8. EXPOSURE CONTROLS - PERSONAL PROTECTION <br /> VENTILATION AND ENGINEERING CONTROLS: No special ventilation systems or engineering controls are <br /> needed under normal circumstances of use. As with all chemicals, use this product in well-ventilated areas. If <br /> this product is used in a poorly-ventilated area, install automatic monitoring equipment to detect the levels of <br /> oxygen. <br /> RESPIRATORY PROTECTION: No special respiratory protection is required under normal circumstances of <br /> use. Use supplied air respiratory protection if oxygen levels are below 19.5% or unknown during emergency <br /> response to a release of this product. If respiratory protection is required for emergency response to this product, <br /> follow the requirements of the Federal OSHA Respiratory Protection Standard (29 CFR 1910.134) or equivalent <br /> State standards. <br /> EYE PROTECTION: Safety glasses. <br /> HAND PROTECTION: No special protection is needed under normal circumstances of use. <br /> BODY PROTECTION: No special protection is needed under normal circumstances of use. <br /> 9. PHYSICAL and CHEMICAL PROPERTIES <br /> Unless otherwise specified, the following information is for Nitrogen, the main component of this gas <br /> mixture. <br /> GAS DENSITY @ 32°F(0°C) and 1 atm: 0.072 lbs/ft3(1.153 kg/m3) <br /> BOILING POINT: -195.8"C (-.320.4 'F) <br /> FREEZING/MELTING POINT @ 10 psig -210"C (-345.80F) <br /> SPECIFIC GRAVITY(air= 1)@ 70°F(21.10C): 0.906 pH: Not applicable. <br /> SOLUBILITY IN WATER vol/vol @ 32°F(0°C)and 1 atm: 0.023 MOLECULAR WEIGHT: 28.01 <br /> EVAPORATION RATE (nBuAc = 1): Not applicable. EXPANSION RATIO: Not applicable. <br /> ODOR THRESHOLD: Not applicable. SPECIFIC VOLUME (W/lb): 13.8 <br /> VAPOR PRESSURE @ 70°F(21.1°C) psig: Not applicable. <br /> COEFFICIENT WATER/OIL DISTRIBUTION: Not applicable. <br /> The following information is for this gas mixture. <br /> APPEARANCE AND COLOR: This product is a colorless, odorless gas. <br /> HOW TO DETECT THIS SUBSTANCE (warning properties): There are no unusual warning properties <br /> associated with a release of this product. <br /> 10. STABILITY and REACTIVITY <br /> STABILITY: Normally stable in gaseous state. <br /> DECOMPOSITION PRODUCTS: The thermal decomposition products of Isobutylene include carbon oxides. <br /> The other components of this gas mixture do not decompose, per se, but can react with other compounds in the <br /> heat of a fire. <br /> MATERIALS WITH WHICH SUBSTANCE IS INCOMPATIBLE: Titanium will burn in Nitrogen (the main <br /> component of this product). Lithium reacts slowly with Nitrogen at ambient temperatures. A component of this <br /> product (Isobutylene) are also incompatible with strong oxidizers (i.e. chlorine, bromine pentafluoride, oxygen <br /> difluoride, and nitrogen trifluoride). <br /> HAZARDOUS POLYMERIZATION: Will not occur. <br /> CONDITIONS TO AVOID: Contact with incompatible materials. Cylinders exposed to high temperatures or <br /> direct flame can rupture or burst. <br /> 11. TOXICOLOGICAL INFORMATION <br /> TOXICITY DATA: The following toxicology data are available for the components of this product: <br /> NITROGEN: There are no specific toxicology data for Nitrogen. ISOBUTYLENE: <br /> Nitrogen is a simple asphyxiant,which acts to displace oxygen in the LC5o(inhalation,rat)=620,000 mg/kg/4 hours <br /> environment. LC5o(inhalation,mouse)=415,000 mg/kg <br /> NON-FLAMMABLE GAS MIXTURE MSDS-50054 EFFECTIVE DATE: November 12,2002 <br /> PAGE 4 OF 7 <br />
