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

EMERGENCY OVERVIEW
Highly flammable.

Potential Health Effects
Eye:
May cause lacrimation (tearing), blurred vision, and photophobia.
May cause chemical conjunctivitis and corneal damage.
Skin:
May cause skin irritation and possible burns.
Ingestion:
May cause anemia, leukopenia (reduction in the number of white blood
cells in the blood), and thrombocytopenia. May cause headache, fever,
nausea, abdominal pain, muscle pain and bloody urine.
Inhalation:
Olfactory fatigue may occur. When inhaled as a dust or fume, may
cause benign pneumoconiosis. Can produce delayed pulmonary edema.
Chronic:
No information found.

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

Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse.
Ingestion:
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.
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 victim ingested or inhaled the
substance; induce artificial respiration with the aid of a pocket
mask equipped with a one-way valve or other proper respiratory
medical device.
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. Dust can be an explosion hazard when exposed to
heat or flame. Flammable solid. May burn rapidly with flare burning
effect. May re-ignite after fire is extinguished. Runoff to sewer may
create fire or explosion hazard.
Extinguishing Media:
Do NOT use water directly on fire. For large fires, use water spray,
fog or regular foam. Contact professional fire-fighters immediately.
For small fires, use dry chemical, carbon dioxide, sand, earth,
water spray or regular 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, then place into a suitable container for disposal. Scoop
up with a nonsparking tool, then place into a suitable container for
disposal. Avoid generating dusty conditions. Remove all sources of
ignition.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. Avoid
contact with eyes, skin, and clothing. Empty containers retain
product residue, (liquid and/or vapor), and can be dangerous. Keep
away from heat, sparks and flame. Avoid ingestion and inhalation. Do
not pressurize, cut, weld, braze, solder, drill, grind, or expose
empty containers to heat, sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition.

**** 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# 7439-98-7:
United States OSHA: 15 mg/m3 TWA (total dust)
Malaysia: 10 mg/m3 TWA
Netherlands: 5 mg/m3 MAC
Russia: 3 mg/m3 TWA
Russia: 0.5 mg/m3 STEL

Personal Protective Equipment

Eyes:
Wear safety glasses and chemical goggles if splashing
is possible. 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.
