Fire Fighting MeasuresFlammability of theProductAuto-ignitionTemperatureFlash Points_Since the product is a gas and that it is mostly probable that it will be inhaled morethan ingested, please consider first to look at the preventive measures in case ofinhalation.Flammable.450°C (842°F)CLOSED CUP: -136.11°C (-213°F). (Tagliabue.).Flammable LimitsProducts of CombustionFire Hazards in Presenceof Various SubstancesExplosion Hazards inPresence of VariousSubstancesFire Fighting Mediaand InstructionsProtective Clothing (Fire)Special Remarks onExplosion HazardsLower: 2.3%Upper: 36%These products are carbon oxides (CO, CO2).Extremely flammable in presence of open flames and sparks, heat, or static. Protectcontainers from physical damage and static discharge.Risks of explosion of the product in presence of static discharge: Expected.Risks of explosion of the product in presence of mechanical impact: Not expected.Flammable gas.SMALL FIRE: Use DRY chemicals, CO2, alcohol foam or water spray.LARGE FIRE: Use water spray, fog or foam. DO NOT use water jet. Move containingvessels from fire area if without risk. Cool containing vessels with flooding quantities of wateruntil well after fire is out. Cool containing vessels with water jet in order to prevent pressurebuild-up, autoignition or explosion. DO NOT extinguish a leaking gas flame unless leak canbe stopped. Extinguish secondary fire. Handle damaged cylinders with extreme care.Wear MSHA/NIOSH approved self-contained breathing apparatus or equivalent and fullprotective gear.Forms explosive mixtures with air. Container may explode in fire. Flashback along vapor trailmay occur. May explode if ignited in an enclosed area.Section 6. Accidental Release MeasuresSmall Spill and LeakLarge Spill and LeakSection 7. Handling and StorageHandlingStorageWarn personnel to move away. Try to stop the gaseous leak by taping the container with anappropriate material (tape, stretched plastic). Shut off all ignition sources: No flares, flamesor smoking in hazard area. Use water spray to reduce vapors. Isolate area until gas isdispersed.Flammable gas. Isolate area until gas has dispersed. Warn personnel to move away. Letevaporate. If possible, turn leaking container so that gas escapes rather than liquid. Do notdirect water at spill or source. Use water spray curtain to divert vapor drift. Prevent entry intosewers, basements or confined areas. Eliminate all ignition sources.Keep away from heat. Keep away from sources of ignition. In case of insufficient ventilation,wear suitable respiratory equipment. Keep container tightly closed and in a well-ventilatedplace. Keep away from incompatibles such as oxidizing agents, acids. Ground allequipment containing material. Take precautionary measures against electrostatic discharges.Keep container in a cool, well-ventilated area. Keep container tightly closed and sealed untilready for use. Segregate from oxidizing materials. Avoid all possible sources of ignition(spark or flame). Take precautionary measures against static discharges. Ground allequipment containing material.Storage facilities for bulk quantities of light hydrocarbons, like ethylene, are highly specialized.Qualified engineering firms should be employed for the design and construction.Total Petrochemicals & Refining USA, Inc.

Exposure Controls/Personal Protection_Engineering ControlsUse process enclosures, local exhaust ventilation or other engineering controls to keepworker exposure to airborne contaminants below any recommended or statutory limits.Personal ProtectionProtective Clothing(Pictograms)Eyes Safety glasses with side shields. When handling liquid ethylene, a face shield isrecommended.Body Flame retardant clothing (FRC) required.Respiratory Use appropriate respiratory protection if there is a risk of exceeding any exposure limits.Hands If a liquid, then chemical resistant thermal insulating gloves are recommended.Feet Shoes.Personal Protection inCase of a Large SpillProduct NameSplash goggles. Full suit. Boots. Chemical resistant thermal insulating gloves. Suggestedprotective clothing might not be sufficient; consult a specialist BEFORE handling this product.Be sure to use a MSHA/NIOSH approved respirator or equivalent at high concentrations.Exposure LimitsEthylene ACGIH TLV (United States, 2011).TWA: 200 ppm 8 hour(s).Consult local authorities for acceptable exposure limits.Section 9.
