Inhalation: Move affected person to fresh air, support breathing with oxygen if necessary, seek medical attention if irritation persists
Skin Contact: Wash skin thoroughly with soap and water for at least 15 minutes, remove contaminated clothing, call a physician if redness, burning, or discomfort remains
Eye Contact: Rinse eyes carefully with water for several minutes, remove contact lenses if present, continue rinsing, consult an eye specialist in cases of persistent irritation
Ingestion: Do not induce vomiting, rinse mouth with clean water, seek immediate medical help, and provide the chemical’s safety information to responders
General Advice: Always provide medical personnel with information on the substance; collect all containers and packaging for reference.
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, or foam extinguishers preferred for small fires, do not use a solid water stream directly on substance
Specific Hazards: May decompose under fire conditions to form toxic gases including nitrogen oxides, carbon monoxide, bromide fumes
Protective Equipment: Firefighters require self-contained breathing apparatus and full body protection against chemical splashes and vapors
Special Procedures: Cool exposed containers with water spray from a safe distance, prevent fire water runoff from entering waterways or sewer systems; trained teams should handle large spills or fire-related releases.
Personal Precautions: Use chemical-resistant gloves, goggles, lab coats, employ local exhaust ventilation where possible, avoid inhaling dust or direct contact
Spill Cleanup Methods: Sweep up the material, avoid creating dust, transfer waste into a tightly sealed, appropriately labeled chemical waste container
Environmental Precautions: Prevent release into the environment, do not allow material to enter drains, surface water, or soil
Decontamination: Wash contaminated surfaces with plenty of water, ventilate affected area, discard cleanup materials and PPE according to hazardous waste disposal rules
Handling: Work in a well-ventilated space, wear protective equipment such as chemical gloves, eye protection, and a lab coat, keep containers tightly closed, avoid inhalation and skin or eye contact
Storage: Store in a dry and cool area, protect from moisture and incompatible chemicals including strong oxidizers, acids, and bases, never store near food or animal feed
Specific Storage Needs: Use corrosion-resistant shelving, post appropriate hazard signage, secure shelves against earthquake risk or accidental bumping
Container Guidelines: Use only manufacturer-recommended packaging, make sure all containers bear correct labeling and hazard information.
Engineering Controls: Use local exhaust fume hoods, closed transfer systems or glove boxes if handling large quantities, regular air monitoring to detect vapor or dust
Personal Protective Equipment: Chemical-resistant gloves (nitrile, butyl rubber), safety goggles or a face shield, disposable lab coats or aprons, closed-toe shoes
Respiratory Protection: In the absence of engineered ventilation, wear an approved respirator fitted with organic vapor and particulate filters
Exposure Limits: No occupational exposure limits specifically established, maintain airborne levels as low as possible
Hygiene Measures: Wash hands thoroughly after handling, change gloves or protective clothing before eating or smoking
Appearance: White to off-white crystalline powder
Odor: Mild, slightly amine-like
pH: Neutral to slightly acidic in solution
Melting Point: 80-90°C
Boiling Point: Not available, decomposes before reaching boiling
Solubility: Highly soluble in water, ethanol, and most polar solvents
Flash Point: Not readily flammable under normal laboratory conditions
Vapor Pressure: Negligible at room temperature
Density: 1.18 g/cm³ at 25°C
Partition Coefficient: No significant data, low potential for bioaccumulation noted.
Chemical Stability: Stable in closed containers under recommended storage conditions
Reactivity: Not particularly reactive under ambient conditions
Incompatible Materials: Strong oxidizing agents, concentrated acids and bases, reducing agents may cause dangerous reactions
Decomposition Products: Heating or incineration produces toxic gases including bromine compounds, nitrogen oxides, possible carbon oxides
Hazardous Polymerization: No hazardous polymerization reported in laboratory experience.
Acute Toxicity: Moderately toxic by ingestion, LD50 (oral, rat) not widely published but estimated in the range 250-1000 mg/kg
Skin Irritation: Potential to cause redness, burning, irritation, or allergic response with prolonged or repeated contact
Eye Irritation: May cause pain, redness, tearing, and blurred vision
Respiratory Irritation: Breathing dust can cause coughing or nasal irritation, avoid inhalation of even small quantities
Chronic Effects: No evidence of carcinogenicity or mutagenicity reported, chronic exposure may cause dermatitis or respiratory symptoms
Additional Data: No clear data available on reproductive toxicity or specific target organ toxicity.
Aquatic Toxicity: Harmful to aquatic organisms, especially in concentrated spills, insufficient chronic aquatic toxicity data for full risk assessment
Persistence and Degradability: Likely to persist in the environment due to ionic nature, does not readily biodegrade
Bioaccumulation: Low bioaccumulation expected owing to high water solubility
Soil Mobility: Highly mobile in water, may leach into groundwater in large accidental releases
Other Adverse Effects: Avoid any release to aquatic systems, report significant discharges to local authorities.
Waste Treatment Methods: Treat as hazardous chemical waste, incinerate in a chemical incinerator equipped to handle halogenated compounds, avoid landfills
Container Disposal: Triple rinse empty containers with water, destroy labels before discarding, follow local hazardous waste disposal regulations
Do Not: Pour down drains, release into the environment, or mix with regular trash.
UN Number: Not regulated as hazardous for transport by air, sea, or road under most local or international regulations
Proper Shipping Name: Chemical not classified as dangerous according to current DOT, IATA, or IMDG guidelines
Packing Group: Typically not assigned, confirm with the shipper
Special Precautions: Clearly label packages, ship in tightly sealed containers, prevent package leaks or spills, comply with all local transport safety practices.
U.S. TSCA: Listed or exempt
EU REACH: Chemical registration may be required for large-scale imports or uses
OSHA: Not listed as a specifically regulated substance, general hazard communication requirements apply
WHMIS Canada: Controlled product according to Canadian regulations
Other Regulatory Information: Always consult the latest versions of country-specific chemical safety regulations, notify competent authorities in case of accidental large-scale release.
