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

EMERGENCY OVERVIEW
Harmful by inhalation and if swallowed. Danger of cumulative
effects. May cause harm to the unborn child. Possible risk of
impaired fertility. Very toxic to aquatic organisms, may cause
long-term adverse effects in the aquatic environment.Oxidizer.

Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause kidney damage.
Inhalation:
Causes respiratory tract irritation. May cause effects similar to
those described for ingestion.
Chronic:
Chronic exposure to lead may result in plumbism which is
characterized by lead line in gum, headache, muscle weakness, mental
changes.

**** 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.
Skin:
Immediately flush skin with plenty of water for at least 15 minutes
while removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Get medical aid immediately.
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:
Antidote:
The use of Dimercaprol or BAL (British Anti-Lewisite) as a chelating
agent should be determined by qualified medical personnel. The use of
Calcium disodium EDTA as a chelating agent should be determined by
qualified medical personnel. The use of d-Penicillamine as a
chelating agent should be determined by qualified medical personnel.

**** 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. Combustion generates toxic fumes. Oxidizer. Greatly
increases the burning rate of combustible materials.
Extinguishing Media:
Use water only!

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

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
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. Avoid contact with eyes, skin, and
clothing. Empty containers retain product residue, (liquid and/or
vapor), and can be dangerous. Keep container tightly closed. Avoid
ingestion and inhalation. Keep from contact with clothing and other
combustible materials. Do not pressurize, cut, weld, braze, solder,
drill, grind, or expose empty containers to heat, sparks or open
flames.
Storage:
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 ventilation to keep airborne concentrations low.
