FIRE PROTECTION/SAFETY CHAPTER 3: COMMUNICATION SITE BUILDING DESIGN AND INSTALLATION 3.12.8 POWER SOURCES The primary power source for the fire extinguishing system's operation and control shall have the capacity for intended service and shall be reliable. Where failure of the primary power source would jeopardize the protection provided, a secondary (standby) power source shall supply energy to operate the system for a period of 24 hours and be capable of operating the extinguishing system continuously for the full designed discharged period. The secondary (standby) power shall automatically transfer to operate the system within 30 seconds of the loss of primary power. 3.12.9 FIXED SYSTEMS COMPARISON TABLE 3-2 FIRE SUPPRESSION SYSTEMS If a new system is being installed or an existing fixed fire-extinguishing system is being replaced, always check with local fire prevention authorities and a competent fire protection engineer first. Be ready to supply information about the material composition of the building or housing structure, occupancy of the structure, environment, and equipment that needs to be protected. Ask for their recommendations on the type of extinguishing systems needed, along with any advantages and disadvantages of a particular system. Some of the more common fixed systems currently used at communication sites are listed in Table 3-2. The advantages and disadvantages of each type are also described. Type Advantages Disadvantages Water Extinguishing (Water Sprinkler) FE-13 (HFC-23) • Upon detection of a fire condition, a “dry pipe” type of system removes source power to the room and then opens a master valve to fill the overhead sprinklers. (The “dry pipe” system is preferable to a “wet pipe” system, which has the chance of water leakage and resultant equipment damage and possible electrical shock.)· • No adverse environmental impact. Clean Agent Extinguishing System • Environmentally friendly replacement of Halon 1301-based systems. • Advantage over CO2 systems, due to FE-13 lack of oxygen displacement characteristic. • Electrically nonconductive and residuefree. No cleanup is required after discharge and system downtime can be kept to a minimum. • The storage cylinder(s) may be stored away from the protected area. • Storage cylinders can be stored in a wide range of temperatures; containers need not be stored in protected places at room temperature. • System recharge is less expensive than alternative fluorocarbon agents. • If power connections are made beneath raised floors, waterproof electrical receptacles and connections are required. • Either type of water sprinkler system could cause electronic equipment damage and will require an extensive cleanup effort. • Upon discharge, system downtime can be lengthy. • May not be readily attainable or easily refilled in certain areas. • Typically much more costly to purchase and maintain than water systems. • When released under fire conditions hydrofluoric acid (HF) can be produced. 3-28 68P81089E50-B 9/1/05

System downtime can be kept to a minimum. • When compared with Halon 1301, FM200 systems require minimal additional floor storage space. • Environmentally friendly replacement of Halon 1301-based systems. It has no Ozone Depleting Potential, Global Warming Potential, or Atmospheric Lifetime. • No toxic or corrosive decomposition products. • Electrically nonconductive and residuefree; no cleanup is required after discharge. System downtime can be kept to a minimum. • Because INERGEN is stored as a gas, it can be stored at a substantial distance form the risk area, where more space is available. • System recharge can be more expensive than other types of extinguishing agents. • When released under fire conditions hydrofluoric acid (HF) can be produced. When compared with Halon 1301 and FM200 systems, INERGEN systems require more cylinders and additional floor storage space. The following safety equipment shall be permanently located inside all equipment shelters and in or within close proximity to tenant improvement equipment rooms: • First aid kits • Eye wash station • Battery safety equipment including personal protection equipment in any area with wet cell batteries • Construction/installation safety equipment • Safety markings and barriers NOTE: It is strongly recommended that all employees obtain formal training and certification in First Aid and cardiopulmonary resuscitation (CPR). 68P81089E50-B 9/1/05 3-29
