**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Causes burns. Toxic in contact with skin and if
swallowed.Corrosive.Toxic.

Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns. May cause conjunctivitis and keratitis.
Skin:
May be absorbed through the skin in harmful amounts. May cause skin
sensitization, an allergic reaction, which becomes evident upon
re-exposure to this material. Causes severe skin irritation and
burns.
Ingestion:
Causes gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause liver and kidney damage. Causes severe digestive
tract burns with abdominal pain, vomiting, and possible death. May
cause hemorrhaging of the digestive tract.
Inhalation:
Causes respiratory tract irritation. May cause breathing difficulty,
headache, nausea, muscle weakness, and possible respiratory tract
abnormalities.
Chronic:
May cause liver and kidney damage. May cause appetite loss,
diarrhea, skin abnormalities, and digestive tract disturbances.

**** 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
immediately.
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.
Get medical aid immediately.

breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:

**** 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. Vapors can travel to a source of ignition and flash
back.
Extinguishing Media:
Use water spray, dry chemical, or foam.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Wear a self contained breathing apparatus and appropriate personal
protection. (See Exposure Controls, Personal Protection section).
Sweep up, then place into a suitable container for disposal. Avoid
generating dusty conditions.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Empty containers retain product residue,
(liquid and/or vapor), and can be dangerous. Keep container tightly
closed. Do not get on skin or in eyes. Do not ingest or inhale. Do
not pressurize, cut, weld, braze, solder, drill, grind, or expose
empty containers to heat, sparks or open flames.
Storage:
Keep from contact with oxidizing materials. Store in a cool, dry,
well-ventilated area away from incompatible substances.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Personal Protective Equipment

Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate gloves to prevent skin exposure.
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. Always use
a NIOSH or European Standard EN 149 approved
respirator when necessary.
