Committee of Experts on the Transport of Dangerous Goods and on the Globally Harmonized System of Classification and Labelling of Chemicals

Sub-Committee of Experts on the Transport of Dangerous Goods

Forty-first session

Geneva, 25 June – 4 July 2012
Item 4 (c) of the provisional agenda

Electric storage systems: waste or damaged/defective lithium batteries

New Special Provision and Packing Instruction for Damaged or Defective Lithium Batteries

Transmitted by the Rechargeable Battery Association (PRBA) and the International Association for the Promotion and Management of Portable Rechargeable Batteries (RECHARGE)

Introduction

1. There are no provisions in the Model Regulations for transporting damaged or defective lithium cells and batteries.  This issue was discussed at length during the lunchtime working groups at the thirty-ninth and fortieth sessions of the UN Sub-Committee.  To address this issue, PRBA and RECHARGE are proposing to add a Special Provision and two new Packing Instructions for incorporation into the Model Regulations for transporting damaged or defective lithium cells and batteries. 

2. There were two key issues discussed at the lunchtime working groups during the fortieth session of the Sub-Committee:  defining a damaged or defective lithium cell or battery and establishing the necessary packaging for transporting them.

3. PRBA and RECHARGE's proposed Special Provision YYY provides an example of a damaged or defective cell and battery: “… (e.g., a cell or a battery that has lost a part of its mechanical or electrical integrity (external or internal)) that have the potential of producing a dangerous evolution of heat, fire or short circuit…”  The language is generally consistent with the ICAO Technical Instructions but also adds an example of what may be considered damaged or defective.  In addition, a requirement has been added that cells or batteries be inspected prior to transport for one or more of the following, but not limited to: mechanical integrity, temperature, signs of rupture, venting, disassembly and leakage or open circuit voltage.  After inspection, appropriate steps must be taken to eliminate the potential for a dangerous evolution of heat or fire during transport.

4.  Packing Instructions P9XX and LP9XX also are being proposed for packaging damaged and defective lithium cells and batteries for transport.  They include PG II packaging, a requirement that each cell, battery or equipment be individually packed in an inner packaging inside an outer packaging and surrounded by cushioning material that is non-combustible and non-conductive.  Leaking cells and batteries would require sufficient inert absorbent material to absorb any release of electrolyte.  In addition, cells and batteries must be packaged to prevent excessive movement within the packaging that may lead to venting or rupture during transport.

 Proposal

5. In consideration of the foregoing, PRBA and RECHARGE invite the Sub‑Committee to consider the following proposal for a new Special Provision, Packing Instruction and Large Packing Instruction for the transport of damage or defective lithium batteries.

SP YYY

When offered for transport, lithium ion cells and batteries and lithium metal cells or batteries identified as being defective for safety reasons, or that have been damaged (e.g., a cell or a battery that has lost a part of its mechanical or electrical integrity (external or internal)), that have the potential of producing a dangerous evolution of heat, a fire or a short circuit, shall be packaged in accordance with Packing Instructions P9XX or LP 9XX, as applicable.  Before being packaged and offered for transport, the cells or batteries shall be inspected for one or more of the following, but not limited to: mechanical integrity, temperature, signs of rupture, venting, disassembly and leakage or open circuit voltage.  After inspection, appropriate steps (measures) shall be taken to eliminate the potential for a dangerous evolution of heat or fire during transport.

Package shall be marked with package orientation arrows and “Damaged/Defective Lithium ion Batteries” or “Damaged/Defective Lithium Metal Batteries”, as applicable.

第四十一次会议

日内瓦, 2012年6月25日-7月4日
议程第4（c）项

电存储系统：废旧或损坏/有缺陷的锂电池

损坏的或有缺陷的锂电池的新特殊规定和包装说明

由可充电电池协会(PRBA)和国际便携式可充电电池促进和管理协会(RECHARGE)提交

介绍

1.在规章范本中没有对运输损坏的或有缺陷的锂电池芯和电池的规定。这个问题在39次和40次分委员会会议午餐工作组中讨论了很长时间。为解决这个问题，PRBA和RECHARGE提议在规章范本中增加一个特殊规定和两个新的包装说明用于运输损坏的或有缺陷的锂电池芯和电池。

2. 在40次分委员会会议的午餐工作组中已讨论了两个关键问题：定义损坏的或有缺陷的锂电池芯和电池和建立用于运输这类电池的必要的包装。

3. PRBA和REGAGE 提出特殊规定YYY来提供了一个损坏的或有缺陷的锂电池芯和电池的例子:“…(如，一个损失了其机械或电气完整性一部分（外部或内部）的电池芯或电池有危险性放热、起火或短路的可能…”这段文字基本和ICAO技术细则总体一致，而且增加了一个什么是被认为损坏的或有缺陷的例子。另外，还增加了一个在运输前对电池芯或电池进行如下所述的一项或更多项检查的要求，包括但不限于：结构完整，温度，破裂迹象，排气，解体和泄漏或开路电压。检查后，采取适当的措施消除运输中潜在的危险性放热、起火的可能。

4.包装说装说明P9XX和LP9XX也被提议用于运输损坏的或有缺陷的锂电池芯和电池的包装。包括PGII包装 ，要求每个电池芯、电池或设备都单独包装在内包装中，然后装在外包装中，并填充有不可燃的和不导电的衬垫材料。对泄漏的电池芯和电池要有足够的惰性吸收材料，能完全吸收泄漏的电解液。另外，应采取适当的措施防止包装中可能导致电池芯或电池在运输中短路、排气或破裂的过多移动。

 提议

5.基于上面所述，PRBA和RECHARGE 邀请分委员会考虑下面的提议，主要是用于运输损坏的或有缺陷的锂电池的一个新的特殊规定，包装说明和大包装说明。

 SP YYY 

在交付运输时，有安全缺陷的或损坏的锂离子电池芯和电池、锂金属电池芯或电池（如，一个损失了其机械或电气完整性一部分（外部或内部）的电池芯或电池）有危险性放热、起火或短路的可能，应按其适用性符合包装说明P9XX或LP9XX，在包装和交付运输前，电池芯或电池应进行如下所述的一项或更多项检查，包括但不限于：结构完整，温度，破裂迹象，排气，解体和泄漏或开路电压。检查后，采取适当的措施消除运输中潜在的危险性放热、起火的可能。

包装上应标记包装方向箭头并按使用性标记“损坏的/有缺陷的锂离子电池”或“损坏的/有缺陷的锂金属电池”。
