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

EMERGENCY OVERVIEW
Flammable. Harmful in contact with skin and if swallowed. Toxic by
inhalation. Very toxic to aquatic organisms.Lachrymator (substance
which increases the flow of tears).

Potential Health Effects
Eye:
Causes severe eye irritation. Lachrymator (substance which
increases the flow of tears).
Skin:
Causes severe skin irritation. Harmful if absorbed through the skin.
Ingestion:
Harmful if swallowed. May cause severe digestive tract irritation
with abdominal pain, nausea, vomiting and diarrhea.
Inhalation:
May be fatal if inhaled. May cause severe irritation of the
respiratory tract with sore throat, coughing, shortness of breath
and delayed lung edema.
Chronic:
Prolonged or repeated skin contact may cause dermatitis.

**** 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.
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. Vapors can travel to a source of ignition and flash
back. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion. Containers may
explode in the heat of a fire.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use foam, dry
chemical, or carbon dioxide. DO NOT USE WATER!

**** 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. Wash area with soap and water.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Remove all sources of ignition. Provide
ventilation. Approach spill from upwind.

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

Handling:
Wash thoroughly after handling. Ground and bond containers when
transferring material. Use spark-proof tools and explosion proof
equipment. Avoid contact with eyes, skin, and clothing. Use only in a
chemical fume hood. Do not breathe vapor. Use only with adequate
ventilation. Keep away from heat, sparks and flame. Do not breathe
spray or mist.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container. Refrigerator/flammables. Store protected from light.

**** 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 only under a
chemical fume hood.
Exposure Limits

Malaysia: 5 mg/m3 TWA
Netherlands: 5 mg/m3 MAC
Spain: 5 mg/m3 VLA-ED

Personal Protective Equipment

Eyes:
Wear chemical splash goggles.
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 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.

**** SECTION 10 - STABILITY AND REACTIVITY ****

Chemical Stability:
Stable only if stored and handled under recommended conditions. The
stability of the product depends upon the availability of both
dissolved oxygen and MEHQ inhibitor(CAS=150-76-5). The presence of
oxygen is necessary for the MEHQ to function effectively. The
product should never be stored under an inert gas atmosphere, but
should always be stored under an atmosphere containing 5-21% oxygen
by volume.
Conditions to Avoid:
Light, ignition sources, moisture, excess heat, loss of inhibitor.
Incompatibilities with Other Materials:
Strong oxidizing agents, strong reducing agents, acids, bases,
peroxides.
Hazardous Decomposition Products:
Carbon monoxide, carbon dioxide.
Hazardous Polymerization: May occur.
