 The emergency preparedness plan will need to be periodically reviewed and updated and staff will need to be drilled from time to time to ensure that in the event of an emergency, museum staff will be able to effectively carryout the established protocols spelled out in the plan.Museums are advised to conduct annual risk assessments for their collection, building, and surrounding community.The purpose of the assessment is to determine what known factors present a danger to the institution and to try and predict unknown or unexpected factors in order to prevent future damage.
