FAA is warning air carriers that fire suppressants typically found in cargo compartments are proving ineffective in extinguishing lithium-metal battery (non-rechargeable) fires and are not foolproof in fires involving lithium-ion (rechargeable) fires.
The agency has issued a Safety Alert for Operators (SAFO) recommending that carriers require customers to identify shipments of lithium batteries and to implement special handling and training procedures when they are shipped.
