SUMMARY FR slow down or inhibited the spread of fire, the aim of this presentation is to provided a detailed explanation on fire retardant, their types important and some chemistry behind them and what are the major research finding abort this  chemicals and their finishing. INTRODUCTION  Fire is one of the greatest inventions of human beings, no doubt. However, if not managed harm to life and property. Polymeric materials comprises of hydrocarbon chain are prone to burning when expose to fire/ releasing environment heat,  flame and smoke with polymeric all great significance of fire flame retardant maternal (Firs) in our lives can be judiciously realized. Polymeric be made fire/flame retardant (Firs) by the inclusion of micro- and nano-Fir filler or by the incorporation of Fir compounds in their backbone. Learning how these chemicals, and what amount, may cause human health effects in an area of active research although fire retardant can often benefit when added  to certain product, increasing scientific evidence show that many of the chemical may harm animals and humans. Fire is a chemical reaction in which oxygen is combined with a gaseous or vaporous fuel. For a fire to ignite or sustain three component must be present, heat, fuel and oxygen these component are called fire triangle or combustible triangle. When chemical chain reaction is added it is called fire tetrahedron. Fire triangle: the fire triangle or combusting triangle is a three component needed to ignite and sustain a fire. The three ingredient are heat, fuel and oxygen removal of one of this component will reduce the ability of fire to ignite. A fire extinguisher is a handheld active fire protection device usually filled with a dry or wet chemical used to extinguish or control small fires, often in emergencies. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i.e., no escape route, smoke, explosion hazard, etc.), or otherwise requires the equipment, personnel, resource, and /or expertise of a fire  brigade. Typically, a fire extinguisher consist of hand-held cylindrical pressure vessel containing an agent that can be discharged to extinguish a fire. Fire extinguisher manufactured with non-cylindrical pressure vessels also exist but are less common.
