b) Makeup air, heated as required, for dust collector exhaust
system if grit blast cleaning equipment is provided.
c) Ventilation for battery shop, if battery charging equipment is
supplied, as required by Section 5, Part 6, NAVFAC DM-28.04, General Main-
tenance Facilities.
2.3.3
Plumbing. Plumbing shall be provided in accordance with NAVFAC
DM-3.01, Mechanical Engineering - Plumbing Systems.
Specifically provide:
a) Cold water supplies with hose-bibb outlets to main shop areas.
Steam or hot water supplies to main shop areas that require washout opera-
tions. Cold water supply to the paint booth when waterwash type is provided,
Hose-bibb outlets shall be equipped with vacuum breakers.
b) Floor drains in main shop areas and a drainage system for the
paint booth when waterwash type is used. Connect drains to waste systems as
required to comply with pollution control requirements (refer to
para. 6-3.2.2, Vol. 1, NAVSEA OP-5, for requirements concerning drain lines
handling explosive wastes). There shall be no drains from the paint spray
booths . Floor drains may be connected to the sanitary system in areas where
there is no Otto fuel present. There shall be no floor drains in the Otto
fuel areas or provide trench and sump system for spill control.
c) Emergency showers and eyewashes when pyrotechnic or toxic
chemical materials are handled in the facility. Determine specific require-
ments based on materials used in the facility.

Compressed Air. Compressed air shall be provided at 100 psi (689
kPa) in accord with NAVFAC DM-3.05, Compressed Air and Vacuum Systems, for
air hoist motors, painting equipment, tools, etc. Provide outlets at work
benches and other work areas. Compressed air supplies shall be clean, dry
and utilize filters and dryers. Consider the requirements of the facility to
determine if a separate air compressor should be provided rather than
utilizing a central air supply. A separate air compressor would assure that
an adequate quantity of compressed air is available. Separate air compres-
sors may also provide lower operating and distribution costs. Refer to para.
7-2.5, Vol. 1, NAVSEA OP-5, for authorized use of compressed air.
2.3.5
Noise and Vibration Control. All mechanical systems and equipment
shall be designed to limit noise and vibration in accord with NAVFAC DM-3.10,
Noise and Vibration Control for Mechanical Equipment (ARMY).
2.4
Electrical Retirements. Electrical requirements, including power
generation and distribution, lighting, grounding, and lightning protection
shall be in accord with Chapter 4, Vol. 1, NAVSEA OP-5, NFPA 70, National
Electrical Code, NAVFAC DM-4 Series, Electrical Engineering, and as defined
in paras. 2.4.1 through 2.4.3 of this handbook.
2.4.1
Power. Single-phase, 120 Vat, 20 A, 60 Hz, convenience outlets
shall be provided in all spaces with spacing as required by NFPA 70 and the
using activity. Equipment and wiring in the paint shop shall be in accord
