Name: Tin(II) Chloride Dihydrate
Chemical Formula: SnCl2·2H2O
Synonyms: Stannous chloride dihydrate
Appearance: White to colorless crystalline solid
Odor: Odorless
Main hazards: Causes skin and eye irritation; harm if swallowed; inhalation of dust may irritate respiratory tract
Classification: Corrosive to eyes and skin; harmful substance
Signal Word: Warning
Risk statements: Prolonged or repeated contact increases chances of severe burns; acute exposure raises risk for respiratory issues
Chemical: Tin(II) Chloride Dihydrate
CAS Number: 10025-69-1
Percentage: More than 95% as pure material
Impurities: Trace levels of insolubles sometimes present from manufacturing, not usually significant for toxicity or safety
Inhalation: Remove exposed person to fresh air right away; seek medical attention for symptoms
Skin contact: Wash area with plenty of water and gentle soap; remove contaminated clothing
Eye contact: Flush eyes with lots of water for at least 15 minutes; get medical help as effects on eyes can be severe
Ingestion: Rinse mouth; seek prompt medical advice; do not induce vomiting without instructions from poison control
Suitable extinguishing agents: Use water spray, dry chemical, foam, or carbon dioxide
Specific hazards: Material itself does not burn, but containers may decompose in fire giving off irritating or corrosive gases such as hydrochloric acid fumes
Protective equipment: Wear full protective gear and self-contained breathing apparatus during firefighting; avoid inhaling fumes
Personal precautions: Ventilate area; keep unprotected people away; put on protective gloves, goggles, and mask
Spill cleanup: Use inert absorbent material; sweep or scoop into a suitable container; avoid dust formation; wash area with water soon after
Disposal: Follow proper hazardous waste procedures; don’t wash down the drain if possible, since waste water contamination is real
Handling tips: Wear gloves, goggles, and lab coat; use only with proper ventilation; avoid creating or breathing dust
Storage needs: Keep in cool, dry area; containers kept tightly closed; store separately from strong oxidizers and sources of moisture
Safe work habits: Always wash hands after handling; don’t eat or drink near chemical storage or work
Engineering controls: Work under local exhaust or in a fume hood; keep airborne levels down
Personal protective equipment: Gloves made of polyethylene or butyl rubber, chemical safety goggles, lab coat, and mask if dust may form
Respiratory protection: Use NIOSH-approved respirator if exposure exceeds guidelines; better safe than sorry in dusty areas
Hygiene: Change contaminated clothes; wash up thoroughly afterward; eye wash and safety shower should be close by
State: Solid at room temperature
Color: Colorless to white
Solubility: Easily dissolves in water
Melting point: Loses water and decomposes instead of melting cleanly
Boiling point: Not applicable, breaks down at high temperature
Smell: No recognizable odor
Density: About 2.71 g/cm³
Chemical stability: Stable if kept dry, reacts with moist air to form hydrochloric acid fumes
Incompatible materials: Strong acids, oxidizing agents, and alkalis create dangerous reactions; avoid contact
Hazardous reactions: Fumes of tin oxides and hydrogen chloride can form during decomposition or heating
Routes of exposure: Breathing dust, skin or eye contact, swallowing
Short-term symptoms: Eye, nose, and throat irritation, burning or stinging on skin, stomach upset
Long-term risks: Repeated exposure may increase risk to lungs and mucous membranes; no solid proof for cancer risk with this compound
Medical experience: Reports of strong skin and eye burns in accidental exposures; low levels can build up and cause sensitivity in some people
Environmental risks: Toxic to aquatic life in moderate concentrations; could harm animal and plant life in water bodies
Degradability: Tin compounds tend to stick around in soil and water; breakdown is slow
Bioaccumulation: Some potential for tin to build up in aquatic organisms, though not as severe as heavy metals like mercury
Disposal: Treat as hazardous chemical waste; don’t put it in the regular trash or down the sink
Reuse and recycling: Some facilities may offer chemical recovery for large amounts
Legal rules: Follow local and national rules about hazardous chemical disposal, as fines and environmental risks come with improper dumping
Shipping regulations: Not regulated as a dangerous good in small packages, but safe transport practices always matter
Packing: Use sealable, chemical-resistant containers; avoid leaks by double-bagging or extra seals
Spill emergencies: Secure containers during transit; label contents clearly for handlers to know risks
Workplace rules: Covered by chemical workplace hazard laws in most countries
Labeling: Packages need labels with bleach symbol (corrosive), health risks, and basic handling advice
Restrictions: Special restrictions may apply for use in schools, labs, and some industries to protect staff and students
Right-to-Know laws: Workers deserve information about risks and should receive safety training as part of the job
