8.9.�Contr`o{ paarriters�i, , ;�Y n. <br />74-$2 <br />ACGIH p Not established <br />Rllthane, cQm res§ed -8} . <br />USA OSHA Not established <br />Methane (74-82-8}`', <br />ACGIH Not established <br />USA OSHA Not established <br />Appropriate engineering controls <br />Use an explosion -proof local exhaust system with sufficient flow velocity to maintain an <br />Appearance <br />adequate supply of air in the worker's breathing zone. Mechanical/General measures: Use in <br />Molecular mass <br />a closed system. <br />Eye protection <br />Wear safety glasses when handling cylinders; vapor -proof goggles and a face shield during <br />Odor <br />cylinder changeout or whenever contact with product is possible. Select eye protection in <br />Odor threshold <br />accordance with OSHA 29 CFR 1910.133. <br />Skin and body protection <br />Wear metatarsal shoes and work gloves for cylinder handling, and protective clothing where <br />Relative evaporation rate (butyl acetate=1) <br />needed. Wear neoprene gloves during cylinder changeout or wherever contact with product is <br />Relative evaporation rate (ether --1) <br />possible. Select per OSHA 29 CFR 1910.132, 1910.136, and 1910.138. <br />Respiratory protection <br />When workplace conditions warrant respirator use, follow a respiratory protection program that <br />Freezing point <br />meets OSHA 29 CFR 1910.134, ANSI Z88.2, or MSHA 30 CFR 72.710 (where applicable). <br />Boiling point <br />Use an air -supplied or air -purifying cartridge if the action level is exceeded. Ensure that the <br />Flash point <br />respirator has the appropriate protection factor for the exposure level. If cartridge type <br />Critical temperature <br />respirators are used, the cartridge must be appropriate for the chemical exposure (e.g., an <br />Auto -ignition temperature <br />organic vapor cartridge). For emergencies or instances with unknown exposure levels, use a <br />Decomposition temperature <br />self-contained breathing apparatus (SCBA). <br />Physical state <br />Gas <br />Appearance <br />Colorless gas. <br />Molecular mass <br />16.04 g/mol <br />Color <br />Colorless <br />Odor <br />No data available <br />Odor threshold <br />No data available <br />pH <br />Not applicable. <br />Relative evaporation rate (butyl acetate=1) <br />No data available <br />Relative evaporation rate (ether --1) <br />Not applicable. <br />Melting point <br />-182 °C <br />Freezing point <br />No data available <br />Boiling point <br />-161.5 °C <br />Flash point <br />-187.8 °C <br />Critical temperature <br />-82.5 <br />Auto -ignition temperature <br />600 °C <br />Decomposition temperature <br />No data available <br />Flammability (solid, gas) <br />5 - 15 vol % <br />Vapor pressure <br />Not applicable. <br />Critical pressure <br />4599 kPa <br />Relative vapor density at 20 °C <br />No data available <br />EN (English US) <br />SDS ID: P-4618 <br />This document is only controlled while on the Praxair, Inc. website and a copy of this controlled version is available for download. <br />Praxair cannot assure the integrity or accuracy of any version of this document after it has been downloaded or removed from our website. <br />4/9 <br />
