**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable.Corrosive.Highly flammable.
Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Ingestion:
May cause severe gastrointestinal tract irritation with nausea,
vomiting and possible burns. May cause central nervous system
depression.
Inhalation:
May cause severe irritation of the respiratory tract with sore
throat, coughing, shortness of breath and delayed lung edema.
Exposure produces central nervous system depression. Inhalation may
be fatal as a result of spasm, inflammation, edema of the larynx and
bronchi, chemical pneumonitis and pulmonary edema. May cause an
allergic response. Vapors may cause dizziness or suffocation.
Chronic:
Repeated inhalation may cause nasal and tracheal inflammation.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
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 and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation.
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. During a
fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Use water spray to keep fire-exposed
containers cool. Water may be ineffective. Material is lighter than
water and a fire may be spread by the use of water. Flammable liquid
and vapor. May form explosive peroxides. Vapors may be heavier than
air. They can spread along the ground and collect in low or
confined areas. May polymerize explosively when involved in a fire.
Containers may explode when heated.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers. Water may be ineffective. For large fires, use water
spray, fog or alcohol-resistant foam. Do NOT use straight streams of
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. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Scoop up
with a nonsparking tool, then place into a suitable container for
disposal. Use water spray to disperse the gas/vapor. Remove all
sources of ignition. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Use only in a
well-ventilated area. Do not get in eyes, on skin, or on clothing.
Empty containers retain product residue, (liquid and/or vapor), and
can be dangerous. Keep away from heat, sparks and flame. Do not
ingest or inhale. If peroxide formation is suspected, do not open or
move container. Do not pressurize, cut, weld, braze, solder, drill,
grind, or expose empty containers to heat, sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Keep from contact with
oxidizing materials. Keep under an argon blanket. Store in a cool,
dry, well-ventilated area away from incompatible substances.
Flammables-area. Keep away from acids. Do not store near alkaline
substances. Keep away from strong bases. After opening, purge
container with nitrogen before reclosing. Periodically test for
peroxide formation on long-term storage. Addition of water or
appropriate reducing materials will lessen peroxide formation.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.
Exposure Limits
CAS# 123-72-8:
Germany: 20 ppm TWA; 64 mg/m3 TWA
Russia: 5 mg/m3 TWA
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 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.
