Decontamination enclosure and method
View Patent ↗Provided are a method and apparatus for decontaminating personal protective equipment while it is being worn by a person. A booth having a plurality of internally-reflective surfaces defines an interior space with dimensions suitable for receiving a standing person wearing the personal protective equipment. A plurality of UVC light sources are arranged to emit UVC light into the booth, and are operational while the person wearing the personal protective equipment is within the interior space. A door is selectively closeable to enclose the interior space and interfere with UVC light escaping the interior of the booth into an ambient environment of the booth, and a controller is operable to selectively operate the UVC light sources while the person wearing the personal protective equipment is standing within the interior space.
1. A decontamination apparatus comprising:
a booth having a plurality of internally-reflective surfaces that define an interior space having dimensions suitable for receiving a standing person wearing personal protective equipment;
a plurality of UVC light sources arranged to emit UVC light into the booth;
a door that is selectively closeable to enclose the interior space and interfere with UVC light escaping the interior of the booth into an ambient environment of the booth; and
a controller operable to selectively operate the UVC light sources while the person wearing the personal protective equipment is standing within the interior space, wherein the controller is accessible to, and operable by the person wearing the personal protective equipment from within the interior space to allow the person to control operation of the UVC light sources from within the interior space.
2. The decontamination apparatus of claim 1 , wherein the controller comprises a timer operational to initiate deactivation of the UVC light sources after expiration of a predetermined period of time.
3. The decontamination apparatus of claim 2 , wherein the predetermined period of time is selectable from a plurality of pre-programmed time periods stored by the controller.
4. The decontamination apparatus of claim 1 further comprising a vent provided to at least one side wall defining the interior space to allow an exchange of air between the interior space and the ambient environment.
5. The decontamination apparatus of claim 1 , wherein the plurality of the UVC light sources are each coupled to an adjustable arm to render the UVC light sources adjustable relative to the interior space of the booth.
6. A decontamination apparatus comprising:
a booth having a plurality of internally-reflective surfaces that define an interior space having dimensions suitable for receiving a standing person wearing personal protective equipment;
a plurality of UVC light sources arranged to emit UVC light into the booth;
a door that is selectively closeable to enclose the interior space and interfere with UVC light escaping the interior of the booth into an ambient environment of the booth; and
a controller operable to selectively operate the UVC light sources while the person wearing the personal protective equipment is standing within the interior space,
wherein the plurality of the UVC light sources are adjustable by the person from within the interior space while the UVC light sources are operational.
7. The decontamination apparatus of claim 6 , wherein the plurality of the UVC light sources are each coupled to an adjustable arm to render the UVC light sources adjustable relative to the interior space of the booth.
8. The decontamination apparatus of claim 6 , wherein the controller comprises a timer operational to initiate deactivation of the UVC light sources after expiration of a predetermined period of time.
9. The decontamination apparatus of claim 8 , wherein the predetermined period of time is selectable from a plurality of pre-programmed time periods stored by the controller.
10. The decontamination apparatus of claim 6 further comprising a vent provided to at least one side wall defining the interior space to allow an exchange of air between the interior space and the ambient environment.
11. A decontamination apparatus further comprising:
a booth having a plurality of internally-reflective surfaces that define an interior space having dimensions suitable for receiving an object;
a plurality of UVC light sources arranged to emit UVC light into the booth;
a door that is selectively closeable to enclose the interior space and interfere with UVC light escaping the interior of the booth into an ambient environment of the booth;
a controller operable to selectively operate the UVC light sources while the object is within the interior space; and
a platform comprising a surface that is substantially transparent to UVC light on which the object may be located to allow a bottom surface of the object to be exposed to the UVC light emitted by at least one of the UVC light sources.
12. The decontamination apparatus of claim 11 wherein the object includes at least one of personal protective equipment worn by a person, a wheelchair, or any other inanimate object.
13. A decontamination apparatus comprising:
a booth having a plurality of internally-reflective surfaces that define an interior space having dimensions suitable for receiving an object;
a plurality of UVC light sources arranged to emit UVC light into the booth;
a door that is selectively closeable to enclose the interior space and interfere with UVC light escaping the interior of the booth into an ambient environment of the booth;
a controller operable to selectively operate the UVC light sources while the object is within the interior space; and
a window provided to at least one side wall defining the interior space, the window being closed by a flexible material that is substantially transparent to visible light, but interferes with transmission of UVC light from the interior space to the ambient environment.
14. The decontamination apparatus of claim 13 wherein the object includes at least one of personal protective equipment worn by a person, a wheelchair, or any other inanimate object.
15. A decontamination apparatus comprising:
a booth having a rigid frame that supports a shell, the shell including a plurality of internally-reflective surfaces that define an interior space having dimensions suitable for receiving an object;
a plurality of UVC light sources arranged to emit UVC light into the interior space;
a door that is selectively closeable to enclose the interior space and interfere with UVC light escaping the interior of the booth into an ambient environment of the booth; and
a controller operable to selectively operate the UVC light sources while the object is within the interior space.
16. The decontamination apparatus of claim 15 wherein the rigid frame includes a plurality of interlocking segments.
17. The decontamination apparatus of claim 16 wherein the plurality of interlocking segments are configured to be assembled end to end by hand.
18. The decontamination apparatus of claim 16 wherein the plurality of interlocking segments are configured to be pulled apart and arranged to fit into a portable container to be carried by hand during relocation of the decontamination apparatus.
19. The decontamination apparatus of claim 15 wherein the shell includes at least one of a woven fabric or a cross-woven ballistic nylon.
20. The decontamination apparatus of claim 15 wherein the plurality of internally-reflective surfaces of the shell include an aluminized material configured to reflect the UVC light emitted by the plurality of UVC light sources.
