Section 3 - Hazards Identification
Appearance: white solid. Danger! Strong oxidizer. Contact with
other material may cause a fire. May cause cyanosis (bluish discoloration
of skin due to deficient oxygenation of the blood). May cause
blood abnormalities. May be harmful if swallowed. May cause kidney
damage. May cause severe eye, skin and respiratory tract irritation
with possible burns.
Target Organs: Blood, kidneys.
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.
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
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
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.
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 combustible
materials may cause a 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.

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.
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.
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.
