PHMSA–2006–25446 (HM–243): Hazardous Materials: Fuel Cell Cartridges and Systems Transported on Board Passenger Aircraft in Carry- On Baggage; Effective Date 10/1/2008

SUMMARY: PHMSA is amending the Hazardous Materials Regulations (HMR) to permit certain fuel cell cartridges and fuel cell systems designed for portable electronic devices to be transported by passengers and crew in carry-on baggage on board passenger-carrying aircraft. Fuel cell cartridges and fuel cell systems are an emerging energy technology developed to provide a more efficient, longer-lasting, and renewable power source for electrically operated equipment. This final rule prescribes regulations for transporting fuel cells containing flammable liquids, including methanol; formic acid; certain borohydride materials; or butane that meet certain performance and consumer use standards. PHMSA is issuing this final rule in cooperation with the Federal Aviation Administration (FAA).
