After doors are open, door handles must be re-latched in their closed position to prevent
equipment damage to handles as doors are folded back into the open position.
The FPU-8 end container doors are retained by fabric-covered chains shackled to welded rings on
the end and interior of the door. Secure doors using door restraints.
To prevent injury to personnel, after opening each door install door restraints to prevent
accidental closing due to wind, or when container is resting on an non-level surface.
