___________________________________
A. General
(1) This inspection procedure is to be done when liquid has been spilled in the galley area.
NOTE: When a small amount of liquid is spilled, an inspection is
____
not usually necessary.
(2)
In the galley areas, a water (liquid) barrier is installed to contain liquid when it is spilled. To protect the water barrier, vinyl mats cover the galley floor.
(3)
In the adjacent entry and service door thresholds, waste water drains are installed to remove liquids (gray water) from the floor. These drain holes must be kept free from blockages.
(4)
The integrity of the water barrier seal, in the forward galley areas, is most important because the location of the electronic equipment compartment is directly below the forward galley.
(5)
A leak from the forward galley which has a damaged water barrier, into the compartment below, could possibly cause serious damage to the electronic equipment. The result could be a possible hazzard to the flight safety of the airplane.
