Identify components and
operating procedures for
gaseous oxygen servicing
What maximum number of manifold
control valves are located on the
No-2 oxygen trailer?
The No-2 oxygen trailer has two
pressure regulators to ensure
uninterrupted operation should
The recharge valve on the No2
oxygen trailer is provided for
recharging the trailer cylinders
directly through what device(s)?
The lower manifold
The upper manifold
One of the two pressure
The servicing hose and line
Where are the four shutoff valves
located on the No-2 oxygen
1. On the upper manifold
2. On the lower manifold
3. One onthe inlet and outlet
side of each pressure
4. On the drier assembly
8-5. The lower manifold is connected
to the drier assembly by what
hose or line?
8-6. The oxygen flows through the top
of the dryer, passes down through
the drying agent, and out through
the servicing hose.
8-7. Because gaseous oxygen cylinders
must never be completely drained.
residual pressure in O2 cylinders
should never be allowed to fall
below what minimum pressure?
8-8. Prior to removal or installation
of oxygen cylinders on the No-2
oxygen trailer, cylinder safety
caps will be installed.
8-9. After 12 cylinders of oxygen have
been used, the drying agent
should be subjected to what
8-10. What is the color of the drying
agent in the dryer?
