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

EMERGENCY OVERVIEW
Irritating to eyes, respiratory system and
skin.Corrosive.Water-reactive.

Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns.
Skin:
May cause skin sensitization, an allergic reaction, which becomes
evident upon re-exposure to this material. May cause severe
irritation and possible burns.
Ingestion:
May cause irritation of the digestive tract and possible burns.
Inhalation:
May cause asthmatic attacks due to allergic sensitization of the
respiratory tract. May cause severe irritation of the respiratory
tract with possible burns.
Chronic:
Not available.

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

Eyes:
Get medical aid immediately. Gently lift eyelids and flush
continuously with water. Extensive irrigation with water is required
(at least 30 minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Do not induce vomiting. 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:
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. Do NOT use mouth-to-mouth
resuscitation.
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. Vapors can travel to a source of ignition and flash
back. Dust can be an explosion hazard when exposed to heat or flame.
Reacts with water to form explosive hydrogen gas. Vapors may be
heavier than air. They can spread along the ground and collect in
low or confined areas. Containers may explode when heated or if
contaminated with water.
Extinguishing Media:
Do NOT get water inside containers. For large fires, use water
spray, fog or alcohol-resistant foam. Do NOT use straight streams of
water. For small fires, use carbon dioxide, dry chemical, dry sand,
or alcohol-resistant foam. Cool containers with flooding quantities
of water until well after fire is out.

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

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Sweep up or absorb material, then place into a suitable clean, dry,
closed container for disposal. Avoid generating dusty conditions.
Remove all sources of ignition. Use a spark-proof tool. Do not get
water inside containers.

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

Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Ground and bond containers when transferring material. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep container tightly closed. Do not ingest or inhale. Do
not allow contact with water. Do not pressurize, cut, weld, braze,
solder, drill, grind, or expose empty containers to heat, sparks or
open flames.
Storage:
Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away
from water. Corrosives area.

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

Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
