**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful by inhalation and if swallowed. Very toxic to aquatic
organisms, may cause long-term adverse effects in the aquatic
environment.Possible risk of irreversible effects.Light
sensitive.Air sensitive.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. Prolonged and/or repeated contact may
cause irritation and/or dermatitis. May cause skin sensitization, an
allergic reaction, which becomes evident upon re-exposure to this
material.
Ingestion:
Harmful if swallowed. Causes gastrointestinal irritation with
nausea, vomiting and diarrhea. May cause methemoglobinemia, cyanosis
(bluish discoloration of skin due to deficient oxygenation of the
blood), convulsions, and death.
Inhalation:
Causes respiratory tract irritation. May cause asthmatic attacks due
to allergic sensitization of the respiratory tract. Methemoglobinemia
is characterized by dizziness, drowsiness, headache, shortness of
breath, cyanosis (bluish discoloration of skin due to deficient
oxygenation of the blood), rapid heart rate and chocolate-brown
blood. May cause methemoglobinemia.
Chronic:
Prolonged or repeated skin contact may cause dermatitis.
**** 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:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
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:
**** 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. 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:
In case of fire, use water, dry chemical, chemical foam, or
alcohol-resistant 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. 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. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Use with adequate
ventilation. Minimize dust generation and accumulation. Avoid
contact with eyes, skin, and clothing. Keep container tightly
closed. Do not ingest or inhale.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Store
protected from light.
**** 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.
Exposure Limits
CAS# 123-30-8:
Russia: 1 mg/m3 TWA

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.
