Pack Safe

Avalanche rescue backpack, self-inflating

These devices typically contain a cylinder of compressed nonflammable gas. Some models also contain a small explosive charge (squib) to release the cylinder contents.

Though allowed in checked baggage by international (ICAO/IATA) regulations, these devices are not allowed in baggage in the U.S. unless the gas cylinder is empty and there is no explosive charge.

Though not restricted as a hazardous material when the gas cylinder is empty and no explosive charge is present, airport security screeners may still want to examine the gas cylinder to ensure it is empty.
