2. REQummENT
S AND DESIGN OBJECTIVES
2-:1
FLAMMABLE FLUID TANKS (See Figures 1,
2 and 3 on p%esg, U and 13)
2.1.1 GR?ERAL
2.1.1.1 TANK 10CATXO!Y
2.1.1.1.1 TANKS IN ENGINE CCMPAR!I!MENTS
Fuel tanks shall not be located in engine computments.
Oil, hydraulic,
and water-alcohol tanks may be located in
compressor sections of engine compartments, but shall be designed to
withstand a 2000°F fire for 10 minutes without leakage. Oil,
hydraulic, and water-&Lcohol tanks in compressor sections of engines
should be kept,
as far as practicable,
tow=d the front of the compres-
sor and be located as low as practicable.
These tanks shall not be
located adjacent to burner,
turbine and tailpipe =eas. Oil tanks for
auxiliary power plants may be located in their surrounding compartments
but shall be designed to withstand a 2000°F fire for 10 minutes without
leakage.
2.1.1.1.2 TANKS AB3VE ENGINE CCBMR!R4ENTS
Location of fuel tanks above engine compartments should be
avoided.
If fuel tanks -mustbe located above engine comp=tments for
justifiable reasons
, provisions shall be made to prevent leakage of
fuel into engine compartments or onto exhaust systems. A ventilated
and drained s-paceshall be provided between fire wall and tank to afford
safe disposal of any fuel leakage from the _Lank.
Insulation shall also
be provided,
if necessary, to prevent i~ition within
the tank, or in
the shrouded air space,
h x
of a power plant fire.
Such insulation
sha~ be nonabsorbent as a material configuration and shall be suitable
for periodic inspection.
