b. The EOC must be habitable following an emergency (e.g.,
shielded, ventilated) or an alternate EOC should be available
if the primary EOC becomes uninhabitable. To be
considered habitable, the EOC should be designed to remain
operational and life-supporting for an extended period of
time under accident conditions, including (as needed):
(1) Breathable atmosphere. The ventilation system should
provide filtration and positive pressure to prevent intake
of contaminants. Equipment should be available to
confirm that the atmosphere remains uncontaminated.
(2) Shielding from radiation.
(3) Backup emergency power.
c. The EOC should have the following:
(1) Controlled access.
(2) Current reference materials such as emergency plans
and procedures, safety analyses, etc.
d. If the EOC is a dual-use facility, the plan or procedures
should provide for rapid conversion for EOC use.
e. If an alternate EOC (AEOC) is designated, the plan should
(1) Its location. It should be located so as to minimize the
possibility that both the EOC and the AEOC would be
rendered uninhabitable by the same event. (E.g. outside
the EPZ, or opposite to the EOC with respect to hazard
