UL Warns of Unauthorized UL Marks on Fire Extinguishing Balls

NORTHBROOK, IL, (April 29, 2022) - The following is a notification from UL that fire extinguishing balls being sold through various retailers bear counterfeit UL Certification Marks or unauthorized references to UL. Fire extinguishing balls are sphere-shaped devices intended to suppress fire through self-activation or by being thrown into an active fire. UL has not evaluated fire extinguishing balls, nor does UL plan to develop requirements to certify fire extinguishing balls.    

Some fire extinguishing ball packaging bears UL file number “EX16029” for Delei Fire Inc. dry chemical agents for fire extinguishers. Delei Fire Inc. does not manufacture fire extinguishing balls and has no affiliation with this type of product. 

Remedy – UL recommends that users keep a UL Certified fire extinguisher in a readily accessible location to use in the event of a fire.
