What signifies a fire extinguisher meets UL 300 compliance?

A fire extinguisher that meets UL 300 compliance is indicated by a yellow tag. UL 300 refers to a standard established by Underwriters Laboratories that specifically pertains to fire extinguishers designed for use in commercial kitchens, particularly for the protection of cooking appliances that can be a source of flammable liquids and gases, such as deep fryers.

The yellow tag signifies that the extinguisher has been tested and approved for use with cooking oils and has the appropriate extinguishing agents necessary to effectively handle flammable liquid fires, including those related to the new cooking technologies that utilize higher temperatures and different fuel sources than traditional methods.

In contrast, other color tags are used to signify different types of compliance or inspections, which do not apply specifically to UL 300 standards. Thus, the yellow tag is distinctively important for compliance in commercial kitchen fire safety standards.
