NAVSEA OP 5 VOLUME 1 FIFTH REVISION
g.
When chemical agents are involved, information regarding
personnel protective clothing and equipment, treatment of effluent and
waste materials to ensure absence of chemical agents, adequacy of
medical support, average wind speed and direction, other support
facilities pertinent to chemical safety, warning and detection sys-
tems, and hazard analysis.
h.
Explanation of any deviations from pertinent safety
standards due to local conditions.
8-1.3.  PROTECTIVE CONSTRUCTION POLICY. The requirements for protec-
tive construction permit achievement of any calculated level of
protection from explosion communication between adjacent bays or
buildings, from death or serious injury caused by incidents in
adjacent bays or buildings, and from damage to vital and expensive
equipment installations. Therefore, the major objectives in facility
planning should be to:
Provide protection against explosion communication between
a.
adjacent bays or buildings and protection of personnel against death
or serious injury from incidents in adjacent bays or buildings.  Refer
to paragraphs 7-3 and 7-9.  Planning should reflect opportunities
where the protection of personnel and facilities would be greatly
enhanced or costs significantly reduced by having separate buildings
to limit explosion propagation rather than using protective construc-
tion and separation of explosive units within one building.
Provide protection for vital and expensive equipment if the
b.
additional cost is warranted.
C.
Harden a target building or construct a source building to
suppress explosion effects. When either provides an appropriate
degree of protection,  these factors may be taken into account and the
distances required by the standard quantity-distance tables may be
reduced.  Site and general construction plans for ammunition and
explosives facilities that propose reduced distances based upon
protective construction must be accompanied by the rationale or test
results justifying the reduction when they are submitted for approval.
Refer to paragraph 9-1.2.3.
8-1.4.  PERSONNEL PROTECTION. Structural design and construction
plans will meet requirements for protection from blast, fragment, and
thermal hazards in facilities where workers are exposed to ammunition
or explosives hazards during industrial, processing, manufacturing,
maintenance, renovation, demilitarization and similar operations.
NAVFAC P-397 contains design procedures to achieve personnel
protection as required by these regulations, to protect facilities and
equipment from damage by blast, fragments and debris, and to prevent
propagation of explosions.
Refer to paragraph 7-6 for analysis of
hazard, permissible exposure, and protective measures to be taken.
