SECTION 2 - HAZARD(S) IDENTIFICATIONPOTENTIAL HEALTH EFFECTS (See Section 11 for toxicological data.)EYE:Mechanical irritant.Sf\lN:Possible drying resulting in dermatitis,INGESTION:No adverse effects,INHALATION:Acuie (short term) exposure to dust levels exceeding the PEL may cause irritation of respira-tory tract resulting in a dry cough, Chronic (long term) exposure to airborne SMC dust containing respirablesize (=10J-l) quarter particles, where respirable quartz particle levels are higher than TLVs, may lead to de-velopment of silicosis or other respiratory problems, Persistent dry cough and labored breathing upon exer-tion may be symptomatic,CARCINOGENICITY:SMC is not listed by ACGIH, IARC, NTP, or OSHA IARC, 1997, concludes that thereis sufficient evidence in humans for the carcinogenicity of inhaled crystalline silica from occupationalsources (IARC Class 1), that carcinogenicity was not detected in all industrial circumstances studied andthat carcinogenicity may depend on characteristics of the crystalline silica or on external factors affecting itsbiological activity, NTP classifies respirable crystalline silica as "known to be a human carcinogen" (NTP9th Report on Car-cinogens - 2000), ACGIH classifies crystalline silica quartz as a suspected human car-cinogen (A2).NOTE: Polyester Staple is a family of fiber products having similar hazard and physical property character-istics, The polymer immobilizes the constituents of the polymer system (delusterants, catalyst residues,etc.) which, therefore, present no likelihood of exposure under normal conditions of processing and han-dling

SECTION 16 - OTHER INFORMATIONMSDS STATUS: Revised to '16 Section format.

OTHER FLAMMABILITY INFORMATION: Mechanical handling can cause formation of dusts. To reducethe potential for elust explosion, do not permit dust to accumulate. Material can be ignited by static dis-charge. Electrically ground all equipment. Do not permit dust to accumulate. Dust layers can be ignitedby spontaneous combustion or other ignition sources. When suspended in air dust can pose an explosionhazard.EXTINGUISHING MEDIA: Water, carbon dioxide and dry chemical.FIRE FIGHTING INSTRUCTIONS: Keep people away. Isolate fire area and deny unnecessary entry.Soak thoroughly with water to cool and prevent re-ignition. Cool surroundings with water to localize firezone. Hand held carbon dioxide or dry chemical hazard may result from forceful application of fire extin-guishing agents.PROTECTIVE EQUIPMENT FOR FIRE FIGHTERS: Wear positive-pressure self-contained breathing ap-paratus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, pants, boots, andgloves). If protective equipment is not available or not used, fight fire from a protected location or safe dis-tance.

ACCIDENTAL RELEASE MEASURES (See Section 15 for Regulatory Information)PROTECT PEOPLE: Material becomes slippery when wet.PROTECT THE ENVIRONMENT: Contain spilled material to prevent contamination of soil, surface wateror ground water.CLEANUP: Spills should be cleaned up immediately lIsing care to minimize generation of airborne dust.
