Depending on the situation, your services may or may not be needed by the university after the initial response phase. Contact your dean or vice president before leaving campus (if possible) to notify the campus you are safe and where you may be contacted if you are needed. DO NOT reenter buildings until the buildings have been declared safe! Do not add to the problem by becoming a secondary shock victim. Nothing in the building is more important than your safety.
Having a plan can help minimize your stress during and directly after an event. Talk to you family or loved ones about how you will contact them in an emergency and what each of you can expect from one another. Arrange for family to report their status to someone outside the immediate area because phone lines in the disaster area will be overused and should be reserved for emergency personnel.
