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.

1. A protective shelter, comprising: an enclosure having an opening for ingress and egress, a sidewall, a roof, a floor coupled to the sidewall, and at least one support that elevates the floor from a substrate;a peripheral skirt extending toward the substrate to form a substantially enclosed sub-floor region bounded by the peripheral skirt and the floor;a plurality of air ducts communicating between the substantially enclosed sub-floor region and an exterior region of the enclosure, wherein each of the plurality of air ducts houses a valve that permits airflow from the substantially enclosed sub-floor region to the exterior region and resists airflow from the exterior region to the substantially enclosed sub-floor region; anda stabilizer coupled to the enclosure, wherein the stabilizer is horizontally extendable from the sidewall of the enclosure to brace the enclosure against the substrate about the protective shelter in an extended position and is further retractable from the extended position. 2. The protective shelter of claim 1, wherein the enclosure comprises welded metal plate. 3. The protective shelter of claim 1, wherein: the at least one sidewall comprises at least a longer sidewall and a shorter sidewall; andthe protective shelter further comprises a cable attachment point disposed adjacent the shorter sidewall to facilitate loading and unloading the protective shelter from a roll-off container transport. 4. The protective shelter of claim 1, wherein the peripheral skirt includes: a rigid skirt formed of metal plate; anda semi-rigid skirt extending toward the substrate from the rigid skirt. 5. The protective shelter of claim 1, wherein the roof has at least one edge region having a decreasing height at points further from a central axis of the enclosure. 6. An assembly, comprising: a protective shelter in accordance with claim 1; anda roll-off container transport bearing the protective shelter. 7. A protective shelter, comprising: an enclosure having at least a floor, at least one sidewall coupled to the floor, and a roof coupled to the at least one sidewall;at least one support to elevate the floor from a substrate;a peripheral skirt extending toward the substrate to form a substantially enclosed sub-floor region bounded by the peripheral skirt, the substrate and the floor; andone or more air ducts communicating between the substantially enclosed sub-floor region and an exterior region of the enclosure, wherein each of the plurality of air ducts houses a valve that permits airflow from the substantially enclosed sub-floor region to the exterior region and resists airflow from the exterior region to the substantially enclosed sub-floor region. 8. The protective shelter of claim 7, wherein the enclosure comprises welded metal plate. 9. The protective shelter of claim 7, wherein: the at least one sidewall comprises at least a longer sidewall and a shorter sidewall; andthe protective shelter further comprises a cable attachment point disposed adjacent the shorter sidewall to facilitate loading and unloading the protective shelter from a roll-off container transport. 10. The protective shelter of claim 7, wherein the peripheral skirt includes: a rigid skirt formed of metal plate; anda semi-rigid skirt extending toward the substrate from the rigid skirt. 11. The protective shelter of claim 7, and further comprising: at least one stabilizer, coupled to the enclosure, wherein the at least one stabilizer is horizontally extendable from the enclosure to contact a substrate in an extended position and retractable from the extended position. 12. The protective shelter of claim 7, wherein the roof has at least one edge region having a decreasing height at points further from a central axis of the enclosure. 13. An assembly, comprising: a protective shelter in accordance with claim 7; anda roll-off container transport bearing the protective shelter. 14. A protective shelter, comprising: an enclosure formed of welded metal plate, the enclosure having at least a floor, at least one sidewall coupled to the floor, and a roof coupled to the at least one sidewall;at least one support to elevate the floor from a substrate;a peripheral skirt extending toward the substrate to form a substantially enclosed sub-floor region bounded by the peripheral skirt, the substrate and the floor;a plurality of air ducts communicating between the substantially enclosed sub-floor region and an exterior region of the enclosure, wherein each of the plurality of air ducts houses a valve that permits airflow from the substantially enclosed sub-floor region to the exterior region and resists airflow from the exterior region to the substantially enclosed sub-floor region; andat least one stabilizer, coupled to the enclosure, wherein the at least one stabilizer is horizontally extendable from the enclosure to contact a substrate in an extended position and retractable from the extended position. 15. The protective shelter of claim 14, wherein: the at least one sidewall comprises at least a longer sidewall and a shorter sidewall; andthe protective shelter further comprises a cable attachment point disposed adjacent the shorter sidewall to facilitate loading and unloading the protective shelter from a roll-off container transport. 16. The protective shelter of claim 14, wherein the peripheral skirt includes: a rigid skirt formed of metal plate; anda semi-rigid skirt extending toward the substrate from the rigid skirt. 17. The protective shelter of claim 14, wherein the roof has at least one edge region having a decreasing height at points further from a central axis of the enclosure. 18. An assembly, comprising: a protective shelter in accordance with claim 14; anda roll-off container transport bearing the protective shelter. 19. A method of deploying a protective shelter, said method comprising: transporting, to an installation site having a substrate, a protective shelter including: an enclosure having at least a floor, at least one sidewall coupled to the floor, and a roof coupled to the at least one sidewall;at least support to elevate the floor from the substrate;one or more valved air ducts communicating between a region below the floor and an exterior region of the enclosure, anda peripheral skirt extending below the floor; andplacing the protective shelter on the substrate such that the peripheral skirt forms a substantially enclosed sub-floor region bounded by the peripheral skirt, the substrate and the floor. 20. The method of claim 19, wherein transporting the protective shelter comprises transporting the protective shelter on a roll-off transport. 21. The method of claim 19, wherein: the protective shelter further includes at least one retractable and extendable stabilizer;the method further comprises extending from the protective shelter the at least one stabilizer in at least a horizontal direction, such that the at least one stabilizer contacts the substrate in an extended position. 22. The method of claim 21, and further comprising anchoring the at least one stabilizer to the substrate in the extended position. 23. The method of claim 22, wherein the anchoring comprises anchoring the at least one stabilizer utilizing an earth anchor. 24. The method of claim 22, and further comprising: field proving installation of the protective shelter to withstand a rated wind speed by attempting to overcome the anchoring of the at least one stabilizer to the substrate by applying at least a predetermined force to the at least one stabilizer. 25. The protective shelter of claim 1, wherein: the stabilizer has a proximal end and a distal end;the distal end has a contact pad; andin the extended position, a closest point of contact of the contact pad to the substrate is spaced from the sidewall. 26. The protective shelter of claim 1, wherein: the stabilizer has a proximal end and a distal end;the stabilizer has a retracted position in which the distal end has an elevation greater than the total height of the sidewall. 27. The protective shelter of claim 26, wherein the elevation of the stabilizer in the retracted position is sized such that the protective shelter, when loaded for transport, remains within a maximum unpermitted height for roadway transport. 28. The protective shelter of claim 1, wherein the stabilizer, when in the extended position, extends substantially orthogonally from the sidewall. 29.
