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

EMERGENCY OVERVIEW
Very toxic by inhalation, in contact with skin and if swallowed.
Danger of cumulative effects. Very toxic to aquatic organisms.

Potential Health Effects
Eye:
Causes severe eye irritation.
Skin:
May be absorbed through the skin in harmful amounts. May cause skin
sensitization, an allergic reaction, which becomes evident upon
re-exposure to this material. If absorbed, may cause symptoms
similar to those for ingestion. Effects of contact may be delayed.
May cause contact dermatitis.
Ingestion:
May cause irritation of the digestive tract. May cause kidney
damage. May cause methemoglobinemia, cyanosis (bluish discoloration
of skin due to deficient oxygenation of the blood), convulsions, and
death. Methemoglobinemia is characterized by dizziness, drowsiness,
headache, breath shortness, cyanosis with bluish skin, rapid heart
rate and chocolate-brown colored blood. May be harmful if swallowed.
Inhalation:
May cause severe allergic respiratory reaction. May cause
respiratory tract irritation. Effects of inhalation may be delayed.
Chronic:
May cause cancer according to animal studies.

**** 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
immediately.
Skin:
Flush skin with plenty of soap and water for at least 15 minutes
while removing contaminated clothing and shoes. Wash clothing before
reuse. Get medical aid if symptoms occur.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
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 to fresh air
immediately. If breathing is difficult, give oxygen. If breathing has
ceased apply artificial respiration using oxygen and a suitable
mechanical device such as a bag and a mask.
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. May polymerize explosively when involved in a fire.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or
alcohol-resistant foam. Do NOT get water inside containers. 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:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable 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.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Minimize dust
generation and accumulation. Do not get in eyes, on skin, or on
clothing. Do not ingest or inhale.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.

**** 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 exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
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 and clothing to
prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
Respirators:
Wear a NIOSH/MSHA or European Standard EN 149
approved full-facepiece airline respirator in the
positive pressure mode with emergency escape
provisions. Follow the OSHA respirator regulations
found in 29CFR 1910.134 or European Standard EN 149.
Always use a NIOSH or European Standard EN 149
approved respirator when necessary.
