The pressure relief panel guard of claim 1 wherein the perimeter wall includes opposing first and second elongated side members, and third and fourth elongated opposing side members, with the third and fourth side members being shorter in length than the first and second side members. 4. The pressure relief panel guard of claim 3 wherein each of the first, second, third and fourth side members has an inward facing wall portion and an outward facing wall portion, and first and second end portions, with the first side member extending between the first end portions of the third and fourth side members, having the first end portion of the first side member rigidly connected to the first end portion of the third side member and forming a first corner portion of the perimeter wall, and the second end portion of the first side member rigidly connected to the first end portion of the fourth side member and forming a second corner portion of the perimeter wall, and having the second side member spaced apart from the first side member and extending between the second end portions of the third and fourth side members, having the first end portion of the second side member rigidly connected to the second end portion of the third side member and forming a third corner portion of the perimeter wall, and the second end portion of the second side member rigidly connected to the second end portion of the fourth side member and forming a fourth corner portion of the perimeter wall. 5. The pressure relief panel guard of claim 4 wherein each of the first, second, third and fourth corner portions is convexly rounded. 6. The pressure relief panel guard of claim 5 wherein the first, second, third and fourth side members each project downward and terminate at a lower edge portion and together define a generally rectangular perimeter ridge with convexly rounded corner ridge portions. 7. The pressure relief panel guard of claim 4 wherein the first, second, third and fourth side members each project downward and terminate at a lower edge portion and together define a generally rectangular perimeter ridge. 8. The pressure relief panel guard of claim 7 wherein each of the outwardly facing wall portions of the first, second, third and fourth side members is beveled with a slope extending upward and outward from a corresponding one of the lower edge portions of the perimeter ridge. 9. The pressure relief panel guard of claim 1 wherein the perimeter wall includes opposing first and second side members, and third and fourth opposing side members, and further a net spanning between the first, second, third and fourth side members such that when supported by the guard support portion of the mounting structure at the pressure relief ceiling panel the net is spaced downwardly away from the relief ceiling panel. 10. The pressure relief panel guard of claim 9 wherein the net is releasably attached to at least the third and fourth side members. 11. The pressure relief panel guard of claim 1 wherein the perimeter wall includes opposing first and second side members, and third and fourth opposing side members, each having a lip portion projecting laterally outward and located adjacent to the cargo bay ceiling when the guard structure is supported by the guard support portion of the mounting structure at the pressure relief ceiling panel. 12. The pressure relief panel guard of claim 1 wherein the perimeter wall includes at least two opposing connector portions, and the guard support portion of the mounting structure includes a pair of elongated channel portions, each with a laterally facing opening extending the length of the channel portion and having an end opening, each configured to slidably receive one of the opposing connector portions of the perimeter wall therein. 13. A pressure relief panel guard for use with a pressure relief ceiling panel having a perimeter and positioned in an aircraft cargo bay ceiling, comprising: a guard structure attachable to the cargo bay ceiling, the guard structure having a perimeter wall and a central opening between the perimeter wall sized such that when the guard structure is attached to the cargo bay ceiling at the pressure relief ceiling panel the perimeter wall does not overlap the pressure relief ceiling panel or otherwise restrict operational access to the pressure relief ceiling panel from below, the perimeter wall projecting downward away from the aircraft cargo bay ceiling and terminating below the pressure relief ceiling panel. 14. The pressure relief panel guard of claim 13 wherein the perimeter wall projects downward at least 2 inches. 15. The pressure relief panel guard of claim 13 wherein the guard structure is configured for releasable attachment to the cargo bay ceiling. 16. The pressure relief panel guard of claim 13 wherein the perimeter wall includes opposing first and second elongated side members, and third and fourth elongated opposing side members, each of the first, second, third and fourth side members has an inward facing wall portion and an outward facing wall portion, and first and second end portions, with the first side member extending between the first end portions of the third and fourth side members, having the first end portion of the first side member rigidly connected to the first end portion of the third side member and forming a first corner portion of the perimeter wall, and the second end portion of the first side member rigidly connected to the first end portion of the fourth side member and forming a second corner portion of the perimeter wall, and having the second side member spaced apart from the first side member and extending between the second end portions of the third and fourth side members, having the first end portion of the second side member rigidly connected to the second end portion of the third side member and forming a third corner portion of the perimeter wall, and the second end portion of the second side member rigidly connected to the second end portion of the fourth side member and forming a fourth corner portion of the perimeter wall. 17.
