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

EMERGENCY OVERVIEW
Harmful if swallowed. Toxic by inhalation. Causes burns. Toxic to
aquatic organisms, may cause long-term adverse effects in the
aquatic environment.

Potential Health Effects
Eye:
Causes eye burns. May cause chemical conjunctivitis and corneal
damage.
Skin:
Harmful if absorbed through the skin. Causes skin burns.
Ingestion:
Harmful if swallowed. Causes gastrointestinal tract burns.
Inhalation:
Harmful if inhaled. Causes chemical burns to the respiratory tract.
Chronic:
May cause liver and kidney damage. May cause methemoglobinemia,
which is characterized by chocolate-brown colored blood, headache,
weakness, dizziness, breath shortness, cyanosis (bluish skin due to
deficient oxygenation of blood), rapid heart rate, unconsciousness
and possible death. Effects may be delayed.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.

**** 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. Contact
with metals may evolve flammable hydrogen gas. Combustible material;
may burn but does not ignite readily. Runoff from fire control or
dilution water may cause pollution.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.

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

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Provide
ventilation.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not get in eyes, on skin, or on clothing. Keep
container tightly closed. Discard contaminated shoes. Use only with
adequate ventilation. Do not breathe vapor or mist.
Storage:
Store in a cool, dry place. Keep container closed when not in use.
Corrosives area.

**** 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 adequate
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 88-18-6:


Personal Protective Equipment

Eyes:
Wear chemical splash goggles.
