<3> Is there an explosive bomb threat? If the design threat
includes explosives, the activity chart branches to Elements <4> and <5>.
Section 8 summarizes the procedures for selecting vehicle barriers to stop
the threat at an adequate standoff as well as to design the building to
sustain any resulting blast effects from that distance.
<4> Establish vehicle barriers and available blast zone distance.
Paragraph 8.4.2 summarizes design approach for the structural hardening new
construction, and par. 8.4.3 does the same for retrofit against bomb blast.
This includes the exterior walls, roofs, doors, windows, and frame of the
building. The construction chosen for these components should be entered in
the "Facility Exterior" portion of the worksheet (Appendix A).
<5> Establish structural blast hardening. Paragraph 8.4.2
summarizes the structural hardening design approach for new construction, and
par. 8.4.3 does the same for retrofit against vehicle bomb blast at the given
design threat. This includes the exterior walls, roofs, doors, windows and
frame of the building. The construction chosen should be entered in the
"Facility Exterior" portion of the worksheet.
<6> Is there a standoff weapon threat? If the design threat
includes standoff weapons, the flow chart branches to Elements <7> and <8>.
Section 7 summarizes procedures for hardening a building against a standoff
rocket propelled grenade (RPG) attack.
<7> Exterior siting for standoff weapons. Paragraph 188.8.131.52
presents facility siting considerations to limit or block RPG attack sight
<8> Sacrificial exterior design for standoff weapons. Paragraph
184.108.40.206 presents guidelines for designing a sacrificial exterior shell as an
option to reduce the effectiveness of an RPG attack.
<9> Exterior barrier standoff weapon hardening for standoff
weapons. Paragraphs 7.4.1 and 7.4.2 provide guidelines for designing
barriers (both new and retrofit) to stop an RPG attack. The construction
selected should be entered into the "Facilities Exterior" portion of the
appropriate worksheet (Appendix A).
<10> Is there a ballistics threat? If the design threat includes
ballistic weapons, the flow chart branches to Elements <11> and <12>.
<11> Exterior siting for ballistic weapons. Paragraph 220.127.116.11
presents facility siting considerations to limit or block firearm attack
<12> Exterior barrier ballistic hardening measures. Paragraph
18.104.22.168 provides barrier hardening design options to counter a given
