EMERGENCY OVERVIEW
Appearance: clear, colorless liquid. Flash Point: 32 deg C.
Warning! May polymerize explosively on loss of
inhibitor. Flammable liquid and vapor.
May cause eye, skin, and respiratory tract irritation. Aspiration
hazard if swallowed. Can enter lungs and cause damage. May cause
central nervous system depression. May cause cancer based on animal
studies. This material has been reported to be susceptible to
autoxidation and therefore should be classified as peroxidizable.
Hazardous due to peroxide initiation of polymerization. May cause
reproductive and fetal effects.
Target Organs: Central nervous system.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
May be absorbed through the skin in harmful amounts. Prolonged
and/or repeated contact may cause defatting of the skin and
dermatitis.
Ingestion:
May cause central nervous system depression, characterized by
excitement, followed by headache, dizziness, drowsiness, and nausea.
Advanced stages may cause collapse, unconsciousness, coma and
possible death due to respiratory failure. Aspiration of material
into the lungs may cause chemical pneumonitis, which may be fatal.
Inhalation:
Aspiration may cause respiratory swelling and pneumonitis. Causes
narcotic effects including headache, dizziness, weakness,
unconsciousness, and possible death.
Chronic:
No information found.
|
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:
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. Wash clothing before reuse.
Ingestion:
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
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:
Treat symptomatically and supportively.
|
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.
Flammable Liquid. Can release vapors that form explosive mixtures at
temperatures above the flashpoint. Containers may explode in the heat
of a fire.
Extinguishing Media:
This material is lighter than water and insoluble in water. The fire
could easily be spread by the use of water in an area where the water
cannot be contained. Use water fog, dry chemical, carbon dioxide, or
regular foam.
Flash Point: 32 deg C ( 89.60 deg F)
Autoignition Temperature: 490 deg C ( 914.00 deg F)
Explosion Limits, Lower:1.1% v/v
Upper: 7.0% v/v
NFPA Rating:
(estimated) Health: 2; Flammability: 3; Instability: 2
|
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. Use a
spark-proof tool. Provide ventilation.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Ground and
bond containers when transferring material. Use spark-proof tools and
explosion proof equipment. Avoid contact with skin and eyes. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Take precautionary measures against static discharges.
Avoid ingestion and inhalation. Wash clothing before reuse. 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 cool place in the
original container and protect from sunlight. Keep refrigerated.
(Store below 4癈/39癋.) Keep containers tightly closed.
|
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.

exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
Respirators:
Follow the OSHA respirator regulations found in 29

Section 10 - Stability and Reactivity
|
Chemical Stability:
Stable under normal temperatures and pressures. May form peroxides
in the absence of inhibitors.
Conditions to Avoid:
Incompatible materials, ignition sources.
Incompatibilities with Other Materials:
Vapor is explosive when exposed to heat or flame and reacts with
oxygen at temperatures above 104 F, unhibited material may form
explosive peroxides. Uninhibited material may polymerize which
becomes self-sustaining at temperatures above 65 C. Exposure to
butyllithium, dibenzoyl peroxide, azoisobutyronitrile or
di-tert-butylperoxide may cause violent polymerization. Violent
reaction with chlorosulfonic acid, oleum, sulfuric acid and
oxidizers. Oxygen + heat is explosive.
Hazardous Decomposition Products:
Carbon monoxide, carbon dioxide.
Hazardous Polymerization: May occur.

Environmental:
Styrene does not absorb solar radiation at wavelengths above the
solar cutoff (approximately 300 nm); therefore, it will not be
directly photolyzed in the lower atmosphere (troposphere) or surface
water. However, styrene is expected to be involved in indirect
photochemical reactions. Styrenes have been found to be very active
generators of photochemical smog.
Physical:
Styrene released to soil is subject to biodegradation. Volatilization
and biodegradation are important transport and degradation processes
respectively for styrene in water.
Other:
No information available.
