TO KEEP them in first-class condition for
periods as long as thirty years, gas masks
being manufactured at the U. S. arsenal at
Edgewood, Md., are sealed in special vacuum
containers. After the masks have been as-
sembled and tested, they are placed in cor-
rugated metal containers. These are fed into
a compressing machine which removes all
air from the container and seals a metal lid
in place. To make doubly sure that no air
leaks in, the sealed containers are then
soldered at the joints. Eight hundred work-
ers at the Edgewood plant are turning out
masks at the rate of about 3,000 a day to
build up a huge reserve supply for possible
future need. The photograph at the left,
above, shows women workers on the assem-
bly line attaching canisters to the otherwise
completed masks, while in the picture at the
right a workman is shown placing the mask-
filled container in the compression machine
for sealing.
