3. Hazards Identification
Routes of Entry:
Skin Contact: Moderate Eye Contact: Minor Ingestion: Major Inhalation: Major
Emergency Overview: Central nervous system depressant. High vapour concentration may
cause headache, nausea, dizziness, drowsiness and confusion. Causes skin and eye irritation.
Aspiration hazard. Swallowing or vomiting of the liquid may result in aspiration into the lungs.
Acute Health Effects: INHALATION: Liquid or spray mist may produce tissue damage on
mucous membranes of mouth and respiratory tract. Inhalation of the spray mist may produce
severe irritation of respiratory tract, characterized by coughing, choking, or shortness of breath.
Respiratory irritation is the most commonly reported effect. High concentrations cause depression

of the central nervous system (CNS) with symptoms such as drowsiness, headache, confusion,
incoordination and unconsciousness.
SKIN CONTACT: Very slightly to slightly dangerous in case of skin contact. May cause skin
sensitization.
EYE CONTACT: Liquid or spray mist may produce tissue damage on mucous membranes of
eyes. Very slightly to slightly dangerous in case of eye contact. May cause eye irritation.
INGESTION: Ingestion may cause effects similar to those experienced under the heading
鈥淚NHALATION鈥?
Chronic Health Effects: Carcinogenic: Classified 2B (Possible for human) by IARC (Styrene).
Repeated exposure to a highly toxic material may produce general deterioration of health by an
accumulation in one or many human organs. An increased incidence of lung tumours observed in
mice from a recent inhalation study. The relevance of this finding is uncertain since data from
other long-term animal studies and from epidemiology studies of workers exposed to styrene do
not provide a basis to conclude that styrene is carcinogenic. Lung effects have been observed in
the mouse following repeated exposure.
Medical Conditions Aggravated by Exposure:
Pre-existing eye, skin, respiratory tract disorders may be aggravated by exposure.
4. First Aid Measures
INHALATION: This product is flammable. Take proper precautions. Remove victim to fresh air.
Give artificial respiration if indicated. Get medical attention.
SKIN CONTACT: Avoid direct contact. Wear chemical protective clothing, if necessary. Quickly
and gently blot or brush away excess chemical. Wash gently and thoroughly with water and non-
abrasive soap for 20 minutes or until chemical is removed. Under running water, remove
contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Completely
decontaminate clothing, shoes and leather goods before re-use or discard. If the contact is
severe and pain persists after long term rinsing with water, rinse the contaminated area with
lukewarm pasteurized milk. After pain has stopped, rinse thoroughly with water. Obtain medical
attention immediately.
EYE CONTACT: MAY CAUSE EYE IRRITATION. Check and remove any contact lenses. Flush
with plenty of water for at least 20 minutes, occasionally lifting the upper and lower eyelids. DO
NOT INTERUPT FLUSHING. Take care not to contaminate non-affected eye. Seek medical
attention.
INGESTION: If patient is conscious, give three or four glasses of water. Do not induce vomiting
Do not give anything by mouth to a convulsing or unconscious person. Get medical attention.
GENERAL COMMENTS: Good personal hygiene is essential. Avoid eating, smoking or drinking
in work areas.

31oC (88掳F) TCC
Flash point:
490oC (914掳F). See information under 鈥淔ire Fighting
Autoignition Temperature:
Instructions鈥?
0.88 % by volume
Lower Explosive Limit:
8.8% by volume
Upper Explosion Limit:
No
Sensitivity to Impact:
No
Sensitivity to Static Discharge:
Hazardous Combustion Products: Burning may produce oxides of carbon.
Extinguishing Media: Use carbon dioxide, alcohol foam, or dry chemical. Water should be used
to cool surrounding containers.
Fire Fighting Instructions: Vapour will flash and the liquid will burn. Keep away from all
sources of ignition and avoid elevated temperatures. Vapours are heavier than air, and may
collect in low-lying areas. Firefighters must wear self-contained breathing apparatus and full
protective clothing.
6. Accidental Release Measures
Personal Protection: Wear adequate personal protection to prevent skin contact. See Section 8
for specific recommendations
Environmental Precautions: Prevent release into waterways and sewers. Stop spill as soon as
possible to prevent contamination of soil, groundwater, or surface water.
Cleanup Procedures: Poisonous, flammable liquid, insoluble or very slightly soluble in water.
Keep away from heat. Keep away from sources of ignition. Stop leak if without risk. Absorb with
DRY earth, sand, or other non-combustible material. Prevent entry into sewers, basements, or
confined areas. Dike if needed. Eliminate all sources of ignition. Call for assistance on disposal.
Consult national, provincial, and local regulations.
7. Handling and Storage
Handling Procedures: Keep away from heat and all sources of ignition. Ground all equipment
containing material. Do not ingest. Do not breath gas, fumes, vapor, or spray. Follow safe work
procedures and wear appropriate personal protective equipment.
Storage: Keep well away from all sources of ignition. Store in a cool well-ventilated area out of
direct sunlight and away from heat and ignition sources. Do not store near foodstuffs. Styrene
should not be stored for longer than 3 months. Containers should be checked weekly after 30
days to determine inhibitor concentration and possible polymerization. Store away from oxidizers
and corrosives and other incompatible materials such as sulfuric acid, peroxides, alkali metal,
which increase the risk of fire and explosion.

8. Exposure Controls, Personal Protection
Engineering Controls: If used indoors, ensure adequate non-sparking ventilation. Remove all
sources of ignition and post 鈥淣o Smoking鈥? signs in the work place. Keep away from heat, and
never weld, cut, or solder empty containers. Use adequate ventilation to reduce concentration to
below TLV.
Respiratory Protection: Use a NIOSH approved organic vapour respirator if concentration
below minimum IDLH of 500 ppm in the workplace. For vapour concentrations in excess of 500
ppm, use a positive pressure respirator.
Skin Protection: Wear impervious gloves (butyl rubber) and clothing to prevent skin contact.
Eye and Face Protection: Chemical splash-proof goggles must be worn at all times.
Other: Eye wash station should be located near work area.

10. Stability and Reactivity
Chemical Stability: This product is stable.
Hazardous Polymerization: May polymerize violently with risk of fire and explosion. Uninhibited
styrene, or styrene with low inhibitor concentration, polymerizes slowly at room temperature and
on exposure to light and air, and readily at elevated temperatures, greater than 65藲C (149藲F).
Polymerization becomes self-sustaining above 95掳C (203掳F). Metal salts (e.g. ferric or aluminum
chloride), peroxides, oxidizers and strong acids may also cause polymerization.
Conditions to Avoid: Elevated temperatures, heat, sparks, open flame and other ignition
sources.
Incompatibility: Oxygen, oxidizing agents - Increased risk of fire and explosion. Can form
explosive peroxides. Strong acids (e.g. sulfuric acid, oleum, chlorosulfonic acid) 鈥? Increased
temperature and pressure; increased risk of fire and explosion. Alkali metal, graphite
compounds, metallic halide salts, peroxides (dibenzoyl peroxide di-tertbutyl peroxide),
azoisobutyronitrile 鈥? Can initiate polymerization. Byllithium - Explosion can occur. Halogens - Can
react with low concentrations of halogens, in the presence of UV light, to form a strong irritant.
Can form peroxides in the presence of light and air or on contact with acids. Styrene monomer
has been involved in several plant-scale explosions when stored inappropriately or accidentally
heated.
Hazardous Decomposition Products: Styrene oxide.
