KSC pioneered a two-phase lightning warning
policy. In Phase I, an Advisory is issued that lightning is forecast
within five miles of the designated site within 30 minutes of the
effective time of the Advisory. The 30-minute warning gives personnel in
unprotected areas time to get to protective shelter and gives personnel
working on lightning sensitive tasks time to secure operations in a safe
and orderly manner. A Phase II Warning will be issued when lightning is
imminent or occurring within five miles of the designated site. All
lightning-sensitive operations are terminated until the Phase II Warning
is lifted. This two-phase policy provides adequate lead time for sensitive
operations without shutting down less sensitive operations until the
hazard becomes immediate.
The Lightning Policy is defined by the KSC Lightning Safety Assessment Committee. This group is also responsible for seeing that all structures at KSC, as well as the Space Shuttle, are adequately protected. Structures that particularly need protection against lightning include those that contain ignitable, explosive or flammable materials, and personnel. |
