Hazards associated with primary lithium cells
Hazards involved in these process steps include: Material handling of charged lithium-ion cells (conveyors, stacker cranes, automated loading/unloading of trays of cells, removal of gas buildup during the Degas stage, Automated Storage and Retrieval Systems). Charging and discharging of lithium-ion cells.
Configuration of Lithium-Ion Battery Cells: The placement of cells within enclosures or located where suppression systems are obstructed can significantly increase the risk of a fire hazard. In the event of a fire in rack storage, for instance, ceiling-level sprinklers may be ineffective at applying water to the source of the fire.
