EMERGENCY OVERVIEW
Appearance: white crystals.
Danger! Oxidizer. Harmful if swallowed. Causes eye
and skin irritation. Causes digestive and respiratory tract
irritation. May cause cancer based on animal studies. May cause
central nervous system depression. May cause liver and kidney damage.
Target Organs: Kidneys, central nervous system,
liver.
Potential Health Effects
Eye:
Causes moderate eye irritation. May cause transient corneal
injury.
Skin:
May cause skin irritation. In the presence of moisture, this
material may be absorbed through the skin.
Ingestion:
Harmful if swallowed. Causes gastrointestinal irritation with
nausea, vomiting and diarrhea. May cause liver and kidney damage.
May cause central nervous system depression. Hearing loss and
deafness have been reported.

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. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
Ingestion:
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
Administration of Sodium bicarbonate may be of value to treat
acidosis.

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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Oxidizer.
Greatly increases the burning rate of combustible materials. Some
oxidizers may react explosively with hydrocarbons(fuel). Containers
may explode if exposed to fire.
Extinguishing Media:
Use flooding quantities of water as spray. Cool containers with
flooding quantities of water until well after fire is out. For small
fires, do NOT use dry chemicals, carbon dioxide, halon or foams. USE
WATER ONLY.
Flash Point: Not available.
Autoignition Temperature: Not available.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 2; Flammability: 0; Instability: 2; Special Hazard: OX
|
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Wash area with soap and water. Clean up spills immediately,
observing precautions in the Protective Equipment section. Sweep up,
then place into a suitable container for disposal. Do not use
combustible materials such as paper towels to clean up spill.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Avoid contact with
skin and eyes. Keep container tightly closed. Do not ingest or
inhale.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Keep containers tightly closed.
|
Section 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 process enclosure,
local exhaust ventilation, or other engineering controls to control
airborne levels.
