First Aid Measures

General Measures: Seek immediate medical attention in case of severe or persistent symptoms. Move affected person away from exposure source.
Inhalation: Go outdoors or to fresh air, keep at rest, and monitor for symptoms. If breathing difficulties persist, call a physician or emergency services.
Skin Contact: Wash skin thoroughly with soap and water for no less than 15 minutes. Remove contaminated clothing and launder before re-use.
Eye Contact: Rinse cautiously with clean water for several minutes, frequently lifting upper and lower eyelids. Seek medical attention if irritation remains.
Ingestion: Rinse mouth with water. Do not induce vomiting unless trained to do so. Consult qualified medical personnel and provide product label when available.
Most Important Symptoms: Irritation or burning sensation on contact areas. Vomiting, nausea, sweating, shortness of breath, or visual changes may indicate significant exposure.

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical powder, foam, carbon dioxide (CO₂), or water spray
Unsuitable Extinguishing Media: Avoid direct water jets on burning product to prevent spreading
Specific Hazards: Thermal decomposition produces hazardous gases including hydrogen bromide, carbon monoxide, carbon dioxide, and nitrogen oxides.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus (SCBA) and chemical protective clothing rated for toxic and corrosive fumes.
Firefighting Instructions: Evacuate surrounding area, cool surrounding containers, fight fire from upwind, and avoid inhaling fumes or smoke.
Explosion Data: Not classified as explosive; no known risk of dust eruptions under normal handling

Accidental Release Measures

Personal Precautions: Put on protective goggles, gloves, and a laboratory coat. Evacuate unprotected personnel and ventilate the area.
Environmental Precautions: Prevent product from entering drains, watercourses, or soil to minimize local environmental impact.
Containment Methods: Block spread with inert absorbing materials such as sand, earth, or commercial spill pads.
Cleanup Methods: Scoop or shovel spillage into clearly labelled chemical waste bins. Wash spill site with soap and water after collection. Dispose of according to local regulations.
Special Procedures: Handle all cleanup and waste as hazardous material, following site-specific emergency protocol.

Handling and Storage

Handling Practices: Work in a chemical fume hood or well-ventilated area. Avoid direct skin and eye contact. Do not inhale powders or vapors. Use appropriate lifting techniques when transferring solid forms.
Hygiene Measures: Wash hands and face before meals, breaks, and at end of shift. Keep work clothing separate from street clothes.
Storage Conditions: Keep container sealed in a cool, dry, and well-ventilated location. Store away from direct sunlight, heat, acids, and oxidizers.
Incompatible Materials: Strong acids, strong bases, oxidizing agents. Reactivity increases in presence of open flames or strong heat sources.
Container Requirements: Use tightly closed, corrosion-resistant containers with proper chemical labelling. Secondary containment is preferred for bulk storage.

Exposure Controls and Personal Protection

Control Parameters: No established occupational exposure limits in standard regulatory databases (as of latest revision)
Engineering Controls: Local exhaust ventilation and/or fume hoods. Eye wash stations and emergency showers should remain accessible.
Personal Protective Equipment: Chemical splash-resistant goggles, lab coat, chemical-resistant gloves (nitrile, butyl rubber), and closed-toe shoes.
Respiratory Protection: Use a dust or mist respirator if airborne concentrations exceed recommended exposure levels. Fit tested masks for routine work in poorly ventilated zones.
Environmental Controls: Prevent accidental release by sealing containers after use and checking for leaks as part of regular maintenance.

Toxicological Information

Acute Toxicity: Documented animal studies indicate an oral LD50 in rats between 400 and 800 mg/kg. High exposure causes gastrointestinal effects, central nervous system depression, and localized irritation.

Ecological Information

Aquatic Toxicity: Toxic to aquatic life at moderate to high concentrations. LC50 for freshwater fish ranges from 3-15 mg/L based on analog ionic liquids.
Persistence and Degradability: Not easily degradable in the environment; relies on advanced oxidation processes for breakdown.
Bioaccumulation Potential: Low to moderate bioaccumulative potential; monitoring of water bodies recommended near discharge sites.
Mobility in Soil: Highly mobile in aqueous media, especially in sandy or gravel soils
Other Adverse Effects: Large accidental releases pose risk to aquatic microorganisms and may alter ecosystem balance until diluted or cleaned up.
Conclusion for Environmental Risk: Limit discharge to controlled facilities and ensure environmental risk assessments for new sites.

Disposal Considerations

Safe Handling for Disposal: Package waste in suitable, leak-proof chemical containers with appropriate labeling for hazardous waste transport.
Disposal Methods: Forward to licensed hazardous waste disposal company. Never dispose in normal municipal waste or directly into the natural environment.
Incineration: Favor high-temperature controlled incineration with flue gas scrubbing to remove acid gases.
Precautions for Incineration: Inform operators about corrosive and toxic gases released at decomposition.
Legal Framework: Adhere to national and local hazardous waste management regulations and keep detailed logs of waste quantities and ultimate disposal sites.
