Abstract
A portable safety vest (20) includes an inflatable collar (22) which functions as a personal floatation device, a transparent, inflatable air bag (50), and an air mask (60). A cylinder of compressed air (40) has a seal (41) and, when the seal (41) is broken by a triggering mechanism (42, 43, 44), the compressed air expands and fills the air bag (50) and the collar (22). The air bag (50) is preferably large enough to hold at least a two-minute supply of air to allow one time to escape from an area filled with smoke or noxious or toxic gas.
