1.1 本指南涵盖了机械冷冻柜和液氮冷冻柜中低温储存的材料搬运的推荐程序。 1.2 本指南涵盖了实施程序以确保充分库存控制的建议。 1.3 本指南涵盖了实施低温储存材料保护程序的建议。 1.4 本指南不包括本指南所涵盖的低温储存设备和设施的开发或维护 E1564 . 1.5 本指南不包括实践中涉及的冷冻保存实践 E1342 . 1.6 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.7 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 4.1 正确处理低温下储存的材料可确保不包括敏感生物材料的稳定性。 4.2 正确设计的库存控制系统确保最大限度地利用冷冻室空间，所有材料都可以轻松定位，任何物品都可以轻松取回，而不会影响冷冻室内其他物品的稳定性。 4.3 正确设计的安全和安保程序确保在低温下储存的材料在储存过程中不被包含，并且如果材料因冷冻柜故障或操作问题而丢失，则可以使用替代材料（见指南） E1566 ).

1.1 This guide covers recommended procedures for handling material stored at low temperatures in mechanical freezers and liquid nitrogen freezers. 1.2 This guide covers recommendations for implementing procedures for ensuring adequate inventory control. 1.3 This guide covers recommendations for implementing procedures for safeguarding material stored at low temperatures. 1.4 This guide does not cover the development or maintenance of equipment and facilities for low-temperature storage which are covered in Guide E1564 . 1.5 This guide does not cover practices for preservation by freezing which are covered in Practice E1342 . 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 4.1 The proper handling of material stored at low temperatures ensures that the stability of sensitive biological materials is not comprised. 4.2 Properly designed inventory control systems ensure the maximum use of freezer space, that all material can be located easily, and that any item is retrieved easily without compromising the stability of other items in the freezer. 4.3 Properly designed safety and security procedures ensure that material stored at low temperatures is not comprised during storage, and that if material is lost due to freezer failure or operational problems, replacement material is available (see Guide E1566 ).
