**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation and if swallowed. Irritating to eyes,
respiratory system and skin. Very toxic to aquatic organisms.
Potential Health Effects
Eye:
Contact may cause discoloration, redness, swelling, and formation
of eye lesions.
Skin:
Causes skin irritation. Depigmentation and skin lesions may occur.
May cause discoloration, erythema (redness), swelling, and the
formation of papules and vesicles (blisters). Prolonged contact may
lead to necrosis.
Ingestion:
May be fatal if swallowed.
Inhalation:
Harmful if inhaled. Causes respiratory tract irritation. May cause
adverse central nervous system effects including headache,
convulsions, and possible death. May produce asphyxia due to
pulmonary damage and effects on the hemoglobin. May produce clonic
convulsions, respiratory difficulties, decreased blood pressure and
death due to medullary centers.
Chronic:
Prolonged or repeated exposure may cause permanent eye damage.
Prolonged or repeated contact may cause skin necrosis and/or
ulceration of the skin.
**** 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. Do NOT allow victim to rub eyes or keep eyes closed.
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:
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:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
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. Use water spray to keep fire-exposed containers
cool. This material in sufficient quantity and reduced particle size
is capable of creating a dust explosion. Violently decomposes when
heated under confinement. Water-wet material can decompose violently
above 50-70C (122-158F).
Extinguishing Media:
Use water spray or dry chemical.
**** 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. Avoid
generating dusty conditions. Remove all sources of ignition. Provide
ventilation. Use only non-sparking tools and equipment. Prevent
runoff from entering drains, sewers, or streams.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Minimize dust generation and accumulation. Keep
container tightly closed. Use only with adequate ventilation. Avoid
breathing dust. Avoid breathing vapor. Keep away from heat and
flame. Do not get in eyes. Avoid contact with skin and clothing.
Exercise caution in heating, especially in a closed container.
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.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.

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.
