Work crews temporarily operating in remote areas can be subject to dangers such as tornados, hurricanes and explosive blast waves. A re-deployable mobile aboveground protective shelter suitable for use in such environments utilizes retractable stabilizing arms and/or structures that leverage air pressure differential to resist uplift, overturning and sliding. Because the protective shelter does not rely exclusively upon excessive weight to counter wind forces, the protective shelter can be quickly, easily and inexpensively redeployed to new sites. |
