IEEE 979-201 pdf download IEEE Guide for Substation Fire Protection
Most control houses should have a minimum of two exits. These exits should be located at opposite ends of the buildingto prevent the possibility of personnel being trapped by a fire. These doors should open outward and be equipped withilluminated exit signs.Panel and equipment arrangements should be designed so personnel can exit the equipment arerfrom both ends. Additional guidance can be found in ANSINFPA 70-1993 (B22),ANSI/NFPA 101-1994 (B26), andANSI/NFPA 101A-1995 B27
2.4 Door locks
Panic hardware on all doors should override any exterior lock or padlock to allow egress from the building, Thisfeature is recommended because personnel may enter the building without first unlocking all of the exterior doors.
2.5 Fire extinquishers
2.5.1 Portable extinquishers
Portable fire extinguishers should be located in accordance with ANSI/NFPA 10-1994 (B2]. Locations adjacent tonormal entrance/exit doors are suggested. See clause 7. for guidance in selection of the type of extinguishing agent.
2.5.2 Fixed extinguishing systems
Local fire codes may require fixed fire-extinguishing systems, or their installation may be necessary due to the criticalocation or type of substation. Guidance in selection of this type of system may be found in clause 7.
2.6 Alarms
It may be desirable to equip unattended substations with smoke or heat detectors to sense a fire. Duct smoke detectors.installed in the return ducts of heating and cooling equipment, provide an effective means of detecting fire. Thedetectors should activate an audible/visual fire alarm at the substation site. the master station (if the substation isequipped with supervisory control equipment), and, if desired, the local fire station. Attended substations should beequipped with similar devices that should actuate a local alarm.See clause 6. for guidance in the selection of thedetection system.
27 Combustible materials
The use of combustible materials with flame-spread, fuel-contributed, and smoke-developed ratings greater than 2.
should be avoided in the selection of desks, chairs, filing cabinets, storage boxes, display boards, building insulation.
interior wall panels, mounting boards, etc. The flame spread is calculated utilizing ANSI/NFPA 255-1990 (B29).
271 Housekeeping
Good housekeeping practices should be followed to eliminate the accumulation of combustible materials, e.g.discarded papers, prints, cups, newspapers, etc. Waste cans should be fire approved and self-closing
2.7.2 Storage
The storage of paper products, cleaning fluids, and other combustible materials in a control building should beminimized. If stored in the control building, they should be kept in a separate area having a minimum 1 h rating toprevent a fire from spreading to the main control and relay areas. Flammable liquids should be stored only in safetcans approved by Underwriters Laboratories. Guidance for the storage of flammable liquids can be found in ANSlNFPA 30-1993[B18].
