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

EMERGENCY OVERVIEW
Harmful if swallowed. Irritating to eyes, respiratory system and
skin. Very toxic to aquatic organisms; may cause long-term adverse
effects in the aquatic environment.Light sensitive.

Potential Health Effects
Eye:
Contact produces irritation, tearing, and burning pain. Vapors
cause eye irritation.
Skin:
Causes irritation with burning pain, itching, and redness.
Ingestion:
Harmful if swallowed. May cause central nervous system depression,
kidney damage, and liver damage.
Inhalation:
May cause respiratory tract irritation. May cause liver and kidney
damage. May cause drowsiness, unconsciousness, and central nervous
system depression.
Chronic:
Prolonged or repeated exposure may cause adverse reproductive
effects. May cause liver and kidney damage. May cause fetal effects.

**** 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:
Get medical aid. Immediately flush skin with plenty of soap and
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse.
Ingestion:
Do NOT induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure to fresh air
immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
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 may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. Combustion
generates toxic fumes. Use water spray to keep fire-exposed
containers cool. Vapors may be heavier than air. They can spread
along the ground and collect in low or confined areas. Containers may
explode when heated.
Extinguishing Media:
Use water fog, dry chemical, carbon dioxide, or regular foam. Use
agent most appropriate to extinguish fire. Cool containers with
flooding quantities of water until well after fire is out.

**** 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. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation.

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

Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Ground and bond containers when transferring material. Avoid contact
with eyes, skin, and clothing. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Avoid
ingestion and inhalation. Do not pressurize, cut, weld, braze,
solder, drill, grind, or expose empty containers to heat, sparks or
open flames.
Storage:
Keep away from sources of ignition. 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:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
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 protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29CFR
1910.134 or European Standard EN 149. Always use a
NIOSH or European Standard EN 149 approved respirator
when necessary.
