Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Very toxic by inhalation. Irritating to respiratory system.Corrosive.Toxic.
Potential Health Effects
Eye:
May cause eye burns.
Skin:
May cause skin irritation and possible burns.
Ingestion:
Low hazard for usual industrial handling.
Inhalation:
May be fatal if inhaled. Causes respiratory tract irritation. May cause burns to the respiratory tract. Symptoms of initial exposure may include nocturnal dyspnea (labored breathing) with nocturnal cough with progression to asthmatic bronchitis. Has poor warning properties at low concentrations. Condition may then enter a second stage of abruptly increasing severity; fever and chills precede a relapse, with increasing dyspnea (labored breathing), cyanosis (bluish skin due to deficient oxygenation of the blood), and recurring pulmonary edema. Death may occur in either the initial or the second stage of the illness; a severe second stage may follow a relatively mild initial stage.
Chronic:
Chronic inhalation may cause effects similar to those of acute inhalation.

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:
Get medical aid if irritation or symptoms occur.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
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. Strong oxidizer. Contact with other material may cause fire. Containers may explode when heated. Vapors from liquefied gas are initially heavier than air and spread along ground. Reacts with water to form corrosive acids.
Extinguishing Media:
Substance is nonflammable; use agent most appropriate to extinguish surrounding fire. Do not direct water at source of leak or safety devices; icing may occur.

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Remove all sources of ignition. Isolate area and deny entry. Provide ventilation. Prevent spreading of vapors through sewers, ventilation systems and confined areas. Stop leak only if you can do so without risk. Use water spray to reduce vapors or divert vapor cloud drift.

Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Keep away from heat, sparks and flame. Do not ingest or inhale.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
