This temperature is about that which the hand can bear on the outside of
the tank.

3. Q. If the oil is too warm, what happens?

A. Many of the good qualities of the oil may be lost by keeping it too
warm, and the burner is more difficult to operate and does not work as
well when the oil is kept at too high a temperature. Should the oil be
too warm, it will give off too much gas which would be liable to cause
an explosion in the oil tank.

4. Q. What tools are necessary for firing purposes on an oil burning
locomotive?

A. The tools necessary for firing an oil burning engine include sand
horn, brick hook, and a small iron bar to be used in cleaning carbon
from the mouth of the burner.

5. Q. What is liable to happen if the heater valve is open too much?

A. If the heater valve is opened too much it would be liable to burst
the heater hose as well as to heat the oil to a too high temperature and
place an unnecessary strain on all the heater connections, causing them
to leak.

6. Q. What should be done on approaching stations where additional
supply of fuel oil is to be taken?

A. Shut off the fire, close safety and main oil valves, remove any lamps
that are so close as to be unsafe when manhole cover is open.
