis, reducing agents
Hazardous Decomposition Products: May emit toxic nitrogen oxides, carbon oxides if combusted or decomposed
Possibility of Hazardous Reactions: No violent reactivity with expected lab reagents but caution near incompatible chemicals

Toxicological Information

Acute Toxicity: Data limited or not available; analogs suggest low oral and dermal toxicity in rodents
Skin Corrosion/Irritation: May cause mild irritation upon prolonged contact
Serious Eye Damage/Irritation: May produce mild redness or watering
Respiratory Issues: Dust or powder may irritate upper respiratory tract
Germ Cell Mutagenicity, Carcinogenicity: No data available, not recognized as mutagenic or carcinogenic based on available structural analogy
Reproductive Toxicity: No findings available
Target Organ Effects: No organ-specific toxicity identified in literature
Chronic Effects: No long-term studies found for repeated exposure; prudent to minimize chronic exposure

Ecological Information

Ecotoxicity: Data unavailable for aquatic or terrestrial environments; analog compounds show low acute toxicity
Persistence and Degradability: Not readily degradable; slow breakdown in soil and water suspected
Bioaccumulation: Low potential for bioaccumulation due to low log Kow, water solubility
Mobility in Soil: Expected to exhibit some mobility in aquatic environments owing to water solubility
Other Adverse Effects: No known ozone depletion or hazardous atmospheric effects

Disposal Considerations

Waste Treatment Methods: Handle and discard as laboratory chemical waste; incineration in permitted facility recommended, follow local, regional, and national waste management regulations
Disposal of Containers: Rinse residue out with a compatible solvent, dispose of containers as hazardous waste
Contaminated Packaging: Empty containers or liners may retain traces, must be managed as hazardous material
