Construction Standards for Fire Protection and Communication Equipment Rooms
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. This standard provides requirements for fire protection of telecommunications facilities providing telephone, data, internet transmission, wireless, and video services to the public as well as life safety for the occupants plus protection of equipment and service continuity. This process brings together volunteers representing varied viewpoints a d interests to achieve consensus on fire and other safety issues. While the NFPA administers the process and establishes rules to promote fairness in the. Fire safety is addressed in specific OSHA standards for recordkeeping, general industry, maritime, and construction.
