Decontamination shelters with integrated ballast systems

摘要

Ballast systems for, particularly, inflatable decontamination shelters are described. The systems may be integrated into the overall structures of the shelters so as to avoid need for sand bags or other discrete weight-providing objects. They additionally may use liquids (rather than or in addition to solids) for weight-providing purposes, with the liquids including water supplied by the same plumbing system that supplies a shower of a shelter.

主权项

1. A decontamination shelter comprising:
a. an inflatable structure for at least partially isolating a human from his or her environment and comprising (i) at least two ballast tubes, each comprising a chamber and extending substantially parallel with the other, (ii) at least two cross tubes, each comprising a chamber and extending substantially perpendicular to the at least two ballast tubes, (iii) at least one inflatable support tube to which at least one ballast tube is connected, and (iv) a shower, wherein the at least two ballast tubes each comprise either a height or a width greater than a respective height or width of each of the at least two cross tubes, and the chambers of each of the at least two ballast tubes are in communication with one another to allow liquid to travel within each chamber; b. a liquid source communicating with (i) the at least two ballast tubes to supply ballast liquid thereto and (ii) the shower to supply shower liquid thereto; c. ballast plumbing configured to communicate the ballast liquid from the liquid source to the at least two ballast tubes; d. shower plumbing configured to communicate the shower liquid from the liquid source to the shower; e. a control valve (i) interposed between the liquid source and each of the shower plumbing and the ballast plumbing and (ii) configured to supply both ballast liquid and shower liquid concurrently from the same source; and f. a pressure regulator (i) interposed between the control valve and at least one ballast tube and (ii) configured to reduce pressure of the ballast liquid below pressure of the shower liquid.
