Specific safety concerns include: (1) Lithium batteries pose both a chemical and electrical hazard — under certain conditions they can overheat and ignite and, once ignited, can be especially difficult to extinguish; (2) the potential for propagation of thermal runaway between cells or batteries in a package and between adjacent packages of batteries; (3) the potential for uncontrolled lithium battery fires to overwhelm the capability of existing aircraft cargo fire protection systems, leading to a catastrophic failure of the airframe; and (4) the potential for venting of combustible gases from lithium ion cells in thermal runaway, which could collect in an enclosed environment and cause an explosion even in the presence of a suppression agent.
