Carbon dioxide, refrigerated liquid <br /> PRi4X14IR Safety Data Sheet P-4573 <br /> Making ourplanetmoreproductive- This SIDS conforms to U.S. Code of Federal Regulations 29 CFR 1910.1200, Hazard Communication. <br /> Date of issue:01/01/1997 Revision date: 10/13/2016 Supersedes: 12/18/2014 <br /> SECTION 8: Exposure controls/personal protection <br /> 8.1. Control parameters <br /> Carbon dioxide,refrigerated liquid(124-38-9) <br /> ACGIH ACGIH TLV-TWA(ppm) 5000 ppm <br /> ACGIH ACGIH TLV-STEL(ppm) 30000 ppm <br /> USA OSHA OSHA PEL(TWA)(mg/m') 9000 mg/m' <br /> USA OSHA OSHA PEL(TWA)(ppm) 5000 ppm <br /> USA IDLH US IDLH(ppm) 40000 ppm <br /> 8.2. Exposure controls <br /> Appropriate engineering controls Oxygen detectors should be used when asphyxiating gases may be released. Ensure exposure <br /> is below occupational exposure limits(where available). <br /> Hand protection Wear working gloves when handling gas containers. <br /> Eye protection Wear goggles and a face shield when transfilling or breaking transfer connections.Wear safety <br /> glasses when handling cylinders;vapor-proof goggles and a face shield during cylinder <br /> changeout or whenever contact with product is possible. Select eye protection in accordance <br /> with OSHA 29 CFR 1910.133. <br /> Skin and body protection Wear metatarsal shoes and work gloves for cylinder handling,and protective clothing where <br /> needed. Wear appropriate chemical gloves during cylinder changeout or wherever contact with <br /> product is possible. Select per OSHA 29 CFR 1910.132, 1910.136,and 1910.138. Select per <br /> OSHA 29 CFR 1910.132, 1910.136,and 1910.138. <br /> Respiratory protection When workplace conditions warrant respirator use,follow a respiratory protection program that <br /> meets OSHA 29 CFR 1910.134,ANSI Z88.2,or MSHA 30 CFR 72.710(where applicable). <br /> Use an air-supplied or air-purifying cartridge if the action level is exceeded. Ensure that the <br /> respirator has the appropriate protection factor for the exposure level. If cartridge type <br /> respirators are used,the cartridge must be appropriate for the chemical exposure. For <br /> emergencies or instances with unknown exposure levels, use a self-contained breathing <br /> apparatus(SCBA). <br /> Thermal hazard protection Wear cold insulating gloves.Wear cold insulating gloves when transfilling or breaking transfer <br /> connections. <br /> SECTIONand chemical properties <br /> 9.1.
