SECTION 3: Hazards Identification
Emergency Overview:	Toxic by inhalation and if swallowed. The liquid is irritating to skin, eyes, and respiratory system. Danger of cumulative effects.
Primary Routes of Exposure:	Inhalation, ingestion, contact with skin and eyes.
Eye Contact:	The liquid and ethanol hydrolysis product will cause moderate irritation of the eyes.
Skin Contact:	Dehydrating agent. Liquid will cause mild irritation of the skin.
Inhalation:	Toxic by inhalation. Thallium poisoning may occur. Ethanol vapor may cause dizziness and drowsiness.
Ingestion:	Toxic if swallowed. Ingestion may result in swelling of the feet and legs, mental confusion, paralysis, angina-like pains.
Acute Health Effects:	Toxic by inhalation and if swallowed. Acute poisoning results in pain of the extremities, fever, difficulty in moving, nausea and vomiting. Irritating to skin, eyes and respiratory tract.
Chronic Health Effects:	Danger of cumulative effects. Prolonged exposure to thallium compounds has been reported to lead to discoloration of the hair, which later falls out, joint pain, loss of appetite, fatigue, severe pain in the legs, albuminuria, and optic neuritis. Possible mutagen.
NTP:	No
IARC:	No
OSHA:	No

SECTION 4: First Aid Measures
Eye Exposure:	Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure:	Wash the affected area with soap and water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
Inhalation:	Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
Ingestion:	Seek medical attention immediately for possible antidote and treatment. Keep the victim calm. Give the victim water (only if conscious).

SECTION 5: Fire Fighting Measures
Flash Point:	not applicable
Autoignition Temperature:	no data
Explosion Limits:	no data
Extinguishing Medium:	carbon dioxide, dry powder or foam
Special Fire Fighting Procedures:	If involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing.
Hazardous Combustion and Decomposion Products:	If involved in a fire this material may emit toxic organic fumes and toxic thallium oxide dust.
Unusual Fire or Explosion Hazards:	No unusual fire or explosion hazards.

SECTION 6: Accidental Release Measures
Spill and Leak Procedures:	Eliminate all ignition sources. Avoid contact with water. Small spills may be adsorbed into diatomaceous earth, sand, or other suitable adsorbent, and swept up.

SECTION 7: Handling and Storage
Handling and Storage:	Store in a tightly sealed container in a cool dry place. If container is left open, product may adsorb moisture from the atmosphere and release ethanol vapor.

SECTION 8: Exposure Controls and Personal Protection
Eye Protection:	Always wear approved safety glasses when handling a chemical substance in the laboratory.
Skin Protection:	Wear protective clothing and gloves.
Ventilation:	Material may form a vapor upon exposure to air. if possible, handle the material in an efficient fume hood.
Respirator:	If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134.
Additional Protection:	No additional protection required.
