**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if swallowed. Danger
of cumulative effects. Very toxic to aquatic organisms, may cause
long-term adverse effects in the aquatic environment.Light sensitive.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Ingestion:
May cause irritation of the digestive tract. May cause effects
similar to those of acute inhalation.
Inhalation:
Inhalation of vapor may cause respiratory tract irritation. May
cause methemoglobinemia, cyanosis (bluish discoloration of skin due
to deficient oxygenation of the blood), convulsions, tachycardia,
dyspnea (labored breathing), and death. May cause adverse central
nervous system effects including headache, convulsions, and possible
death. May cause bladder injury and hypertension.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. May cause
reproductive and fetal effects. There is a danger of cumulative
effects.
**** 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.
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. Destroy contaminated shoes.
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:
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:
Absorption of this product into the body may cause cyanosis (bluish
discoloration of skin due to deficient oxygenation of the blood).
Moderate degrees of cyanosis need to be treated only by supportive
measures: bed rest and oxygen inhalation. For methemoglobinemia,
administer oxygen alone or with Methylene Blue depending on the
methemoglobin concentration in the blood. Cleansing of the entire
contaminated area of the body is of utmost importance.
**** 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. This material in sufficient quantity and reduced
particle size is capable of creating a dust explosion.
Extinguishing Media:
Water or foam may cause frothing. In case of fire, use carbon
dioxide, dry chemical powder 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. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Remove contaminated clothing and wash before reuse. Use with
adequate ventilation. Avoid contact with eyes, skin, and clothing. Do
not ingest or inhale. Store protected from light.
Storage:
Keep away from sources of ignition. Do not store in direct sunlight.
Store in a tightly closed container. Keep from contact with oxidizing
materials. Store in a cool, dry, well-ventilated area away from
incompatible substances. Store protected from light.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
