Starting in November of 2001, Amerex began manufacturing Model B260 / B262 wet chemical extinguishers with a nozzle grip instead of a wand and with a UL rating of 2A:K instead of 2A:1B:C:K in preparation of new requirements in NFPA 10 – 2002 Edition.
Per NFPA 10 – 2002 edition, there is no requirement to “retrofit” existing Model 260 / 262 extinguishers with the newer nozzle grip, nor is there any requirement for the removal of any earlier Model 260 /262 extinguishers. The 2002 edition of NFPA 10 specifically states:
“4.3.2 Class K Fire Extinguishers for cooking fires……Class K fire extinguishers manufactured after January 1, 2002 shall not be equipped with “extended wand-type” discharge devices.” The standard specifically addresses a manufacturing requirement and cut-off date, not any requirement that could be considered retroactive, or any requirement for placement of extinguishers that were made prior to that date.
There has also been some confusion that statements made in the Annex section of NFPA 10 represent new requirements. The Annex material is for informational purposes only and is not considered to be part of the standard. Again, NFPA 10 specifically states:
“This annex is not a part of the requirements of this NFPA document but is included for informational purposes only.” Another new requirement that is important to note is the specific replacement of existing dry chemical extinguishers. NFPA 10 2002 edition states:
“18.104.22.168 Existing dry chemcial extinguishers without a Class K listing that were installed for the protection of Class K hazards shall be replaced with an extinguisher having a Class K listing when the dry chemical extinguishers become due for either a 6 year maintenance or hydrostatic test.”
