One pack of safety matches, a BIC or a ZIPPO lighter, is allowed when carried on or in carry-on baggage. On the other hand lighter fuel, lighter refills and lighters containing unabsorbed liquid fuel, are not, as it has been and continues to be the case under the 49 CFR, Pipeline and Hazardous Materials Safety Administration in 175.10(a)(2) Exceptions for passengers, crewmembers, and air operators.
What’s new is lithium battery powered laser plasma lighters, tesla coil lighters, flux lighters, single and double arc lighters, will now be required to meet UN Testing and Criteria recommendations. In addition, these lighters must be equipped with a means to prevent unintentional activation of the heating element and passengers and crew should be aware the recharging of these devices on board the aircraft is not permitted.
Each battery's lithium content must not exceed 2 grams for lithium metal batteries, and for lithium ion batteries, a Watt- hour (Wh) rating of 100 Wh. All per the May 11, 2020 PHMSA final rule amending the domestic Hazardous Materials Regulations (HMR) to maintain alignment with international regulations and standards.
