Fire-fighting foam

摘要

Fires started by faulty lithium batteries are a major concern for air freight haulers such as Federal Express. The expediter has teamed up with Ventura Aerospace to develop an electronics system that smothers fires with foam that lasts up to four hours.rnThe two companies collaborated on a system that monitors individual cargo containers. Its dedicated modules watch individual containers for potential fires and then fill them with retardants. "The system monitors temperature. When it gets beyond a certain level, it will punch a 2.5-in hole in the container and inject foam," said Bruce Popp, Strategic Products Manager, Federal Express.
