Incident ReportingIncident Reporting
• FAA maintains record of reported battery incidents
• Final rule on lithium batteries did not eliminate exemption
• Unlikely that FAA record provides accurate account

Analysis of Specific RisksAnalysis of Specific Risks
• Secondary batteries– Failure modes not well understood– Proper evaluation not always performed– Failed batteries prematurely disposed
• Primary batteries– Impact of clustering not yet considered

Remaining ExemptionsRemaining Exemptions
• Small secondary batteries – Exempt from packaging and identification
requirements– Cargo shipments permitted on cargo and
passenger flights

Involvement in In-Flight FiresInvolvement in In-Flight Fires
• Halon is effective in suppressing secondary battery fires– Suppression systems not yet required
• Halon is not effective in suppressing primary battery fires– Additional safety measures needed
