Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Very toxic by inhalation. Causes burns.Moisture sensitive.Corrosive.
Potential Health Effects
Eye:
Causes severe eye burns.
Skin:
Causes severe skin irritation and burns.
Ingestion:
May cause irritation of the digestive tract.
Inhalation:
May be fatal if inhaled. Causes severe respiratory tract irritation.
Exposure may cause heavy tearing, coughing, nausea, and dyspnea (labored breathing). Exposure may produce dryness or a burning sensation of the throat; vomiting; cough; foamy sputum; dyspnea (labored breathing); pain in the chest and cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood).
Exposure may produce pulmonary edema which may progress to pneumonia, and cardiac failure may intervene. Death may occur due to asphyxiation or heart failure. Has poor warning properties at low concentrations.
Chronic:
No information found.

Section 4 - FIRST AID MEASURES
Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
Skin:
Get medical aid immediately. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation:
Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. SPEED IS ESSENTIAL, OBTAIN MEDICAL AID IMMEDIATELY.
Notes to Physician:

Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Containers may explode when heated. Vapors from liquefied gas are initially heavier than air and spread along ground.
Reacts with most metals in the presence of moisture, liberating extremely flammable hydrogen gas.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use water spray, dry chemical, carbon dioxide, or alcohol-resistant foam.

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective Equipment section. Isolate area and deny entry. Provide ventilation.
Prevent spreading of vapors through sewers, ventilation systems and confined areas. Use water spray to reduce vapors or divert vapor cloud drift.

Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale. Use only in a chemical fume hood.
Storage:
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Store below 50C. Outside or detached storage is preferred.
