Preparation for a SIP order should include the following:

Update the emergency action plan. Write an SIP component into the Emergency Action Plan. This component should give detailed information about what to do in the event of a SIP order.
Designate an appropriate room as the “safe room.” It should be an interior room with few (or no) windows, an adjoining bathroom, and storage for SIP supplies. It should be large enough to accommodate the required number of people and preferably have access to TV/CNN.
