E4 Cryoberth Chamber Fixtures and Equipment

Page history last edited by Michael 2 years, 2 months ago

back to Engineer Team E-4 or the E-4 bunker, the E-4 Team Equipment, or the Index


floor heaters and personal equipment are seen lying on the floor in this image


     See also the bunker description. The chamber where the teams spends years in cryogenic suspension is 9 meters wide and 15 meters long (1453 square feet, if it matters), with a high, arched ceiling. There are nine pads for cryoberths in the bunker, but only eight cryoberths.

     The walls and ceiling are covered in white polyethylene sheeting; there are thirteen clusters of stainless-steel air nozzles protruding from the walls -- these will be cold and covered with a small amount of frost when the team wakes up. A pressure relief valve is built into the wall near each door.

     Six 500-watt incandescent bulbs hang from the ceiling, with cone-shaped metal shades; the ceiling space is thus sort of dim. Several standard 110-volt AC power outlets are set low along the walls; each has an electro-luminescent night-light plugged into it; the cryoberths are plugged into their own heavy-duty 240 volt outlets.




     Four 1,500 watt electric convection heaters are also plugged into the 110 volt outlets. Each is 5.6 kg, 45 cm tall, 22 liters volume, with a 4 meter long power cord.

     The "outer" end of the chamber has the bunker "monitor computer and VLF radio" on a shelf.

     There are four 5-gallon white plastic buckets filled with bentonite dessicant, scattered about the chamber. The screw-on lids for these buckets are stacked neatly along one side of the chamber.

     In the middle of the chamber is a folding banquet table, with eight candy bars and eight cans of water. The team's basic loads and role kits are piled neatly on the floor at the foot of each cryoberth; their personal effects boxes are stored inside the cryoberths, protected by the heavy lids.

     Set in the floor under the folding table is a small, perforated metal plate -- it covers a sump about a meter deep. The sump, in turn, connects to several "leach line" pipes buried in the cinders; there's a backflow-preventer valve at the bottom of the sump. Stenciled on the floor next to the metal plate are the words, "NOT SANITARY DRAIN."

     There's a big "flight line" type of fire extinguisher in the chamber (see the Other Supplies section for more details on this).


Janitorial Cabinet


     A 2-meter tall metal four-door cabinet against the wall, near the exit to the main tunnel; it holds "janitor supplies":


  • 2 gray plastic "bus trays" (sort of like what restaurants use for clearing tables)

  • 2 stiff-bristle push brooms

  • 2 big dustpans

  • a mop and rolling mop bucket/mangle

  • box of 6 replacement mop heads

  • 5 bags (23 kg each) of bentonite (mostly for use as oil and spill absorbent in this case)

  • 8 body bags

  • 2 snow shovels

  • 2 cardboard boxes, each with 24 incandescent light bulbs (500 watt rating)

  • wet/dry utility vacuum cleaner; mass 15 kg, includes two 3 meter hoses and a 6 meter power cord; runs on 110 volt AC power

  • 20 liter white plastic bucket of concentrated cleaner/degreaser (main active ingredient caustic soda, aka sodium hydroxide at pH 12:  "Do not breathe fumes or spray; wash face, hands and any exposed skin thoroughly after handling; wear protective gloves, clothing and eye protection during use." Much less concentrated than drain cleaner, but it will strip paint; do not use on aluminum surfaces.)

  • cardboard box of 40 pairs of blue rubber disposable gloves

  • cardboard box of 40 pairs of blue rubber drawstring boot covers

  • cardboard box of 20 SCALP sets ("suit, contamination avoidance, liquid protective"): polyethylene hooded jacket, trousers, and booties in sage green. Sizes are two S, four M, four L, six XL and four XXL (although the sizes are all oversize to allow wearing over AUIB suits and other clothing). They are not intended to be re-used, cleaned or laundered, and in fact are usually "torn off" after about an hour's wear in the field. Each suit comes in a sealed OD green plastic bag, about 21 cm long, 15 cm wide and otherwise "bulgy"; bagged suit weighs 0.6 kg.

  • 10 cans of Boraxo

  • 2 cases of shop towels (30 rolls per case, 55 heavy-duty blue paper towels per roll)

  • 25 kg bale of wiping rags

  • stack of 6 plastic garbage cans, 32 gallon capacity, with six snap-on lids

  • case (roll) of 100 contractor's 33 gallon black plastic trash bags, 2.5 mil thickness

  • 4-wheel dolly for garbage cans (and other items)
