Diesel Generators

1.2.3

Diesel Generators .

Diesel generators are generally located outside, in their own weather-tight

enclosure. When diesel generators are located inside, the engine

exhaust silencers may be located inside the room or on the building roof;

in either case, the silencers should be accessible for inspection.

Due to the noise and vibration levels in these rooms, the diesel engine

controls should be located in a separate room.

Diesel engine air intakes should not be located near any volatile gas

sources and the bottom of the intake should be a minimum of 20 feet

above grade.

For indoor location of diesel generator units, an overhead bridge crane

sized to lift the generator should be provided for maintenance.

Alternately, a rigging beam over each generator may be used.

1.2.4

Auxiliary Lifting Devices . Hoisting, lifting, and rigging are an integral part of

operations at DOE facilities. This section provides general guidelines to be

considered for plant layout and arrangement for the selection and application of

auxiliary lifting devices. Additional guidance is provided in DOE-STD-1090,

Hoisting and Rigging.

Bridge Cranes. Bridge cranes rated up to 75-ton capacity should be used in

such areas as workshops, drum storage areas, radioactive machine shops, and

for the maintenance of individual pieces of equipment. Hoists should be used

with bridge cranes to increase the crane use. Crane clearance requirements and

the limits on hook travel are special considerations to be looked into when

selecting bridge cranes.

Hoists. Hoists are available with electric, pneumatic, or manual operators. The

following provides guidance on the selection of a hoist.
