Meaning
Packing instruction defined within the International Maritime Dangerous Goods Code for the safe transport of damaged or defective lithium ion batteries. Compliance with LP905 ensures that large batteries which can no longer be tested according to standard protocols are moved without endangering the vessel. This regulation applies specifically to units that are not prone to rapid disassembly or dangerous reactions under normal transport conditions.
Containment Requirement
Physical barriers must prevent the release of flame or fragments in the event of a thermal runaway during transit. The LP905 standard mandates the use of non-combustible and non-conductive thermal insulation as a lining for the outer packaging. These materials absorb the energy released by the battery and maintain the exterior temperature of the container within safe limits.
Using vermiculite or specialized glass fiber blankets provides the necessary protection against high-intensity heat. The pressure relief systems in the outer box must also allow gas to escape while preventing the passage of sparks or large debris. Testing of these containers includes a drop test and a stack test to ensure they maintain their form under heavy loads.
Transport Safety
Mitigation of the risks associated with unstable energy storage devices is the primary goal of the shipping protocol. Because LP905 governs the movement of units that may have internal shorts, the packaging must be leak-proof to prevent the escape of electrolyte. Carriers verify the integrity of the specialized large packaging before the vessel departs the port.
Compliance Documentation
Detailed records identifying the condition of the battery and the specific packaging used must accompany every shipment. While the regulation allows for the transport of high-risk items, the LP905 designation requires approval from the competent national authority in the country of origin. This oversight ensures that the risk assessment performed by the shipper aligns with international safety standards.
