EMERGENCY OVERVIEW
Very toxic by inhalation. Causes burns. May cause cancer. Toxic in contact with skin and if swallowed. Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.
Potential Health Effects
Eye:
Causes eye burns. Lachrymator (substance which increases the flow of tears).
Skin:
Causes skin burns. Toxic in contact with skin.
Ingestion:
Poison by ingestion. Causes gastrointestinal tract burns.
Inhalation:
May be fatal if inhaled. Causes chemical burns to the respiratory tract. May cause abdominal pain, nausea, vomiting, and inflammation of the gums and mouth.
Chronic:
May cause cancer in humans.

Eyes: Immediately 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. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. SPEED IS ESSENTIAL. A DOCTOR MUST BE NOTIFIED AT ONCE.
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:

General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Will burn if involved in a fire.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam.

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Remove all sources of ignition.
Use a spark-proof tool.

Handling:
Use spark-proof tools and explosion proof equipment. Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Use only in a chemical fume hood.
Storage:
Keep away from sources of ignition. Store in a tightly closed container. Store in a dry area. Keep under an argon blanket. Keep refrigerated. (Store below 4C/39F.)

Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
