Part VII DECCNT.MINATICN
The decontamination pad used during Operation C.STLE wag specially
build by Holnes asd Barver contactors in accordance with drawing FS-1196
included as inclosure.
The pad was conrtructed for drainnge toward a 24
inch ceteb basin with ao cast iron mesh cover in tho center of the pad.
4n 8 inch drainnge pipe with a BU% fall drained into the ligoon.
The
119 foot center asaction was constructed of ten (10) inch conerste with 4
inch steel reenforcing.
The two outer soctions, ind the nose section
was constructed of six (6) inch concrete.
Concrate wos pourcd on lternate 20 foot slabs with keyed joints.
The finish was smoothed to p-rnit
easy waah down.
Following the first shot, a 4 inch steel cable was suspended between
the two telephone poles 270 feet apart to provide a safety facility for ser-
sornel during decontamination operations. Six (6) safety rings and cable
assenblies wers attached to tha suspension cable, These wera hooked to
safcty harneeses worn by decontanination personnel,
The cable prevented
serious accidents resulting from falls fron upper wing surfaces during
B-36 decontaniration.
(FS 1451)
Two (2) 1590 watt floodsiphts were placed on cach telephone polo in
order to provide euffictent illumination for decontamination operations
at night.
Recomnendations fer {morovenent in the destgn of the d2contaoiration
pad based upon experience gained during operatica C STLS ure cs follows:
1.
The decontamimtion ped should be 26° fet squaro, so thot atreraft
pay be placed with engines faced into tho wevniling wind prior to deconta=
nination, Uncer the existing conditions duving "C.STLE”" it was virtually
irmossible to decontaminate both vort and starbo:rd sides of B-~36 oircraft
nt the seme tine sicce excessive apray woe blown izto tha dowawind crew.
2. -The entire pad should be of reenfored concrete no luss than 6 inches
thick or of a thichness sufficient to support the weight of aircraft to be
decontaminnted,
3.
Water outlets one (1) inch eize should be vrovided around the pod
oO nininun of twa (2) to exch side, under 450 lbs pressure.
:
It is highly
desirable that a portable water heater be availnble at eich cutlet in order
that o minircrum of tino be expend:d in hoating water.
4,
Urderground stormge fncilities for fresh water should be available.
This te especially inport=znt in the event of eneny attack where deconta~
mination opurations rmst be initiated shortly after such o attack.

5. additional lighting sheuld be availndle. The four (4) 15C0 watt
fehte vecd during "C.STLE® worse barely adequcie for the purpose intended.
an intensity of illunination four (4) tices es high would be the most
efficient level,
Ground lighting by reane of porteble flevodlights proved
unsatisfactory becnuse of the intense ginre that resulted.
.
6.
Desirnble but not neccessary ore electrical cutlets (110 and 220
volts) beside each wnter outlet.
These are very useful in henting water
(220 volts) end in providing power for auxilinry lights (110 volts).
7. The steel cable stretched between the power poles should be

drawn os taut as possible.
If en individual should slip fron the wing,
the slack cable would cause him to bounce back into the winge
