Section 3 - Hazards Identification |
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.
