*
Cargo compartments have fire extinguishing systems which operate from the flight deck
*
Compartment linings and the environmental control systems keep dangerous quantities of smoke and extinguishing agent out of the passenger and crew cabins
*
Compartment linings meet specified burn through requirements.
Cargo linings make a closed area for the cargo compartments but permit access to other systems. Closed compartments are necessary for fire protection and temperature control.
WARNING: SEAL THE COMPARTMENT WITH THE LINERS. OBEY THE INSTRUCTIONS IN THE SPECIFIED PROCEDURE WHEN YOU INSTALL THE LINERS. IF YOU INSTALL THE LINERS INCORRECTLY, THE FIRE WILL NOT BE CONTAINED AND THE EXTINGUISHING AGENT OR SMOKE CAN GET INTO THE PASSENGER COMPARTMENT DURING A FIRE.
Lower lobe cargo compartments have these items:
*
Bulk cargo door protector
*
Bulk cargo net
*
Floor panels and walkways
*
Fiberglass liners
*
Neoprene-coated liner
*
Decompression panels
*
Nomex honeycomb panels.
Training Information Point
When you work in the cargo compartment, install a safety barrier in the doorway.
WARNING: INSTALL THE SAFETY BARRIER CORRECTLY WHEN THE CARGO DOOR IS OPEN. IF YOU DO NOT CORRECTLY INSTALL THE SAFETY BARRIER, PERSONS CAN FALL OUT OF THE CARGO COMPARTMENT AND INJURY CAN OCCUR.

LOWER LOBE CARGO COMPARTMENT -FIBERGLASS LINERS
Purpose
Fiberglass liners help isolate the cargo compartments from other parts of the airplane for fire protection and temperature control. The bulk cargo compartment liners also help transmit cargo loads to the airplane structure.
Physical Description
These cargo compartment liners are made from rigid fiberglass material:
*
Sidewall liners
*
Ceiling liners
*
Station 1437 end wall.
These devices attach the fiberglass liners to the structure:
*
Bolts
*
Screws
*
Scrivets
*
Hook-and-loop tape.
Tape seals the edges and seams.
Location
Sidewall liners extend from the floor to the ceiling along both sides of the forward, aft and bulk cargo compartments. The upper liner is a vertical sidewall liner. The lower liner is a sloping sidewall liner.
Ceiling liners make the ceilings of the cargo compartments.
The station 1437 end wall is at the forward end of the aft cargo compartment.
Training Information Point
You must repair fiberglass liners which have cuts, tears or holes. If the damage is in specified limits, you can repair the liner with a patch. Otherwise you must replace the damaged liner. Special patch kits permit you to make bonded patch repairs without removing the liner from the airplane.

LOWER LOBE CARGO COMPARTMENT -NEOPRENE-COATED LINER
Purpose
Neoprene-coated liners help isolate the cargo compartments from other parts of the airplane for fire protection and temperature control. Neoprene-coated liners are also access panels to equipment behind them.
Physical Description
The liners are made from flexible neoprene-coated fiberglass. Snaps hold the liners in place.
Location
The station 998 end wall is a neoprene-coated liner. It is at the aft end of the forward cargo compartment. Some of the vertical sidewall linings (not shown) in the forward and aft cargo compartments are also this type.
Training Information Point
You must repair cuts, tears or holes in the neoprene-coated liners. If the damage is in specified limits, you can repair the liner with a patch. Otherwise, you must replace the damaged liner.
