PASS 2 of 3 EFFECTS OP OVEREXPOSURE: Mild eye and skin irritation. Decomposition products and ftm.es from vulcanization and crosslinking operations may cause eye, skin, and respiratory irritation and may be skin sensitizers. See Hercules Bulletin ORC-204 for summary of toxicological Investigations. .EMERGENCY AND FIRST AID PROCEDURES: EYES: In ease of contact, luediately flush eyes with plenty of water for at least 15 minutes. Call a physician. SKIN: Hash thoroughly with soap and running water. Wash clothing before reuse. INHALATION: Remove to fresh air and, if indicated, give artificial respiration, preferably mouth-co-mouth. If breathing is difficult, give oxygen. Call a physician. Treat symptomatically. STABILITY UNSTABLE TfABLE VI. REACTIVITY DATA CONDITIONS TO AVOiO: Stable at room temperatures. Avoid temperaCuras above 55*C (131*?) or contact with materials listed below. X Higher temperatures or contact with listed materials promote exothermic decomposition. INCOMPATIBILITY (MATERIALS TO AVQlO):- Acids and acidic--type materials such as FriedelCrafts catalysts, strong oxidizing and reducing agents, and oxidation catalysts. Copper, copper alloys, lead and iron. HAZARDOUS DECOMPOSITION PROOUCTS: Acetephenbne, cumyl alcohol, a-methyl styrene, methane, and ethane. Under acidic decomposition conditions, phenols may also be formed. Combustion products include CO, C02, and generation of smoke. HAZARDOUS MAY OCCUR POLYMERIZATION WIU n6T OCCUR X CONDITIONS TO AVOIO: None VII. SPILL OR LEAK PROCEDURES STEPS TO BE TAKEN if MATERIAL IS RELEASED OR SPILLED: Salvage in clean, steel drums. Absorb excess in clean sand and place in dean, steal drums for disposal. waste DISPOSAL METHOD: Dispose of in accordance with local, state, and Federal regulations. VIII. SPECIAL PROTECTION INFORMATION RESPIRATORY PROTECTION (SPECIFY TYPE) None required in normal use. Use self-contained breathing apparatus in excessive fumes from product decomposition. VENTILATION LOCAL EXHAUST -- MECHANICAL (GENERAL) PROTECTIVE GLOVES: Chemical resistant SPECIAL dtHER Use adequate ventilation.

HEAT OR CONTAMINATION MAY CAUSE HAZARDOUS DECOMPOSITION. PRODUCT MAY CAUSE IRRITATION OF EYES AND SKIN. DECOMPOSITION PRODUCTS MAY CAUSE EYE, SKIN, AND RESPIRATORY. IRRITATION AND MAY BET SKIN SENSITIZERS. Do not heat above 55*C (131*F) or permit contact with acids and addle-type materials such as Friedel-Crafts catalysts, strong oxidizing and reducing agents or oxidation catalysts. Higher temperatures or contact with these materials cause rapid, self-accelerating heating, and decomposition that may cause container rupture and possible fire. Avoid contact with copper, copper alloy, lead, and iron as contact with these metals accelerates decomposition. Avoid contact with eyes, skin, and clothing. Avoid breathing vapors. Use with adequate ventilation. Wash thoroughly with soap and water after handling. FIRST AID; EYES - In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Call a physician. SKIN - Wash thoroughly with soap and running water. Wash clothing before reuse. INHALATION - Remove to fresh air and, if indicated, give artificial respiration, preferably mouth-to-mouth. If breathing is difficult, give oxygen. Call a physician. Treat symptomatically. STORAGE AND HANDLING: Store below 52*C (125*F) in original containers in a ventilated area out of direct sunlight and away from heat sources. SPILL OR LEAK: Salvage in clean steel drums. Absorb excess in clean sand and place in clean steel drums for disposal. Dispose of in accordance with local, state, and Federal regulations. BULK CONTAINER LABELS MELTING PROCEDURE: Melt by circulating hot water at 55*C (131*F) maximum temperature throush coils provided in container. Other heat sources such as ovens, hot rooms, immersion heaters, and direct flame or steam are not safe. Please refer to appropriate Hercules literature that offers a more comprehensive procedure for heating of this container. DRUM IABELS MELTING PROCEDURE: USE WATER BATH OR WATER COILS ONLY. Heat must be applied uniformly without creating localized hot spots that might exceed 55"C (131*F). Other heat sources such as ovens, hot plates, hot rooms, immersion heaters, and direct flame or steam are not safe. Please refer to appropriate Hercules literature that offers a more comprehensive procedure for heating of this container. NCR 24440*1 *7t DO 086375 CONF JDFNTTA1., 4R1MTRR M U.i.A.
