Health Hazards Acute and Chronic:INHALATION: MAY CAUSE DROWSINESS,
NAUSEA, HEADACHE, FATIGUE, NARCOSIS & DIZZINESS. SEVERE EXPOSURE
MAY CAUSE A CONFUSED STATE. IRRITATION OF THE MUCOUS MEMBRANES OF
THE UPPER RESPIRATORY TRACT MAY OCC UR. SKIN: IRRITATION MAY OCCUR
WITH PROLONGED EXPOSURE, POSSIBLY DEVELOPING TO DERMATITS. IF
ECZEMATOUS DEVELOPS, THIS *
Effects of Overexposure:*MOST OFTEN OCCURS ON THE BACKS OF THE HANDS,
WRISTS AND FOREARMS. MAY BE ABSORBED THROUGH THE SKIN.
EYE:IRRITATION OF THE MUCOUS MEMBRANES, PAIN AND REDNESS MAY OCCUR.
INGESTION: SORE THROAT, ABDOMIN AL PAIN AND VOMITING MAY OCCUR.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH CHRONIC
RESPIRATORY CONDITIONS (I.E., ASTHMA, CHRONIC BRONCHITIS,
EMPHYSEMA, ETC.) MAY BE ADVERSELY AFFECTED BY ANY LUME OR AIRBORNE
PARTICULATE MATTER EXPOSURE.

First Aid:INHALATION: REMOVE FROM EXPOSURE. IF BREATHING IS STOPPED OR
DIFFICULT, GIVE ARTIFICIAL RESPIRATION OR OXYGEN AS INDICATED. SEEK
MEDICAL AID. SKIN: REMOVE CONTAMINATED CLOTHING. WASH SKIN
THOROUGHLY W /SOAP & WATER. IF IRRITATION OCCURS, SEEK MEDICAL AID.

AND WATER FOG (LARGE FIRES).
Fire Fighting Procedures:COOL TANKS AND DRUMS WITH WATER. FIREFIGHTERS
SHOULD WEAR SELF-CONTAINED BREATHING EQUIPMENT.
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 AND OPEN FLAMES.
INCREASE VENT TO MAXIMIZE VAPOR DISPERSAL. DIKE LARGE SPILLS TO
PREVENT RUNOFF INTO SEWERS OR WATERWAYS. COVER SPILL W/INORGANIC
ABSORBENT MATERIAL (VERMIC ULITE). SWEEP UP AND PLACE IN LABELLED
DRUM.

Handling and Storage Precautions:AVOID CONTACT W/SKIN & EYES. STORE IN
A COOL, DRY AREA. DO NOT STORE IN DIRECT SUNLIGHT. WORK W/ADEQUATE
VENT TO MINIMIZE VAPOR EXPOSURE.
Other Precautions:BOND & GROUND CONTAINERS FOR TRANSFER OF THIS PRODUCT
TO PREVENT STATIC SPARKS. STYRENE VAPORS ARE UNINHIBITED & 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:USE LOCAL EXHST VENT TO CONTROL EMISSION OF AIR CONTAM.
GENERAL DILUTION VENT MAY ASSIST W/REDUCTION OF AIR CONTAM CONC.
Protective Gloves:CHEMICAL RESISTANT.
Eye Protection:CHEMICAL SAFETY GLASSES & FACE SHIELD.
Other Protective Equipment:EMERGENCY EYE WASH STATION AND DELUGE SAFETY
SHOWERS SHOULD BE AVAILABLE IN WORK AREA.
