HEAT, LIGHT, AND VENTILATION
factors: (1) the operational needs of the battalion
Heat, light, and ventilation for a large,
permanent maintenance shop are included in the
plan specification. However, the installation of
these facilities in the small or temporary shop
depends on the maintenance supervisor.
The decision of whether to heat your shop
depends upon its geographical location. Heaters
should be arranged to provide warmth where it
is most needed. Persons working at benches or
in the shop store require more heat than people
working in the main shop for comparatively short
periods. For this reason, you should place heaters
in corners convenient to workbenches and away
from shop doors.
For adequate lighting, most maintenance
shops depend upon lights arranged in the
overhead of the main shop, lights and windows
near the workbenches, and extension lights that
can be plugged into electrical outlets. When you
are in charge of setting up a maintenance shop,
make sure that enough electrical outlets are
provided for extension lights and electric power
tools. Only the most elaborate shops have enough
windows for efficient lighting.
Removing exhaust gases becomes a big
problem in every maintenance shop. Large doors
in the front and rear of the shop and windows
at the workbenches normally supply all the fresh
air needed, but even these are inadequate to remove
excessive amounts of exhaust gases. These gases
rise and are trapped in the shop overhead unless
roof openings with ventilating fans are provided.
Normally, it is up to the supervisor of a temporary
shop to provide his own method of ventilation.
A piece of flexible steel or neoprene hose attached
to the exhaust on a running engine and carried
outdoors through an opening in the building will
serve the purpose. Do not allow any unnecessary
operation of an engine inside the shop.
When stationary gasoline or diesel engines are
used to produce power in the maintenance shop,
provide exhaust outlets for them. Do not depend
on natural ventilation through door and windows.
At least once during each deployment have the
maintenance shop evaluated by the local base
industrial hygienist, if the service is available. Do
this through your battalion safety office.
TOOLS AND EQUIPMENT
The quantities and kinds of tools and equip-
ment required for a maintenance shop vary with
each shop. In deciding what tools and what type
of equipment to have on hand, consider two
and (2) the cost of the work at a component
overhaul facility. Of course, the needs of the
service come first, but not entirely without cost
justification. Base your decision concerning the
second factor solely on the facts and figures given
in transportation maintenance management reports.
In a maintenance shop setup for repairing all
types of equipment, you will coordinate and
supervise work on many different types; therefore,
study carefully the layout of the shop and the
placement of shop equipment. You will probably
be the one to decide whereto put the shop equip-
ment. This is where experience counts, You should
know where the repair equipment is needed and
where it will be accessible to the operators who
will use it. Without careful planning you can waste
a lot of space and time in shifting equipment from
one place to another. If space in the main shop
is critical, special repair equipment can be put in
smaller shops or rooms adjoining the main shop.
Power tools, such as drill presses and bench
grinders commonly used in repairing all kinds of
equipment, should be located in or near the main
shop area. The locations of other power tools,
such as hydraulic or electric lifts, valve grinders,
and machines for aligning wheels and relining
brakes, depend on where the tools will be best
utilized. The master switch that controls all power
in the shop should be installed where it can be
reached quickly in an emergency.
In placing power tools, secure the legs or bases
to a level surface strong enough to support them
and make sure they will not move or bounce when
in use. Before connecting stationary, electrically
operated power tools to power outlets, be sure
that each one is positioned so that the starting and
stopping switch is within easy reach of the
operator. Ground-fault interrupters should be
installed to prevent accidental electrical shock.
When the connection is complete, test the tools
to ensure that the installation is safe. Also, let
your mechanics operate them and consider any
suggestions they may have for improvements. As
always, make sure your tool and equipment
operators wear protective gear. Double-check
often, looking for ways to improve the efficiency,
as well as the safety, of the whole maintenance
Welding equipment must be operated in an
area apart from the rest of the shop. Post hazard
warning signs in the area and equip it with fire-
fighting equipment. Erect screens that will confine
flying sparks to reduce the chances that they will
start fires or get into somebodys eyes.
