8. EXPOSURE CONTROLS -PERSONAL PROTECTION 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 workers breathing zone to prevent levels of Carbon Dioxide above exposure limns (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 swell-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 tt Carbon Dioxide levels are above the IDLH (40,000 ppm) ar during emergency response to a release of this product. If respiratory protection is needed, use only protection authorized In the U.S. Federal OSHA Standard (29 CFR 1910.134), applicable U.S. State regulations, or the Canadian CSA Standard 294.493 and applicable standards of Canadian Provinces. Oxygen levels below 19.5% are considered IDLH by OSHA. In such atmospheres, use of a full-facepiece pressure/demand SCBA or a full facepiece, supplied air respirator with auxiliary self-contained air supply is required udder OSHA's Respiratory Protection Standard (1910.1341998). The following are NIOSH respiratory protective equipment recommendations for Carbon Dioxide concentrations in air and are provided for further information: 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 positve pressure SCBA. ESCAPE: Escape-type SCBA. EYE PROTECTION: Splash goggles, face-shields or safety glasses. Face-shields must be wom when using cryogenic Carbon Dioxide. If necessary, refer to U.S. OSHA 29 CFR 1910.133, or Canadian Standards. HAND PROTECTION: Wear mechanically-resistant gloves when handling cylinders of Carbon Dioxide. Recommended use of low-temperature protective gloves (e.g. insulated polyvirryl chloride or insulated nitdle) when working with containers of Liquefied Carbon Dioxide. Wear thermally insulating gloves when handling Dry Ice. BODY PROTECTION: Use body protection appropriate Tor 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.

APPEARANCE AND COLOR: Carbon dioxide is a colorless to opaque, white slid; a coloriess gas; or a colorless cryogenic liquid. All forms of Carbon Dioxide are odorless at low concentrations. At high concenVations, Carbon Dioxide will have a sharp, acidic odor. HOW TO DETECT THIS SUBSTANCE (wamina orooerties): 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. Colorimetric tubes are available for the detection of Carbon Dioxide. 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. CARBON DIOXIDE - COZ MSDS (oocuMer+t aootots( PAGE 7 OF 12
