**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful by inhalation and if swallowed. Contact with combustible
material may cause fire. Explosive when mixed with combustible
material.
Potential Health Effects
Eye:
May cause conjunctivitis. May cause permanent corneal
opacification.
Skin:
Contact with skin causes irritation and possible burns, especially
if the skin is wet or moist. May cause severe irritation and possible
burns.
Ingestion:
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, shortness of breath, cyanosis (bluish discoloration of skin
due to deficient oxygenation of the blood), rapid heart rate and
chocolate-brown colored blood. May cause burns to the
gastrointestinal tract. May be harmful if swallowed. May cause
nausea, vomiting, and diarrhea, possibly with blood.
Inhalation:
Dust is irritating to the respiratory tract. May cause
methemoglobinemia, cyanosis (bluish discoloration of skin due to
deficient oxygenation of the blood), convulsions, tachycardia,
dyspnea (labored breathing), and death. May cause acute pulmonary
edema, asphyxia, chemical pneumonitis, and upper airway obstruction
caused by edema.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. May cause
liver and kidney damage. May cause methemoglobinemia, which is
characterized by chocolate-brown colored blood, headache, weakness,
dizziness, breath shortness, cyanosis (bluish skin due to deficient
oxygenation of blood), rapid heart rate, unconsciousness and
possible death.
**** 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 immediately. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
Ingestion:
Do not induce vomiting. 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:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
For methemoglobinemia, administer oxygen alone or with Methylene
Blue depending on the methemoglobin concentration in the blood.
Antidote:
Methylene blue, alone or in combination with oxygen is indicated as
a treatment in nitrite induced methemoglobinemia.
**** 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. Strong oxidizer. Contact with other material may
cause fire. Use water spray to keep fire-exposed containers cool.
Use water with caution and in flooding amounts. Some oxidizers may
react explosively with hydrocarbons(fuel). Containers may explode
when heated.
Extinguishing Media:
Contact professional fire-fighters immediately. For small fires, do
NOT use dry chemicals, carbon dioxide, halon or foams. USE WATER
ONLY. For large fires, flood fire area with water from a distance.
Contact with water or steam may produce toxic and flammable vapors.
**** 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.
Remove all sources of ignition. Do not use combustible materials such
as paper towels to clean up spill.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Keep container tightly closed. Keep away
from heat, sparks and flame. Avoid contact with clothing and other
combustible materials. Do not get on skin or in eyes. Avoid
ingestion and inhalation.
Storage:
Keep away from heat, sparks, and flame. Do not store near
combustible materials. Store in a cool, dry place. Keep away from
reducing agents.
**** 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# 3811-04-9:
