From the Document: "Maintaining operational and resilient emergency communications is imperative during pandemic response for both public health and safety, as well as community well-being. A critical component of emergency communications are 911 centers--to include emergency communication centers (ECC), public safety answering points (PSAP), public safety communication centers (PSCC), emergency operations centers (EOC), and other public service command centers. A pandemic presents an immediate threat to the ability of these centers to operate effectively. The following guidance is intended to support public safety partners across all levels of government when engaging in the development of pandemic plans that promulgate policies, procedures, governance, resource planning, and contingency considerations."
