PackSafe - Battery Powered Heat Producing Devices

Diving lamps, soldering equipment

Quantity limits: None

Requires airline approval.

Many battery-operated devices such as lamps/lights used in scuba diving and soldering tools can produce intense heat capable of starting a fire if the device is accidentally activated. These are allowed in checked and carry-on baggage, with airline approval, when a component (battery, fuse, heat element) is isolated to prevent unintentional activation and generation of heat during transport.

If the battery has been completely removed then the device is not restricted as a hazardous material. However, if carrying the battery separately, it must be carried in accordance with the provisions for spare batteries in the PackSafe chart. Each installed or spare lithium battery must not exceed 2 grams of lithium content for a lithium metal battery or 100 Wh for a lithium ion battery.

See the regulation: 49 CFR 175.10(a)(14)
