UL300 and Kitchen Fire Protection Systems

Commercial kitchens contain all the elements necessary for a fire. Grease and cooking oils provide the fuel. Oxygen is always available and heat can come from a variety of sources, ranging from an open cooking flame to electrical shorts. Fire can occur on cooking surfaces and in hard-to-reach areas like hoods, plenums, vents and ductwork.


In recent years, the development of high-efficiency cooking appliances and a switch to vegetable cooking oils have increased the threat and occurrence of fires that are more difficult to extinguish. Since many commercial kitchens operate long hours and are staffed with people untrained in fire fighting, it is imperative to have a fire protection system that combines both automatic fire depletion and suppression.

Call one of our factory trained professionals for an estimate today.


The recent demand for a low-fat diet has profoundly changed the effectiveness of conventional extinguishing agents. Additives which make low-fat oils palatable, coupled with super-insulated deep fat fryers have rendered most dry chemical agents ineffective for fighting these types of fires. The concern has been so significant that a UL 300 test requirement was enacted calling for new agents and new designs for all systems installed or modified as of November 21, 1994.

DeLau Fire Services can survey your system and determine if it meets these new requirements. We can also inspect and maintain your system(s) in accordance with the National Fire Protection Association’s pamphlets 17, 17A and 96.
