**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Contact with water liberates extremely flammable
gases.Water-reactive.Corrosive.
Potential Health Effects
Eye:
Causes eye irritation and possible burns.
Skin:
Contact with skin causes irritation and possible burns, especially
if the skin is wet or moist.
Ingestion:
Causes digestive tract irritation with possible burns.
Inhalation:
May cause systemic effects. Causes severe respiratory tract
irritation with possible burns.
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:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists. Wash clothing before reuse.
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.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid if cough or other symptoms appear.
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. Will react with water to form toxic and corrosive
fumes. Reacts with water to form explosive hydrogen gas. May ignite
on contact with water or moist air.
Extinguishing Media:
Use dry sand or earth to smother fire. Do NOT get water inside
containers. DO NOT USE WATER OR FOAM. For small fires, use dry
chemical, soda ash, lime or sand. For large fires, use dry sand, dry
chemical, soda ash or lime or withdraw from area and let fire burn.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Use water spray to disperse the gas/vapor. Remove all
sources of ignition. Provide ventilation. Do not expose spill to
water.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation. Avoid
breathing dust, vapor, mist, or gas. Avoid contact with skin and
eyes. Avoid ingestion and inhalation.
Storage:
Store in a cool, dry place. Store in a tightly closed container.
Keep away from water. Corrosives area. Store totally immersed in oil.
**** 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 process enclosure,
local exhaust ventilation, or other engineering controls to control
airborne levels.

Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
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.
