SAFETY REQUIREMENTS. Requirements for personnel safety must meet the
standards listed below:
a.
Ventilation. The following ventilation systems shall be provided
in accordance with Heating, Ventilating, Air Conditioning and Dehumidifying
Systems, NAVFAC DM-3.3.
(1)
Exhaust fans to remove fumes and toxic gases.
(2)
Dust collectors to reduce explosion hazards.
b.
Identification of Hazardous Areas. Hazardous areas shall be iden-
tified by means of colored safety markers on floors, columns, and structural
elements projecting into circulation areas. (See Architecture, NAVFAC DM-1,
Chapter 3, Section 5 and Color for Naval Shore Facilities, NAVFAC P-309,
Chapter 5.)
c.
Spacing. To ensure operator safety, specified aisle widths and
spaces surrounding machines shall be maintained.
d.
Collection Facilities. Bins shall be provided for shavings,
scrapings, filings, and liquid coolant wastes.
7.
LOADING DOCK RAMP PROTECTION. Each facility requiring a loading dock
ramp shall be provided side edge protection in accordance with Section
1910.23c, Occupational Safety and Health Act Standards Manual.
8.
ENERGY CONSERVATION. Energy conservation shall be a major consideration
in the design of building envelopes, mechanical systems, and electrical
systems for general maintenance facilities. (See NAVFAC DM-3.3 and Energy
Budgets for New Facilities, NAVFAC Inst. 4101.1.) Each building envelope shall
be insulated to provide the minimum heat transmission ("U") factors practical
to meet energy budgets.
9.
ENVIRONMENTAL CONCERNS. The maintenance facilities shall meet all
applicable pollution abatement criteria. For applicable discharge criteria
NAVFAC HQ and the cognizant EFD should be consulted. Also see NAVFAC Design
Manual 5.8, Pollution Control Systems, Design Manual 5.9, Metering, lnstru-
mentation and Control, and Chemical Feeding, and NAVFAC Inst. 4862.5A, Waste
Control Projects Involving Wastewater, Chemicals and Toxic Substances.
It is essential that, as part of the preliminary studies, consideration be
given to water conservation and source control, including the possibility of
substantial alteration of the process or plant operation to reduce pollutant
loading. The greater the volume of wastewater to be treated and the greater
the amount of contaminant to be removed or destroyed, the higher are the capi-
tal, labor, and material costs required. Therefore, it is often economical to
eliminate or reduce the quantity of waste at its source prior to treatment or
in place of treatment. Several possible techniques exist including process
change, material recovery, segregation, and waste reuse. Sometimes, with only
partial purification, spent water can be reused, once or several times, in the
industrial process. Water unsuitable for direct reuse may be serviceable for
a different purpose in which quality requirements are less restrictive.
