NAFFCO HOW FIRES STARTS This is The Fire Triangle. Actually, it’s a tetrahedron, because there are four elements that must be present for a fire to exist Enough Oxygen to sustain combustion Enough Heat to raise the material to its ignition temperature Some sort of Fuel or combustible material The Free Radicals Chemical Reaction between the other three element
Fire Prevention is based upon keeping these four elements separate.
NAFFCO ELEMENTS OF FIRES can be any combustible material solid,liquid or gas. Most solids and liquids become vapor or gas before they will burn. is the energy necessary to increase the temperature of the fuel to a flash point where sufficient vapor are given off for ignition to occur. the air we breathe is about 21% oxygen, fire only needs an atmosphere with at least 16% oxygen.
NAFFCO Chemical Reaction
Chemical Reaction- a chain reaction can occur when three elements of fire are present in the proper conditions and proportions. Fire occurs when this rapid oxidation, or burning takes place.
NAFFCO How Fire Are Classified CLASS A - Ordinary combustible or fibrous material, such as wood, paper, cloth, rubber and some plastics. CLASS B – Flammable or combustible liquids such as gasoline, kerosene, paint, paint thinners and propane.
CLASS C – Energized electrical equipment, such as appliances, switches, panel boxes and power tools. CLASS D – Certain combustible metals, such as magnesium, titanium, potassium and sodium. These metals burn at high temperature and give off sufficient oxygen to support combustion. They react violently with water or other chemicals, must be handle with care
NAFFCO How Fire Are Classified K
F
U.S Class
B.S Class
CLASS K - fires involving cooking media (grease, vegetable oils, animal oil, or fats) in cooking appliances. This is for commercial kitchens, including those found in restaurants, cafeterias, and caterers. Cooking oil or fat fires have auto ignition temperatures in excess of 340OC and are very difficult to extinguish using conventional extinguishers having a class B capability.
NAFFCO How to Extinguish Fires Class A – Extinguish ordinary combustible by cooling the material below its ignition temperature and soaking the fibers to prevent re-ignition Class B – Extinguish flammable liquids, greases or gases by removing the oxygen, preventing the vapors from reaching the ignition source inhibiting the chemical chain reaction. Class C – Extinguish energized electrical equipment by using extinguishing agent not capable of conducting electrical currents. Class D – Extinguish combustible metals such as magnesium, titanium, potassium and sodium with dry powder, extinguishing agents specially designated for material involved. I most cases, they absorb the heat from the material, cooling it below its ignition temperature
NAFFCO How to Extinguish Fires Class F or K Fire Class F or K – Extinguish auto ignition flames and burning liquid by cooling and reducing below the auto ignition temperature of the burning liquid. The amount of heat involved in liquid above 340OC is high and use of the incorrect extinguisher ca be extremely dangerous.
Extinguisher designed for cooking oil fires typically include “Wet Chemical”, “Dry Chemical” or “Foam” based with special additives. This special materials prevent the flammable vapors reacting with oxygen. This process is called “saponification”
