ISO 25760:2009适用于供应商、测试设施中的操作员、执行气瓶维护的操作员以及任何有权从气瓶上拆除阀门的人员。它详细说明了从钢瓶上安全拆除阀门的程序,并包括识别不可操作阀门的技术。
只有气体和气体混合物在压力下的风险得到解决;与从钢瓶上拆卸阀门有关的其他技术问题不包括在内。
部分天然气行业正在使用一些专用设备和程序,以便在受压时安全地从低压气瓶上拆下气瓶阀门,例如液化石油气(LPG);这些技术不包括在ISO 25760:2009中。
ISO 25760:2009 is intended for suppliers, operators in testing facilities, operators performing cylinder maintenance and any person authorized to remove valves from gas cylinders. It details procedures for the safe removal of valves from cylinders and includes techniques for the identification of inoperable valves.
Only the risks due to gas and gas mixtures under pressure are addressed; other technical issues relating to the removal of a valve from a cylinder are not covered.
Some specialized equipment and procedures are in use in parts of the gas industry to safely remove cylinder valves from low pressure gas cylinders while under pressure, e.g. liquefied petroleum gas (LPG); these techniques are not included in ISO 25760:2009.
