O. CArvaurIC liVN 1 MUL.0 - rr-MOU VAL rriv 1 CV 1 Iv1V VENTILATION AND ENGINEERING CONTROLS: Use with adequate ventilation. Carbon Dioxide accumulates in low- lying areas with limited air movement. Natural or mechanical ventilation should be available in the worker's breathing zone to prevent levels of Carbon Dioxide above exposure limits (see Section 2, Composition and Information on Ingredients). Local exhaust ventilation is preferred, because it prevents dispersion of this gas into the work place by eliminating it at its source. Areas of Carbon Dioxide use should be engineered to remove vapor from the lowest possible level and exhaust vapor to a well -ventilated area or to the outside. Carbon Dioxide levels should be monitored to assure levels are maintained below the TLV. If appropriate, install automatic monitoring equipment to detect the levels of Carbon Dioxide and of oxygen. RESPIRATORY PROTECTION: Maintain Carbon Dioxide levels below those listed in Section 2 (Composition and Information on Ingredients) and oxygen levels above 19.5% in the workplace. Use supplied air respiratory protection if Carbon Dioxide levels are above the IDLH (40,000 ppm) or during emergency response to a release of this product. If respiratory protection is required, follow the requirements of the Federal OSHA Respiratory Protection Standard (29 CFR 1910.134), or equivalent State standards. Respiratory selection guidelines from NIOSH for Carbon Dioxide are provided on the following page for further information on respiratory protection. CONCENTRATION RESPIRATORY EQUIPMENT UP TO 40,000 ppm: Supplied Air Respirator (SAR); or full-facepiece Self -Contained Breathing Apparatus (SCBA). EMERGENCY OR PLANNED ENTRY INTO UNKNOWN CONCENTRATIONS OR IDLH CONDITIONS: Positive pressure, full-facepiece SCBA; or positive pressure, full-facepiece SAR with an auxiliary positive pressure SCBA. ESCAPE: Escape -type SCBA. NOTE: The IDLH concentration for Carbon Dioxide is 40,000 ppm. EYE PROTECTION: Splash goggles, face -shields or safety glasses. Face -shields must be worn when using cryogenic Carbon Dioxide. HAND PROTECTION: Wear mechanically -resistant gloves when handling cylinders of Carbon Dioxide. Recommended use of low-temperature protective gloves (e.g. insulated polyvinyl chloride or insulated nitrile) when working with containers of Liquefied Carbon Dioxide. BODY PROTECTION: Use body protection appropriate for task. Transfer of large quantities under pressure may require protective equipment appropriate to protect employees from splashes of liquefied product, as well provide sufficient insulation from extreme cold. 9. PHYSICAL and CHEMICAL PROPERTIES GAS DENSITY @ 21 °C (70°F) and 1 atm: 0.1144 lb/ft' (1.833 kg/m3) LIQUID DENSITY @ 21.1 °C (70°F) and 838 psiq (5778 kPa): 47.35 Ib/ft3 (761.3 kg/m3) SOLID DENSITY @ -78.5°C (-109.30F): 97.59 Ib/ft3 (1569 kg /M3) SPECIFIC GRAVITY (gas) @ 21'C (70°F): 1.52 EVAPORATION RATE (nBuAc = 1): Not applicable SPECIFIC GRAVITY (solid) @ 0°C (320F): 1.54 FREEZING POINT: -56.6°C (-69.9°F) VAPOR PRESSURE (psia): 844.7 SPECIFIC VOLUME (ft3/Ib): 8.8 SOLUBILITY IN WATER @ 20°C (680F): 0.90% pH @ 1 atm: 3.7 (carbonic acid) ODOR THRESHOLD: Not applicable. TRIPLE POINT @ 60.4 psiq (416 kPa): -56.6°C (-69.9°F) EXPANSION RATIO: Not applicable. BOILING POINT @ 1 atm (sublimation point): -78.5°C (-109.3°F) COEFFICIENT WATER/OIL DISTRIBUTION: Not applicable. APPEARANCE AND COLOR: Carbon dioxide is a colorless to opaque, white solid; a colorless gas; or a colorless cryogenic liquid. All forms of Carbon Dioxide are odorless at low concentrations. At high concentrations, Carbon Dioxide will have a sharp, acidic odor. HOW TO DETECT THIS SUBSTANCE (warning properties): The odor is not a good warning property, as the asphyxiation properties of Carbon Dioxide may present a hazard before the odor at high concentrations is readily detectable. In terms of leak detection for the gas, fittings and joints can be painted with a soap solution to detect leaks, which will be indicated by a bubble formation. In conditions of high humidity, the solid form of Carbon Dioxide may release visible vapors. 10. STABILITY and REACTIVITY STABILITY: Normally stable. DECOMPOSITION PRODUCTS: Carbon Dioxide gas in an electrical discharge yields carbon monoxide and oxygen. In the presence of moisture, Carbon Dioxide will form carbonic acid.
