Chemical Name: Tin Tetrabromide
Chemical Family: Inorganic Metal Halide
Component: Tin tetrabromide – 100%
Impurities: No significant impurities that affect hazard classification
Molecular Weight: 438.34 g/mol
Physical Form: Solid, usually as colorless crystals
Inhalation: Move exposed person to fresh air, seek medical help if breathing difficulty occurs
Skin Contact: Wash with plenty of running water, remove contaminated clothing, continue flushing skin for at least 15 minutes, seek medical attention for persistent irritation or burns
Eye Contact: Flush eyes immediately with water for no less than 15 minutes, keeping eyelids open, get medical help promptly
Ingestion: Rinse mouth, seek medical advice, avoid inducing vomiting unless directed by a physician
Most Symptoms: Blistering, severe eye discomfort, irritation to nose and lungs if inhaled
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, or appropriate foam
Unsuitable Extinguishing Media: Do not use water directly on substance
Fire Hazards: Releases toxic and corrosive fumes (hydrogen bromide, tin oxides) if exposed to heat or flames
Protective Equipment: Wear full protective gear and self-contained breathing apparatus
Special Procedures: Stay upwind, isolate hazard area, use water spray only to cool nearby containers, avoid inhaling combustion gases
Personal Precautions: Avoid breathing vapors or dust, wear gloves, safety goggles, and a fitted respirator
Environmental Precautions: Prevent spread to drains, soil, and waterways, contain spill using sand or inert absorbent
Methods for Clean-Up: Sweep up or scoop spilled material into sealed containers, ventilate area, do not touch or walk through spilled substance, dispose as hazardous waste
Decontamination: Clean spill surfaces thoroughly after removal and ventilate area
Handling: Work in a chemical fume hood or well-ventilated space, avoid formation of dust, do not breathe dust or vapors, wash hands after handling, avoid contact with skin, eyes, and clothing
Storage: Keep in tightly sealed, corrosion-resistant container, store away from moisture, acids, oxidizers, and incompatible chemicals, maintain a cool, dry, and ventilated area, keep out of direct sunlight and away from sources of ignition, label container clearly and lock storage area if possible
Exposure Limits: No established OSHA or ACGIH exposure limit for stannic bromide, but control dust and fumes to lowest possible concentration
Engineering Controls: Use laboratory fume hood, local exhaust, showers, eyewash stations
Personal Protection: Wear chemical-resistant gloves (nitrile, neoprene), safety goggles or face shield, long-sleeved lab coat, appropriate mask or respirator (P2 or better) under conditions with possible dust generation
Hygiene: No eating, drinking, or smoking in work area, wash hands before breaks and after use, launder work clothes frequently
Appearance: Colorless, crystalline solid
Odor: Sharp, irritating, similar to hydrogen bromide
Odor Threshold: Not determined
Melting Point: 31°C (87.8°F)
Boiling Point: 201°C (394°F)
Density: 3.47 g/cm3
Solubility: Reacts with water, decomposes
Vapor Pressure: Data not available
pH: Not applicable
Partition Coefficient: Not applicable
Evaporation Rate: Not available
Flammability: Not flammable under standard conditions
Chemical Stability: Stable under recommended storage, reacts with moisture or water, decomposes quickly with release of hydrogen bromide
Reactivity: Corrosive to metals including steel and aluminum, forms acidic and toxic vapors on contact with water
Hazardous Reaction: Will not polymerize, but hazardous exothermic reaction may occur with water or oxidizers
Incompatible Materials: Strong oxidizing agents, water, moisture, strong bases, some metals
Decomposition Products: Hydrogen bromide gas, bromine, tin oxides
Acute Toxicity: Harmful by inhalation, ingestion or skin contact, may be fatal if swallowed in large quantities
Skin Corrosion/Irritation: Causes burns and blistering on contact
Eye Damage/Irritation: Causes severe eye damage with redness, pain, clouding, possible permanent injury
Respiratory Effects: Dust or fumes can cause inflammation of nose, throat, lungs with cough, shortness of breath
Chronic Exposure: May aggravate existing skin, respiratory, or eye conditions, prolonged contact may lead to chronic bronchitis
Carcinogenicity: Not listed by IARC, NTP, or OSHA
Sensitization: No confirmed data for allergic skin or respiratory sensitization
Ecotoxicity: Very toxic to aquatic life, lethal to fish and invertebrates at low concentrations
Persistence and Degradability: Hydrolyzes in water to form tin oxides and free bromide ions, both can persist in environment
Bioaccumulation: Tin tends not to bioaccumulate, bromide ions disperse in water
Mobility: Highly mobile in water; quickly alters chemical forms
Other Adverse Effects: Alters water pH and can affect natural ecosystems, do not allow to reach water bodies or sewage system
Waste Disposal: Separate as hazardous waste, follow local regulations
Recommended Treatment: Store in sealed, labeled container for collection by licensed chemical waste disposal contractor
Do Not: Flush to drain, landfill, or incinerate without appropriate controls and permissions
Contaminated Packaging: Should be treated as hazardous, decontaminate or dispose as per chemical waste regulations
