A. ._areli s
As no valid reason exists for using a high pressure actuatoron item ON 4545 (Arni n '1alve ) , it is requested that the itemList be modified as follois :
1 . Eliminate the request for a • 1ler cylinder and
change cylinder operating pressure from 1700 psig
to 150 psig.
2 . Add request to change this valve from manual to
remote operator by sending this valve to theEquipment laboratory for build up and service to
conform to Rocketdyne Spec . drawing JS 143642-9 .

Santa Susana Field Laboratory Shrapnel Surve y
Upon request, a survey of the test and support areas atSSFL was made to determine if action is necessary at any
facility to correct ; (1) areas designated safe for occupanc yduring test operations, (2) hardware orientation, or (3)
facility test systems, to prevent potential fragments generated
from hardware or facility malfunctions from endangering
personnel . In tis survey, each test position was inspected
and questions were asked of test area supervision concerning
areas designated safe for occupancy during testing . Also
past test incidents were explored from the standpoint ofshrapnel dispersal patterns . From these inspections and
discussions, the following list of action items was compiled .
Specifi c Test Area Items
Canyon - Control of vehicle and pedestrian traffic on theroad to the Research Happy Valley Area should be excercised
during Canyon firing. The road is 550 ft . from Canyon 2,which is 50 ft . further distant than the control center ,At this distance, the road lies within the historical radius
of shrapnel from large engine test stands .
CTL-I - The Lance cold flow tester at Cell -1 is not orientedto take advantage of test cell barricades . The tester is
outside the cell with the top flange having a line of sight
path to the Area I road . Adequate barricading should be
installed .
Bowl - No existing problem areas noted on survey. The
location of the new VTS-1 and VTS-3 pillbox was discussed .This structure should be designed to the Area 's blast limit .
CTL-III - Control of personnel during Module I, II, III andIV testing appeared satisfactory . The analysis of the Cell 39
Space Engine Area should be reviewed and updated with the
additional test positions now active .

CTL-V -- The occupancy of the sheet metal shop building and wooden
office structure during tests of components at the cells is un-
desirable, since these buildings offer little shrapnel protection .
Roadblocks should therefore be placed out of .he area an all tests .
Delta - The Lance fragmentation screening on Delta _ spearsadequate. Inspection of the Delta 3 Lance test area s :ooli hemade when construction is competed and prior to activation .
CTL-IV - The space engine ambient tosts shout,. he continuallyreviewed and assessed to prevent urrating of en gines from occurringwithout a corresponding increase in required safe distances .Gemini engine testing at Cell 24 has resulted in damage to the
facility GN2 main supply line suprcrts . An exhaust as deflector
which would also function as a shrapnel shield shcuLi be installed
to prevent this erosion .
Bravo - Proximity of the NTO storage tank at ra'7o 3 to The _ -tpump test position on 3ravo 2 (approximately ft .) make : r g-mentation screen panels mandatory for protecting this tank.
The 3ravo 3 LEY simulation test piece should have __agment,_tion
screens installed around the tanks .
Alfa - Review of the Alfa-2 Lance missile test facility design
drawings should be made with particular attention t o _ y " enta Dior
screen construction and location .
CTL-II - The use of fragmentation screen panels both portable 'nd
fixed, in addition to steel grating at this facility is excellent
and is an example of a model installation .
Ecuisment Lab . Outdoor high pressure test pits at this facilityshould have overhead screens to prevent vertical or near vertical
shrapnel trajectories .
Instrumentation Lab . - The Gilmore pressure transducer calibrator
should be modified to eliminate the use of high pressure flexhoses and to provide a safer manifolding arrangement . The vise
mounted thermocouple pressure tester is a potential shrapnel
hazard . This tester should be replaced with a pcrmanert fixedunit having safer mounting and restraining devices for holding the
thermocouples in the pressure tester .

General Points in Conclusion.
1 . A noticeable trend was observed at Component Laboratories tomove test hardware out .:_xe the cell or to the outer edge ofthe cell, thereby losing the shrapnel ;r :ze=i :n _ ;'violid bythe cell construction .
2. Space engine testing continues to be a iifficult activity to
adequately control because the relatively low thrust system
and low apparent hazard by 2-second flow standards yes a
false sense of security . it must be recognized that the
2-second rule flow criteria apply only blast Terprsssures,
and that a seperate set of standards must b e a- __d fcr
shrapnel protection at these small engine faci_17ies .
