A=COM <br /> Americas <br /> Compressed Gases S3AM-114-PR1 <br /> 1.0 Purpose and Scope <br /> 1.1 This procedure provides the requirements for using, handling, storing, transporting, disposition and/or <br /> decommissioning compressed gas cylinders. <br /> 1.2 This procedure applies to all AECOM Americas based employees and operations and any other entity and <br /> its personnel contractually required to comply with this document's content. <br /> 2.0 Terms and Definitions <br /> 2.1 Compressed Air(Non-Breathable)—Air that is at a pressure greater than that of the atmosphere. <br /> Compressed air shall not be used for cleaning purposes except where reduced to less than 30 psi and then <br /> only with effective chip guarding and personal protective equipment. Utilized for tools, equipment, and <br /> mechanical machinery and cleaning purposes as described in this procedure. <br /> 2.2 Compressed Gas—Any material or mixture in a pressure vessel having: <br /> • An absolute pressure exceeding 40 pounds per square inch (PSI)at 70°F(25 pounds per square inch <br /> gauge); or <br /> • An absolute pressure exceeding 104 Psia at 130°F, regardless of the pressure at 70°F. <br /> 2.3 Cylinder—Pressure vessel designed for pressures higher than 40 Psia and having a circular cross section. <br /> 2.4 Decommission—The removal of a compressed gas cylinder from service by rendering it permanently <br /> unusable. <br /> 2.5 Disposition—Recycling,treatment, or disposal of a compressed gas cylinder and/or its contents. <br /> 2.6 Pneumatics—The use of pressurized air to affect mechanical motion for machinery, equipment and tools. <br /> 2.7 Psi—Pounds per square inch. <br /> 2.8 Psia—Pounds per square inch absolute(i.e., pressure in a container that would appear on an ordinary <br /> gauge plus the local atmospheric pressure [14.696 psi at sea level]), psig-pounds per square inch gauge. <br /> 2.9 Psig—Pounds per square inch gauge. The pressure in a vessel or container as registered on a gauge <br /> attached to the container. This reading does not include the pressure of the atmosphere outside the <br /> container. <br /> 2.10 Pressure Relief Valve—A device installed on most cylinders to prevent the rupture of a normally <br /> pressurized cylinder when it is inadvertently exposed to fire or high temperatures. <br /> 3.0 References <br /> 3.1 S3AM-003-PR1 SH&E Training <br /> 3.2 S3AM-116-PR1 Hazardous Materials Shipping <br /> 3.3 S3AM-127-PR1 Exposure Monitoring <br /> 3.4 S3AM-208-PR1 Personal Protective Equipment <br /> 3.5 S3AM-209-PR1 Risk Assessment&Management <br /> 3.6 S3AM-332-PR1 Hot Work <br /> Compressed Gases(S3AM-114-PR1) <br /> Revision 3 September 30,2020 <br /> PRINTED COPIES ARE UNCONTROLLED.
