General Description
White TIN is an almost silver-white, ductile, malleable, lustrous solid. mp 232°C, bp: 2507°C. Density: 7.3 g/cm3. Pure white tin becomes non-metallic powdery gray tin if held for a sustained period at temperatures less than 13°C.

Health Hazard
Excerpt from NIOSH Pocket Guide for Tin:

Exposure Routes: Inhalation, skin and/or eye contact

Symptoms: Irritation eyes, skin, respiratory system; In Animals: vomiting, diarrhea, paralysis with muscle twitching

Target Organs: Eyes, skin, respiratory system (NIOSH, 2023)
Reactivity Profile
TIN is a reducing agent. Stable in massive form in air, but oxidizes (corrodes) in air as a powder, especially in the presence of water. Dissolve slowly in dilute strong acids in the cold. Dissolves in hot aqueous KOH and other strongly basic solutions. Incompatible with acids and base. Incompatible with chlorine and turpentine.
Belongs to the Following Reactive Group(s)

First Aid
Excerpt from NIOSH Pocket Guide for Tin:

Eye: IRRIGATE IMMEDIATELY - If this chemical contacts the eyes, immediately wash (irrigate) the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately.

Skin: SOAP WASH IMMEDIATELY - If this chemical contacts the skin, immediately wash the contaminated skin with soap and water. If this chemical penetrates the clothing, immediately remove the clothing, wash the skin with soap and water, and get medical attention promptly.

Breathing: RESPIRATORY SUPPORT - If a person breathes large amounts of this chemical, move the exposed person to fresh air at once. If breathing has stopped, perform artificial respiration. Keep the affected person warm and at rest. Get medical attention as soon as possible.

Swallow: MEDICAL ATTENTION IMMEDIATELY - If this chemical has been swallowed, get medical attention immediately. (NIOSH, 2023)
