1、Copyright 2015 National Fire ProtectionAssociation.All Rights Reserved.NFPA115Standard forLaser Fire Protection2016 EditionThis edition of NFPA 115, Standard for Laser Fire Protection, was prepared by the TechnicalCommittee on Laser Fire Protection. It was issued by the Standards Council on January

2、28,2015, with an effective date of February 17, 2015, and supersedes all previous editions.This edition of NFPA115 was approved as anAmerican National Standard on February 17, 2015.Origin and Development of NFPA 115In September 1988, a request was received by the NFPA Standards Council to establish

3、aproject on laser fire protection. At that time, NFPA documents did not address the fire haz-ards of lasers. Existing non-NFPA standards addressed other laser hazards (primarily healthhazards) but did not adequately address the fire hazards involved. In October 1988, theCouncil published a request f

4、or comments on the need for such a project. After reviewingcomments submitted, the Council approved the establishment of a laser fire protectionproject in July 1989. The resultant document (designated NFPA115) was intended to supple-ment existing NFPA documents and other standards involving lasers.

5、Where a particularhazard, such as a flammable liquid, was appropriately addressed by another NFPAdocument,that document was referenced.Lasers can be a significant fire hazard. Class 4 and some Class 3b lasers (classification isfromANSIZ136.1, Safe Use of Lasers)arepowerfulenoughthatthebeamisanigniti

6、onhazard.During use, particularly in the medical field, the laser beam is directly adjacent to combus-tible materials and, in certain clinical procedures, flammable gastrointestinal gases and prep-ping agents. Fire incidents have occurred when the laser beam has impinged on a materialother than the

7、intended target.Additionally, some lasers use flammable liquids as an integral part of their operation. Theflammable liquids are pumped and flow through tubing, which can be quartz or plastic. Bothtypes of tubing are prone to damage, either by breaking or melting, when exposed to a fire.When this oc

8、curs, a flammable liquid pool fire is created.Materials used to fabricate laser systems are often inappropriate with respect to fire safety that is, manufacturers do not always choose component materials with regard to theirignition and heat-release properties. Lasers can involve the use of high-ene

9、rgy power sup-plies. Motors for use with flammable liquids need to be intrinsically safe or of approvedelectrical classification.As part of an ongoing effort to document the fire hazards of lasers, there is a database offires involving lasers. (Documented incidents have occurred in hospitals, resear

10、ch laborato-ries, and industrial applications.) According to the data gathered thus far, the majority ofincidents involve the laser beam as the ignition source. Materials ignited include adjacentcombustibles as well as components of the laser itself. Other incidents have involved compo-nents of the

11、laser overheating or igniting due to a failure of the laser system.In the 1999 edition of this document, changes were made to conform to the NFPAManualof Style.Inaddition,manyofthereferencesto“flammable”liquidswerechangedto“ignitible”liquids because “flammable” was too restrictive.In the 2003 editio

12、n, the document changed from a recommended practice to a standard.Therefore, all of the language within the body of the document was changed to enforceablelanguage, and any recommendations or advisory information was moved to the annexes.The 2008 edition was revised in order to stay current with all

13、 other NFPAdocuments. Thedefinitions were updated and the language was changed where appropriate, in order to add1151NFPAand National Fire ProtectionAssociation are registered trademarks of the National Fire ProtectionAssociation, Quincy, Massachusetts 02169.clarity.Anew requirement was added, which

15、rocedures.The 2016 edition has been updated with the current references and definitions in accordance with the NFPAGlossary of Terms. In addition to the language being revised to clarify requirements, the list of degraded componentsthat could lead to a fire in the Performance Monitoring section was
