SECTION 3: Hazards Identification
Emergency Overview:	Extremely destructive to the upper respiratory tract, eyes and skin. Material hydrolyzes in contact with moisture releasing corrosive hydrogen chloride fumes.
Primary Routes of Exposure:	Ingestion, inhalation, skin, eyes
Eye Contact:	Liquid and vapors cause burns to the eyes and blindness.
Skin Contact:	Corrosive to skin. Contact can lead to redness, pain, blistering, ulceration, and scar formation.
Inhalation:	Inhalation of choking fumes will result in burning of the respiratory tract, chemical pneumonitis and pulmonary edema.
Ingestion:	Ingestion is unlikely due to pungent choking odor. Causes burns to the gastrointestinal system.
Acute Health Effects:	May be harmful if swallowed, inhaled or absorbed through the skin. Material is extremely destructive to tissue of the mucous membranes, upper respiratory tract, skin and eyes.
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 away from moisture. If possible, handle material in an efficient fume hood. Prolonged exposure to the atmosphere may 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 clothing and gloves. Consult with glove manufacturer to determine the proper type of glove.
Ventilation:	If possible, handle the material in an efficient fume hood.
Respirator:	In the absence of adequate ventilation a respirator should be worn. The use of a respiratory requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134.
Additional Protection:	No additional protection required.
