K-GUARD Fire Extinguisher

We are pleased to announce that the ANSUL K-GUARD Fire Extinguisher is now 2-A: K rated.  Choose ANSUL K-GUARD as your preferred restaurant fire extinguisher and meet NFPA 10 solid fuel cooking requirements for a firebox size of 5 ft3 or less.  This upgraded 2-A rating also means compliance with NFPA 10 fire extinguisher size and placement for Class A Hazards which means you can protect the kitchen area without additional extinguishers needed.

Newer, more efficient cooking appliances, plus the use of non-saturated cooking oils, require a fire extinguishing agent that will not only smother a fire but also provide a cooling effect.

Rated for Class K fires, K-GUARD Fire Extinguishers are designed specifically to fight some of the toughest fires—hot grease, cooking oil and fat fires in the kitchens and food-prep areas of restaurants, convenience stores, food courts, hospitals, school cafeterias and other facilities. Typical appliances that benefit from K-GUARD protection include fryers, griddles, ranges, broilers, char-broilers, woks and more.

K-GUARD extinguishers contain ANSULEX Low pH  Liquid Fire Suppressant, a specially formulated, aqueous solution. In addition to knocking down the flame and forming a vapor-securing blanket, ANSULEX agent provides a cooling effect that aids in extinguishment and securement of hot cooking fuels. (ANSUL Low pH agent is used in both the K-GUARD extinguishers and R-102 restaurant fire suppression systems.)
