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.

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.

Skin: Wear impervious gloves. 
Clothing: Wear appropriate protective clothing to prevent skin 
exposure. 
Respirators: Follow the OSHA respirator regulations found in 29 CFR 
1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 
149 approved respirator if exposure limits are exceeded or if irritation or 
other symptoms are experienced.
