The definition of NFPA 37 vs NFPA 850 be explained please ? At what level does a the "Power Station" become under NFPA 850?
Read the scope
1.1 Scope. This standard establishes criteria for minimizing the hazards of fire during the installation and operation of stationary combustion engines and gas turbines.
1.1 Scope. This document provides recommendations for fire prevention and fire protection for electric generating plants and high voltage direct current converter stations, except as follows: Nuclear power plants are addressed in NFPA 805, Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants; hydroelectric plants are addressed in NFPA851, Recommended Practice for Fire Protection for Hydroelectric Generating Plants; and fuel cells are addressed in NFPA 853, Standard for the Installation of Stationary Fuel Cell Power Systems.
Thank you for the reply, the goal was to better define the "scope" as to at what level would the "Generation Plant" be defined vs a "Standby Combustion Engine" ? As both could be used in the same situation with the use of "micro grid technology".
Not my area, but I still go back to the scope of each document.
To me 37 talks about engines only::
This standard applies to stationary combustion engines and gas turbines. This standard also applies to portable engines that remain connected for use in the same location for a period of one week or more.
This standard applies to new installations and to those portions of existing equipment and installations that are modified.
The effective date of application of this standard is not determined by NFPA. All questions related to applicability shall be directed to the authority having jurisdiction.
NOT generating power.
Where as 850 is specific to generating electricity::
This document is prepared for the guidance of those charged with the design, construction, operation, and protection of electric generating plants and high voltage direct current converter stations that are covered by the scope of this document.
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.
You could have a stand by combustion engine that might fall under 37, but if not at a generator plant, 850 would not apply.
Yes if there is a combustion engine at a generator plant than 37 and 850 could both apply.
Plus 850 is for fire protection requirements.
As in some NFPA documents, not all terms are defined, or when the document would apply.
Sometimes the document applies if an AHJ has adopted it, or a contract says comply with NFPA .......
Not sure if the Doc history helps you any::::
Origin and Development
The Committee on Non-Nuclear Power Generating Plants was organized in 1979 to have primary responsibility for documents on fire protection for non-nuclear electric generating plants. Begun early in 1980, the first edition of NFPA 850 was officially released in 1986 as the Recommended Practice for Fire Protection for Fossil Fueled Steam Electric Generating Plants.
The second edition of NFPA 850 was issued in 1990 under the revised title of Recommended Practice for Fire Protection for Fossil Fueled Steam and Combustion Turbine Electric Generating Plants. This second edition incorporated a new Chapter 6 on the identification and protection of hazards for combustion turbines.
In 1991 the committee changed its name to the Technical Committee on Electric Generating Plants. This simplified name was made to reflect the committee’s scope to cover all types of electric generating plants except nuclear.
The 1992 edition of NFPA 850 incorporated a new Chapter 7 on alternative fuel electric generating plants. As part of these changes, the document title was revised to the Recommended Practice for Fire Protection for Electric Generating Plants. Various other technical and editorial changes were also made.
The 1996 edition of the standard added a new Chapter 8 on fire protection for high voltage direct current (HVDC) converter stations. In addition, the title was changed to Recommended Practice for Fire Protection for Electric Generating Plants and High Voltage Direct Current Converter Stations to incorporate the new chapter.
From Chapter 10
Although it is intended that these recommendations are to be applied to fixed, nonresidential ICEs only, larger portable units (often trailer mounted) can include fire detection and suppression systems to limit damage from fire. The recommendations of this chapter can be used as guidance for these units as well.
It is not obligatory for power plants to fall under NFPA 850 because it is not a standard at all.
Look at the title of this document: it is called "Recommended practice", and chapter 3 discloses the meaning of this term: 3.2.5. Recommended Practice. A document that is similar in content and structure to a code or standard but that contains only nonmandatory provisions using the word “should” to indicate recommendations in the body of the text.
So it is good to use NFPA as a set of recommendations, but not much else.
I mean NFPA 850, of course
