Special Firefighting Procedures:  Firefighters must wear full face, self-contained breathing apparatus and full protective clothing to prevent contact with skin and eyes.  Fumes from fire are hazardous.  Isolate runoff  to prevent environmental pollution.

Unusual Fire & Explosion Hazard:  May emit toxic fumes if thermally decomposed.

V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of tin sulfate have not been thoroughly investigated and recorded.

Tin compounds have variable toxicity.  Elemental tin and inorganic tin compounds have low toxicity and are poorly absorbed when ingested.  Some inorganic tin salts are irritating or can liberate toxic fumes on decomposition.  The latter is particularly true of tin halogens.  (Sax, Dangerous Properties of Industrial Materials)

Sulfates have variable toxicity.  In general the toxic properties of substances containing the sulfate radical is that the materials (cation) with which the sulfate (anion) is combined.  (Sax, Dangerous Properties of Industrial Materials)

Acute Effects:

Inhalation:  May cause irritation to the nose and throat.

Ingestion:  May cause gastrointestinal irritation.

Skin:  May cause irritation.

Eye:  May cause irritation.

Chronic Effects:

Inhalation:  Prolonged or repeated exposure may cause pneumoconiosis.

Ingestion:  No chronic health effects recorded.

Skin:  No chronic health effects recorded.

Eye:  No chronic health effects recorded.

Target Organs:  May affect the eyes, skin and respiratory system.

Medical Conditions Generally Aggravated by Exposure:  Pre-existing respiratory disorders.

Carcinogenicity:  NTP:  No IARC:  No             OSHA:  No

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove victim to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek medical attention.

INGESTION: Give 1-2 glasses of milk or water and induce vomiting, seek medical attention.  Never induce vomiting or give anything by mouth to an unconscious person.

SKIN:  Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water.  Seek medical attention if symptoms persist.

EYES:  Flush with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes.  Seek medical attention if symptoms persist.

VII.   SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled:  Wear appropriate respiratory and protective equipment specified in section VIII.  Isolate spill area and provide ventilation.  Scoop up or vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal.  Take care not to raise dust.

Waste Disposal Method:  In accordance with Local, State and Federal Waste Disposal Regulations.

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection: NIOSH approved respirator.

Ventilation:  Use local exhaust to maintain concentration at or below the PEL, TLV.  General exhaust is not recommended.

Eye Protection:  Safety glasses.

Protective Gloves:  Rubber gloves.

IX.   SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  Store in cool, dry area.  Store in tightly sealed container.  Wash thoroughly after handling.

Work Practices:  Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels.  Use good housekeeping and sanitation practices.  Do not use tobacco or food in work area.  Wash thoroughly before eating and smoking.  Do not blow dust off clothing or skin with compressed air.  Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
