REPEATED CONTACT CAN CAUSE MODERATE IRRITATION, DEFATTING,
DERMATITIS. INHALATION: EXCESSIVE INHALATION OF VAPORS CAN CAUSE
NASAL AND RESPIRATORYIRRITATION, CENTRAL NERVOUS SYSTEM EFFECTS
INCLUDING DIZZINESS,(EFTS OF OVEREXP)
Explanation of Carcinogenicity:STYRENE: IARC MONOGRAPH ON EVALUATION OF
CARCIN RISK OF CHEMS TO MAN, VOL 60, PG 233, 1994:GROUP 2B. ANIMAL:
SKIN.

Extinguishing Media:REGULAR FOAM OR WATER FOG OR CARBON DIOXIDE OR DRY
CHEMICAL.
Fire Fighting Procedures:USE NIOSH/MSHA APPROVED SCBA AND FULL
PROTECTIVE EQUIPMENT .
Unusual Fire/Explosion Hazard:VAPS ARE HVR/AIR & MAY TRAVEL ALONG
GROUND OR MAY BE MOVED BY VENT & IGNITED BY PILOT LIGHTS, OTHER
FLAMES, SPKS, HEATER, SMKNG, ELEC MOTORS, STATIC (SUPDAT)

Spill Release Procedures:SM SPILL:ABSORB LIQ ON VERMICULITE, FLOOR
ABSORB/OTHER ABSORB MATL & TRANSFER TO HOOD. LG SPILL:ELIM ALL
IGNIT SOURCES (FLARES, FLAMES INCL PILOT LIGHTS, ELEC SPKS).
PERSONS NOT WEARING PROT EQUIP SHO ULD BE EXCLUDED FROM AREA OF
SPILL UNTIL (ING 6)
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

Handling and Storage Precautions:CNTNRS OF MATL MAY BE HAZ WHEN
EMPTIED. SINCE EMTPIED CNTNRS RETAIN PROD RESIDUES (VAP, LIQ &/OR
SOLID) ALL HAZ PRECS GIVEN IN MSDS MUST BE OBSERVED.
Other Precautions:EXPOS TO AEROSOLS & MIST WHEN MATL IS SPRAYED MAY
PRESENT GREATER RISK OF INJURY FROM COMPONENTS BECAUSE HIGHER CONCS
ARE IN ATM THAN RSLT FROM VAP ALONE. PROVIDE ADEQ VENT & IF NEC,
USE NIOSH/MSHA AP PRVD RESP PROT.

Respiratory Protection:IF WORKPLACE EXPOS LIM(S) OF PROD/ANY COMPONENT
IS EXCEEDED, NIOSH/MSHA APPRVD AIR SUPPLIED RESP IS ADVISED IN
ABSENCE OF PROPER ENVIRON CTL. OSHA REGS ALSO PERMIT OTHER
NIOSH/MSHA APPRVD RESPS (NEG P RESS TYPE) UNDER SPECIFIED (ING 11)
Ventilation:PROVIDE SUFFICIENT MECHANICAL (GENERAL AND/OR LOCAL
EXHAUST) VENTILATION TO MAINTAIN EXPOSURE BELOW TLV(S).
Protective Gloves:RESISTANT SUCH AS POLYVINYL ALCOHOL.
Eye Protection:ANSI APPRVD CHEM WORKERS GOGGLES .
Other Protective Equipment:ANSI APPROVED EYE WASH & DELUGE SHOWER .
NORMAL WORK CLOTHING COVERING ARMS AND LEGS.
Work Hygienic Practices:NONE LISTED BY MANUFACTURER.
Supplemental Safety and Health
EXPLO HAZ: DISCHARGE OR OTHER IGNIT SOURCES AT LOCATIONS DIST FROM MATL
HNDLG POINT. ALL 5 GAL PAILS & LARGER METAL CNTNRS INCL TANK CARS &
TANK TRUCKS SHOULD BE GROUNDED &/OR BONDED WHEN MATL IS TRAN
SFERRED. NEVER USE WELDING/CUTTING TORCH ON/NEAR DRUM (EVEN EMPTY)
BECAUSE PROD (EVEN JUST RESIDUE) CAN IGNITE (ING 3)
