b. Provide an emergency eyewash/safety shower conforming
Appendix B of UFC 3-420-01. Refer to paragraph 2-8 for discharge
c. Provide an oil separator for drains from the hangar area and paint
mixing rooms and paint equipment cleaning rooms.
d. Locate storm-water drains at least 310 mm (12 in) from the hangar
access door rails.
e. Provide AFFF/sprinkler discharge collection/ retention system when
required by environmental regulations. Provide a connection to the
station Industrial Waste Treatment System or to a collection tank
from all drains. The corrosion control process generates large
amounts of water that could potentially hold solid or liquid paint
residue or other solvents and wastes. \ Refer to UFC 4-451-10,
Hazardous Waste Systems and UFC 4-832-01N, Industrial and Oily

Provide low-pressure air for operation of tools and for breathing air in accordance
with the following criteria:
a. Provide low-pressure compressed air at 40 percent to 60 percent
humidity and at 862 kPa (125 psig) for shop use. Air should be oil-
requiring lubrication should be equipped with an in-line lubricator.
compressed air may be used as a source for breathing air at lower
life cycle costs.
b. Provide low-pressure compressed air at 138 kPa (20 psig) or higher
if required, at 40 percent to 60 percent humidity for breathing air in
the hangar bays. Breathing air may be obtained from the oil-free
shop air source through final purifiers in each bay or from a
separate breathing air compressor and piping system \ that meets
requirements by OSHA for minimum Grade D air. /2/ Breathing air
from the oil-free shop air source is preferred because of lower cost.
c. The air outlets (quick connect fittings) for oil-free shop air,
lubricated tool air, and breathing air should be different for each
service and should not be compatible with each other.
d. Typical outlet quantities for each bay are: four breathing and four
oil-free shop air and two lubricated tool air. Typically, two oil-free
