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 removed to prevent accidental activation and generation of heat.
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 packaged and protected from damage and short circuit. See the separate entries for batteries in this table.
See the regulation: 49 CFR 175.10(a)(14)
