Section 3 - Hazards Identification

EMERGENCY OVERVIEW
Appearance: brown powder.
Danger! May be fatal if swallowed. Methemoglobin
formation is the prinicipal cause of toxicity.
Target Organs: Blood, liver.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. May be fatal if absorbed through the
skin.
Ingestion:
May be fatal if swallowed. May cause irritation of the digestive
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 colored blood. Effects may be delayed. May form
methemoglobin which in sufficient concentration causes cyanosis
(bluish discoloration of skin due to deficient oxygenation of the
blood).
Inhalation:
May be fatal if inhaled. May cause respiratory tract irritation.
Chronic:
There is a danger of cumulative effects. May cause adverse
reproductive effects.
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 imme
diately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes.
Ingestion:
POISON material. If swallowed, get medical aid immediately. Only
induce vomiting if directed to do so by medical personnel. Never give
anything by mouth to an unconscious person.
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.
Notes to Physician:
Treat symptomatically and supportively.
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. Dusts at sufficient concentrations can form
explosive mixtures with air.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical 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. Avoid generating dusty conditions.
Section 7 - Handling and Storage
|
Handling:
Do not breathe dust, mist, or vapor. Do not get in eyes, on skin, or
on clothing. Use only in a chemical fume hood.
Storage:
Store in a cool, dry place. Store in a tightly closed container.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
