B-3.1.7.3
Other Existing Buildings. For existing buildings that are not required to
comply with these standards, window retrofits incorporating fragment retention film or
blast curtains are considered to be viable and economical solutions to mitigating the
effects of explosive attacks, but should be evaluated prior to installation so that
reduction in glass hazards may be determined.
B-3.2
Standard 11. Building Entrance Layout. The areas outside of
installations are commonly not under the direct control of the installations. Where the
main entrances to buildings face installation perimeters, people entering and exiting the
buildings are vulnerable to being fired upon from vantage points outside the
installations. To mitigate those vulnerabilities apply the following measures:
B-3.2.1
New Buildings. For new inhabited buildings, ensure that the main
entrance to the building does not face an installation perimeter or other uncontrolled
vantage points with direct lines of sight to the entrance or provide means to block the
lines of sight.
B-3.2.2
Existing Buildings. For existing inhabited buildings where the main
entrance faces an installation perimeter, either use a different entrance as the main
entrance or screen that entrance to limit the ability of potential aggressors to target
people entering and leaving the building.
Standard 12. Exterior Doors. For all new and existing buildings covered
B-3.3
by these standards where the conventional construction standoff distance is met or
exceeded, ensure that all exterior doors into inhabited areas open outwards. By doing
so, the doors will seat into the door frames in response to an explosive blast, increasing
the likelihood that the doors will not enter the buildings as hazardous debris. Where the
standoff distance available is less then the conventional construction standoff distance,
design the doors to achieve the applicable performance in Table 2-1.
B-3.3.1
Glazed Doors. In addition to the provisions above, glazing in glazed
doors must meet the glazing and frame bite provisions of Standard 10.
B-3.3.2
Alternative Designs. As an alternative to the above provisions for all
doors, position doors such that they will not be propelled into rooms if they fail in
response to a blast or provide other means to ensure they do not become hazards to
building occupants. The glazing in glazed doors must still meet the provisions above if
this alternative is exercised.
Standard 13. Mail Rooms. The following measures address the location
B-3.4
of rooms to which mail is delivered or in which mail is handled in new and existing
inhabited buildings. These standards need not be applied to mail rooms to which mail is
delivered that was initially delivered to a central mail handling facility. These standards
should be applied to such mail rooms where possible, however, to account for potential
changes in mail handling procedures over the life of the building. The measures involve
limiting collateral damage and injuries and facilitating future upgrades to enhance
protection should they become necessary.
