2.4.2. Lining and decompression (All Airbus aircraft):
The ceiling, sidewalls and floors of the cargo compartment have fire and impact resistant linings
complying with —JAR/FAR 25 Amendment 60“.
The floor panels and the linings are of sandwich type, manufactured from honeycomb, prepreg
layers and protection foil or metal sheet.
The installed linings and floor panels are designed for the following:
. Handling loads from loading personnel.
. Surface finish in light color.
. Quick release features necessary for accessibility.
. Rapid decompression requirements according to FAR/JAR.
. Leak proof requirements for class C compartments according to FAR/JAR.
. Flammability requirements according to FAR/JAR.
. Low smoke and toxicity requirements. The sidewalls and partitions are equipped with rapid decompression panels. Each decompression panel is enclosed within a frame and is held in place by decompression assemblies.
Decompression panels
In case of —blow in“ spring loaded snappers are pushed back, in case of —blow out“ the frame of the decompression panel brakes to allow decompression panel displacement.

2.4.3. Drainage (All Airbus aircraft):
To prevent accumulation of water in the cargo compartments, numerous drain-outlets are provided in forward and aft cargo compartments and in the bulk compartment floor. Drain funnels are installed in the roller tracks, in sumps and in the floor in front of slushing dam. The drain outlets consist of a mounting housing, acting as a coarse filter, which contains a sponge filter element. Hoses are connected to the drain outlets, leading to the bilge area, which is provided, with drain valves.
2.4.4. Cargo compartment lighting (All Airbus aircraft):
A separate lighting system is installed in each cargo compartment. All lights are manually controlled by means of switches. The control switch is installed adjacent to the cargo door for the respective compartment. Each cargo hold is provided with a minimum light level of 50 lux at the hold floor. For the lighting of the loading area, a spotlight is installed in each door ceiling area. The loading area light is sufficient to allow reading of labels on the ground loading equipment,

2.4.5. Heating and ventilation
a) in bulk cargo compartment (A310/A300/A330/A340):
Cabin ambient air is supplied to the bulk cargo compartment through a distribution duct along the left-hand side of the compartment. On request, an electrical heater can heat the air. The air is extracted from the bulk compartment by an electrical fan through vents near ceiling on the right-hand side. The extracted air from the bulk cargo compartment is passed under the bulk compartment floor to provide floor heating. In the bulk cargo compartment, isolation valves are fitted in the inlet and outlet ducts to isolate the cargo compartment in case of smoke warning.
