While the new technologies require further testing, "we believe they have the potential to revolutionize cargo safety," UPS spokesman Mike Mangeot said.
Separately, the FedEx Corp. has developed a fire-suppression system that, once a fire is detected in a cargo container, punches a hole into the top of the container and injects an argon-based foam capable of smothering a fire, as well as absorbing toxic fumes, officials for the airline said.
FedEx has installed the system on its Boeing 777s and MD11s, which fly long routes over water and to remote areas of the globe. "We will continue installation on our entire long-haul fleet," FedEx spokeswoman Maury Donahue said.
