Safety Data Sheet <br /> Material Name: Propane <br /> Section 8 - Exposure Controls / Personal Protection <br /> Component Exposure Limits <br /> Propane (74-98-6) <br /> ACGIH: 1000 ppm TWA(listed under Aliphatic hydrocarbon gases:Alkane C14) <br /> OSHA: 1000 ppm TWA; 1800 mg/m3 TWA <br /> NIOSH: 1000 ppm TWA; 1800 mg/m3 TWA <br /> Ethane (74-84-0) <br /> ACGIH: 1000 ppm TWA(listed under Aliphatic hydrocarbon gases:Alkane C1-4) <br /> Propylene (115-07-1) <br /> ACGIH: 500 ppm TWA <br /> Engineering Measures <br /> Use adequate ventilation to keep gas and vapor concentrations of this product below occupational exposure and <br /> flammability limits, particularly in confined spaces. Use explosion-proof equipment and lighting in <br /> classified/controlled areas. <br /> Personal Protective Equipment: Respiratory <br /> Use a NIOSH approved positive-pressure, supplied air respirator with escape bottle or self-contained breathing <br /> apparatus (SCBA)for gas concentrations above occupational exposure limits, for potential for uncontrolled <br /> release, if exposure levels are not known, or in an oxygen-deficient atmosphere. CAUTION: Flammability limits <br /> (i.e., explosion hazard) should be considered when assessing the need to expose personnel to concentrations <br /> requiring respiratory protection. <br /> Personal Protective Equipment: Hands <br /> Use cold-impervious, insulating gloves where contact with liquid may occur. <br /> Personal Protective Equipment: Eyes <br /> Where there is a possibility of liquid contact, wear splash-proof safety glasses and face shield. <br /> Personal Protective Equipment: Skin and Body <br /> Where contact with liquid may occur, wear appropriate cold insulating protective clothing and face shield. <br /> Section 9 - Physical & Chemical Properties <br /> Appearance: Colorless Odor: Odorless <br /> Physical State: Gas pH: ND <br /> Max Vapor Pressure: 208 psig @ 100 °F(37.8 °C) Vapor Density: 1.56 @ 32°F(0°C) <br /> Boiling Point: -43.8'F (-42.1'C) Molecular Weight: 44.096 <br /> Solubility (H2O): Slight(0.1 to 1.0%) Specific Gravity: 1.52 (Air= 1) <br /> Expansion Ratio: 1 to 270 (from liquid to gas @ 14.7 psia) Burning Rate: ND <br /> Evaporation Rate: ND VOC: ND <br /> Octanol/H20 Coeff.: ND Flash Point: -156°F (-104 °C) <br /> Flash Point Method: PMCC Auto Ignition: 842°F (450°C) <br /> Upper Flammability Limit (UFL): 9.6% <br /> Lower Flammability Limit (LFL): 2.15% <br /> Page 4 of 8 Revision Date 03/20/2017 <br />
