USES/FORMS/SOURCES

USES

Tin (IV) Oxide is used as a colorant and opacifying agent in glass, ceramic glazes and enamels; as a polishing powder or paste for glass, metals and gems; as a mordant for dyeing textiles; and as a catalyst. It is also used in cosmetics and perfume preparations, tin salts, electrical resistor insulating film, and sintered electrodes (Ashford, 1994; Budavari, 1996; Lewis, 1993). Tin (IV) oxide may be used in conductive coatings and for adhesion of dental ceramics (HSDB, 1997).

FORMS

Commercial grades of Tin (IV) oxide are: white, pure; white; gray; chemically pure; 99.9% and 99.999% pure (Lewis, 1993).

-CLINICAL EFFECTS

GENERAL CLINICAL EFFECTS

Signs and symptoms may result from inhalation and skin or eye contact. A benign pneumoconiosis (stannosis), dyspnea, or decreased pulmonary function may occur following chronic inhalation exposure. Fume exposure may be more likely to cause these effects than dust exposure.

POTENTIAL HEALTH HAZARDS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 171 (ERG, 2004)

Inhalation of material may be harmful.
Contact may cause burns to skin and eyes.
Inhalation of Asbestos dust may have a damaging effect on the lungs.
Fire may produce irritating, corrosive and/or toxic gases.
Some liquids produce vapors that may cause dizziness or suffocation.
Runoff from fire control may cause pollution.

-MEDICAL TREATMENT

LIFE SUPPORT

Support respiratory and cardiovascular function.

SUMMARY

FIRST AID - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 171 (ERG, 2004)

Move victim to fresh air.
Call 911 or emergency medical service.
Give artificial respiration if victim is not breathing.
Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes.
In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves.

FIRST AID

FIRST AID

EYE EXPOSURE - Immediately wash the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately. Contact lenses should not be worn when working with this chemical.
INHALATION EXPOSURE - Move the exposed person to fresh air at once. Other measures are usually unnecessary.
TARGET ORGANS - Respiratory system (National Institute for Occupational Safety and Health, 2007).

GENERAL

Move victims of inhalation exposure from the toxic environment and administer 100% humidified supplemental oxygen with assisted ventilation as required. Exposed skin and eyes should be copiously flushed with water. Ingestion may result in significant esophageal or gastrointestinal tract irritation or burns, and EMESIS SHOULD NOT BE INDUCED. Cautious gastric lavage followed by administration of activated charcoal may be of benefit if the patient is seen soon after the exposure.

INHALATION EXPOSURE

INHALATION: Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with an inhaled beta2-adrenergic agonist. Consider systemic corticosteroids in patients with significant bronchospasm.
If bronchospasm and wheezing occur, consider treatment with inhaled sympathomimetic agents.

DERMAL EXPOSURE

DECONTAMINATION: Remove contaminated clothing and jewelry and place them in plastic bags. Wash exposed areas with soap and water for 10 to 15 minutes with gentle sponging to avoid skin breakdown. A physician may need to examine the area if irritation or pain persists (Burgess et al, 1999).
Treat dermal irritation or burns with standard topical therapy. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines.

EYE EXPOSURE

DECONTAMINATION: Remove contact lenses and irrigate exposed eyes with copious amounts of room temperature 0.9% saline or water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist after 15 minutes of irrigation, the patient should be seen in a healthcare facility.

-ENVIRONMENTAL HAZARD MANAGEMENT

POLLUTION HAZARD

The mineral form of Tin (IV) oxide (cassiterite) can occur in rock veins connected with granite and acid eruptive rocks. Although, the majority of this mineral comes from alluvial deposits. Tin salts may be contained in waste streams from production of tin cans and effluent from industrial processes. Therefore, tin salts may reach ground and surface waters. As most tin salts are insoluble in water, they are not likely to remain in solution under most conditions (HSDB, 1997).

ENVIRONMENTAL FATE AND KINETICS

WATER

SURFACE WATER
- Most tin salts are insoluble in water and are not likely to remain in solution under most conditions (HSDB, 1997).

SOIL

TERRESTRIAL
- Tin oxides are generally insoluble in soils (HSDB, 1997).

BIOACCUMULATION

BIOCONCENTRATION FACTOR

At neutral to alkaline pH, tin is insoluble, so bioconcentration in the food chain is unlikely (HSDB, 1997).

ENVIRONMENTAL TOXICITY

No information found at the time of this review.

-PHYSICAL/CHEMICAL PROPERTIES

MOLECULAR WEIGHT

150.69

DESCRIPTION/PHYSICAL STATE

SOLUBILITY

IN WATER

Tin (IV) oxide is insoluble in cold or hot water (Ashford, 1994; Budavari, 1996) HSDB, 1997; (Lewis, 1993)

IN ORGANIC SOLVENTS

Tin (IV) oxide is insoluble in alcohol (Budavari, 1996).

OTHER

Tin (IV) oxide is insoluble in cold acids, but is slowly soluble in hot concentrated sodium or potassium hydroxide. (Budavari, 1996). Lewis reports that tin (IV) oxide is soluble in concentrated sulfuric and hydrochloric acid (Lewis, 1993).
