The First Draft of NFPA 10 Standard for Portable Fire Extinguishers, 2017 edition, is open for public comment until November 16, 2015. Comments can be submitted through the NFPA website (www.nfpa.org/10next).
For this draft, the technical committee passed 64 revisions, including updated references and clarifications of existing requirements. The following revisions incorporate technical changes to the standard:
Section 4.2, FIRST REVISION NO. 8
The standard will recognize the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) for extinguishers sold and installed outside the United States. Previous editions referenced the Workplace Hazardous Materials Identification System (WHMIS) Reference Manual.
Committee’s Substantiation: Canada is replacing WHMIS with the UN's Globally Harmonized System for Classification and Labeling of Chemicals (GHS).
Section 4.4, FIRST REVISION NO. 71
All extinguishers manufactured prior to 1955 will be considered obsolete and be removed from service. Prior editions limited this to stored pressure extinguishers only.
Committee’s Substantiation: Extinguishers manufactured prior to 1955 are obsolete, were tested to an outdated standard, rated with an outdated rating system, are 60 years old or older, and do not have current manuals or OEM parts available. These extinguishers should be removed from service.
Section 4.4.1, FIRST REVISION NO. 19
All dry chemical stored-pressure extinguishers with an indicated manufacturing date of 1984 or prior will be removed from service immediately. The previous edition allowed them to be removed at the next six-year maintenance or hydrostatic test.
Committee’s Substantiation: All hydrotest dates have passed for stored pressure extinguishers manufactured prior to October, 1984, thus there is no reason to maintain this language.
Section 5.5.7, FIRST REVISION NO. 22
Guidance on selection of portable extinguishers for areas containing oxidizers has been expanded.
Committee’s Substantiation: The proposed change brings NFPA 10 in line with the 2013 edition of NFPA 400 Hazardous Materials Code. There are oxidizers that are incompatible with the application of water. Because the specific type of oxidizer, state of the material, and the quantity present can affect various extinguishment recommendations, referencing the material’s SDS is advisable.
Section 126.96.36.199.1, FIRST REVISION NO. 25
Section 188.8.131.52.2, FIRST REVISION NO. 26
Section 184.108.40.206.3, FIRST REVISION NO. 27
The requirements for visibility of extinguishers and the means of indicating the location of a hidden extinguisher have been clarified and revised.
Committee’s Substantiation: As a minimum, signs or other means need to be provided to indicate the extinguisher location. Fire extinguisher signs are the preferred method for identifying extinguisher locations.
Section 220.127.116.11, FIRST REVISION NO. 28
The means of hanging, mounting, and/or securing an extinguisher will be required to be listed or approved. Brackets will be required to have releasing straps or bands. Field-fabricated hangers and brackets will not be permitted.
Committee’s Substantiation: Text was added to help correct problems identified in the field for inappropriate installations.
Too often building occupants/owners believe an extinguisher can be placed in a general use cabinet along with other business storage. The revised text clarifies that the cabinet must be of an approved type.
The annex was revised to remove the specific construction description of a portable extinguisher stand.
Section 18.104.22.168.6 (new), FIRST REVISION NO. 31
Only surface mounted cabinets or fire-rated cabinets shall be installed in 1-hour and 2-hour fire-resistance-rated walls.
Committee’s Substantiation: Only surface mounted cabinets or fire-rated cabinets which are specially constructed with gypsum board installed on the sides, top, bottom, and back and are intended to be installed in 1-hour and 2-hour fire-resistance-rated walls. Cabinets that are not fire-rated should not be installed in these walls as they would make the entire fire-rated wall non-compliant.
