The portable containment structure of claim 1 wherein the wheel retractors further comprise a plurality of hydraulic jacks spaced around the perimeter of the support frame and disposed vertically so as to alternatively be raisable and lowerable between (i) a retracted position wherein a lowermost portion of each jack is disposed proximate to the support frame, and (ii) an extended position wherein the lowermost portion of each jack is disposed spaced apart below the support frame. 3. The portable containment structure of claim 2 wherein each of the plurality of hydraulic jacks is operable independently of the other hydraulic jacks. 4. A portable containment structure comprising: (a) a support frame having an upper side, a lower side and a perimeter, the perimeter defining a central opening;(b) an enclosed containment compartment attached to the upper side of the support frame, the containment compartment having a bottom opening which is in communication with the central opening in the support frame;(c) at least four wheels attached to the support frame, the wheels being operatively adapted to facilitate lateral movement of the support frame across a surface; and(d) wheel retractors for retracting each of the wheels upwardly with respect to the support frame such that the support frame is raisable and lowerable between (i) a raised position wherein the support frame is disposed at a first elevation and can be laterally moved along a surface using the attached wheels, and (ii) a lowered position wherein the support frame is disposed at a second elevation which is lower than the first elevation and wherein the frame is disposed in contact with the surface, each wheel retractor comprising a retractable plate attached at one end to the hub of a wheel and pivotally attached at an opposite end to the support frame, such that each wheel can alternatively be rotated between (i) a first position wherein the support frame is disposed in the raised position, and (ii) a second position wherein the support frame is allowed to assume the lowered position, the wheel retractors further comprising a plurality of hydraulic jacks spaced around the perimeter of the support frame and disposed vertically so as to alternatively be raisable and lowerable between (i) a retracted position wherein a lowermost portion of each jack is disposed proximate to the support frame, and (ii) an extended position wherein the lowermost portion of each jack is disposed spaced apart below the support frame, each of the plurality of hydraulic jacks being operable independently of the other hydraulic jacks. 5. The portable containment structure of claim 4 wherein each of the plurality of hydraulic jacks is operable independently of the other hydraulic jacks. 6. A portable containment structure comprising: (a) a support frame having an upper side, a lower side and a perimeter, the perimeter defining a central opening;(b) an enclosed containment compartment made of steel of such strength and thickness to withstand the inadvertent explosion of ordinance being handled within the containment compartment, the containment compartment being attached to the upper side of the support frame, the containment compartment having a bottom opening which is in communication with the central opening in the support frame;(c) at least four wheels attached to the support frame, the wheels being operatively adapted to facilitate lateral movement of the support frame across a surface;(d) wheel retractors for retracting each of the wheels upwardly with respect to the support frame such that the support frame is raisable and lowerable between (i) a raised position wherein the support frame is disposed at a first elevation and can be laterally moved along a surface using the attached wheels, and (ii) a lowered position wherein the support frame is disposed at a second elevation which is lower than the first elevation and wherein the support frame is disposed in contact with the surface, each wheel retractor comprising a retractable plate attached at one end to the hub of a wheel and pivotally attached at an opposite end to the support frame, such that each wheel can alternatively be rotated between (i) a first position wherein the support frame is disposed in the raised position, and (ii) a second position wherein the support frame is allowed to assume the lowered position, the wheel retractors further comprising a plurality of hydraulic jacks spaced around the perimeter of the support frame and disposed vertically so as to alternatively be raisable and lowerable between (i) a retracted position wherein a lowermost portion of each jack is disposed proximate to the support frame, and (ii) an extended position wherein the lowermost portion of each jack is disposed spaced apart below the support frame, each of the plurality of hydraulic jacks being operable independently of the other hydraulic jacks. 7. A portable containment structure comprising: (a) a support frame having an upper side, a lower side and a perimeter, the perimeter defining a central opening;(b) an enclosed containment compartment attached to the upper side of the support frame, the containment compartment having a bottom opening which is in communication with the central opening in the support frame;(c) at least three wheels attached to the support frame, the wheels being operatively adapted to facilitate lateral movement of the support frame across a surface; and(d) means for retracting each of the wheels upwardly with respect to the support frame and for alternatively raising and lowering the support frame between (i) a raised position wherein the support frame is disposed at a first elevation and can be laterally moved along a surface using the attached wheels, and (ii) a lowered position wherein the support frame is disposed at a second elevation which is lower than the first elevation and wherein the support frame is disposed in contact with the surface. 8.
