K-GUARD® Kitchen-Class Fire Extinguishers

Ansul Portable Class K Fire Extinguishers

Kitchen Fires Keep Getting Hotter

The preparation of low cholesterol, low-fat foods requires the use of hotter burning vegetable oils. And highly insulated, slow-cooling appliances have become more commonplace. As a result, fires in today's appliances are more difficult to extinguish and secure than in the past.

The PRX™ Agent Solution

K-GUARD™ extinguishers contain PRX™ Liquid Fire Suppressant, a specially formulated, aqueous solution of inorganic salts. In addition to knocking down the flame and forming a vapor-securing blanket, PRX agent provides a cooling effect that aids in the extinguishing and securing process. For these reasons, Ansul uses this same liquid agent in both our K-GUARD™ extinguishers and our PIRANHA™ restaurant fire suppression systems.

Meets Tough UL Standards

K-GUARD™ fire extinguishers are listed by Underwriters Laboratories (UL) and UL of Canada (ULC) after meeting or exceeding UL 8: Standard for Foam Extinguishers and UL 711: Standard for Rating and Fire Testing of Fire Extinguishers. The new UL "K" rating is based on fire testing on commercial fryers, the toughest fires to extinguish in a restaurant or commercial kitchen.

Complies with NFPA 10 (1998)

NFPA 10: Standard for Portable Fire Extinguishers (1998 Edition) requires that "Fire Extinguishers provided for the protection of cooking appliances that use combustible cooking media (vegetable or animal oils or fats) shall be listed and labeled for Class "K" fires." This applies to all extinguishers installed specifically for these hazards after June 30, 1998. K-GUARD extinguishers meet these requirements.

Typical applications include:

  • restaurants
  • convenience stores
  • food courts
  • cafeterias
  • and many others
