Into the next room, a
recently constructed mass
decontamination facility is shown in a partially constructed state,
so that we can see around it, and understand how it works:
The central triage/observation room shown above was built from six large sheets of very dark smoked lexan. The hexagonal shape of this room is comprised of its windows, each of which make up an entire wall. We cannot see into the triage/observation room because it is dark inside the room, but we know that if one or more persons were inside that they could very clearly see out into the six hexagonal rooms that are to be built around it. The locations where the walls of these six hexagonal rooms are to be built are marked in red tape:
Here we see, for example, the entrance to women's stripdown and bagging room showing, in yellow tape, where the rotors of a RotoGate high security seven foot high turnstile will go.
Separate entrances for men and women are to be provided. Three of the six rooms are for men, and the other three are for women.
The shiny tape on the hardwood floor, and the choice of colors (red and yellow) is also reminiscent of the markings on a gymnasium floor (thus calling to mind the inevitable communal stripdown and shower experience to follow).
A column shower is to be installed in each of the two shower rooms.
A Bradley six station
column shower has already been installed in the men's washdown room:

The knobs and soap dishes have been removed from the column shower,
and the holes where these items once were have been replaced with a
machine vision system comprised of 12 laser diode body scanners together
with six round lexan viewing windows moulded into the inside of the
column. There are two laser diode body scanners for each of the
video sensors that are located at each of the six stations,
for purposes of photometric stereo imaging of the bodies
of the users of the column shower.
A set of six video motion detectors with
an Internet connected machine vision computer is to be placed inside each
of the two column showers in the men's and women's washdown rooms.
The system is sealed and completely watertight. Here is a closeup
picture of the six round watertight
viewports of the column shower currently in use in the men's washdown room:
Three of the round smoked lexan viewing windows are visible here. Up to six men can use this shower at the same time, but only the number of stations actually being occupied will consume water. Moreover, water is only consumed when a user is present. Since there are no knobs or controls of any kind, there is no possibility for deliberately destructive acts such as might otherwise happen when users deliberately (or accidentally) leave the water running. Each of the six nozzles face one side of the hexagonal shaped room to maximize space usage and efficiency.
One of the six walls in this room is made entirely of smoked lexan, so that triage personnel or decontamination officers can supervise the decontamination process, whereas the six or fewer men in this room cannot see the triage personnel or decontamination officers, because of the darkness of the lexan (transmissivity is approximately 10 percent, meaning that transmissivity squared is approximately 1 percent, as compared to roughly four percent reflectivity of the surface, such that any visual perception of triage personnel or decontamination officers will fall below a noise floor).
Typically, however, the triage personnel or decontamination officers
operate the facility remotely by way of six video cameras installed in the
triage/observation room. These six cameras are connected to six
television receivers at a remote location, as shown below:
The six television receivers are arranged in the same hexagonal formation.
Six closed circuit television receivers suspended from the ceiling display outputs from each of the six decontamination rooms, as observed from the triage room.
The four of the six screens that are visible here correspond to (from left to right) the:
Although the television displays shown here are of poor resolution:
(Here is the view from the men's decontamination/triage officer station, during a Decon Drill, held at the 80 Spadina Ave. facility, Thursday July 5th, 2001.)
The cameras are of very high quality and high resolution, so that remote triage personnel can clearly distinguish, for example, anthrax, from dust or other dirt. Archived images can also be used as evidence to prosecute those placing society at risk by failing to properly undergo decontamination.
Thus high resolution sensors are to be used throughout the facility to
ensure satisfactory video quality:
The above images illustrate the: (1) Strip; (2) Wash; and (3) Cover procedure.
These three steps were practiced in the 2001 July 5th decon drill:

The exhibit features the world's first true wearable computer, along with other wearable computers from the last twenty years, together with the mass decontamination facility that includes the most modern Internet connected sensor operated showers with photometric stereo body-scanning machine vision capability.
