SECTION 3: Hazards Identification
Emergency Overview:	Causes burns to skin and eyes. Material hydrolyzes in contact with moisture releasing toxic and corrosive fumes of hydrogen chloride.
Primary Routes of Exposure:	Ingestion, inhalation, skin, eyes
Eye Contact:	Causes burns to the eyes.
Skin Contact:	Causes caustic burns to the skin.
Inhalation:	Forms hydrogen chloride in the presence of moisture. Inhalation can lead to burns of the respiratory tract.
Ingestion:	No information is available on the physiological effects of ingestion.
Acute Health Effects:	Corrosive to skin, eyes, mucous membranes and respiratory tract.
Chronic Health Effects:	No information available on long-term chronic effects.
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 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. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel.

SECTION 5: Fire Fighting Measures
Flash Point:	not applicable
Autoignition Temperature:	none
Explosion Limits:	none
Extinguishing Medium:	none required
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 chlorine and hydrochloric acid fumes.
Unusual Fire or Explosion Hazards:	No unusual fire or explosion hazards.

SECTION 6: Accidental Release Measures
Spill and Leak Procedures:	Small spills can be neutralized with powdered sodium bicarbonate, lime, or calcium carbonate and swept up. Large spills in areas not adequately ventilated will require an evacuation of site. Emergency response teams will require self-contained breathing apparatus.

SECTION 7: Handling and Storage
Handling and Storage:	Store material in a tightly sealed bottle, preferably under an inert atmosphere. Handle material in an efficient fume hood. Prolonged exposure to the atmosphere will lead to degradation of the product.

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 gloves and clothing when handling this product.
Ventilation:	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.
