Consulting-Specifying Engineer - May 2008 - (Page 20) Cover Story Data center fire codes A number of NFPA fire codes are applicable to the data center environment. Each governing a different aspect of the facility from design through maintenance, these standards work in concert to protect your mission critical facility from the threat of a fire. 1. NFPA 10 – Standard for portable fire extinguishers. This code requires the installation of portable fire extinguishers throughout the premises. The use of a portable extinguisher will suppress a fire in its incipient stage and preserve activation of the fixed extinguishing system, conserving resources and expenditure. Hand-held, clean agent fire extinguishers should be used because of their colorless, odorless, non-conductive suppression agent. 2. NFPA 25 – Standard for inspection, maintenance and testing of water-based fire protection systems. This code specifies which tests and frequency of tests need to be performed weekly, monthly and yearly. For example, water flow switches are tested once a year, while control valves are inspected weekly. 3. NFPA 72 – National Fire Alarm Code. This standard outlines the requirements for spacing detection systems, including how many are needed and where they are to be installed as well as the location and installation of audible and visible appliances, addressing their frequency and maintenance requirements. For example, manual pull stations are required within 5 ft. of each exit, while the fire alarm panel must annunciate all the suppression, detection and notification zones. 4. NFPA 75 – Standard for protection of information technology equipment. This code governs data center construction, in regard to the requirements of its fire protection and detection systems, its HVAC equipment and power supply requirements, including disconnecting and grounding. The Standard requires the installation of automatic detection devices both above the suspended ceiling (plenum) and below the raised floor, with a spot type detectors or air sampling system. 5. NFPA 76 – Standard for fire protection of telecommunications facilities. This standard governs the fire protection of telecommunications facilities where telephone, data, cellular, internet, voice over internet protocol and video services are rendered to the public.
