CHAPTER ll, SECTION 3 vided at each platform level, as well as other standard safety features. An access ladder extended the full height of the tower on the inside of the framing. The tower was supported on four 4-wheel trucks equipped with hydraulic brakes. Movement of the tower was effected by a simple towing winch and cable system between the firing and auxiliary pads located 150 feet apart. The winch waslocated just beyond the auxiliary pad but was controlled from within the tower. Power was supplied from a generator plant located near the site. The power connections to the tower was made through a cord located on the tower and plugged into a receptacle on the firing pad. Lights and receptacles were provided at all platform levels. The foundation for the tower at the firing and auxiliary pads consisted of a concrete mat 36 feet square and 214 feet thick. Provision was made to tie down the tower to its foundation when it was subjected to high winds. This was accomplished through the use of bolts connecting the tower wheel trucks to metal plates embedded in the foundation. Approximately onehalf the number of connector bolts proposed for use at Site How was used because the removal of the tower siding reduced the uplift. Each pair of tower rails between the two foundations was set on concrete 8 feet wide and 134 feet thick. The tracks were placed on 8x8 timber seats spaced 8 feet on centers, then concreted in place. Two sandbag revetmentsfor trailers were located about 100 feet from the firing pad and about 40° apart. They were 13 feet high, with one 20 feet long and the other 30 feet long. Each had 12-foot-long wing walls. Each of two small concrete revetments were located 80 feet from the firing pad and 50° apart on the windward side of the pad. They were 12 feet long, 6% feet high, with 10-foot-long wing walls and were used to house fire protection water nozzles. The fire was supplied turbine diesel on an intake protection system for this station with sea water from two vertical engine-driven fire pumps mounted structure located at the edge of the lagoon with intake lines extending into the lagoon. Each of these pumps had a capacity of 1000 gpm at a discharge pressure of 100 psi which gave a total fire-fighting capacity of 2000 gpm with both pumps operating. The pumps were manually started and operated continuously while fire protection was required, maintaining a constant pressure in thefire lines. Ample diesel fuel storage and supply for the engines were provided. The discharge from the pumps was run through a surface-installed fire line terminating at the two concrete fire protection revetments. Twofixed monitor type fire nozzles were mounted on each revetment to direct the water stream Page 138 (Neg. No. W-958-12) Figure No. 2-74. Fire Protection Revetment at Station J-6001. directly on the firing pad at the base of the missile. Water was supplied to these nozzles by re- mote control with the operating switch located in the Bunker, Station J-6002. This switch ener- gized an electric solenoid air pilot which supplied air to pneumatic valve operators. Air for the valve operators was supplied by an automatic air compressor installed behind one of the concrete revetments. Additional fire protection was provided by a fire hydrant installed in the area with an ad jacent hose house containing required hose, nozzles, and other necessary fire fighting equipment. Cable ditches were provided between th: trailer revetments, between the firmg pad ana the 30-foot trailer revetment, and to Station J-6002. Pipe sleeves were placed in the concret track support where the ditches crossed th tracks. A concrete pull box was provided to the end of the cable ditch at the edge of the firing pad tower foundation. Three 12-inch-diamete pipes extended from this pull box to three quac rants of the foundation. An 8-inch pipe conduit was placed from the 20-foot trailer revetment to one of the 12-inch pipes at the tower found: tion. A skid-mounted timber personnel shelter, 12 feet square and 7 feet high, was placed close to the firing pad. It contained receptacles an lights circuited to a portable plug which connec ed to a power receptacle on the pad. The entire firing pad area was illuminat« by floodlights, as well as the railway between and the auxiliary pad. Receptacles were providea throughout the pad area for trailers and miscellaneous equipment.
