**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Flammable. Causes burns.Moisture sensitive.The toxicological
properties of this material have not been fully investigated.

Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns.
Ingestion:
Causes gastrointestinal tract burns. The toxicological properties of
this substance have not been fully investigated.
Inhalation:
Causes chemical burns to the respiratory tract. The toxicological
properties of this substance have not been fully investigated.
Chronic:
Chronic exposure may cause effects similar to those of acute
exposure.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device
such as a bag and a mask.
Notes to Physician:
Treat symptomatically and supportively.

**** 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. Vapors can travel to a source of ignition and flash
back. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion. Will burn if
involved in a fire. Flammable liquid and vapor. Runoff from fire
control or dilution water may cause pollution.
Extinguishing Media:
Use foam, dry chemical, or carbon dioxide.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

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. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Ground and bond containers when
transferring material. 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. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Keep container
tightly closed. Do not ingest or inhale. Use only in a chemical fume
hood. Discard contaminated shoes. Do not pressurize, cut, weld,
braze, solder, drill, grind, or expose empty containers to heat,
sparks or open flames. Keep away from heat, sparks and flame.
Storage:
Keep away from heat, sparks, and flame. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Refrigerator/flammables. Store protected
from moisture. Store under nitrogen.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local explosion-proof ventilation to keep airborne levels to
acceptable levels.
Exposure Limits
CAS# 25561-30-2:

exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
