Many people think of a house of worship as a safe area where violence and emergencies cannot affect them. However, violence in houses of worship is not a new phenomenon. In addition to violent acts, fires, tornados, floods, hurricanes, earthquakes, and arson also affect houses of worship. With many incidents occurring with little to no warning, many houses of worship are developing and updating plans and procedures to ensure the safety and security of their congregations, staff, and facilities. In collaboration with other houses of worship and community partners (i.e., governmental entities that have a responsibility in the plan, including first responders, public health officials, and mental health officials), houses of worship can take steps to plan for these potential emergencies through the creation of an emergency operations plan (EOP). Additionally, community organizations and private sector entities may have a role in the plan. Houses of worship are distinctive settings in that congregants share a common bond and have a predisposition to volunteer. The demographics of a congregation often mean that children and the elderly are present and may need assistance. This guide provides houses of worship with information regarding emergency operations planning for the spectrum of threats and hazards they may face. It discusses actions that may be taken before, during, and after an incident in order to reduce the impact on property and any loss of life and it encourages every house of worship to develop an EOP. The Departments issuing this guidance are providing examples of good practices and matters to consider for planning and implementation purposes. The guidance does not create any requirements beyond those included in applicable law and regulations, or create any additional rights for any person, entity, or organization. Moreover, the Departments fully understand that congregations may approach some of these issues differently than government and other community organizations. At the same time, the Departments would like to assist congregations that are interested in emergency operations planning, and this guidance is offered in that spirit. The information presented in this document generally constitutes informal guidance and provides examples that may be helpful. The inclusion of certain references does not imply any endorsement of any documents, products, or approaches. Other resources may be equally helpful. It is recommended that planning teams responsible for developing and revising a house of worship's EOP use this document to guide their efforts. To gain the most from this guide, users should read the entire document prior to initiating their planning efforts and refer back to it throughout the planning process.1 The guide is organized in four sections: The principles of emergency operations planning A process for developing, implementing, and continually refining a house of worship's EOP with community partners A discussion of the form and function of a house of worship's EOP A closer look that discusses house of worship emergency planning in the event of an active shooter situation. This guide is designed to be scalable for use by small to large-sized houses of worship in order to help navigate the planning process. Used in its entirety, this guide provides information on the fundamentals of planning and their application. At a minimum, houses of worship are encouraged to complete the planning process and develop a basic plan. This guide does not impose any new Federal requirements. While some Federal requirements may apply to houses of worship that receive Federal funding, they are not addressed in this document. For houses of worship that also operate a school, please see the Guide for Developing High-quality School Emergency Operations Plans for planning considerations specific to the school environment.
