The pressure relief assembly in
LOX system storage vessels
consists of which of the
following items?
1.
A ruptured disc
2.
A reseatable relief valve
3.
Both 1 and 2 above in series
4.

6-34.
Which of the following statements
is correct concerning the stowage
of LOX containers?
1.
Hydrocarbons in the vicinity
of stowed LOX containers do
not present a hazardous
condition
2.
LOX containers should not be
stowed in the vicinity of
flammable gases or liquids
3.
Because of the insulation in
LOX containers, open, outside
stowage is desirable
4.
Stowage of LOX containers
must be in refrigeration
spaces
6-35.
When dealing with LOX leakage or
spillage, which of the following
actions should be taken?
1.
Immediately mop up the LOX
and hose down with water
2.
Immediately hose down the
area with water
3.
Dilute the LOX with a caustic
soda and hose down with water
4.
Ventilate the leakage or
spillage to allow LOX to
evaporate into the atmosphere
6-36.
What action should be taken when
an article of clothing you are
wearing comes in contact with
LOX?
1.
Separate the article of
clothing from skin contact
immediately, and thoroughly
air clothing to allow
dilution of the oxygen
2.
Apply large quantities of
water to the clothing area
that has come in contact with
the LOX
3.
Remove the contaminated
article of clothing and
discard
4.
Remove the contaminated
article of clothing for
washing
6-37.
For what reason must a completely
empty aircraft LOX converter be
serviced slowly?
1.
To allow the system to be
completely filled
2.
To prevent possible damage to
the converter by thermal
shock
3.
To allow the safety valves in
the system time to adjust to
the servicing
4.
To prevent the thermal relief
valve from operating
prematurely
6-38.
What is the advantage of using
liquid oxygen systems over
gaseous oxygen systems on
aircraft?
1.
Liquid systems are 1ess
dangerous
2.
One LOX converter replaces
several cylinders of gaseous
oxygen
3.
Liquid systems are more
efficient
4.
Liquid oxygen is more
economical to manufacture
