EMERGENCY OVERVIEW
Appearance: brown-black solid.
Danger! Strong oxidizer. Contact with other
material may cause a fire. Harmful if swallowed. Causes severe
respiratory tract irritation. May cause severe skin irritation and
possible burns. Contact with skin causes irritation and possible
burns, especially if the skin is wet or moist. May cause cyanosis
(bluish discoloration of skin due to deficient oxygenation of the
blood).
Target Organs: None.
Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns.
Skin:
May cause severe irritation and possible burns.
Ingestion:
Harmful if swallowed. May cause severe gastrointestinal tract
irritation with nausea, vomiting and possible burns.
Inhalation:
May cause irritation of the respiratory tract with burning pain in
the nose and throat, coughing, wheezing, shortness of breath and
pulmonary edema.
Chronic:
Chronic inhalation can cause pneumoconiosis.
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. Do NOT allow victim to rub eyes or keep eyes closed.
Skin:
Get medical aid immediately. 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:
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.
Antidote:
None.
Section 5 - Fire Fighting Measures
|
General Information:
Strong oxidizer. Contact with other material may cause fire. Wear
appropriate protective clothing to prevent contact with skin and
eyes. Wear a self-contained breathing apparatus (SCBA) to prevent
contact with thermal decomposition products.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam.
Flash Point: Not applicable.
Autoignition Temperature: Not applicable.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 2; Flammability: 0; Instability: 1; Special Hazard: OX
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. Remove all sources of
ignition.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Use with adequate ventilation. Keep
container tightly closed. Avoid contact with clothing and other
combustible materials. Do not get on skin or in eyes. Do not ingest
or inhale. Do not store near combustible materials.
Storage:
Keep away from sources of ignition. Do not store near combustible
materials. Store in a tightly closed container. Store in a cool,
dry, well-ventilated area away from incompatible substances.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
