3. HAZARDS IDENTIFICATION





EMERGENCY OVERVIEW

STRONG OXIDIZER.

MAY BE HARMFUL IF SWALLOWED.



Appearance:

Colorless crystals

POTENTIAL HEALTH EFFECTS (ACUTE AND CHRONIC)



Symptoms of Exposure:

May be harmful if swallowed. Ingestion of large quantity may cause kidney and liver damage.



Medical Cond. Aggravated by Exposure:

Data not available.



Routes of Entry:

Inhalation, ingestion





Carcinogenicity:

The material is not listed (IARC, NTP, OSHA) as cancer causing

agent.



4. FIRST AID MEASURES





Emergency First Aid:

GET MEDICAL ASSISTANCE FOR ALL CASES OF OVEREXPOSURE.

Skin: Wash thoroughly with soap and water.

Eyes: Immediately flush thoroughly with water for at least 15

minutes.

Inhalation: Remove to fresh air; give artificial respiration if

breathing has stopped.

Ingestion: If conscious, drink water and induce vomiting

immediately as directed by medical personnel. Never give anything

by mouth to an unconscious person.



5. FIRE FIGHTING MEASURES





Flash Point (F): Noncombustible

Flammable Limits LEL (%): N/A

Flammable Limits UEL (%): N/A

Extinguishing Media:

Use any suitable for adjacent material.



Fire Fighting Procedures:

Wear self-contained breathing apparatus.



Fire & Explosion Hazards:

Contact with other material may cause fire or explosion.



6. ACCIDENTAL RELEASE MEASURES





Spill Response:

Evacuate the area of all unnecessary personnel. Wear suitable protective equipment listed under Exposure / Personal

Protection. Eliminate any ignition sources until the area is determined to be free from explosion or fire hazards. Contain the

release and eliminate its source, if this can be done without risk. Take up and containerize for proper disposal as described

under Disposal. Comply with Federal, State, and local regulations on reporting releases. Refer to Regulatory Information for

reportable quantity and other regulatory data.



7. HANDLING AND STORAGE





Handling & Storage:

Keep container closed. Store in a cool, dry area away from reducing agents and combustible material. Do not breathe dust.

Do not get in eyes, on skin, or on clothing. Retained residue may make empty containers hazardous; use caution!



8. EXPOSURE CONTROLS / PERSONAL PROTECTION





ENGINEERING CONTROLS AND PERSONAL PROTECTIVE EQUIPMENT:

Ventilation, Respiratory Protection, Protective Clothing, Eye Protection:

Material should be handled or transferred in an approved fume hood or with adequate ventilation. Protective gloves

(Neoprene, PVC or equivalent) should be worn to prevent skin contact. Safety glasses with side shields should be worn at all

times.



Work/Hygenic Practices:

Wash thoroughly after handling. Do not take internally. Eye wash and safety equipment should be readily available.
