Use water spray curtain to divert vapor drift. Biminate all sources of ignition. Consider svacuating the spill or leak area immediately until ambient air sampling results indicate that the pentane vapor concentration is below the flammable range. Prevent entry into sewers, basements, or confined areas; dike if needed. Special Procedures Contact local policefemergency services and appropriate emergency telaphone numbers provided in Sectian 1. Ensure that statutory and regulatory reporting requirements in the applicable jurisdiction are met. Wear appropriate protective equipment and clothing during clean-up. Individuals without appropriate protective equipment should be excluded from area of spill until cleanup has been completed. Damaged or Suspect Damaged Containers oe If EPS containers are damaged or suspected to have baen damaged during transit, open the truck trailer door Slowly and ventilate for 15 minutes. Never permit smoking. Test the aimosphere to ensure the alr is free of pentane before entering. See Section & for recommended Personal Protective Equipment and see Saction 13 for waste disposal! considerations. | Section 7 - Handling and Storage Handling Procedures ‘Handle in contained and properly designed equipment systems. Use with adequate ventilation. Avoid Ingestion and inhalation. Keep this product from heart, sparks, it cigarettes, static electricity discharges or open flame Ground all material handling and transfer equipment to dissipate bulld-up of static electricity. Keep handling areas free of loose beads and dust accumulation, Mechanical operations Involving this material should be done In such @ manner as to prevent or minimize dust generation, Small amounts of fines or dust coniained in granular resins may accumulate in material handling systems. Wf permitted ta accumulate, these fines or dust can, under certain conditions, pose an explosion hazard, Every effort Should be made jo prevent suspension, concentration or accumutatlon of fines of dusts in, or around, material handling systems. For additional information on controt of Static and minimizing potential dust and firs hazards, refer to NFPA 654, "Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustibie Particulate Solids, 2006 Edition.” Spilled product may create a dangerous slipping hazard, Keep away from incompatibles such as oxidizing agents, and organic materials. Keep this material in a cool, well-ventilated place. After opening the container in a well-ventilated area, allow 15 minutes for the accumulated pentane fo dissipate. Partialty opened containers represent a potentlatly serious hazard because the insides of the container permit a Space for the pentane lo accumulats. When partially filled containers have to be used, direct a stream of air Into the container for 15 minutes after opening to ensure no accumulation of pentane in the container, Maintain Sufficient air circulation and ventilation to prevent flammable concentrationg from forming, especially in low-lying Brees.

Storage

Procedures Storage area should be clearly Identified, well-llluminated, and clear of obstruction. Adequate security must be setae provided so that unauthorized personnel do not have eccess to producl/ material. Store In grounded, properly designed and approved vessels and away fram incompatible materials. Store and use away from heat, sparks, lit clgarettes, static electricity discharges, open flame, or any other ignition source. Store according to applicable regulations for flammable materials for storage tanks, containers, piping, bulldings, rooms, cabinets, allowable quaniities and minimum storege distances, Use non-sparking ventilavion systems, approved sxpleslon-proof equipment, and intrinsically safe electrical systems. Have appropriate extinguishing capability in storage area (e.g. sprinkler system, portable fire extinguishers, flammable gas detactors). A refrigerated room Is generally arrest system when working hear open bulk storage containers. recommended for warehouse storage of materials with a fiash point lower than 37.8°C (100°F) Oe DO NOT enter filled bulk containers and attempt to walk over product, due to risk of sipping and possible suffocation.
