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

EMERGENCY OVERVIEW
Harmful in contact with skin. Limited evidence of a carcinogenic
effect. Risk of serious damage to eyes. May cause sensitization by
skin contact.

Potential Health Effects
Eye:
Causes severe eye irritation.
Skin:
Harmful if absorbed through the skin. May cause skin sensitization,
an allergic reaction, which becomes evident upon re-exposure to this
material.
Ingestion:
Methemoglobinemia is characterized by dizziness, drowsiness,
headache, shortness of breath, cyanosis (bluish discoloration of skin
due to deficient oxygenation of the blood), rapid heart rate and
chocolate-brown colored blood. May be harmful if swallowed.
Overexposure may cause methemoglobinemia.
Inhalation:
Not available.
Chronic:
Chronic exposure may cause liver damage.

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

Eyes:
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. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Remove
contaminated clothing and shoes.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move 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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Flammable
liquid and vapor. Vapors are heavier than air and may travel to a
source of ignition and flash back. Vapors can spread along the ground
and collect in low or confined areas.
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. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Provide ventilation.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Avoid contact with eyes, skin, and clothing. Avoid
ingestion and inhalation. Use only with adequate ventilation. Keep
away from heat, sparks and flame.
Storage:
Keep away from sources of ignition. Keep container closed when not
in use. 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 process enclosure,
local exhaust ventilation, or other engineering controls to control
airborne levels.
Exposure Limits
CAS# 96-29-7:


Personal Protective Equipment

Eyes:
Wear chemical splash goggles.
Skin:

Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use.
