Routes of Entry: Inhalation:YES Skin:YES Ingestion:NO
Reports of Carcinogenicity:NTP:YES IARC:YES OSHA:YES
Health Hazards Acute and Chronic:INHALATION-IRRITATION TO THE MUCOUS
MEMBRANES OF THE UPPER RESPIRATORY TRACT MAY OCCUR. SKIN-IRRITATION
MAY OCCUR, WITH PROLONGED OR REPEATED EXPOSURE POSSIBLY DEVELOPING
TO DERMATITIS. ECZEMA MAY DEV ELOP. INGESTION-ASPIRATION OF STYRENE
INTO THE LUNGS MAY CAUSE CHEMICAL PNEUMONIA WHICH MAY BE LIFE
THREATENING.
Explanation of Carcinogenicity:STYRENE IS POSSIBLY CARCINOGENIC.
Effects of Overexposure:INHALATION-MAY CAUSE DROWSINESS, NAUSEA,
HEADACHE, FATIGUE, NARCOSIS, DIZZINESS & INCOORDINATION. SEVERE
EXPOUSRE MAY CAUSE A CONFUSED STATE. EYE-IRRITATION OF THE MUCOUS
MEMBRANES, PAIN & REDNESS MAY OCCUR. INGESTION-SORE THROAT,
ABDOMINAL PAIN AND VOMITING MAY OCCUR.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH CHRONIC
RESPIRATORY CONDITIONS (IE: ASTHMA, CHRONIC BRONCHITIS, EMPHYSEMA,
ETC) MAY BE ADVERSELY AFFECTED BY ANY FUME OR AIRBORNE PARTICULATE
MATTER EXPOSURE.

First Aid:INHALATION: REMOVE FROM EXPOSURE. IF BREATHING IS STOPPED OR
IS DIFFICULT, ADMINISTER ARTIFICIAL RESPIRATION OR OXYGEN AS
INDICATED. SKIN: REMOVE CONTAMINATED CLOTHING. WASH SKIN THOROUGHLY
WITH SOAP AND WATER. EYE: FLUSH WITH LARGE AMOUNTS OF LUKEWARM
WATER, LIFT UPPER AND LOWER EYELIDS OCCASIONALLY. INGEST: DO NOT
INDUCE VOMITING. CALL A PHYSICIAN.

Flash Point Method:PMCC
Flash Point:90.0F,32.2C
Lower Limits:1.1
Upper Limits:6.1
Extinguishing Media:CARBON DIOXIDE, DRY CHEMICAL (SMALL FIRES); ALCOHOL
FOAM AND WATER FOG (LARGE FIRES). WATER MAY BE INEFFECTIVE.
Fire Fighting Procedures:COOL TANKS AND DRUMS WITH WATER. FIREFIGHTERS
SHOULD WEAR SELF-CONTAINED BREATHING EQUIPMENT AND PROTECTIVE
CLOTHING.
Unusual Fire/Explosion Hazard:HIGH TEMPERATURE EXPOSURE FOR EXTENDED
PERIODS OF TIME WILL RESULT IN SPONTANEOUS UNCONTROLLED EXOTHERMIC
POLYMERIZATION.

Spill Release Procedures:REMOVE ALL IGNITION SOURCES & OPEN FLAMES.
INCREASE VENTILATION TO MAXIMIZE VAPOR DISPERSAL. DIKE LARGE SPILLS
TO PREVENT RUNOFF INTO SEWERS OR WATERWAYS. COVER SPILL WITH
INORGANIC ABSORBENT. SWEEP U P AND PLACE IN LABELED DRUM. REPORT
STYRENE SPILL.

Handling and Storage Precautions:STORE IN COOL DRY AREA AWAY FROM
OXIDIZERS. DO NOT STORE IN DIRECT SUNLIGHT. WORK W/ADEQUATE GENERAL
& LOCAL EXHAUST VENTILATION TO MINIMIZE EXPOSURE.
Other Precautions:BOND & GROUND CONTAINERS FOR TRANSFER OF THIS PRODUCT
TO PREVENT STATIC SPARKS. STYRENE VAPORS ARE UNHIBITED & MAY CAUSE
BLOCKAGE OF VENTILATION VENTS DUE TO POLYMERIZATION. PERIODIC
INSPECTION MAY BE NECESSARY TO PREVENT BLOCKAGE.

Respiratory Protection:RESPIRATORY PROTECTION APPROVED BY NIOSH/MSHA
FOR PROTECTION AGAINST ORGANIC VAPORS SHOULD BE USED TO AVOID
INHALATION OF EXCESSIVE AIR CONTAMINANTS. APPROPRIATE RESPIRATOR
SELECTION DEPENDS ON THE TY PE AND MAGNITUDE OF EXPOSURE.
Ventilation:LOCAL EXHST VENTILATION TO CONTROL EMISSION OF AIR
CONTAMINANTS. GENERAL DILUTION VENTILATION TO REDUCE
CONCENTRATIONS.
Protective Gloves:POLYVINYL ALCOHOL, POLYETHYLENE TYPE.
Eye Protection:CHEMICAL SAFETY GLASSES OR FACE SHIELD.
Other Protective Equipment:POLYVINYL ALCOHOL OR POLYETHYLENE TYPE
CLOTHES. EYEWASH STATION AND DELUGE SAFETY SHOWERS BE AVAILABLE IN
WORK AREA.
Work Hygienic Practices:AVOID PROLONGED OR REPEATED CONTACT WITH THE
SKIN. AVOID EYE CONTACT.
Supplemental Safety and Health
