ARMY CORPS OF ENGINEERS NAVAL FACILITIES ENGINEERING COMMAND (Preparing Activity) AIR FORCE CIVIL ENGINEER CENTER Record of Changes (changes are indicated by \1\ .. /1/) Change No. Date Location UFC 4-420-01 1 May 2015 FOREWORD The UNIFIED FACILITIES CRITERIA (UFC) system is prescribed by MIL-STD 3007 and provides planning, design, construction, sustainment, restoration, and modernization CRITERIA , and applies to the Military Departments, the Defense Agencies, and the DoD Field Activities in accordance with USD (AT&L) Memorandum dated 29 May 2002.

2 UFC will be used for all DoD projects and work for other customers where appropriate. All construction outside of the United States is also governed by Status of Forces Agreements (SOFA), Host Nation Funded Construction Agreements (HNFA), and in some instances, Bilateral Infrastructure Agreements (BIA.) Therefore, the acquisition team must ensure compliance with the most stringent of the UFC, the SOFA, the HNFA, and the BIA, as applicable. UFC are living documents and will be periodically reviewed, updated, and made available to users as part of the Services responsibility for providing technical CRITERIA for military construction. Headquarters, Army Corps of Engineers (HQUSACE), Naval FACILITIES Engineering Command (NAVFAC), and Air Force Civil Engineer Center (AFCEC) are responsible for administration of the UFC system. Defense agencies should contact the preparing service for document interpretation and improvements.

3 Technical content of UFC is the responsibility of the cognizant DoD working group. Recommended changes with supporting rationale should be sent to the respective service proponent office by the following electronic form: CRITERIA Change Request. The form is also accessible from the Internet sites listed below.

GOTT, Chief, Engineering and Construction Chief Engineer Army Corps of Engineers Naval FACILITIES Engineering Command JOE SCIABICA, SES MICHAEL McANDREW Director Air Force Civil Engineer Center Director, FACILITIES Investment and Management Office of the Assistant Secretary of Defense (Energy, Installations, and Environment) UFC 4-420-01 1 May 2015 UNIFIED FACILITIES CRITERIA (UFC) NEW DOCUMENT SUMMARY SHEET Document: UFC 4-420-01, ammunition and explosives Storage Magazines Superseding: None Description: This document serves as a reference tool to assist in the planning, siting, and design of ammunition and explosives (AE) storage magazines.

4 It is intended to assist in the selection of an AE storage magazine providing available options and information related to the use of standard designs that have prior approval by the Department of Defense explosives Safety Board (DDESB). This UFC also defines and discusses various issues and requirements that need to be incorporated in the design of these unique FACILITIES . Reasons for Document: UFC 4-420-01 was created for the following reasons: To describe various design issues and requirements that need to be considered in the design of AE storage magazines, including lightning protection, grounding, electrical hazard classification, temperature and humidity controls, ventilation, physical security, etc., To provide a concise description of the various classifications of AE storage magazines and related siting requirements, and To provide a description of the requirements for Service/DDESB site approval for all new AE storage magazines.

5 Impact: UFC 4-420-01 describes unique considerations particular to this facility type that must be correctly incorporated into a design to avoid potentially costly omissions or over-designs. As a supplement to this UFC, the Whole Building Design Guide (WBDG) website provides clear concise descriptions of all available DDESB approved standard designs for AE storage magazines so that they can be easily compared in order to facilitate the selection of the most suitable design for a given site and function: Unification Issues Waterproofing and Drainage: The Navy currently has a prohibition against the use of any types of steel ECM for new construction due to the difficulty of properly waterproofing these magazines. Earth Electrode System (Grounding): The Navy has additional requirements for magazine grounding systems due to interpretation of NFPA 780 requirements. UFC 4-420-01 1 May 2015 Additional Electrical Requirements (Navy Only): The Navy has additional electrical requirements and details for the older standard magazine designs that will bring these designs up to current safety practices.

This UFC serves as a reference tool to assist in the planning and design of ammunition and explosives (AE) storage magazines for the Department of Defense (DoD), by providing definitions and information related to the design, selection, and siting of these unique FACILITIES .

9 This UFC is intended to assist in the selection of a magazine design by providing available options and information related to the use of designs that have been used in the past and have been approved by the Department of Defense explosives Safety Board (DDESB). The individual DoD Services can also provide additional guidance on the selection of magazine designs. A web site designed to be a companion resource to this UFC is located on the Whole Buildings Design Guide and can be accessed at: . This web site provides the following additional information and resources: Available electronic copies of referenced military regulations, manuals and standards. Available design drawings, approval letters, and specifications for 7-Bar and 3-Bar Earth-Covered Magazines (ECM) that have been approved for new construction. Available drawings and related information for the designs of 7-Bar and 3-Bar ECM that are no longer approved for new construction but still in use.

10 Available drawings and related information for the designs of ECM and Aboveground magazines (AGM) and containers that have been approved for restricted use. A listing of the existing magazine designs that are classified as undefined Available drawings for barricade design utilizing various construction materials. Links to additional related resources and publications. This UFC, when used with the companion web site, provides planners and designers of AE storage FACILITIES access to up to date information and resources needed in the selection and design of new storage magazines and in the evaluation of existing FACILITIES . 1-2 BACKGROUND. The DDESB has established minimum AE safety standards for personnel and property that have the potential of being exposed to the effects of an accidental explosion. These standards govern the design, construction, and use of all AE storage FACILITIES within the DoD.
