Oxygen And Fuel

[Lakeview Bill]

Does anyone know of any guidelines regarding the minimum safe distance
between oxygen equipment (tanks, high pressure lines, low pressure lines)
and fuel system equipment (tanks, lines, valves)?

Thanks!

8-30b Fuel Systems

b. Routing. Make sure that the line does

not chafe against control cables, airframe

structure, etc., or come in contact with electrical

wiring or conduit. Where physical separation

of the fuel lines from electrical wiring or

conduit is impracticable, locate the fuel line

below the wiring and clamp it securely to the

airframe structure. In no case should wiring be

supported by the fuel line.



11-126. FLAMMABLE FLUIDS AND

GASES. An arcing fault between an electrical

wire and a metallic flammable fluid line may

puncture the line and result in a fire. Every effort

must be made to avoid this hazard by

physical separation of the wire from lines and

equipment containing oxygen, oil, fuel, hydraulic

fluid, or alcohol. Wiring must be

routed above these lines and equipment with a

minimum separation of 6 inches or more

whenever possible. When such an arrangement

is not practicable, wiring must be routed

so that it does not run parallel to the fluid

lines. A minimum of 2 inches must be maintained

between wiring and such lines and

equipment, except when the wiring is positively

clamped to maintain at least 1/2-inch

separation, or when it must be connected

directly to the fluid-carrying equipment. Install

clamps as shown in figure 11-10. These

clamps should not be used as a means of supporting

the wire bundle. Additional clamps

should be installed to support the wire bundle

and the clamps fastened to the same structure

used to support the fluid line(s) to prevent

relative motion.
