A written plant fire prevention program should be established and as a minimum should include the following: (a) Fire safety information for all employees and contractors. This information should include, as a minimum, familiarization with fire prevention procedures, plant emergency alarms and procedures, and how to report a fire. (b) Documented regularly scheduled plant inspections including provisions for handling of remedial actions to correct conditions that increase fire hazards. (c) A description of the general housekeeping practices and the control of transient bustibles. Fire experience has shown that transient bustibles can be a significant factor during a fire situation, especially during outages. (d) Control of flammable and bustible liquids and gases in accordance with appropriate NFPA standards. (e) Control of ignition sources including smoking, grinding, welding, and cutting. (See NFPA 51B, Standard for Fire Prevention During Welding, Cutting and Other Hot Work) (f) Fire prevention surveillance. (See NFPA 601, Standard for Security Services in Fire Loss Prevention.) (g) Fire report, including an investigation and a statement on the corrective action to be taken. (See Appendix B.) (h) Fire hazards of materials located in the plant or storage areas identified in accordance with NFPA 704, Standard System for the Identification of the Hazards of Materials for Emergency Response. 24 Fire Protection Program. Testing, Inspection, and Maintenance. Upon installation, all fire protection systems should be preoperationally inspected and tested in accordance with applicable NFPA standards. Where appropriate standards do not exist, inspection and test procedures outlined in the purchase and design specifications should be followed. * All fire protection systems and equipment should be periodically inspected, tested, and maintained in accordance with applicable National Fire Codes174。C). High Voltage Direct Current (HVDC) Converter Station. A facility that functions as an electrical rectifier (acdc) or an inventor (dcac) to control and transmit power in a high voltage work. There are two types of HVDC valves — the mercury arc valve and the presentday technology solid state thyristor valve. Both types of valves present a fire risk due to high voltage equipment that consists of oilfilled converter transformers, wall bushings, and capacitors in addition to various polymeric ponents. Interior Finish. The exposed interior surfaces of buildings including, but not limited to, fixed or movable walls and partitions, columns, and ceilings. Interior finish materials are grouped as Class A Interior Finish and Class B Interior Finish. Interior Finish, Class A. Materials having flame spread 025, smoke developed 0450 when tested in accordance with NFPA 255, Standard Method of Test of Surface Burning Characteristics of Building Materials. Includes any material classified at 25 or less on the flame spread test scale and 450 or less on the smoke test scale when any element thereof, when tested, does not continue to propagate fire. Interior Finish, Class B. Materials having flame spread 2675, smoke developed 0450 when tested in accordance with NFPA 255, Standard Method of Test of Surface Burning Characteristics of Building Materials. Includes any material classified at more than 25, but not more than 75, on the flame spread test scale and 450 or less on the smoke test scale. Labeled. Equipment or materials to which has been attached a label, symbol, or other identifying mark of an anization that is acceptable to the authority having jurisdiction and concerned with product evaluation, that maintains periodic inspection of production of labeled equipment or materials, and by whose labeling the manufacturer indicates pliance with appropriate standards or performance in a specified manner. Limited Combustible. As applied to a building construction material, a material not plying with the definition of nonbustible material that, in the form in which it is used, has a potential heat value not exceeding 3500 Btu/lb ( 106 J/kg) (see NFPA 259, Standard Test Method for Potential Heat of Building Materials), and plies with one of the following: (a) materials having a structural base of nonbustible material with a surfacing not exceeding a thickness of 1/8 in. ( mm) that has a flame spread rating not greater than 50。C) and having a vapor pressure not exceeding an absolute pressure of 40 psi (276 kPa) at 100176。 and hydroelectric plants are addressed in NFPA 851, Remended Practice for Fire Protection for Hydroelectric Generating Plants. 12 Purpose. This document is prepared for the guidance of those charged with the design, construction, operation, and protection of fossil fueled (., coal, gas, or oil) or alternative fueled (., municipal solid waste, refuse derived fuel, biomass, rubber tires, and other bustibles) steam electric generating plants, bustion turbine and internal bustion engine electric generating plants, and high voltage direct current converter stations. This document provides fire prevention and fire protection remendations for the safety of construction and operating personnel, the physical integrity of plant ponents, and the continuity of plant operations. Nothing in this document is intended to restrict new technologies or alternative arrangements. 13 Application. This document is intended for use by persons knowledgeable in the application of fire protection for electric generating plants and high voltage direct current converter stations. 中國最龐大的資料庫下載 Copyright NFPA 中國最龐大的資料庫下載 The remendations contained in this docume
