Abstract
Work crews temporarily operating in remote areas can be subject to dangers such as tornadoes, hurricanes and explosive blast waves. A re-deployable aboveground protective shelter suitable for use in such environments utilizes retractable stabilizing arms and/or passive valved ductwork to resist uplift, overturning and sliding. Because the protective shelter does not rely upon excessive weight to counter wind forces, the protective shelter can be quickly, easily and inexpensively redeployed to new sites.
