**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation and if swallowed. Danger of cumulative
effects.Moisture sensitive.
Potential Health Effects
Eye:
May cause severe eye irritation. May cause eye irritation.
Skin:
May cause skin irritation. Causes skin irritation. Prolonged and/or
repeated contact may cause irritation and/or dermatitis.
Ingestion:
Ingestion of large amounts may cause gastrointestinal irritation.
Low hazard for usual industrial handling. May cause digestive tract
disturbances.
Inhalation:
Causes respiratory tract irritation. May cause respiratory tract
irritation. Low hazard for usual industrial handling.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. 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. Immediately flush
eyes with plenty of water for at least 15 minutes, occasionally
lifting the upper and lower eyelids. Get medical aid immediately. If
irritation develops, get medical aid.
Skin:
Get medical aid immediately. 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:
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. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water. Get medical aid
if irritation or symptoms occur.
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. Get
medical aid.
Notes to Physician:
Antidote:
None reported.
**** 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 may form an explosive mixture with air.
During a fire, irritating and highly toxic gases may be generated by
thermal decomposition or combustion. This material in sufficient
quantity and reduced particle size is capable of creating a dust
explosion.
Extinguishing Media:
Substance is nonflammable; use agent most appropriate to extinguish
surrounding fire. Use water spray, dry chemical, carbon dioxide, or
chemical foam. Do NOT get water inside containers. Use water spray,
dry chemical, carbon dioxide, or appropriate foam.
**** 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. Avoid runoff into storm sewers and ditches which lead to
waterways. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation. Do not get water inside containers.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Minimize dust generation
and accumulation. Avoid breathing dust, vapor, mist, or gas. Avoid
contact with eyes, skin, and clothing. Keep container tightly
closed. Avoid ingestion and inhalation. Use with adequate
ventilation. Do not allow contact with water. Use only in a chemical
fume hood. Keep from contact with moist air and steam.
Storage:
Store in a tightly closed container. Keep from contact with
oxidizing materials. Store in a cool, dry, well-ventilated area away
from incompatible substances. Do not store in aluminum containers.
Store protected from moisture.
**** 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
ventilation to keep airborne concentrations low.

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:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use. 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.
