7. Q. What care must be exercised in the use of lamps, torches or
lanterns about oil tanks whether hot or cold?

A. Never permit oil lamps or oil torches to be carried within ten feet
of the tank opening. Only incandescent lamps or pocket flash lights
should be used around oil tank manhole when taking oil.

8. Q. How can oil in the tank be measured without taking a light to the
manhole?

A. By inserting a measuring stick into oil in tank and taking stick to
the light for reading.

9. Q. What precautions must be taken before entering tanks that have
been used for oil to clean or make repairs?

A. Oil tanks, before being entered by workmen, should be thoroughly
steamed and cooled before being entered. For safety they should be
steamed from six to eight hours.

10. Q. How should the fire be lighted in an oil burning locomotive?

A. First see that no one is working under the engine, that there is the
proper amount of water in the boiler and that it will flow through the
gauge cocks, that there is no accumulation of oil in the ash-pan or
fire-box or existing leaks throughout. If there is no steam in the
boiler, the steam connections can be made to the three-way cock at the
smoke-arch that will answer for blower and atomizer. If there are twenty
pounds of steam in the boiler, it can be operated with its own blower.
