DANGER
Do not install any flammable material directly above or around the compartment. Heat, trans- ferred through the compartment structure, may be sufficient to ignite, char or discolor seat cush- ions, fiberboard and other flammable materials. Use approved nonflammable insulating materi- als in high temperature areas.
2.2.3 SOUND INSULATING MATERIALS
Once installers have determined that a compartment is properly constructed and metal lined, they can add acoustical material. This may include additional seal- ant or insulating material, to reflect noise away from the vehicle interior.
Sound insulating materials should be of a nonflam- mable type. One excellent insulating material is a 1- inch (25 mm) thick fiberglass having a
Any method used to reduce noise must not adversely affect the flow of cooling and ventilating air into or out of the compartment.
In addition to the effective use of sound insulating materials, construction of a special noise abatement compartment might be considered to reduce noise levels. Such a compartment might be constructed as follows (Figure 2.6):
•Use
•Construct the compartment floor of a double thick- ness of
•Line the compartment interior walls and floor, as well as the underside of the floor, with
•Vapor seal all compartment seams and joints.
•Over the galvanized steel lining, install a combina- tion of acoustical materials.
DANGER
To prevent fire or explosion, do not install any insulation or other absorbent materials on the interior or underside of the compartment floor.
•Seal all compartment door edges to prevent noise leakage around the door perimeter.
•Line the compartment door interior (except for air openings) with suitable, fireproof sound insulation (such as

DANGER
Do not install sound insulation or any absorbent material on the compartment floor interior. Such materials will become soaked with combustible or explosive vapors and liquids and will become a fire hazard.
Using a combination of sound insulating materials can often reduce noise more effectively than a single material. For example, a sheet of lead or

For additional noise abatement, the installer may wish to consider the following:
•Using special sound insulating materials.
•Construction of a special noise abatement com- partment.

2.2.5 COMPARTMENT FLOOR CUTOUTS
Provide openings in the generator compartment for the following items (Figure 2.7):
•Engine exhaust and cooling air outlets
•Generator cooling air inlet
•Four holes for passage of generator mounting bolts.
